Abstract

In order to evaluate the invasive capacity of Salmonella enterica sorovar Enteritidis phagotipe 4 of avian origin, in two broiler lines, two experiments were carried out. The experiment 1 was done with Ross line (fast growing rate) and experiment 2 was done with ISA Label (slow growing rate). In two experiments the same 1.5 X 102 UFC/0,1mL de Salmonella Enteritidis phagotipe 4 was inoculated in egg through the eggshell or albume at the incubation to averiguate the clinical signs, the macro and microscopical lesions and mortality rate until three weeks of age. The Salmonella Enteritidis invaded and colonizated the gastrointestinal tract of the two lines tested general clinical signs allied to intestinal disfunction were more pronounced in Ross broilers. The mortality observed was 25.0% (15/60) in Ross and just 1.7% (1/60) ISA Label broilers during three weeks. Onphalitis, enteritis, pericarditis, perihepatitis constituted the main macroscopic lesions in Ross. At histological exam, inflamatory process observed with infiltrates of mononuclear cells with predominance of macrophage and lymphocytes in heart, duodenum, jejunum, ileum, ceca and liver. It is possible to conclude the gastrointestinal tract, invaded organs of both genetic lines, but ISA Label was resistant to infection compared to Ross lines.
