AB  - Crevna mikrobiota ima važnu ulogu u održavanju homeostaze koju ostvaruje preko interakcija sa imunskim
sistemom i gastrointestinalnim traktom. Toksične supstance ostvaruju direktan štetni efekat na sastav
i funkcionalnost crevne mikrobiote. Kadmijum (Cd) je metal sa izraženom toksičnošću, koji se povezuje
sa brojnim oboljenjima. U našoj studiji je predložen mehanizam zaštite koji bi se ostvario posredstvom
bakterijskih egzopolisaharida (EPS) izolovanih iz soja Lactiplantibacillus plantarum BGAN8, a bazira se
na visokom afinitetu adsorpcije kadmijumovih jona. Ciljevi rada su bili utvrđivanje efekata produženog
delovanja kadmijuma na sastav crevne mikrobiote Dark agouti (DA) pacova, kao i izučavanje efekta
EPS-AN8 na ublažavanje takvih štetnih efekata.
Pacovi su kroz vodu unosili nižu (5 ppm) i višu (50 ppm) dozu kadmijuma, dok je EPS-AN8 (100 μg/ml) dat
kroz hranu za životinje. Totalna DNK je izolovana iz lumena duodenuma i 16S rDNK amplikon je sekvenciran
strategijom uparenih krajeva na Illumina NovaSeq platformi. Dodatno, praćene su promene u
inflamaciji i oksidativnom stresu homogenata duodenuma. Kadmijum je favorizovao rast oportunističkih
patogenih bakterija poput pripadnika rodova Blautia, Prevotella, Alloprevotela, Bacteroides, dok je
relativna zastupljenost laktobacila bila značajno smanjena. Obe doze kadmijuma su stimulisale produkciju
proinflamatornih citokina (IL-1β, TNF-α i IFN-γ) i povisile nivo oksidativnog stresa (MDA, CAT i
GST). Oralni unos EPS-AN8 je značajno ublažio sve navedene promene. Oralna izloženost kadmijumu
uzrokuje nedvosmislene promene u sastavu mikrobiote, koje mogu biti praćene i pojačanim nivoima
inflamacije i oksidativnog stresa. Nasuprot tome, istovremeni unos EPS-AN8 redukuje pojavu takvih
promena.
AB  - The gut microbiota has important role in maintaining homeostasis via its effect on the immune system
and healthy gastrointestinal tract. Environmental toxicants directly influenced the changes in gut microbiota
composition. Cadmium (Cd) is a hazard, world widely distributed metal. We have proposed
the putative mechanism of protection against Cd harmful effect in the organism by using exopolysaccharides
derived from Lactiplantibacillus plantarum BGAN8 (EPS-AN8) which has great ability to sequester Cd ions.
Aims of our study were to examine Cd related changes in the gut microbiota of Dark agouti (DA) rats after
prolonged oral exposure (30 days) to this metal and to determine impact of EPS-AN8 in preventing
those changes.
Rats were given via water lower (5 ppm) and higher (50 ppm) Cd’s dose. In paralel, EPS-AN8 was administrated
through food (100 μg/ml). Total DNA from duodenum was isolated and PCR amplicon for 16SrRNA was
sequenced on Illumina NovaSeq paired end platform. Moreover, we have followed changes in
oxidative stress and inflammation in duodenum. Cd favored growth of opportunistic pathogen bacteria
genera (Blautia, Prevotella, Alloprevotela, Bacteroides) while the relative abundance of lactobacilli was
decreased. The both doses of Cd increased production of inflammatory cytokines (IL-1β, TNF-α, and
IFN-γ). Also, parameters of oxidative stress were significantly upregulated (MDA, CAT, and GST).
All the mentioned changes were alleviated by EPS-AN8. Oral exposure to Cd lead to inevitable changes
in the microbiota structure followed by inflammation and oxidative stress of surrounding tissue, while
administration of EPS-AN8 reversed those changes.

