Zakażenia pałeczkami Salmonella są powszechne wśród ludzi i zwierząt, występują na całym świecie, zarówno w krajach wysoko rozwiniętych, cechujących się znacznym poziomem higieny, jak i w krajach ubogich, z niedostateczna opieką zdrowotną. Z tych przyczyn salmoneloza jest nadal poważnym zagrożeniem dla zdrowia człowieka. Problem ten może okresowo urastać nawet do rangi politycznej, jak np. w przypadku wybuchu epidemii.

Many Salmonella Enteritidis virulence factors are encoded by genes localized on plasmids, especially large virulence plasmid, in highly conserved fragment, they create spv plasmid gene group. The aims of realized researches were spv genes occurrence evaluation and composition analysis among Salmonella Enteritidis strains caused infection in chickens. Researches were realized on 107 isolates, where in every cases large virulence plasmid 59 kbp size were detected. Specific nucleotides sequences of spv genes (spvRABCD) were detected in 47,7% of isolates. In the rest of examinated bacterias spv genes occurred variably. Most often extreme genes of spv group, like spvR and spvD were absent, what could indicate that factors encoded by them are not most important for Salmonella Enteritidis live and their expressed virulence.
