a
Results expressed as the number of chicks that were Salmonella colonized in their ovaries-oviducts/total number of chicks analyzed for each isolate.
b
Results expressed as the proportion of Salmonella-positive animals from the total number of animals tested for each isolate.
c
Isolates showing significant difference of spleen invasiveness compared to that of PT4.
d
Animals shown in Fig. 4 were analyzed for the presence of Salmonella in enriched homogenates of ovaries-oviducts.
