Summary of "Rat H1 parvovirus infection leads to alterations in gut microbiota."

H1 parvovirus (H1PV) infection in rats is of concern to the research community as infection may compromise rodent-based experiments. The aim of this study was to evaluate the influence of H1PV infection on rat gut microbiota. Inbred Wistar rats were infected with H1PV by routine gavage and clinical signs were recorded. Gross anatomical and histopathological examination of the gut was performed, as was immune cytokine analysis. The cecal contents were also collected for 16 s rRNA sequencing. Gross anatomical examination showed distention of the ileum associated with flatulence after infection, while histopathological examination showed hyperemia and inflammatory cell infiltration in the ileum. Upregulation of the interleukin-6 in sera in H1PV infected rats was also detected. The gut microbiota had been significantly changed in H1PV infected rats: there was a reduction in several bacteria species including probiotic bacteria from the genera Parabacteroides and Butyricicoccus, while others were increased, including those from the genera Methanobrevibacter and Syntrophococcus. Taken together these results demonstrate that chronic H1PV infection in rats leads to gastrointestinal inflammation with flatulence. The gut microbiota alterations were associated with decreased polymorphisms, reduced abundance of probiotic bacteria and increased abundance of methane producing bacteria.

Medical and Biotech [MESH] Definitions

A species of PARVOVIRUS infecting cats with a highly contagious enteric disease. Host range variants include mink enteritis virus, canine parvovirus (PARVOVIRUS, CANINE), and raccoon parvovirus. After infecting their new hosts, many of these viruses have further evolved and are now considered distinct species.

A highly contagious parvovirus infection in mink, caused by MINK ENTERITIS VIRUS or the closely related FELINE PANLEUKOPENIA VIRUS or CANINE PARVOVIRUS. Transmission usually occurs by the fecal/oral route.
