Abstract

 Pullorum disease, caused by SALMONELLA PULLORUM, is one of the most important SALMONELLA infections in poultry, involving primarily the chicks and poults. In this study, six, groups of ten 5-day-old quail chicks were orally inoculated with 0.2 in of selected concentrations (103-108 CFU/m1) of the bacterium. Eighty percent of the chicks died at the highest concentration. Also to determine the possibility of the natural infection, 20 one-day-old quail chicks were brought into content with a seeder for 3 weeks. In this experiment two birds died. The affected birds showed clinical signs similar to those of chicks and poults the main lesions observed were congestion and small white necrotic foci in liver, enlargement of spleen, pericarditis, cardiac and pulmonary nodules and cecal core. Also kidneys were sometimes congested or anemic with an accumulation of urates in ureters. Viable bacteria were cultured from the liver, spleen, lungs, heart, pancreas, kidneys and ceca. It is concluded that quail chicks are suscep-to S.pullorum and there is a chance of spread of the infection from quail to chickens.
