“…We found the high levels of Salmonella contamination rate in chicken (63.6%) and pork (73.1%) collected from retail markets in Guangdong Province, China. These prevalences were significantly higher than those reported in similar studies in other districts in China, such as Hebei ( Yan et al, 2010 ), Sichuan ( Li et al, 2013 ), Henan ( Li et al, 2014 ), Beijing ( Wang et al, 2014 ), Jiangsu ( Bai et al, 2015 ), and Shandong ( Cui et al, 2016 ). Meanwhile, the Salmonella contamination rate was higher than that of other parts of Asia, such as South Korea ( Choi et al, 2015 ), Tokyo ( Katoh et al, 2015 ), and Northern Vietnam ( Thai et al, 2012 ), and higher than that reported in Egypt ( Gharieb et al, 2015 ).…”

This study aimed to investigate the prevalence, serotype distribution, and antibiotic resistance, and to characterize the extended spectrum β-lactamases (ESBLs) producing Salmonella isolates from chicken and pork meats from retail markets in Guangdong province, China. A total of 903 retail meat samples (475 chicken and 428 pork meats) were obtained from six cities (Guangzhou, Shenzhen, Heyuan, Shaoguan, Foshan, and Yunfu) of Guangdong province between May 2016 and April 2017. High levels of Salmonella contamination were detected in chicken (302/475, 63.6%) and pork (313/428, 73.1%). Thirty-eight serotypes were identified in 615 detected Salmonella, and the serotypes varied greatly between chicken and pork samples. Agona (55/302, 18.2%), Corvallis (45/302, 14.9%), Kentucky (38/302, 12.6%), Mbandaka (32/302, 10.6%) was the dominant serotypes in chicken samples. However, Typhimurium (78/313, 24.9%), Rissen (67/313, 24.1%), Derby (66/313, 21.1%), and London (48, 15.3%) were the most common in pork samples. High rates of antibiotic resistance were found to sulfisoxazole (468/615, 76.1%), tetracycline (463/615, 75.3%), ampicillin (295/615, 48.0%), and ofloxacin (275/615, 44.7%). Notably, antimicrobial susceptibility tests identified resistance to polymyxin B (12/615, 2.0%) and imipenem (3/615, 0.5%). Multidrug-resistance (MDR) was detected in Salmonella isolated from chicken (245/302, 81.1%) and pork (229/313, 73.2%). The resistance rate of different Salmonella serotypes varied widely. Especially, isolates such as Typhimurium, Agona, Corvallis and Kentucky exhibited highly resistance to antibiotics. The MDR rate of Salmonella isolates from chicken was significantly higher than that from pork isolates (P < 0.05). Twenty-one Salmonella isolates were identified as ESBLs-producing, covering six Salmonella serotypes and displaying different pulse field gel electrophoresis (PFGE) genotypes. BlaOXA-1 was the dominant ESBLs gene (9/21, 42.9%), followed by blaCTX-M-55 (5/21, 23.8%). This study indicated that Salmonella was widespread in chicken and pork from retail markets in Guangdong province and the isolates showed high multidrug-resistance, especially the known multidrug-resistant Salmonella serotypes. Therefore, it is important to focus on Salmonella serotypes and strengthen the long-term monitoring of MDR Salmonella serotypes in animal-derived foods.

“…isolated from chicken meat parts was highly resistant to NA (100%). Our findings are consistent with studies conducted in different countries (CUI et al, 2016;SODAGARI et al, 2015) and in Turkey (KASIMOGLU DOGRU et al, 2010;SIRIKEN et al, 2015). In the past, ampicillin, chloramphenicol and co-trimoxazole were used to treat salmonellosis, but they have been replaced by fluoroquinolone antibiotics, such as ciprofloxacin and cephalosporin.…”

