To estimate prevalences of roundworm, hookworm, and whipworm infections in pet cats in the United States and identify risk factors for parasitism.
Retrospective period prevalence survey.
356,086 cats examined at 359 private veterinary hospitals during 2003.
Electronic medical records were searched to identify cats for which fecal flotation tests had been performed and to determine proportions of test results positive for roundworms, hookworms, and whipworms. Potential risk factors for roundworm and hookworm infection were identified by means of multivariate logistic regression analysis.
A total of 80,278 tests were performed on fecal samples from 66,819 cats. Calculated prevalences of roundworm, hookworm, and whipworm infection were 2.92%, 0.63%, and 0.031%, respectively. Age, reproductive status, breed, and season were significant risk factors for roundworm infection, with cats < 4 years old; sexually intact cats; mixed-breed cats; and cats examined during the summer, fall, or winter more likely to be infected. Age, reproductive status, and season were significant risk factors for hookworm infection, with cats < 1 year old, sexually intact cats, and cats examined during the summer more likely to be infected. Regional differences in prevalences of roundworm and hookworm infection were found.
Results suggest that prevalences of nematode infections among pet cats in the United States may be lower than previously suspected on the basis of prevalences reported among cats in humane shelters and those reported in more geographically focused studies.
估算美国宠物猫蛔虫、钩虫和鞭虫感染的患病率，并确定寄生虫感染的风险因素。
回顾性期间患病率调查。
2003年期间在359家私人兽医医院接受检查的356,086只猫。
检索电子病历，以确定已进行粪便浮选试验的猫，并确定蛔虫、钩虫和鞭虫检测结果呈阳性的比例。通过多变量逻辑回归分析确定蛔虫和钩虫感染的潜在风险因素。
共对66,819只猫的粪便样本进行了80,278次检测。计算得出的蛔虫、钩虫和鞭虫感染患病率分别为2.92%、0.63%和0.031%。年龄、生殖状态、品种和季节是蛔虫感染的重要风险因素，4岁以下的猫、未绝育的猫、混种猫以及在夏季、秋季或冬季接受检查的猫更容易感染。年龄、生殖状态和季节是钩虫感染的重要风险因素，1岁以下的猫、未绝育的猫以及在夏季接受检查的猫更容易感染。发现蛔虫和钩虫感染患病率存在地区差异。
结果表明，美国宠物猫线虫感染的患病率可能低于根据动物收容所猫的患病率以及更具地域针对性研究报告所推测的患病率。
