The role of tabanids in the mechanical transmission of anaplasmosis was further clarified by determining the number of horse fly bites needed to transmit the disease and the length of time that horse flies remain mechanically infective. Transmission of anaplasmosis from acutely infected calves to susceptible splenectomized calves was accomplished with as few as 10 horse fly bites. These flies were shown to remain mechanically infective for at least 2 hours after they had obtained a partial blood meal from an acutely infected calf. These data emphasize the efficiency of horse flies in the mechanical transmission of anaplasmosis and indicate that relatively short-distance barriers may not be adequate to prevent transmission between infected and noninfected herds.
通过确定传播该疾病所需的厩螫蝇叮咬次数以及厩螫蝇保持机械传染性的时间长度，进一步阐明了厩螫蝇在无形体病机械传播中的作用。从急性感染的犊牛向易感的脾切除犊牛传播无形体病，只需10次厩螫蝇叮咬即可完成。这些苍蝇在从急性感染的犊牛获取部分血餐后，至少在2小时内仍保持机械传染性。这些数据强调了厩螫蝇在无形体病机械传播中的效率，并表明相对较短距离的屏障可能不足以防止感染和未感染畜群之间的传播。
