Stuen S Bergstrom K The effect of two different oxytetracycline treatments in experimental Ehrlichiaphagocytophila infected lambs Acta vet. scand. 2001 42 339346. - The effect of 2 different oxytetracycline treatments in acute E. phagocytophila infected lambs was investigated. Twenty 5-month-old lambs of the Dala and Rygja breeds were used. Ten lambs were inoculated intravenously with a stabilate of an ovine E. phagocytophila strain. On the third day of fever 4 lambs were given long-acting oxytetracycline Terramycin prolongatum vet Pfizer 20 mg kg intramuscularly and another 4 lambs were given short-acting oxytetracycline Terramycin vet Pfizer 10 mg kg intravenously for 5 consecutive days. The lambs were examined for the presence of Ehrlichia infection by blood smear evaluation polymerase chain reaction PCR and antibody titre against E. equi. One month after the last antibiotic treatment 250 ml citrate blood from each of these lambs were inoculated into each of 10 susceptible lambs which were observed during the following 6 weeks. The results indicate that oxytetracycline given in the acute stage of the infection may effectively teminate the development of fever rickettsemia and weight reduction in E. phagocytophila infected lambs. No difference was observed between the 2 treatment groups. However at least 3 of 8 antibiotic treated lambs 37.5 were still infected with granulocytic Ehrlichia 3 months after treatment. sheep antibodies Ehrlichia equi persistence tick-borne fever.