AB  - Since the realization that the lungs are not sterile but are normally inhabited by various bacterial species, studies have been conducted to define healthy lung microbiota and to investigate whether it changes during lung diseases, infections, and inflammation. Using next-generation sequencing, we investigatedbacterial microbiota from whole lungs in two rat strains (previously shown to differ in gut microbiotacomposition) in a healthy state and during pulmonary infection caused by the opportunistic fungusAspergillus fumigatus. No differences in alpha diversity indices and microbial composition between DAand AO rats before infection were noted. Fungal infection caused dysbiosis in both rat strains, characterizedby increased alpha diversity indices and unchanged beta diversity. The relative abundance ofgenera and species was increased in DA but decreased in AO rats during infection. Changes in lungmicrobiota coincided with inflammation (in both rat strains) and oxidative stress (in DA rats). Disparateresponse of lung microbiota in DA and AO rats to pulmonary fungal infection might render these two ratstrains differentially susceptible to a subsequent inflammatory insult.

Наше пређашње студије су показале да егзополисахарид изолован из соја Lactiplantibacillus plantarum BGAN8 (EPS-AN8) показује висок афинитет за везивање јона кадмијума у воденом раствору и остварује значајан ниво in vitro заштите Caco-2 ћелија од његових токсичних ефеката. Имајући у виду да је за општу популацију најзаступљенији унос кадмијума исхраном, у овој студији је праћен паралелни ефекат уноса кадмијума (кроз воду) и EPS-AN8 (кроз храну) у DA пацовима. Након 30 дана третмана, утврђено је да је унос EPS-AN8 допринео сниженом нивоу депонованог метала у бубрезима, јетри и крви, а повећаном садржају у фекалном материјалу. Такође, микрографије дуоденума, бубрега и јетре су указале на ниже степене кадмијумом индукованих оштећења.

С обзиром да орални унос кадмијума доводи до значајних промена у цревној микробиоти, изоловали смо тоталну DNK из дуоденума и секвенцирали 16S rDNK ампликон на Illumina NovaSeq платформи. Примећено је да унос EPS-AN8 ублажава појаву промена у релативној заступљености бактеријских родова и врста карактерисичних за излагање кадмијуму, попут пораста броја опортунистичких патогених бактерија и смањења бројности лактобацила.

Aspergillus fumigatus infection on bacterial homestasis in these organs in
Dark Agouti (DA) and Albino Oxford (AO) rats known to develop different
immune responce to the fungus.
Methods:
16S rRNA amplicon sequencing of the V3-V4 hypervariable region.
Enzyme-linked immunosorbent assay for cytokine content (IL-10, IL-6, TNF,
IL-1beta, IL-17 i IFN-gamma) in lung and gut homogenats, and plasma (IL-
6, IL-17, TNF). Myeloperoxidase, catalase, glutathione S-transferase and
content of reduced glutathione in lung homogenates.
Results:
No initial differences in lung bacterial microbiota between healthy DA
and AO rats exists, but A. fumigatus infection resulted in increase in
alpha diversity (without effect on bacterial composition) in both strains.
Changes in relative abundance at genus and species level were expressed
differently (increased in DA, decreased in AO). Dysbiosis in lung coincided
with increase of IFN-gamma, IL-17 and MPO in both strains, and increase
oxidative stress solely in DA. Gut inflammation was noted in both strains,
while bacterial dysbiosis only in DA.
Conclusions:
Pulmonary fungal infection resulted in bacterial dysbiosis in lung (in both
rat strains), and gut (solely in DA). Noted lung and gut inflammation in
these two rat strains, coexisted with different effects on bacterial
homeostasis, which could be due to different genetic background or
bacterial composition prior infection.

