Examination of pigs (eight to 10 per farm) slaughtered between December 1978 and March 1979 at abattoirs in southern England indicated that infection with Bordetella bronchiseptica was widespread. The organism was recovered from the nasal cavity of 424 out of 844 (50 per cent) of such pigs and these were distributed among 79 out of 86 (91 per cent) of the herds submitting animals. The sensitivity to sulphonamide or potentiated sulphonamide of 255 of these strains was determined: in 20 out of 70 (25 per cent) herds there was partial or complete resistance to the former drug and, in 16 out of 79 (20 per cent), to the latter also. Despite this general level of infection and bacterial resistance the prevalence and severity of turbinate atrophy was less than in a survey undertaken by others in 1974. Thus about 74 per cent of pigs had no or minor atrophy only and about 10 per cent severe lesions. Some 10 per cent of the farms sent groups in which the majority of the pigs had severe atrophy.
对1978年12月至1979年3月间在英格兰南部屠宰场宰杀的猪（每个农场8至10头）进行检查发现，支气管败血波氏杆菌感染很普遍。在844头此类猪中，有424头（50%）的鼻腔中检出了该病菌，这些猪分布在送来送检猪只的86个猪群中的79个（91%）。测定了其中255个菌株对磺胺或增效磺胺的敏感性：在70个猪群中有20个（25%）对前一种药物存在部分或完全耐药性，在79个猪群中有16个（20%）对后一种药物也存在耐药性。尽管存在这种总体感染水平和细菌耐药性，但鼻甲萎缩的发生率和严重程度低于其他人在1974年进行的一项调查。因此，约74%的猪没有或仅有轻微萎缩，约10%有严重病变。约10%的农场送来的猪群中，大多数猪有严重萎缩。