Specific microbiological parameters and the presence of Salmonella spp. were investigated in 72 chicken meat samples (36 wings and 36 drumsticks) collected from markets and butcher shops. The specific microbiological parameters were determined using a conventional cultural method and the presence of Salmonella spp. in chicken samples was determined using conventional and immunomagnetic separation (IMS)-polymerase chain reaction (PCR) methods. In addition, antimicrobial susceptibility of the isolates was revealed using the Kirby-Bauer disc diffusion method. The results indicated that 30 of the 72 samples were positive for Salmonella spp. by the conventional method, and 42 of the 72 were positive by the IMS-PCR method. However, 30 of the 72 samples were positive for Salmonella spp. by both methods. The Salmonella spp. isolates were confirmed by the VITEK2 Compact System and PCR. The susceptibilities of the isolates against 10 antibiotics were determined. The results indicated that isolates (27/30) showed the highest susceptibility to gentamycin (90.00%), while the highest resistance was to nalidixic acid and tetracycline at the 100 and 93.34% levels, respectively. These results indicate a high prevalence of Salmonella spp. in poultry meat from Erzurum city, Turkey, and the antimicrobial resistance profile of these isolates should be considered for public health. The results also show that the IMS-PCR technique was superior to the conventional method for detecting Salmonella in poultry meat.

“…resultados de la presencia de Salmonella en las heces de pollos son similares a los reportados en Colombia en donde se detectó una prevalencia de 65% (n= 315) (Donado-Godoy et al 2012). Sin embargo, en China este microorganismo fue aislado del 11.4% (n=290) de muestras de ciegos y en España la prevalencia del patógeno en granjas de pollos de engorde fue del 1.02% (n=6577) (Cui et al 2016, Lamas et al 2016. En Estados Unidos Salmonella se detectó en el 43.1% (n=109) y 13.6% (n=220) de muestras de hisopado de barrido y heces, respectivamente (Berghaus et al 2013).…”

RESUMEN.-A nivel mundial Salmonella es la responsable de causar millones de casos de gastroenteritis humana y más de cien mil defunciones cada año. Una de las principales fuentes de contagio esta bacteria son los productos de origen aviar. La utilización generalizada de antimicrobianos en la industria avícola ha favorecido el surgimiento de cepas de Salmonella multirresistentes. Dichas cepas podrían transmitirse al ser humano a través del consumo de productos cárnicos contaminados. El objetivo de esta investigación fue identificar serotipos y patrones de resistencia antimicrobiana de cepas de Salmonella aisladas en una empresa avícola integrada en Ecuador. Al final del período de muestreo se recolectaron 289 muestras que fueron analizadas en base a la norma NTE INEN-ISO 6579 Anexo D. El 20.1% de las muestras fueron positivas a Salmonella, identificándose 4 diferentes serovariedades, siendo S. Infantis (74.1%) el serotipo más frecuente. La mayoría de cepas de Salmonella presentaron resistencia a nitrofurantoína (94.8 %), tetraciclina (82.8%), cloranfenicol (79.3%) y trimetopin-sulfametoxazol (81%). Los resultados de este estudio indican que Salmonella puede estar presente en los diferentes procesos de la industria avícola ecuatoriana, además la resistencia antibacteriana de cepas aisladas en carne de pollo puede representar un riesgo para la salud pública.

A major source of this bacteria are poultry products. The widespread use of antibiotics in poultry industry has favored the emergence of multidrug-resistant strains of Salmonella. Such strains could be transmitted to humans through consumption of contaminated meat products. The objective of this research was to identify serotypes and antimicrobial resistance patterns of Salmonella strains isolated from an integrated poultry company in Ecuador. A total of 289 samples were analyzed with the ISO 6579 Annex D protocol. The results showed 20.1% of positive samples. Four serotypes were found from which S. Infantis (86.2%) was the most frequent serotype. Most Salmonella strains were resistant to nitrofurantoin (94.8 %), tetracycline (82.8%), chloramphenicol (79.3%) and trimetopin-sulfamethoxazole (81%). The results shown in this study indicate that Salmonella may be present in different processes of Ecuador's poultry industry and that antibacterial resistance strains isolated from chicken meat may represent a risk to public health.
