Abstract

The aim of this study was to determine the seroprevalence of Salmonella spp., Mycobacterium bovis and Brucella spp., together with associated risk factors, in pigs from various farms in seven regions of Colombia. A total of 350 blood samples were obtained from pigs at different stages in the production cycle of 23 farms, which were tested using the enzyme-linked immunosorbent assay (ELISA) diagnostic kits PigtypeÂ®-Salmonella Ab (QiagenÂ®, Hilden, Germany), INgezim TB porcine and INgezim Brucella porcine (IngenasaÂ®, Madrid, Spain). The overall seroprevalence for Salmonella spp. was 42.85% (n = 150) and, for M. bovis, it was 5.42% (n = 19). No positive samples were detected for Brucella spp. In the farms evaluated, the presence of pests, such as rodents, was found to be the management variable with a statistically significant association with seropositivity for Salmonella spp. and M. bovis. The results suggest that, at some point in the primary production cycle, pigs came into contact with zoonotic bacteria, resulting in seropositivity, which may pose a risk to public health and national pig production.

哥伦比亚养猪场三种人畜共患病细菌抗体及相关危险因素的评估。

本研究的目的是确定沙门氏菌、牛分枝杆菌和布鲁氏菌的血清患病率，以及相关的危险因素，这些猪来自哥伦比亚7个地区的不同农场。从23个养殖场的不同生产阶段的猪中采集了350份血液样本，使用酶联免疫吸附试验(ELISA)诊断试剂盒PigtypeÂ®-沙门氏菌Ab (QiagenÂ®，Hilden，德国)、INgezim TB猪和INgezim布鲁氏菌猪(IngenasaÂ®，西班牙马德里)进行检测。沙门氏菌总血清阳性率为42.85% (n = 150)，牛分枝杆菌总血清阳性率为5.42% (n = 19)。没有检测到布鲁氏菌阳性样本。在评估的农场中，发现啮齿动物等害虫的存在是管理变量，与沙门氏菌和牛分枝杆菌的血清阳性有统计学意义的关联。结果表明，在初级生产周期的某个时刻，猪与人畜共患病细菌接触，导致血清阳性，这可能对公共卫生和国家生猪生产构成风险。
