A total of 1590 caves were investigated between May 1972 and December 1975. Twenty-two per cent were treated for respiratory disease and 2 . 5% died of pneumonia. Almost 80% of the respiratory illness occurred in six sharp outbreaks. Samples of virology were collected routinely from 127 healthy calves and from 354 calves treated for respiratory signs and comprised 1143 nasopharyngeal swabs and 1069 sera. Virus infections were detected on 540 occasions including 135 by parainfluenzavirus type 3 (Pi-3), 78 by respiratory syncytial virus (RSV), 103 by rhinovirus, 49 by bovine virus diarrhoea virus (BVDV), 29 by adenoviruses, 53 by reoviruses and 88 by enteroviruses. The seasonal and age distribution of infections differed between viruses. Only infections by RSV, Pi-3 and BVDV were significantly associated with disease.
在1972年5月至1975年12月期间,共对1590个洞穴进行了调查。22%的洞穴接受了呼吸道疾病治疗,2.5%死于肺炎。近80%的呼吸道疾病呈6次急剧爆发。定期从127头健康犊牛和354头有呼吸道症状的犊牛身上采集病毒学样本,包括1143份鼻咽拭子和1069份血清。共检测到540次病毒感染,其中3型副流感病毒(Pi-3)感染135次、呼吸道合胞病毒(RSV)感染78次、鼻病毒感染103次、牛病毒性腹泻病毒(BVDV)感染49次、腺病毒感染29次、呼肠孤病毒感染53次、肠道病毒感染88次。不同病毒的感染季节和年龄分布有所不同。只有RSV、Pi-3和BVDV感染与疾病显著相关。
