Mitigation of avian reproductive tract function by Salmonella enteritidis producing high-molecular-mass lipopolysaccharide.

Abstract excerpt

Hens were infected with a wild-type Salmonella enteritidis and its wzz mutant, which lacked the ability to make high-molecular-mass lipopolysaccharide (LPS), in six experiments paired by dosage and route of exposure. Involution of the reproductive tract occurred in 86% of hens that were injected subcutaneously with 108 cfu of the wild-type strain, but none did so when injected with the wzz mutant. In spite of the...
