The epidemiology of animal trichinellosis in China
چکیده انگلیسی

The epidemiology of animal trichinellosis in China based mainly upon original Chinese literature published between 1937 and 2004 is reviewed. The seroprevalence of Trichinella infection in herbivores was 0.7% (2/300) in cattle and 0.8% (4/500) in sheep. The prevalence of trichinellosis in naturally infected cattle was 1.2% (2/163). Trichinella larvae were detected in 1.4% (3/215) of sheep and in 2.1% (1/47) of beef cattle sold at markets. Canine trichinellosis was recorded in 13 Provinces, Autonomous Regions or Municipalities (P/A/M) and the average prevalence of the infection in dogs slaughtered in abattoirs was 16.2% (5654/34,983) ranging from 1.2% to 44.8%, with the highest prevalence located in northeast China. The prevalence in dog meat sold at markets was 3.5% (988/27,898) in 5 P/A. Feline Trichinella infection was reported in 10 P/A/M.The prevalence of Trichinella infection in rats varied from 1.1% (51/459) to 15.1% (50/332). Trichinella larvae were detected in 1.5% (9/587) of house rats (Rattus norvegicus) as well as in 0.8% (3/369) of wild rats (Apodemus chevrieri), and the infection was recorded also in other wildlife (foxes, bears, wild boar, weasels, raccoon dogs, muntjak and bamboo rats). Trichinella larvae were detected in 2.6% (4/156) of weasels (Mustela sibirica), 1.5% (2/135) of shrews (Tupaia belangeri) and 7.7% (1/13) of moles (Parascapter leucurus). All Trichinella isolates from domestic pigs were identified as T. spiralis. Some Trichinella isolates from dogs in north-eastern China were identified as T. nativa, which has muscle larvae that are highly resistant to freezing. Twenty-seven outbreaks of human trichinellosis associated with mutton, dog and game meat occurred in China between 1964 and 2004, but the quarantine of Trichinella larvae in such meat is not mandatory in China at present.
