“…This particular species appeared to be mostly absent in the Il10 -/-mice. This suggests that this species could belong to the resident murine microflora in control mice, as observed in the stools of healthy subjects (Ceelen et al, 2006). As it has been shown that Helicobacter spp.…”

Diversity of caecal bacteria is altered in interleukin-10 gene-deficient mice before and after colitis onset and when fed polyunsaturated fatty acids

Interleukin-10 gene-deficient (Il10 –/–) mice show a hyper-reaction to normal intestinal bacteria and develop spontaneous colitis similar to that of human Crohn's disease when raised under conventional (but not germ-free) conditions. The lack of IL10 protein in these mice leads to changes in intestinal metabolic and signalling processes. The first aim of this study was to identify changes in the bacterial community of the caeca at 7 weeks of age (preclinical colitis) and at 12 weeks of age (when clinical signs of colitis are present), and establish if there were any changes that could be associated with the mouse genotype. We have previously shown that dietary n-3 and n-6 polyunsaturated fatty acids (PUFA) have anti-inflammatory effects and affect colonic gene expression profiles in Il10 –/– mice; therefore, we also aimed to test the effect of the n-3 PUFA eicosapentaenoic acid (EPA) and the n-6 PUFA arachidonic acid (AA) on the bacterial community of caeca in both Il10 –/– and C57 mice fed these diets. The lower number of caecal bacteria observed before colitis (7 weeks of age) in Il10 –/– compared to C57 mice suggests differences in the intestinal bacteria that might be associated with the genotype, and this could contribute to the development of colitis in this mouse model. The number and diversity of caecal bacteria increased after the onset of colitis (12 weeks of age). The increase in caecal Escherichia coli numbers in both inflamed Il10 –/– and healthy C57 mice might be attributed to the dietary PUFA (especially dietary AA), and thus not be a cause of colitis development. A possible protective effect of E. coli mediated by PUFA supplementation and associated changes in the bacterial environment could be a subject for further investigation to define the mode of action of PUFA in colitis.

“…Helicobacter pullorum is a gram-negative species, slightly curved rod with monopolar, nonsheathed flagella, classified in ureas-negative enterohepatic group of Helicobacters [1] which naturally colonize the gastrointestinal tract surface [2] . H. pullorum has been linked with enteritis and hepatitis in broiler chickens and laying hens, and diarrhea, gastroenteritis, and liver disease in humans [1] .…”

For evaluation of pet birds as a resource of Helicobacter pullorum, 100 cecal content samples were collected from 50 finches and 50 Australian parrots, with no clinical signs suggestive of systemic and/or enteric disease, in Iran. DNA was extracted from cecal samples and PCR was carry out for identification of H. pullorum 16S rRNA gene. Results showed, H. pullorum DNA was detected in 3 of the 50 (6%) cecal samples of finch and 6 out of 50 (12%) cecal samples of Australian parrot. This study represents that finch and Australian parrot can be a source of H. pullorum infection and serve as reservoirs for the H. pullorum.

Sekal örneklerden DNA ekstraksiyonu yapıldı ve H. pullorum 16S rRNA geninin identifikasyonu amacıyla PCR gerçekleştirildi. H. pullorum geni 50 ispinozun 3'ünde (%6) ve 50 Avustralya papağanının 6'sında (%12) belirlendi. Çalışmanın sonuçları ispinoz ve Avustralya papağanının H. pullorum enfeksiyonu kaynağı ve bu etken için reservuar olabileceğini göstermiştir.
