We investigated the effects of culling on Bartonella spp. bacteria carriage among urban rats in Canada. We found that the odds of Bartonella spp. carriage increased across city blocks except those in which culling occurred. Removing rats may have prevented an increase in Bartonella spp. prevalence, potentially lowering human health risks.
我们调查了扑杀对加拿大城市老鼠中巴尔通体属细菌携带的影响。我们发现,除了扑杀发生的街区外,巴尔通体属细菌携带的几率在城市街区中呈上升趋势。清除老鼠可能阻止了巴尔通体属细菌流行率的增加,从而降低了人类健康风险。
