    摘要:

    为了解近年来京津冀地区猫传染性腹膜炎(FIP)的发生发展及流行规律,丰富和更新FIP流行病学数据,2018—2020年从京津冀地区73家动物医院搜集725例疑似猫冠状病毒(FCoV)感染病例的临床检查信息,同时将病例对应的积液、粪便等样本进行分子生物学检测,结合临床信息和检测结果,对FIP流行情况进行三间分布描述和统计学分析。结果显示:京津冀地区疑似病例的FCoV阳性检出率较高,为75.0%(544/725),其中传染性腹膜炎型308例,占42.5%。308例FIP确诊病例中,298例(96.7%)出现了长期反复发烧、腹腔或胸腔积液等湿性临床症状;春、夏、秋、冬四季的FIP阳性检出率分别为37.4%、40.1%、52.8%和37.3%,差异有统计学意义(χ2=18.051,P<0.01);各品种猫均可发病,其中英国短毛猫(36.0%)、中华田园猫(15.9%)和美国短毛猫(26.0%)FIP阳性检出率较高;雌猫的FIP阳性检出率为36.8%,雄猫为45.3%,二者差异有统计学意义(χ2=4.840,P<0.05);未绝育猫(251例)高于绝育猫(57例),差异显著(P<0.05);各个年龄段猫均可感染FCoV甚至发展为FIP,阳性检出率差异具有统计学意义(P<0.05),其中以2月龄到1岁的阳性检出率最高(54.8%)。结果表明:京津冀地区FCoV感染及FIP发生较普遍;FIP发生与年龄、性别、品种、绝育情况和季节相关性较高,多发于幼龄、青壮年以及纯种、未绝育的雄性猫,夏秋高温季多发,主要表现湿性临床症状。结果提示,应重视FIP预防,针对其流行特点制定相应措施,尽早诊断,尽早介入治疗。

    Abstract:

    In order to identify the rule of occurrence,development and prevalence of feline infectious peritonitis(FIP)in Beijing-Tianjin-Hebei region in recent years,and to enrich and update relevant epidemiological data,clinical examination information concerning 725 suspected cases of feline coronavirus(FCoV)infection were collected from 73 animal hospitals in the region during 2018 to 2020,followed by molecular biological detection of corresponding effusion,feces and other samples,then the prevalence status of FIP was described in terms of time,region and population distribution and statistically analyzed in combination with clinical information and test results. The results showed that the positive detection rate of FCoV in suspected cases was 75.03%(544/725)in the region,including 308 cases of infectious peritonitis,accounting for 42.5%. Wet clinical symptoms including repeated fever for long term and abdominal cavity or pleural effusion appeared in 298(96.7%)out of 308 confirmed cases infected with FIP;the positive detection rates were 37.4%,40.1%,52.8% and 37.3% respectively in spring,summer,autumn and winter,with difference of statistical significance(χ2=18.051,P<0.01);all species of cats could be infected,specifically,the positive detection rates were higher in British Shorthairs(36.0%),Chinese Pastoral Cats(15.9%)and American Shorthairs(26.0%);36.8% and 45.3% respectively in female cats and male ones,with difference of statistical significance(χ2=4.840,P<0.05);and lower in sterilized cats(57 cases)compared to unsterilized ones(251 cases),with significant difference(P<0.05);cats at all ages could be infected with FCoV even FIP,the difference of positive detection rate was of statistical significance(P<0.05),especially the cats at 2 to 12 months ages(54.8%). It was concluded that FCoV infection and the occurrence of FIP were widely distributed in Beijing-Tianjin-Hebei region,the occurrence of FIP was closely related to the age,sex,species and sterilization of cats as well as season,mostly occurred in the young and young adult cats,purebred and unsterilized cats as well as the unsterilized male cats,and frequently in the seasons with high temperature including summer and autumn,mainly with wet clinical symptoms. It was recommended to give priority to prevention of FIP,develop corresponding measures according to its characteristics,diagnose and cure any cases as soon as possible.
