Salmonella is the most important causes of foodborne illness especially from poultry and poultry products. So the aim of this study was to carryout phenotypic characterization, antimicrobials susceptibility pattern and risk factors of Salmonella isolates from farms and markets eggs, cloacae swabs of chickens and stool of egg collectors. A cross-sectional study was conducted from January 2018 to September 2018. Samples were, processed; Salmonella was isolated, phenotypically identified by OmniLog and antimicrobials susceptibility were carried out.
Over all; 11 (2.65%) of Salmonella enterica were phenotypically characterized out of 415 samples from farms egg content (n = 83), farms eggshell (n = 83), cloacae (n = 83), market eggshell (n = 83) and market egg contents (n = 83) with 2.4%, 0%, 2.4%, 4.8% and 3.6% prevalence, respectively. Out of isolates, 8 (72.72%) displayed multidrug resistance. All isolates showed susceptibility to Gentamicin, Kanamycin and Streptomycin. Lack of separating cracked eggs, washing hand, eggs stay longer unsold, and mixing excreta with feed were associated risk factors for Salmonella presence (P-value < 0.05). The presence of drug resistant Salmonella enterica within egg/and chicken can pose serious health problem. Good hygienic practices are important to reduce risk factors of Salmonella contamination.
沙门氏菌是食源性疾病的最重要病因，尤其是来自家禽和家禽产品的病因。因此，本研究的目的是对来自农场和市场鸡蛋、鸡泄殖腔拭子以及收蛋员粪便中的沙门氏菌分离株进行表型特征分析、抗菌药物敏感性模式分析和风险因素分析。于2018年1月至2018年9月进行了一项横断面研究。对样本进行处理；分离出沙门氏菌，通过全自动微生物鉴定系统进行表型鉴定，并进行抗菌药物敏感性分析。
总体而言；在来自农场鸡蛋内容物（n = 83）、农场蛋壳（n = 83）、泄殖腔（n = 83）、市场蛋壳（n = 83）和市场鸡蛋内容物（n = 83）的415个样本中，有11株（2.65%）肠炎沙门氏菌得到表型特征分析，其患病率分别为2.4%、0%、2.4%、4.8%和3.6%。在分离株中，8株（72.72%）表现出多重耐药性。所有分离株对庆大霉素、卡那霉素和链霉素敏感。未分离破裂鸡蛋、洗手、鸡蛋滞销时间过长以及粪便与饲料混合是沙门氏菌存在的相关风险因素（P值<0.05）。鸡蛋/和鸡体内存在耐药肠炎沙门氏菌会带来严重的健康问题。良好的卫生 practices 对于降低沙门氏菌污染的风险因素很重要。 （注：原文中“Good hygienic practices”中的“practices”翻译为“措施”更合适，但按照要求未添加解释，此处保留英文形式）
