Vector Control Efficacy Of Fly Nets On Preventing Bovine Leukemia Virus Transmission
JOURNAL OF VETERINARY MEDICAL SCIENCE(2018)
摘要
Bovine leukemia virus (BLV) is horizontally transmitted among cattle through infected blood. This 3-year field study (2013-2016) aimed to confirm the potential of the blood-sucking stable fly as a risk factor of BLV transmission and to determine the efficacy of vector control on preventing the transmission of BLV. The BLV-positive conversion rate during summer was higher than that during winter in a model dairy farm, where many stable flies were observed during the summer. After fly nets were fixed onto the barn to prevent fly invasion, the BLV-positive conversion rate during the summer was significantly decreased compared with that in the absence of fly nets (P<0.01). These findings suggest that vector control using a fly net may inhibit BLV transmission.
