Title: Antigenic Characteristics of Vibrio Fetus
Author: Ingram, Donald George
Abstract: Vibrio fetus infection has become recognised as one of the principal infectious causes of reduced reproductive efficiency in cattle and sheep. The disease is manifest in cattle by infertility, abortion and sterility. Serious losses in herds are caused by the reduced milk yield and decreased calf crop. After the initial onset of the disease in a herd, undetected early abortions, apparent failure to conceive from three or more services and off-cycle return to estrus usually causes greater economic losses than detected abortions. The purpose of this paper is to describe the results of research on the antigenic structure of various strains of vibrio fetus and to compare the antibody response in bovine and rabbit sera produced by intravenous and subcutaneous inoculation.
