In order to control paratyphoid infections having a high zoonotic risk and involving significant economic damage, a National Control Programme for mobile Salmonella infections in breeding hens, including relevant serovars represented by S. enteritidis, S. infantis, S. hadar, S. typhimurium and S. virchow, has been implemented in Romania. During 2009-2012, an epidemiological study was conducted based on primary data collected from breeding hen holdings. Samples represented by faeces were taken at a frequency established by the Community legislation while the programme aims at obtaining a prevalence of 1% or less of the flocks with 95% confidence limit for breeding hens. Following the study, 149 strains belonging to the species Salmonella enterica subsp. enterica were isolated. The results obtained show that serotyped mobile Salmonella strains classified serologically into 16 serovars circulated within the breeding hen holdings. 19% of the isolated serovars belonged to S. enteritidis, 5% belonged to S. ifantis, 2.6% belonged to S. typhimurium while the incidence of other serovars was much lower.
