广州市部分区域猫泛白细胞减少症流行现状调查

目的]了解猫泛白细胞减少症病毒在广州家猫和流浪猫中的流行情况,分析FPV威胁广州家猫和流浪猫的潜在风险。方法]采用猫泛白细胞减少症免疫胶体金快速检测试纸条和PCR检测方法对广州5家动物医院采集的3 004份猫样品进行检测与分析。结果]猫泛白细胞减少症免疫胶体金快速检测试纸条检出10份疑似猫泛白细胞减少症阳性样品,采用猫泛白细胞减少症PCR检测方法检出13份猫泛白细胞减少症阳性样品。13份阳性样品来源于96份具有临床症状且未免疫样品,49份家猫样品中有6份呈阳性,47份流浪猫样品中有7份呈阳性,阳性率分别为12.2%(6/49)和14.9%(7/47),发病季节以9~10月多发,发病年龄集中在0~6月龄。结论]与外界接触和未免疫疫苗可能是导致猫感染FPV的重要原因。因此,家猫加强疫苗接种,减少与未知免疫背景的猫只接触,减少家猫感染FPV的潜在风险。

Epidemiological Survey of Feline Panleukopenia Virus in Partial Region of Guangzhou City

Objective] To understand the prevalence of feline panleukopenia virus and analyze the potential risk of feline panleukopenia virus in Guangzhou domestic and wild cats. Method] 3004 cat samples of 5 animal hospitals were detected and analyzed by two methods of FPV immune colloidal gold test strip and PCR.Result] 10 positive samples were detected by the method of immune colloidal gold test strip from 3004 cat samples, but 13 positive samples were detected by the method of PCR from 3004 cat samples.13 positive samples were from 96 unim-munized samples with clinical symptoms including 6 positive samples from 49 domestic cats and 7 positive samples from 47 wild cats.The posi-tive rates respectively were 12.2% (6/49) and 14.9% (7/47).The morbidity ages and seasons of these samples were concentrated in 0-6 months old and 9-10 months old.Conclusion] The important reasons of cats infected with FPV may be contact with the outside world and no vaccination.Therefore, there are two measures to reduce the potential risk of domestic cats infected with FPV including vaccination and re-duce contact with unknown immune background cats.
