Abstract

Anaplasma marginale carrier infection was eliminated from 10 cattle in the USA by oral chlortetracycline at 0.5 mg/lb body-weight daily for 120 days. The complement fixation test was negative in all the treated animals 180 days after treatment ended and infection was not transmitted by subinoculation into susceptible animals 28 and 180 days later. 180 days after treatment, the treated animals were highly resistant to challenge with an infective dose of A. marginale carrier blood.
