Resumo

ABSTRACT Campylobacter jejuni , Campylobacter coli , and Arcobacter spp. were detected in feces of healthy dairy cows by highly specific multiplex-PCR assays. For C. jejuni , at this one-time sampling, cows from 80.6% of farm operations ( n = 31) and 37.7% of individual dairy cattle fecal samples ( n = 2,085) were positive. Farm management factors were correlated with prevalence in herds in which >25% of cows were positive for C. jejuni . Statistical significance was set at a P of 0.20. Using these criteria, application of manure with broadcast spreaders ( P = 0.17), feeding of whole cottonseed or hulls ( P = 0.17) or alfalfa ( P = 0.15), and accessibility of feed to birds ( P = 0.17) were identified as possible risk factors for C. jejuni infection. C. coli was detected in at least one animal in 19.4% of operations and 1.8% of individual cows ( n = 2,085). At the herd level, use of broadcaster spreaders was not a risk factor for C. coli infection. For Arcobacter , cows from 71% of dairy operations ( n = 31) and 14.3% of individual dairy cattle fecal samples ( n = 1,682) were positive. At the herd level, for Arcobacter spp., feeding of alfalfa ( P = 0.11) and use of individual waterers ( P = 0.19) were protective. This is the first description of Arcobacter spp. in clinically healthy dairy cattle and the first attempt to correlate their presence with C. jejuni .
