An investigation of feline respiratory tract disease (FRD) was made involving 65 affected cats (group 1) and 65 control cats (group 2) matched for age, sex, and residence. Feline calicivirus strains (FCV), feline herpesvirus-1 (FHV-1), or both, were isolated from 59% of group 1 cats and from 7% of group 2 cats. Isolation of these viruses showed a significantly greater (P < 0.05) relative risk for group 1 cats. Virus isolations were three times more frequent from males than from females older than 1 year (both groups), but were equally distributed between males and females younger than 1 year. Bacteria and fungi had a secondary role in both FCV- and FHV-1 associated FRD. Intestinal infections of Ancylostoma spp, Dipylidium caninum, and Toxocara cati were diagnosed more frequently in group 1 cats than in control (group 2). Paragonimus kellicotti was diagnosed in 3 group 1 cats, Taenia taeniaeformis in 1 group 1 cat, Isospora rivolta in 1 group 1 cat, and Giardia cati in 1 control cat. The present study supports the current concept of a primary viral cause for development of FRD.
对猫呼吸道疾病（FRD）进行了一项调查，涉及65只患病猫（第1组）和65只对照猫（第2组），两组在年龄、性别和居住地方面相匹配。从59%的第1组猫和7%的第2组猫中分离出猫杯状病毒株（FCV）、猫疱疹病毒1型（FHV-1）或两者。这些病毒的分离显示第1组猫的相对风险显著更高（P<0.05）。1岁以上的雄性猫（两组）病毒分离频率是雌性猫的三倍，但1岁以下的雄性和雌性猫中病毒分离分布相同。在与FCV和FHV-1相关的FRD中，细菌和真菌起次要作用。第1组猫中钩虫属、犬复孔绦虫和猫弓首蛔虫的肠道感染诊断频率高于对照组（第2组）。在3只第1组猫中诊断出卫氏并殖吸虫，在1只第1组猫中诊断出带状绦虫，在1只第1组猫中诊断出里氏等孢球虫，在1只对照猫中诊断出猫贾第虫。本研究支持目前关于FRD发病主要由病毒引起的观点。
