Digital dermatitis (DD) is a highly contagious and infectious disease in cattle which has a considerable negative economic impact worldwide, and adversely affects animal welfare. Members of the genus are the only bacterial agents for which there is consistent evidence of participation in DD lesions. In Chile, DD has been described since the 1990s, but only under a clinical approach. To date, the presence of the pathogenic agent has not been confirmed in Chile by any type of confirmatory microbiological diagnosis. The aim of the present study was to detect the presence of spp. DNA in lesions consistent with DD, in Chilean dairy cattle for the first time. We provide PCR confirmation of spp. in Chilean dairy cattle affected by DD. The high rate of positive results, as well as the proportion of the main species involved, is in line with what have been described in published studies elsewhere. Future herd control plans should benefit from the molecular detection of these pathogenic bacteria associated with DD.
趾间皮炎（DD）是牛的一种高度传染性疾病，在全球范围内造成了相当大的负面经济影响，并对动物福利产生不利影响。该属成员是唯一有确凿证据参与DD病变的细菌病原体。在智利，自20世纪90年代以来就已描述了趾间皮炎，但仅采用临床方法。迄今为止，智利尚未通过任何类型的确诊微生物诊断证实病原体的存在。本研究的目的是首次在智利奶牛中检测与趾间皮炎相符的病变中是否存在该属细菌的DNA。我们通过PCR证实了智利患趾间皮炎的奶牛中存在该属细菌。高阳性率以及主要相关菌种的比例与其他地方发表的研究中所描述的一致。未来的牛群控制计划应受益于对这些与趾间皮炎相关的致病细菌的分子检测。
