Two hundred and twenty-six cats from the Veterinary Medical Teaching Hospital (VMTH), a cat shelter, and a purebred cattery were tested for chronic feline calicivirus (FCV), feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infections. Chronic oral carriage of FCV was present in about one-fifth of the cats in each of the groups. FIV infection was not present in the purebred cattery, was moderately prevalent (8%) in the pet population of cats examined at the VMTH for various complaints and was rampant in the cat shelter (21%). Unexpectedly high FeLV infection rates were found in the hospital cat population (28%) and in the purebred cattery (36%), but not in the cat shelter (1.4%). FCV and FeLV infections tended to occur early in life, whereas FIV infections tended to occur in older animals. From 43 to 100% of the cats in these environments had oral cavity disease ranging from mild gingivitis (23-46%), proliferative gingivitis (18-20%), periodontitis (3-32%) and periodontitis with involvement of extra-gingival tissues (7-27%). Cats infected solely with FCV did not have a greater likelihood of oral lesions, or more severe oral disease, than cats that were totally virus free. This was also true for cats infected solely with FeLV, or for cats dually infected with FeLV and FCV. Cats infected solely with FIV appeared to have a greater prevalence of oral cavity infections and their oral cavity disease tended to be more severe than cats without FIV infection. FIV-infected cats that were coinfected with either FCV, or with FCV and FeLV, had the highest prevalence of oral cavity infections and the most severe oral lesions.
对来自兽医教学医院（VMTH）、一家猫咪收容所和一家纯种猫繁育场的226只猫进行了慢性猫杯状病毒（FCV）、猫白血病病毒（FeLV）和猫免疫缺陷病毒（FIV）感染检测。每组中约五分之一的猫存在FCV慢性口腔携带情况。纯种猫繁育场中不存在FIV感染，在VMTH因各种病症接受检查的宠物猫群体中FIV感染中度流行（8%），而在猫咪收容所中FIV感染很猖獗（21%）。在医院的猫群体（28%）和纯种猫繁育场（36%）中发现FeLV感染率意外地高，但在猫咪收容所中FeLV感染率较低（1.4%）。FCV和FeLV感染往往在生命早期发生，而FIV感染往往发生在年龄较大的动物身上。在这些环境中，43%至100%的猫患有口腔疾病，范围从轻度牙龈炎（23 - 46%）、增生性牙龈炎（18 - 20%）、牙周炎（3 - 32%）到累及龈外组织的牙周炎（7 - 27%）。仅感染FCV的猫与完全无病毒的猫相比，出现口腔病变或更严重口腔疾病的可能性并无增加。仅感染FeLV的猫，或同时感染FeLV和FCV的猫也是如此。仅感染FIV的猫似乎比未感染FIV的猫口腔感染患病率更高，且其口腔疾病往往更严重。同时感染FCV或同时感染FCV和FeLV的FIV感染猫，口腔感染患病率最高，口腔病变最严重。
