摘要: Abstract The objective of the present study was to study, under field conditions, potential associations between gastrointestinal nematode parasitism and subclinical mastitis in ewes during lactation period. Faecal milk samples were collected from 240 16 farms, for parasitological bacteriological plus cytological examination, respectively. In population sampled, prevalence infection 63.0%; mean faecal count 357.7 ± 32.4 eggs per gram (epg); Teladorsagia spp. larvae identified more frequently coprocultures (median proportion among farms: 53.0%). 22.6%; coagulase-negative Staphylococcus as causal agents (64.7% isolates recovered cases disease). There clear evidence that higher with than without: 26.4% 16.1% (P = 0.047), Further, high epg: 31.1% versus 18.6% low epg 0.027). Mean counts significantly higher: 500 ± 84 (mean standard error mean), healthy ewes: 316 36 0.024). findings further underline importance concurrent parasitic bacterial infections. Moreover, results also suggest factors can play a role development ewes.
