Reptiles are considered a reservoir of a variety of Salmonella (S.) serovars. Nevertheless, due to a lack of large-scale research, the importance of Reptilia as a Salmonella vector still remains not completely recognized. A total of 731 samples collected from reptiles and their environment were tested. The aim of the study was to assess the prevalence of Salmonella in exotic reptiles kept in Poland and to confirm Salmonella contamination of the environment after reptile exhibitions. The study included Salmonella isolation and identification, followed by epidemiological analysis of the antimicrobial resistance of the isolates. Implementation of a pathway additional to the standard Salmonella isolation protocol led to a 21% increase in the Salmonella serovars detection rate. The study showed a high occurrence of Salmonella, being the highest at 92.2% in snakes, followed by lizards (83.7%) and turtles (60.0%). The pathogen was also found in 81.2% of swabs taken from table and floor surfaces after reptile exhibitions and in two out of three egg samples. A total of 918 Salmonella strains belonging to 207 serovars and serological variants were obtained. We have noted the serovars considered important with respect to public health, i.e., S. Enteritidis, S. Typhimurium, and S. Kentucky. The study proves that exotic reptiles in Poland are a relevant reservoir of Salmonella.

Over Time

In this 1-year survey from October 2006 to September 2007, we isolated and characterized 126 Salmonella isolates from conventionally raised (n = 141) and organically raised (n = 53) chicken carcasses obtained from 27 retail stores in Baton Rouge, Louisiana. Salmonella was isolated from 22% of conventional and from 20.8% of organic chicken samples. Eight Salmonella serovars were identified; predominant ones included Kentucky, Hadar, and Enteritidis. The vast majority of isolates within the same chicken sample possessed the same pulsed-field gel pattern. All Salmonella isolates were susceptible to amikacin, ceftriaxone, and ciprofloxacin; however, decreased susceptibility to quinolones (7.1%) or extended-spectrum cephalosporins (45.2%) was observed. Resistance to multiple antimicrobials (two or more) was found among 52.4% of the Salmonella isolates. Antimicrobial resistance profiles differed greatly among Salmonella serovars and also depended on the type of chicken from which they were recovered. Salmonella Kentucky isolates from organic chicken samples were susceptible to 11 of the antimicrobials tested, whereas those from conventional chickens were only susceptible to 4 antimicrobials. Three Salmonella Kentucky isolates from conventional chickens possessed multidrug resistance phenotype MDR-AmpC. Results of this study provide baseline data on both prevalence and antimicrobial resistance of Salmonella in retail chickens in this region and emphasize the need for implementing effective control measures to reduce Salmonella contamination and the levels of antimicrobial-resistant Salmonella in both conventionally and organically raised poultry products. Further studies involving larger sample sizes over time are needed to better monitor and assess the trend of prevalence and antimicrobial susceptibility among Salmonella serovars in retail chickens.

This study was undertaken to determine the prevalence and distribution of Salmonella on 57 randomly selected broiler farms at the end of the rearing period and in chicken products in urban and periurban areas in Casamance, Senegal, and to evaluate the antimicrobial resistance profiles of the Salmonella serovars. Salmonella was detected in chicken feces, on carcass skin, and in muscle on 35.1, 38.6, and 29.8% of farms, respectively. Salmonella was found in chicken meat servings from 14.3% of the 42 street restaurants and in 40.4% of the 285 chicken carcasses examined. The prevalence on skin and in muscle was significantly associated with the detection of Salmonella in feces (P ≤ 0.001). Eighteen Salmonella serovars were identified; the most common were Brancaster (57.9%), Goelzau (10.7%), Kentucky (8.4%), and Hadar (7.3%). High levels of resistance were found to trimethoprim-sulfamethoxazole, tetracycline, trimethoprim, streptomycin, and sulfonamides. All Salmonella serovars were susceptible to fluoroquinolones and third-generation cephalosporins. A large proportion of the isolates belonging to 11 serovars were resistant to two or more antibiotics. Salmonella continues to be of serious concern in the broiler production chain in Senegal.

ABSTRACT Retail organic (n = 198) and conventional (n = 61) chickens were analyzed. Most organic (76%) and conventional (74%) chickens were contaminated with campylobacters. Salmonellae were recovered from 61% of organic and 44% of conventional chickens. All Salmonella enterica serovar Typhimurium isolates from conventional chickens were resistant to five or more antimicrobials, whereas most S. enterica serovar Typhimurium isolates (79%) from organic chickens were susceptible to 17 antimicrobials tested.
