| Abstract | ||
| Two rarely isolated Salmonella serovars, Salmonella Teshie (belonged to Arizona group) and Salmonella Ferruch were examined for selected virulence factors which may be operative in studied serOVars including pathogenesis in mice, Congo red binding ability. Production of heat-stable enterotoxin, cytotoxin, haemolysin and antibacterial resistance. The obtained results indicated that oral inoculation of mice with both serovarS showed distribution of Salmonella in their different interAl organs at different intervals ranging from, 3 Rs up to 9 days post inoculation associated with Istopathological changes. Both serovars had Congo red binding activity. S. Ferruch but not S. Lestiie produced heat-stable enterotoxin, Both sErovars were not cytotoxic to Vero cells. MoreovEr, both serovars produced (-haemolysin, and D multiple antibacterial resistance. | ||