AB  - Cadmium (Cd) is a highly toxic metal that is distributed worldwide. Exposure to it is
correlated with a vast number of diseases and organism malfunctions. Exopolysaccharides (EPS)
derived from Lactiplantibacillus plantarum BGAN8, EPS-AN8, previously showed great potential for
the in vitro protection of intestinal cells from this metal. Here, we investigated the potential of food
supplemented with EPS-AN8 to protect rats from the hazardous effects of Cd exposure. After thirty
days of exposure to lower (5 ppm) and higher (50 ppm)-Cd doses, the administration of EPS-AN8 led
to decreased Cd content in the kidneys, liver, and blood compared to only Cd-treated groups, whereas
the fecal Cd content was strongly enriched. In addition, EPS-AN8 reversed Cd-provoked effects on
the most significant parameters of oxidative stress (MDA, CAT, GST, and GSH) and inflammation
(IL-1 , TNF- , and IFN-
) in the duodenum. Moreover, micrographs of the duodenum were in line
with these findings. As the gut microbiota has an important role in maintaining homeostasis, we used
16S rRNA amplicon sequencing and investigated the effects of Cd and EPS-AN8 on one part of the
microbiota presented in the duodenum. Although Cd decreased the growth of lactobacilli and mostly
favored the blooming of opportunistic pathogen bacteria, parallel intake of EPS-AN8 reversed those
changes. Therefore, our results imply that EPS-AN8 might be extremely noteworthy in combatting
this toxic environmental pollutant.

AB  - While gut microbiota dysbiosis has been linked with autism, its role in the etiology of other neurodevelopmental disorders (NDD) is largely underexplored. To our knowledge this is the first study to evaluate gut microbiota diversity and composition in 36 children from the Republic of Serbia diagnosed with NDD and 28 healthy children. The results revealed an increased incidence of potentially harmful bacteria, closely related to Clostridium species, in the NDD patient group compared to the Control group: Desulfotomaculum guttoideum (P < 0.01), Intestinibacter bartlettii (P < 0.05), and Romboutsia ilealis (P < 0.001). On the other hand, significantly lower diversity of common commensal bacteria in the NDD group of patients was noticed. Enterococcus faecalis (P < 0.05), Enterococcus gallinarum (P < 0.01), Streptococcus pasteurianus (P < 0.05), Lactobacillus rhamnosus (P < 0.01) and Bifidobacteria sp. were detected in lower numbers of patients or were even absent in some NDD patients. In addition, butyrate-producing bacteria Faecalibacterium prausnitzii (P < 0.01), Butyricicoccus pullicaecorum (P < 0.05), and Eubacterium rectale (P = 0.07) were less frequent in the NDD patient group. In line with that, the levels of fecal short chain fatty acids (SCFAs) were determined. Although significant differences in SCFA levels were not detected between NDD patients and the Control group, a positive correlation was noted between number of rDNA amplicons obtained with universal primers and level of propionic acid, as well as a trend for levels of total SCFAs and butyric acid in the Control group. This correlation is lost in the NDD patient group, indicating that NDD patients' microbiota differs from the microbiota of healthy children in the presence or number of strong SCFA-producing bacteria. According to a range-weighted richness index it was observed that microbial diversity was significantly lower in the NDD patient group. Our study reveals that the intestinal microbiota from NDD patients differs from the microbiota of healthy children. It is hypothesized that early life microbiome might have an impact on GI disturbances and accompanied behavioral problems frequently observed in patients with a broad spectrum of NDD.

AB  - Gut microbiota dysbiosis has been considered the essential element in the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). Antibiotics were administered orally to Dark Agouti (DA) rats early in their life with the aim of perturbing gut microbiota and investigating the effects of such intervention on the course of EAE. As a result, the diversity of the gut microbiota was reduced under the influence of antibiotics. Mainly, Firmicutes and Actinobacteria were replaced by Proteobacteria and Bacteroidetes, while decreased proportions of Clostridia and Bacilli classes were accompanied by an increase in Gamma-Proteobacteria in antibiotic-treated animals. Interestingly, a notable decrease in the Helicobacteraceae, Spirochaetaceae and Turicibacteriaceae was scored in antibiotic-treated groups. Also, levels of short chain fatty acids were reduced in the faeces of antibiotic-treated rats. Consequently, aggravation of EAE, paralleled with stronger immune response in lymph nodes draining the site of immunization, and increased inflammation within the CNS, were observed in antibiotic-treated DA rats. Thus, the alteration of gut microbiota leads to an escalation of CNS-directed autoimmunity in DA rats. The results of this study indicate that antibiotic use in early life may have subsequent unfavourable effects on the regulation of the immune system.

