“…Our findings show that S. Derby is the most often isolated serotypes in poultry. This is in contrast with results reported by some authors, showing that this serotype is most common in pig and also the 4 most frequently isolated serotype in humans in Europe (Kerouanton et al, 2013;Hauser et al, 2011).…”

“…However, information on the diversity and occurrence of Salmonella strains is very scarce (Cui et al, 2008), making the ecology of these species remains unknown. Food animals, including poultry, pigs, and cattle are the key reservoirs for human salmonellosis (Hauser et al, 2011). In developing countries, wild and food animals are the sources of Salmonella distribution in water, vegetables, salad and the products derived from these animals due to lack of hygiene (Kagambèga et al, 2013).…”

Epidemiologic and traceback evidence of Salmonella infection is not much in many developing countries including Burkina Faso. This study investigates the antimicrobial resistance and distribution of Salmonella serotypes isolated from diverse sources in Burkina Faso. 615 Salmonella serotypes isolated from beef meat, poultry carcasses, poultry, swine, cattle, hedgehog, fish, salad, channel and humans from 2009 to 2011 were analyzed to identify their diversity and distribution among the samples. The Salmonella strains were subjected to antimicrobial sensitivity tests using disk diffusion methods, were analyzed and classified into 110 serotypes, with the most prevalent serotype being Derby (91/615) found in beef meat, poultry carcasses, poultry and fish; Muenster (48/615) found in cattle, swine, hedgehog, poultry, human and fish; Chester (38/615) found in poultry carcasses, swine and poultry feces; Hato (32/615) found in beef meat, poultry carcasses, cattle and poultry; Drac (30/615) found in cattle, hedgehog and fish; and Typhimurium (21/615) found in cattle, poultry, human and fish. Among the 615 Salmonella strains, 94% (581/615) were resistant to one or more antibiotics; resistance to streptomycin was the most common. The resistance pattern, Str-Sul-Tet, Str-Tet and Str-Sul was dominant and found in 80% of the strains. About 3% of the strains were resistant to 5 or 6 antibiotics; their resistance pattern is amp-str-sul-tet-tmp or amp-chl-str-sul-tet-tmp. One Salmonella strain, S. Kentucky isolated from human stool was resistant to eight antibiotics; the resistance pattern is amp-strsul-tet-cip-gen-nal-mec. Findings from this study can help define the guidelines for basic surveillance system of Salmonella and other enteropathogenic bacteria circulating among humans, animals, food and environment.

Introduction: The aim of this study was to determine the prevalence of Salmonella along the slaughter line and to identify possible critical control points in one slaughterhouse facility located in the city of Belgrade. Methodology: In total, 700 samples were tested: two swabs from both sides of carcass were taken from each of 100 pigs. In this way, 200 pig skin swab samples were taken after stunning, 200 after processing and 200 after chilling. Additional 100 samples of ileal contents were also taken from the same pigs to obtain a collection of 270 isolates. All samples were analyzed using standard culture methods and serotyping. PFGE was performed for 27 isolates. Determination of antimicrobial resistance was performed by E-test. Results: In total, 47 (23.5%) swab samples were positive for the presence of Salmonella after stunning. After processing, Salmonella was isolated in two swab samples (1%), whereas all samples which were collected after chilling were negative for Salmonella. The sampling of ileal contents was positive for five Salmonella isolates (5%). The most frequently isolated serotypes were S. Derby (90.74%), S. Infantis (5.56%) and S. Typhimurium (3.7%). All tested isolates were resistant to tetracycline. Resistance was recorded to nalidixic acid (23.3%), ciprofloxacin (20%), ampicillin (10%) and chloramphenicol (14.4%), as well. The PFGE results indicated that isolates had a high genetic similarity. Conclusions: The investigation has confirmed that bacteriological examinations of carcass swabs, as well as ileal content, could be used to assess the carriage of salmonellae in pigs at the time of slaughter.

In this study, the population structure, incidence, and potential sources of human infection caused by the D-tartrate-fermenting variant of Salmonella enterica serovar Paratyphi B [S. Paratyphi B (DT؉)] was investigated. In Germany, the serovar is frequently isolated from broilers. Therefore, a selection of 108 epidemiologically unrelated S. enterica serovar Paratyphi B (DT؉) strains isolated in Germany between 2002 and 2010 especially from humans, poultry/poultry meat, and reptiles was investigated by phenotypic and genotypic methods. Strains isolated from poultry and products thereof were strongly associated with multilocus sequence type ST28 and showed antimicrobial multiresistance profiles. Pulsed-field gel electrophoresis XbaI profiles were highly homogeneous, with only a few minor XbaI profile variants. All strains isolated from reptiles, except one, were strongly associated with ST88, another distantly related type. Most of the strains were susceptible to antimicrobial agents, and XbaI profiles were heterogeneous. Strains isolated from humans yielded seven sequence types (STs) clustering in three distantly related lineages. The first lineage, comprising five STs, represented mainly strains belonging to ST43 and ST149. The other two lineages were represented only by one ST each, ST28 and ST88. The relatedness of strains based on the pathogenicity gene repertoire (102 markers tested) was mostly in agreement with the multilocus sequence type. Because ST28 was frequently isolated from poultry but rarely in humans over the 9-year period investigated, overall, this study indicates that in Germany S. enterica serovar Paratyphi B (DT؉) poses a health risk preferentially by contact with reptiles and, to a less extent, by exposure to poultry or poultry meat.
