亚利桑那州科奇斯县10月29日确认全州首例新世界螺旋蝇病例：一只犬只伤口发现蝇蛆、农业厅吁畜主密切监测
亚利桑那州科奇斯县10月29日确认该州首例新世界螺旋蝇病例，感染动物为一只犬只。据亚利桑那州农业厅通报，当地一名兽医10月26日晚间检查这只犬只时，在其背部伤口发现大量与新世界螺旋蝇特征相符的蝇蛆，随后病例获得确认。新世界螺旋蝇是一种蝇类的幼虫，会在温血动物的开放性伤口与体腔开口处产卵，幼虫以活体组织为食，可对牲畜与宠物造成严重伤害。农业厅表示，部门保持戒备并持续监测，敦促所有牲畜主、宠物主与动物行业伙伴密切观察动物，发现与新世界螺旋蝇相符的异常伤口立即报告。此前，新世界螺旋蝇已在得克萨斯州与新墨西哥州的牲畜与家养动物中得到确认，10月21日还在得克萨斯州佩科斯县一头猎获的麋鹿身上首次于野生动物中检出，农业部门正加强相关区域的监测。
Cochise County, Arizona: State's First New World Screwworm Case Confirmed Oct. 29: Maggots Found in a Dog's Wound, Agriculture Department Urges Close Monitoring
Arizona's Cochise County confirmed the state's first case of New World screwworm on October 29, in a dog. According to the Arizona Department of Agriculture, a local veterinarian examining the dog on the evening of October 26 found a large number of maggots consistent with New World screwworm characteristics in a wound on its back, and the case was subsequently confirmed. The New World screwworm is the larva of a fly that lays eggs in open wounds and body openings of warm-blooded animals; the larvae feed on living tissue and can seriously harm livestock and pets. The department said it remains prepared and vigilant and continues monitoring, urging all livestock owners, pet owners and animal industry partners to watch animals closely and immediately report any unusual wounds consistent with New World screwworm. New World screwworm had previously been confirmed in livestock and domestic animals in Texas and New Mexico, and on October 21 it was detected for the first time in wildlife, in a harvested elk in Pecos County, Texas; agricultural agencies are stepping up monitoring in related areas.
