The feasibility of immunizing calves against Hypoderma lineatum and H. bovis with a crude H. lineatum larval extract or culture-derived antigen was investigated. Larval survival was followed through pupation. Grub appearance in the backs of both of the immunized groups was found to be 50% of that in the control groups. First appearance of H. bovis was significantly retarded in both immunized groups; however, H. lineatum was unaffected. Duration of H. bovis dropping was also shorter in animals receiving crude extract than in controls while duration of dropping of H. lineatum was not influenced by immunization. Survival of H. lineatum larvae to pupation was significantly reduced in animals immunized with crude larval extract, but not in those receiving culture-derived antigen. H. bovis survival was reduced by both treatments.
研究了用粗制的纹皮蝇幼虫提取物或培养衍生抗原来免疫犊牛抵抗纹皮蝇和牛皮蝇的可行性。观察幼虫直至化蛹的存活情况。发现两个免疫组牛背部的蛆虫出现率为对照组的50%。在两个免疫组中，牛皮蝇的首次出现明显延迟；然而，纹皮蝇不受影响。接受粗提物的动物中牛皮蝇掉落的持续时间也比对照组短，而纹皮蝇掉落的持续时间不受免疫影响。用粗制幼虫提取物免疫的动物中，纹皮蝇幼虫存活至化蛹的比例显著降低，但接受培养衍生抗原的动物中没有这种情况。两种处理均降低了牛皮蝇的存活率。
