An abattoir survey was carried out on 1657 cattle to determine the incidence and parameters of teat and udder papillomas and their causal viruses. Recent research has characterised six different bovine papillomaviruses of which three have been found to be particularly associated with teat tumours. Of the population studied 37.3 per cent had teat warts and 86.2 per cent of these had multiple infections; 28.4 per cent had papillomas attributed to bovine papillomavirus 1, 88.5 per cent to bovine papillomavirus 5 and 92.3 per cent to bovine papillomavirus 6. There was no predilection site between teats. Herefords and their crosses dominated the breed incidence and showed the highest numbers of warts but it was not possible to make a realistic comparison with other breeds. Dairy cattle were poorly represented. Bovine papillomavirus 4 was never found and from this it was concluded that there is no association between alimentary and teat papillomas. The implications of these findings in terms of prophylaxis and control are discussed.
对1657头牛进行了屠宰场调查，以确定乳头和乳房乳头瘤的发病率、参数及其致病病毒。最近的研究已鉴定出六种不同的牛乳头瘤病毒，其中三种被发现与乳头肿瘤特别相关。在所研究的牛群中，37.3%有乳头疣，其中86.2%有多重感染；28.4%的乳头瘤归因于牛乳头瘤病毒1型，88.5%归因于牛乳头瘤病毒5型，92.3%归因于牛乳头瘤病毒6型。乳头之间没有偏好部位。赫里福德牛及其杂交品种在品种发病率中占主导地位，疣的数量最多，但无法与其他品种进行实际比较。奶牛的代表性不足。从未发现牛乳头瘤病毒4型，由此得出结论，消化道乳头瘤与乳头乳头瘤之间没有关联。讨论了这些发现对预防和控制的意义。
