Abstract

The interactions between Ostertagia ostertagi and Cooperia oncophora were studied in calves by concurrent and sequential infections. A reciprocal negative interaction between the 2 species was found in sequential, but not in concurrent infections. This result was supported by the finding of serological cross-reactions. It is suggested that the negative interaction is immunologically mediated. The depression of weight gain found after infection was similar for O. ostertagi- and C. oncophora-infected calves.

摘要

通过同时感染和序贯感染的方式，对犊牛体内奥斯特他线虫（Ostertagia ostertagi）和牛库珀线虫（Cooperia oncophora）之间的相互作用进行了研究。在序贯感染中发现这两种线虫之间存在相互的负性作用，但在同时感染中未发现。血清学交叉反应的结果支持了这一发现。提示这种负性作用是由免疫介导的。奥斯特他线虫感染和牛库珀线虫感染的犊牛在感染后体重增加的降低情况相似。
