“…Antibiotic resistance profiles were employed in many previous studies as a typing method for several Salmonella serotypes (Moore et al, 2003). In this report, we found that antibiogram typing is not a very useful tool for subtyping S. enteritidis strains, because the majority of isolates were susceptible to all antibiotic tested.…”

-Salmonella enterica serovar Enteritidis is one of the major Salmonella serovars which may cause animal infections and human salmonellosis. In this study, two hundred forty five samples (faeces, water and environmental swabs) were taken from eight poultry farms localized in different geographical areas of Tunisia. We found Salmonella serovar Enteritidis (16 strains), Salmonella typhimirium (2), Salmonella scharzengrund (2), and Salmonella braenderup (1). Salmonella Enteritidis strains were characterized by pulsed field gel electrophoresis (PFGE) analysis, plasmid analysis and antibiotic resistance profiles. XbaI PFGE analysis revealed two PFGE types and plasmid profiling identified four plasmid types. The majority of isolates were susceptible to all antibiotic tested. The combined use of phenotypic and genotypic methods indicates the spread of a particular Salmonella Enteritidis clone. This clone is highly related to a major world-wide clone identified in many other countries.

“…Bacteraemia is associated with a secondary focal infection, especially endovascular infection, with up to 25 % of patients over the age of 50 developing this complication. S. bredeney is a rare, non-typhoidal Salmonella that has only occasionally been reported in outbreaks (Jahraus & Philips, 1999;Moore et al, 2003).…”

“…S. Typhimurium ranked 6 th in fattening turkey flocks in 2006/7, whereas S. Bredeney was the most common serovar in turkeys (17.2 % positive flocks) albeit in only six countries, but S. Bredeney is not a common isolate from human cases. It has been identified only rarely in human outbreaks but is predominantly associated with chicken meat (Baker et al, 1998;Moore et al, 2003). S. Hadar was found in 14.0 % of fattening flocks in ten countries.…”

The quantitative contribution of turkeys and other major animal‐food sources to the burden of human salmonellosis in the European Union was estimated. A ‘Turkey Target Salmonella Attribution Model’ (TT‐SAM) based on the microbial‐subtyping approach was used. TT‐SAM includes data from 25 EU Member States, four animal‐food sources of Salmonella and 23 Salmonella serovars. The model employs 2010 EU statutory monitoring data on Salmonella in animal populations (EU baseline survey data for pigs), data on reported cases of human salmonellosis and food availability data. It estimates that 2.6 %, 10.6 %, 17.0 % and 56.8 % of the human salmonellosis cases are attributable to turkeys, broilers, laying hens (eggs) and pigs, respectively. The top‐6 serovars of fattening turkeys that contribute most to human cases are S. Enteritidis, S. Kentucky, S. Typhimurium, S. Newport, S. Virchow and S. Saintpaul. Comparing the prevalence of Salmonella in turkey flocks reported in 2010 with a theoretical combined prevalence for S. Enteritidis and S. Typhimurium of 1 % (i.e. the transitional target), a reduction of 0.4 % in the percentage of turkey‐associated human salmonellosis cases would be achieved. However, when adjusting the combined prevalence of all serovars to 1 %, an 83.2 % reduction in the percentage of turkey‐associated human salmonellosis cases, equivalent to 2.2 % of all human salmonellosis cases, is expected. Uncertainty and data limitations are discussed, including recommendations on how these could be overcome. Vertical transmission of Salmonella as well as hatchery acquired Salmonella contamination originating from breeding stock are very important sources for Salmonella infection in turkeys, and therefore controlling Salmonella in breeding flocks as well as in rearing and fattening flocks is necessary to minimise Salmonella in turkeys at slaughter.
