摘要

This study determined the prevalence of Salmonella serovars, antimicrobial resistance (AMR) and resistance genes in Salmonella isolated from retail meats purchased in Alberta, Canada. Samples were collected during one year period (May 2007-April 2008) on weekly basis from 19 census divisions in Alberta. A total of 564 samples including chicken (n = 206), turkey (n = 91), beef (n = 134) and pork (n = 133) were purchased. Salmonella were recovered from chicken (40%), turkey (27%) and pork (2%) samples and was not found in ground beef. A total of 21, 8, and 3 different serovars were recovered from chicken, turkey and pork meats, respectively. Salmonella Hadar was most common in chicken whereas S. Heidelberg was common in turkey meat. Overall 29% (32/110) of isolates were susceptible to tested antimicrobials and resistance to ciprofloxacin, amikacin and nalidixic acid was not found in any isolate. Multiresistance (≥2 antimicrobials) was found in 56% of isolates. Resistance to amoxicillin-clavulanic acid (AMC), ceftiofur (TIO), and ceftriaxone (CRO) was found in about 21% of chicken and 25% of turkey isolates. Resistance to either of tetracycline (TET), streptomycin (STR) or ampicillin (AMP) was unconditionally associated with S. Hadar but resistance to either of TET, AMP, AMC, TIO, CRO or cefoxitin was associated with S. Heidelberg. The strA/B (42% isolates), tet(A) (28% isolates), bla_(CMV-2) (21% isolates) and bla_(TEM) (17% isolates) were the most common resistance genes found. The bla_(CMY-2) and bla_(TEM) genes were unconditionally associated with S. Heidelberg; tet(A) and strA/B with S. Hadar and tet(B) gene with S. Kentucky. The strA/B genes were not associated with S. Heidelberg. Our data suggests that the prevalence of Salmonella serovars varied by the meat type and that AMR and resistance genes varied by the Salmonella serovars.

Heidelberg在火鸡肉中很常见。总体上有29％（32/110）的分离株易受测试的抗生素的影响，在任何分离株中均未发现对环丙沙星，丁胺卡那霉素和萘啶酸的耐药性。在56％的分离物中发现了多药耐药性（≥2种抗菌药物）。在约21％的鸡肉和25％的火鸡分离物中发现了对阿莫西林-克拉维酸（AMC），头孢噻呋（TIO）和头孢曲松（CRO）的耐药性。对四环素（TET），链霉素（STR）或氨苄青霉素（AMP）的抗性与S. Hadar无条件相关，但对TET，AMP，AMC，TIO，CRO或头孢西丁的抗性与S. Heidelberg相关。发现的最常见抗性基因为strA / B（42％分离株），tet（A）（28％分离株），bla_（CMV-2）（21％分离株）和bla_（TEM）（17％分离株）。 bla_（CMY-2）和bla_（TEM）基因与S. Heidelberg无条件相关。带有S. Hadar的tet（A）和strA / B和带有S.Kentucky的tet（B）基因。 strA / B基因与海德堡链菌无关。我们的数据表明沙门氏菌血清型的患病率随肉类类型而异，而AMR和耐药基因随沙门氏菌血清型而变化。
