Abstract

A total of 106 beef samples which consisted of local (n = 59) and imported (n = 47) beef and 180 milk samples from cows (n = 86) and goats (n = 94) were collected from Selangor, Malaysia. Overall, 30.2% (32 of 106) of beef samples were found positive for Arcobacter species. Imported beef was significantly more contaminated (46.80%) than local beef (16.9%). Arcobacter butzleri was the species isolated most frequently from imported (81.8%) and local (60%) beef, followed by Arcobacter cryaerophilus in local (33.3%) and imported (18.2%) beef samples. Only one local beef sample (10%) yielded Arcobacter skirrowii. Arcobacter species were detected from cow's milk (5.8%), with A. butzleri as the dominant species (60%), followed by A. cryaerophilus (40%), whereas none of the goat's milk samples were found positive for Arcobacter. This is the first report of the detection of Arcobacter in milk and beef in Malaysia.

摘要

共采集了 106 份来自马来西亚雪兰莪州的牛肉样本（本地牛肉 59 份，进口牛肉 47 份）和 180 份来自奶牛（86 份）和山羊（94 份）的牛奶样本。总体而言，30.2%（106 份牛肉样本中有 32 份）的牛肉样本被检测出弯曲菌属阳性。进口牛肉的污染率（46.80%）明显高于本地牛肉（16.9%）。从进口牛肉（81.8%）和本地牛肉（60%）中最常分离出的弯曲菌属是 Butzleri 亚种，其次是 Cryaerophilus 亚种，分别占本地（33.3%）和进口（18.2%）牛肉样本的 33.3%和 18.2%。仅从一份本地牛肉样本（10%）中分离出 Skirrowii 亚种。在牛奶中检测到了弯曲菌属（5.8%），其中 Butzleri 亚种是优势种（60%），其次是 Cryaerophilus 亚种（40%），而山羊奶样本中均未检测到弯曲菌属。这是首次在马来西亚的牛奶和牛肉中检测到弯曲菌属。