AB  - Objective
Our previous studies with Lactobacillus paraplantarum BGCG11 probiotictreatment
of diabetic rats showed decreased hyperglycemia and
ameliorating effect on diabetes-associated damage of liver and kidneys.
Hence, the aim of this study was to reveal the effects of BGCG11 probiotic
on gut microbiota composition and monitoring the insulin production in
pancreatic islets in diabetic rats.
Methods
Experiments were performed on albino Wistar rats divided into four groups:
ND – non-diabetic control, D – streptozotocin (STZ) induced diabetes;
P/D/P – BGCG11 pretreatment; D/P – BGCG11 treatment. The rats were
orally administered with BGCG11, one week before (P/D/P) and after the
STZ injection, for four weeks (P/D/P and D/P). Total DNA was isolated from
all fecal samples and rDNA amplicons were analyzed by DGGE and 16S
rDNA genes sequencing. For immunohistochemical analysis, slides were
stained with anti-insulin antibody and secondary antibody coupled with
horseradish peroxidase.
Results
The results revealed the higher diversity of gut microbiota in D/P group
comparing to D group, as well as the higher prevalence of Flintibacter
butyricus (the major butyric producer), Acetatifactor muris (present in
obese mouse) and Eisenbergiella massiliensis (found in obese woman),
while the lipolytic bacterium Aestuariispira insulae was more prevalent in
diabetic rats. In both, P/D/P and D/P group, increased number of positive
immunoreactions of β-cells for anti-insulin antibodies was displayed in
compare to D group with islet atrophy.
Conclusions
The results of this study suggest that the positive effect of BGCG11 on
STZ-induced diabetes in rats could be annotated to its protective role on
the integrity of fecal microbiota.

diabetic rats. In both, P/D/P and D/P group, increased number of positive
immunoreactions of β-cells for anti-insulin antibodies was displayed in
compare to D group with islet atrophy.
Conclusions
The results of this study suggest that the positive effect of BGCG11 on
STZ-induced diabetes in rats could be annotated to its protective role on
the integrity of fecal microbiota.",

AB  - Objective: Clinical reports indicated increased incidence of gastrointestinal (GI) disturbances and dysbiosis in children with neurodevelopmental disorders (NDD) as well as acceleration of the recovery after the dysbiosis treatment. The aim of this study was to evaluate gut microbiota diversity and to identify bacterial strains which incidences were different between patients’ and control group. This is the first study evaluating gut microbiota diversity and composition in children with NDD.
Conclusions: Our study reveals that the intestinal microbiota from children with NDDs differs from the microbiota of healthy children. Similarity of microbiota composition in patient groups with similar neurological and behavioral symptoms indicate that intestinal microbiota might have role in pathophysiology of NDD. Supplementation with several health promoting strains, could be safe adjuvant therapy in treatment of NDD accompanied with GI disturbances.

AB  - The gut microbiome is very important for hosts’ proper essential functions, as microbiota influence both near and distant organs and disruption at any level of this complex relation can be underlying cause for many diseases. Both intestinal bacterial population and their metabolic products are involved in immune system development, activity and maintenance of immune homeostasis. Previous findings revealed differences in immune reactivity in Albino Oxford (AO) and Dark Agouti (DA) rat strains in various diseases models (such as experimental autoimmune encephalomyelitis, rheumatoid arthritis, contact hypersensitivity reaction, pulmonary aspergillosis etc.), and in response to xenobiotics such as cadmium, warfarin, etc.
The aim of present study was to investigate microbial composition of gut (duodenum, jejunum, coecum and colon) and lungs of AO and DA rats using DGGE method. Although similar number of bacterial species were noted in both tissue and lumen of duodenum, bacterial composition differ between these two strains (solely 76.2% and 44.4% species were common in both strains tissue and lumen, respectively), while greater variability was noted in DA rats. Similar results were noted in jejunum. In contrast to duodenum and jejunum, higher number of bacterial species were detected in coecum (content) and colon (tissue and content) of AO rats. Around 50% of detected bacteria were present in both gut segments of both strains. Analysis of DGGE bands obtained from lung tissue revealed similar number of bacteria in both strains, but solely 54.5% were common. Further investigations will be directed to identification of bacterial species and try to connect observed differences in microbial composition with different immune reactivity in AO and DA rats.

