The present study was initiated to ascertain the level of shedding of salmonellae by dogs in Makurdi area and to highlight the risk of infection for dog-owners.
Rectal swabs from 200 dogs from different locations in the study area were examined in the study. The samples were cultured for salmonellae using Rappaport-Vassiliadis enrichment broth (Oxoid) and brilliant green agar (Oxoid). Suspected isolates were serologically identified.
Overall, organisms were isolated from 11 (5.5%) of the 200 dogs sampled. Prevalence rates of 5.6% and 4.5% were recorded for apparently healthy and clinically sick dogs, respectively. was respectively isolated from 4.1% to 9.1% of male and female dogs. Dogs aged 4 years and above recorded the highest prevalence rate. The study revealed a low prevalence rate in Nigerian local breed (mongrels) and high prevalence rates in exotic breeds of dogs.
The isolation of salmonellae in apparently healthy and clinically sick dogs in this study indicates a carrier status which may constitute a serious problem in disease control in the study area. The lower prevalence rate of infection in mongrels could be an indication of resistance to in local breeds of dogs and should generate interest in research in the pathogenicity and pathogenesis of salmonellae in mongrels.
开展本研究以确定马库尔迪地区犬类沙门氏菌的排泄水平，并强调犬主的感染风险。
本研究检测了来自研究区域不同地点的200只犬的直肠拭子。样本使用Rappaport-Vassiliadis增菌肉汤（Oxoid）和亮绿琼脂（Oxoid）进行沙门氏菌培养。对疑似分离株进行血清学鉴定。
总体而言，在200只采样犬中，有11只（5.5%）分离出了菌株。明显健康和临床患病犬的患病率分别为5.6%和4.5%。雄性和雌性犬的分离率分别为4.1%至9.1%。4岁及以上的犬患病率最高。研究显示，尼日利亚本地品种（杂种犬）的患病率较低，而外来品种犬的患病率较高。
本研究中在明显健康和临床患病犬中分离出沙门氏菌，表明存在携带状态，这可能在研究区域的疾病控制中构成严重问题。杂种犬中感染率较低可能表明本地品种犬对感染具有抵抗力，这应该会引发对杂种犬沙门氏菌致病性和发病机制研究的兴趣。
