The aim of the study was to evaluate the occurrence of spp. in food samples collected from Sicilia region. A total of 91 food products of animal origin (41 meat, 17 fresh milk, 18 shellfish) and 15 samples of fresh vegetables, were examined by cultural method and confirmed by biochemical analysis and PCR methods. The detection of spp. was performed, after selective enrichment, on two selective agar plates: Arcobacter agar and mCCD (modified charcoal cefoperazone deoxycholate) agar supplemented with CAT (Cefoperazone, Amphotericin B and Teicoplanin). species were isolated using the membrane filtration technique. In 13 (14.3%) out of the 91 tested samples, the presence of spp. was found: the isolates were confirmed by multiplex PCR and identified as belonging to the species and The highest prevalence rate was observed in chicken meat (8.8%) followed by shellfish (3.3%). Negative results have been obtained for raw milks and vegetables samples. The preliminary study highlights the importance of this emerging pathogen and the need for further studies on its prevalence and distribution in different types of food for human consumption.
本研究的目的是评估从西西里岛地区采集的食品样本中弧菌属物种的出现情况。通过培养方法对总共91种动物源性食品(41种肉类、17种鲜奶、18种贝类)和15种新鲜蔬菜样本进行检测,并通过生化分析和PCR方法进行确认。在选择性富集后,在两种选择性琼脂平板上进行弧菌属物种的检测:弧菌琼脂和添加了头孢哌酮、两性霉素B和替考拉宁的改良木炭头孢哌酮脱氧胆酸盐(mCCD)琼脂。使用膜过滤技术分离弧菌属物种。在91个测试样本中的13个(14.3%)中,发现了弧菌属物种:分离株通过多重PCR得到确认,并鉴定为属于该物种和该物种。鸡肉中的患病率最高(8.8%),其次是贝类(3.3%)。生牛奶和蔬菜样本的检测结果为阴性。初步研究突出了这种新兴病原体的重要性,以及对其在不同类型人类食用食品中的患病率和分布进行进一步研究的必要性。
