To determine the prevalence of infectious diseases of animal and zoonotic importance in cats and dogs rescued and transferred from the Gulf Coast region following Hurricane Katrina.
Cross-sectional study.
414 dogs and 56 cats rescued and transferred from the Gulf Coast region within 4 months after the hurricane.
EDTA-anticoagulated blood and serum samples were tested via PCR and serologic assays for infectious diseases.
In dogs, prevalence was highest for anti-West Nile virus (WNV) antibodies (218/390 [55.9%]), Dirofilaria immitis antigen (195/400 [48.8%]), anti-Toxoplasma gondii antibodies (92/366 [25.1%]), and hemotropic mycoplasma DNA (40/345 [11.9%]). The DNA of Bartonella spp, Ehrlichia spp, or Babesia spp or anti-canine influenza virus antibodies were identified in < 2% of dogs. In cats, prevalence was highest for antibodies against Bartonella spp and DNA of Bartonella spp combined (49/55 [89.1 %]), anti-T gondii antibodies (13/55 [23.6%]), hemotropic mycoplasma DNA (5/47 [10.6%]), anti-WNV antibodies (5/48 [10.4%]), D immitis antigen (4/50 [8.0%]), and anti-FIV antibodies (4/56 [7.1%]). A total of 308 (74.4%) dogs and 52 (92.9%) cats had evidence of previous or current vector-borne infections.
Cats and dogs rescued from the disaster region had evidence of multiple infectious diseases. The dispersal of potentially infectious animals to other regions of North America where some infections were not typically found could have contributed to new geographic ranges for these organisms or to underdiagnosis in affected animals because of a low index of suspicion in regions with low disease prevalence.
确定在卡特里娜飓风过后从墨西哥湾沿岸地区营救并转移的猫和狗中具有动物源性和人畜共患病重要性的传染病的流行情况。
横断面研究。
在飓风过后4个月内从墨西哥湾沿岸地区营救并转移的414只狗和56只猫。
通过聚合酶链反应（PCR）和血清学检测对乙二胺四乙酸（EDTA）抗凝血液和血清样本进行传染病检测。
在狗中，抗西尼罗河病毒（WNV）抗体（218/390 [55.9%]）、犬恶丝虫抗原（195/400 [48.8%]）、抗弓形虫抗体（92/366 [25.1%]）和嗜血性支原体DNA（40/345 [11.9%]）的流行率最高。在不到2%的狗中检测到巴尔通体属、埃立克体属或巴贝斯虫属的DNA或抗犬流感病毒抗体。在猫中，巴尔通体属抗体和巴尔通体属DNA合并出现的流行率最高（49/55 [89.1%]），抗弓形虫抗体（13/55 [23.6%]），嗜血性支原体DNA（5/47 [10.6%]），抗西尼罗河病毒抗体（5/48 [10.4%]），犬恶丝虫抗原（4/50 [8.0%]）和抗猫免疫缺陷病毒抗体（4/56 [7.1%]）。共有308只（74.4%）狗和52只（92.9%）猫有既往或当前媒介传播感染的证据。
从灾区营救的猫和狗有多种传染病的证据。潜在感染动物向北美其他通常未发现某些感染的地区扩散，可能导致这些病原体出现新的地理分布范围，或者由于疾病流行率低的地区怀疑指数低，导致受影响动物的诊断不足。
