The prevalence of Campylobacter spp. in cattle in Sokoto State, Nigeria, was determined. The number of samples collected totalled 976, of which 126 (12.9%) yielded Campylobacter spp. The species of Campylobacter isolates from this study were as follows: C. jejuni (65.1%), C. coli (23.0%), C. lari (7.9%), C. hyointestinalis (3.2%) and C. fetus (0.8%). A total of 172 strains of Campylobacter spp. were identified from the positive samples due to identification of more than a single strain (spp.) from a single sample. The strains identified were C. jejuni (62.8%), C. coli (25.0%), C. lari (8.1%), C. hyointestinalis (2.9%) and C. fetus (1.2%). More than one species of Campylobacter was identified in 36.5% of the positive samples. The biotyping in this study revealed C. jejuni biotype I (34.3%) as the most common C. jejuni biotype, while C. jejuni biotype IV (15.7%) was the C. jejuni biotype that was least frequently isolated. However, the most frequently isolated C. coli biotype was biotype I (72.1%) and all the isolates of C. lari were biotype I.
对尼日利亚索科托州牛群中弯曲杆菌属的流行情况进行了测定。总共采集了976份样本，其中126份（12.9%）检测出弯曲杆菌属。本研究中分离出的弯曲杆菌种类如下：空肠弯曲杆菌（65.1%）、大肠弯曲杆菌（23.0%）、海鸥弯曲杆菌（7.9%）、猪肠弯曲杆菌（3.2%）和胎儿弯曲杆菌（0.8%）。由于从单个样本中鉴定出不止一种菌株，因此从阳性样本中总共鉴定出172株弯曲杆菌属菌株。鉴定出的菌株为空肠弯曲杆菌（62.8%）、大肠弯曲杆菌（25.0%）、海鸥弯曲杆菌（8.1%）、猪肠弯曲杆菌（2.9%）和胎儿弯曲杆菌（1.2%）。在36.5%的阳性样本中鉴定出不止一种弯曲杆菌。本研究中的生物分型显示，空肠弯曲杆菌生物型I（34.3%）是最常见的空肠弯曲杆菌生物型，而空肠弯曲杆菌生物型IV（15.7%）是分离频率最低的空肠弯曲杆菌生物型。然而，最常分离出的大肠弯曲杆菌生物型是生物型I（72.1%），并且所有分离出的海鸥弯曲杆菌都是生物型I。
