■旋毛虫病是非洲一种被忽视和新兴的食源性人畜共患病。旋毛虫感染是通过食用生的或未煮熟的感染肉和肉制品而发生的。本研究旨在评估猪的管理实践,并确定猪和疣猪对旋毛虫的暴露。在塞内加尔北部地区。
■对40个养猪户进行了调查和观察,以评估有关旋毛虫的饲养实践。生命周期。此外,提取了201个猪肉汁和83个疣猪肉汁,并通过间接酶联免疫吸附试验检测了抗旋毛虫抗体。
■大多数(97%)的农场实行传统的耕作制度,85%的农场自由放养猪。农场的当地猪种没有住房和补充饲料。一些农民(27.5%)使用屠宰废物喂养猪,农民不知道自由放养是毛毛虫感染的感染源。他们也没有意识到一些猪疾病可以传播给人类。在猪中,旋毛虫感染的血清阳性率为10.9%(95%置信区间[CI]:6.6-15.2%),在疣猪中为10.8%(95%CI:4.16-17.52%),男性的血清阳性率明显高于女性(9.2%;95%CI:6.6-37.8%)(p<0.05)。
■确认接触旋毛虫。在这一地区,如果不尊重农业条件和健康监测系统,猪和疣猪显示出将这种疾病传播给人类的巨大风险。然而,需要采取控制措施,以减少将旋毛虫感染传播给人类的任何风险。
UNASSIGNED: Trichinellosis is a neglected and emerging foodborne zoonosis in Africa. Trichinella infection occurs through the consumption of raw or undercooked infected meat and meat products. This study aimed to assess pigs\' management practices and determine the exposure of pigs and warthogs to Trichinella spp. in the northern area of Senegal.
UNASSIGNED: Surveys and observations were carried out among 40 pig farmers to assess husbandry practices regarding Trichinella spp. life cycle. In addition, 201 pig meat juices and 83 warthog meat juices were extracted and tested for anti-Trichinella antibodies by indirect enzyme-linked immunosorbent assay.
UNASSIGNED: Most (97%) of farms practiced a traditional farming system with free-ranging of pigs in 85% of farms. Farms had local pig breed without housing and supplementary feeding. Some farmers (27.5%) used slaughter waste to feed pigs and farmers were not aware that free-range farming is a source of infection to Trichinella infection. They were also unaware that some pig diseases could be transmitted to humans. The seroprevalence of Trichinella infection was 10.9% (95% confidence interval [CI]: 6.6-15.2%) in pigs and 10.8% (95% CI: 4.16-17.52%) in warthogs with significantly higher seroprevalence in male (22.2%: 95% CI: 6.6-37.8%) compared to female (9.2%; 95% CI: 4.9-13.5%) (p < 0.05).
UNASSIGNED: The confirmation of exposure to Trichinella spp. in this area in pigs and warthogs shows a significant risk of transmission of this disease to humans if the farming conditions and the health surveillance system are not respected. However, control measures are needed to reduce any risk of transmission of Trichinella infection to humans.
