Influence of Salmonella enterica serovar Enteritidis infection on the composition of chicken cecal microbiota.

ABSTRACT:

Background

Infection of newly hatched chicks with Salmonella enterica serovar Enteritidis (S. Enteritidis) results in an inflammatory response in the intestinal tract which may influence the composition of gut microbiota. In this study we were therefore interested whether S. Enteritidis induced inflammation results in changes in the cecal microbiota. To reach this aim, we compared the cecal microbiota of non-infected chickens and those infected by S. Enteritidis by pyrosequencing the V3/V4 variable regions of genes coding for 16S rRNA.

Results

Cecal microbiota of chickens up to 19 days of life was dominated by representatives of Enterobacteriaceae, Lachnospiraceae and Ruminococcaceae, followed by Lactobacillaceae. The presence of Lachnospiraceae did not change after S. Enter
