Description
Summary:Contamination of ISA BROWN layer hens by Salmonella spp. and serotyping of the isolated strains were performed in 30 farms. Salmonella detection was done from feces and cloaca swabs. Eggs produced in the farms contaminated by Salmonella spp. were analyzed by culturing the shell rinsing and egg yolk. Salmonella spp. was isolated in eight (23.0%) farms, but was not detected from eggs. S. Enteritidis, which is the most prevalent sorotype associated to human salmonelosis in Parana State, was not isolated either from birds or eggs analyzed. The sorotypes isolated were Salmonella enterica subsp. enterica (0:3.10) (67.0%), Mbandaka (11.0%), Infantis (11.0%), and Newport (11.0%).
