To investigate the prevalence of spp. in a convenience sample of working farm dogs and their home-kill raw meat diets in Manawatū, New Zealand.
Fifty farms in the Manawatū, with at least three working/herding dogs per farm that were fed raw home-killed meat at least fortnightly, were visited. One sample of dog faeces and one sample of food were collected per farm using convenience sampling. If a dog did not defecate, a sample was obtained by digital recovery. Basic descriptive data for all dogs, meat and farm characteristics were recorded. Stomached meat samples and swabs from faecal samples were pre-enriched in buffered peptone water followed by two selective enrichments with agar subculture. Isolates were confirmed to be spp. by serology and biochemical characterisation.
No spp. were isolated from dog faeces or raw meat samples, giving an observed prevalence rate of 0 (95% CI = 0.0-7.1)%.
In this study, there was no evidence that working farm dogs and their home-kill raw meat represent likely sources of infection with spp.
Although this study found no evidence suggesting that farmers should change their feeding practices, it is based on a small sample, from a single region of New Zealand and involved sampling on one occasion for spp. only. Currently, although the prevalence of spp. carriage appears to be low, feeding raw meat-based diets to working dogs remains a risk and due to the potential zoonotic implications for humans, hygienic measures should be maintained when in contact with dogs and raw meat.
调查新西兰马纳瓦图地区工作农场犬及其家庭宰杀生肉饮食的便利样本中[具体菌名]的流行情况。
走访了马纳瓦图地区的50个农场，每个农场至少有三只工作/放牧犬，且至少每两周喂食一次家庭宰杀的生肉。采用便利抽样法，每个农场采集一份犬粪便样本和一份食物样本。如果犬没有排便，则通过指检获取样本。记录所有犬、肉和农场特征的基本描述性数据。将绞碎的肉样本和粪便样本拭子先在缓冲蛋白胨水中预富集，然后进行两次选择性富集并琼脂传代培养。通过血清学和生化特性鉴定分离株为[具体菌名]。
犬粪便或生肉样本中未分离出[具体菌名]，观察到的流行率为0（95%置信区间=0.0-7.1）%。
在本研究中，没有证据表明工作农场犬及其家庭宰杀的生肉是[具体菌名]感染的可能来源。
尽管本研究没有证据表明农民应改变其喂养方式，但该研究基于新西兰单一地区的小样本，且仅对[具体菌名]进行了一次采样。目前，尽管[具体菌名]携带率似乎较低，但给工作犬喂食生肉饮食仍然存在风险，并且由于对人类可能存在人畜共患病影响，在接触犬和生肉时应保持卫生措施。