AB  - Microbiota inhabiting mucosal tissues is involved in maintenance of their immune homeostasis. Growing body of evidence indicate that dysbiosis in gut influence immune responses at distal sites including lungs. There are also reports concerning gut involvement with pulmonary injury/inflammation in settings of respiratory viral and bacterial infections. The impact of infections with other microorganisms on gut homeostasis is not explored. In this study, the rat model of sublethal pulmonary infection with Aspergillus fumigatus was used to investigate the effect of fungal respiratory infection on gut immune-mediated homeostasis. Signs of intestinal damage, intestinal and gut-draining lymphoid tissue cytokine responses and gut bacterial microbiota diversity were examined. Intestinal injury, inflammatory cell infiltration, as well as increased levels of intestinal interferon-γ (IFN-γ) and interleukin-17 (IL-17) (as opposed to unchanged levels of anti-inflammatory cytokine IL-10) during the two-week period depict intestinal inflammation in rats with pulmonary A. fumigatus infection. It could not be ascribed to the fungus as it was not detected in the intestine of infected rats. Increased production of pro-inflammatory cytokines by major gut-draining mesenteric lymph nodes point to these lymphoid organs as places of generation of cytokine-producing cells. No changes in spleen or systemic cytokine responses was observed, showing lack of the effects of pulmonary A. fumigatus infection outside mucosal immune system. Drop of intestinal bacterial microbiota diversity (disappearance of several bacterial bands) was noted early in infection with normalization starting from day seven. From day three, appearance of new bacterial bands (unique to infected individuals, not present in controls) was seen, and some of them are pathogens. Alterations in intestinal bacterial community might have affected intestinal immune tolerance contributing to inflammation. Disruption of gut homeostasis during pulmonary infection might render gastrointestinal tract more susceptible to variety of physiological and pathological stimuli. Data which showed for the first time gut involvement with pulmonary infection with A. fumigatus provide the baseline for future studies of the impact of fungal lung infections to gut homeostasis, particularly in individuals susceptible to these infections.

AB  - Albino Oxford (AO) rats are extremely resistant to induction of experimental autoimmune encephalomyelitis (EAE). EAE is an animal model of multiple sclerosis, a chronic inflammatory disease of the central nervous system (CNS), with established autoimmune pathogenesis. The autoimmune response against the antigens of the CNS is initiated in the peripheral lymphoid tissues after immunization of AO rats with CNS antigens. Subsequently, limited infiltration of the CNS occurs, yet without clinical sequels. It has recently become increasingly appreciated that gut-associated lymphoid tissues (GALT) and gut microbiota play an important role in regulation and propagation of encephalitogenic immune response. Therefore, modulation of AO gut microbiota by antibiotics was performed in this study. The treatment altered composition of gut microbiota in AO rats and led to a reduction in the proportion of regulatory T cells in Peyer's patches, mesenteric lymph nodes, and in lymph nodes draining the site of immunization. Upregulation of interferon-γ and interleukin (IL)-17 production was observed in the draining lymph nodes. The treatment led to clinically manifested EAE in AO rats with more numerous infiltrates and higher production of IL-17 observed in the CNS. Importantly, transfer of AO gut microbiota into EAE-prone Dark Agouti rats ameliorated the disease. These results clearly imply that gut microbiota is an important factor in AO rat resistance to EAE and that gut microbiota transfer is an efficacious way to treat CNS autoimmunity. These findings also support the idea that gut microbiota modulation has a potential as a future treatment of multiple sclerosis.

