The use of an indirect immunofluorescence technique demonstrated that serum from reindeer, Rangifer tarandus tarandus, infected with Elaphostrongylus rangiferi (Nematoda, Metastrongyloidea) contained antibodies directed against antigen(s) on the cuticle of the parasites first-stage larvae (L1). Output of L1 from the male reindeer was low in the period June to August, but increased to a higher level during the rutting season (September to October). The titre of specific antibody showed an inverse pattern. In the female reindeer, larval output remained high throughout the sampling period from January to July. During this period antibody titre was low. A relationship between stress (rutting season or calving period), immunity and larval output is suggested.
间接免疫荧光技术的应用表明，感染了驯鹿原圆线虫（线虫纲，后圆线虫总科）的驯鹿（Rangifer tarandus tarandus）血清中含有针对该寄生虫第一期幼虫（L1）角质层上抗原的抗体。雄性驯鹿在6月至8月期间L1的产出量较低，但在发情季节（9月至10月）增加到较高水平。特异性抗体的滴度呈现相反的模式。在雌性驯鹿中，从1月至7月的整个采样期间幼虫产出量一直很高。在此期间抗体滴度较低。研究表明应激（发情季节或产犊期）、免疫力和幼虫产出量之间存在关联。
