Survival in water of XXXX strains isolated from the slaughterhouse.

@entity1 @entity1902 @entity1573 @entity5363 @entity4202
@entity5363 cause @entity1902 in @entity1 . The main transmission vector is the consumption or handling of contaminated @entity1573 meat, since @entity1573 can be colonized asymptomatically by @entity5363 . However, water has been implicated as the transmission vector in a few outbreaks. One possibility is the contamination of water effluent by @entity5363 originating from @entity1573 farm. The ability of @entity5363 to be transmitted by water would be closely associated to its ability to survive in water. Therefore, in this study, we have evaluated the ability of reference strains and @entity1573 -isolated strains to survive in water. Defined water media were used, since the composition of tap water is variable. We showed that some isolates survive better than others in defined freshwater (Fraquil) and that the survival was affected by temperature and the concentration of @entity4202 . By comparing the ability of @entity5363 to survive in water with other phenotypic properties previously tested, we showed that the ability to survive in water was negatively correlated with autoagglutination. Our data showed that not all @entity1573 isolates have the same ability to survive in water, which is probably due to difference in genetic content.