AB  - The aim of this study was to assess the effect of the probiotic Lactobacillus paraplantarum BGCG11 on the regulatory pathways that underlie the defense responses of the liver and kidney in diabetic rats. Probiotic-treated diabetic rats exhibited decreased hyperglycemia, glycated hemoglobin, triacylglycerols and a reduction in advanced glycation end products of serum proteins. The probiotic treatment adjusted the redox imbalance in the liver and kidney of diabetic rats, reduced the level of DNA damage, increased the activity of the pro-survival Akt kinase, decreased procaspase 3 degradation and lowered the level of inflammatory mediator C/EBPβ. Administration of probiotic to diabetic rats attenuated fibrotic process activated in the liver and kidneys as judged by the increase in E-cadherin and decreases in α-smooth muscle actin and fibronectin. In summary, the probiotic administration had an ameliorating effect on diabetes-associated disturbed redox homeostasis, inflammation and fibrosis, which underline the development of diabetic complications.

AB  - Gut microbiota and gut-associated lymphoid tissue have been increasingly appreciated as important players in pathogenesis of various autoimmune diseases, including multiple sclerosis. Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis that can be induced with an injection of spinal cord homogenate emulsified in complete Freund's adjuvant in Dark Agouti (DA) rats, but not in Albino Oxford (AO) rats. In this study, mesenteric lymph nodes (MLN), Peyer's patches (PP) and gut microbiota were analysed in these two rat strains. There was higher proportion of CD4(+) T cells and regulatory T cells in non-immunised DA rats in comparison to AO rats. Also, DA rat MLN and PP cells were higher producers of pro-inflammatory cytokines interferon-γ and interleukin-17. Finally, microbial analyses showed that uncultivated species of Turicibacter and Atopostipes genus were exclusively present in AO rats, in faeces and intestinal tissue, respectively. Thus, it is clear that in comparison of an EAE-susceptible with an EAE-resistant strain of rats, various discrepancies at the level of gut associated lymphoid tissue, as well as at the level of gut microbiota can be observed. Future studies should determine if the differences have functional significance for EAE pathogenesis.

AB  - Multiple sclerosis is a chronic inflammatory disease of the central nervous system (CNS). It is widely accepted that autoimmune response against the antigens of the CNS is the essential pathogenic force in the disease. It has recently become increasingly appreciated that activated encephalitogenic cells tend to migrate toward gut associated lymphoid tissues (GALTs) and that interrupted balance between regulatory and inflammatory immunity within the GALT might have decisive role in the initiation and propagation of the CNS autoimmunity. Gut microbiota composition and function has the major impact on the balance in the GALT. Thus, our aim was to perform analyses of gut microbiota in experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. Albino Oxford (AO) rats that are highly resistant to EAE induction and Dark Agouti (DA) rats that develop EAE after mild immunization were compared for gut microbiota composition in different phases after EAE induction. Microbial analyses of the genus Lactobacillus and related lactic acid bacteria showed higher diversity of Lactobacillus spp. in EAE-resistant AO rats, while some members of Firmicutes and Proteobacteria (Undibacterium oligocarboniphilum) were detected only in feces of DA rats at the peak of the disease (between 13 and 16 days after induction). Interestingly, in contrast to our previous study where Turicibacter sp. was found exclusively in non-immunized AO, but not in DA rats, in this study it was detected in DA rats that remained healthy 16 days after induction, as well as in four of 12 DA rats at the peak of the disease. Similar observation was obtained for the members of Lachnospiraceae. Further, production of a typical regulatory cytokine interleukin-10 was compared in GALT cells of AO and DA rats, and higher production was observed in DA rats. Our data contribute to the idea that gut microbiota and GALT considerably influence multiple sclerosis pathogenesis.
