Campylobacter jejuni abortion in a heifer.
Campylobacter jejuni was isolated from the lung and stomach contents of an aborted bovine fetus. The bacterial isolate was classified according to morphologic, biochemical, and thermotolerance characteristics as well as sensitivity to antibiotics and biochemical agents. Serotyping was specific for C jejuni and excluded this isolate from the more common bovine causes of campylobacteriosis, C fetus subsp venerealis or C fetus subsp fetus. This report stresses the need for careful speciation of all Campylobacter isolates from aborted fetuses, especially in conditions where routine vaccination has not reduced abortion rates in the herd. Campylobacter jejuni is much more prevalent in causing human infections than is C fetus subsp venerealis or C fetus subsp fetus. Therefore, from a public health standpoint identification is important.
