Abstract
ABSTRACT:
The aim of the study was to study the occurrence of anaplasmosis in bovines in
certain parts of Coastal Andhra Pradesh, to record the clinical signs and haematobiochemical
changes in bovine anaplasmosis, to diagnose the bovine anaplasmosis by
blood smear examination and PCR and to assess the efficacy of therapy adopted in
bovines with anaplasmosis. The study revealed that occurrence of anaplasmosis in
bovines was 11.54 per cent. In the present study cattle were more affected than
buffaloes. The Anaplasma marginale was identified from the blood samples of the
clinical cases by PCR with an expected amplicon size of 458 bp. The most prominent
clinical signs observed in bovine anaplasmosis were inappetence, pale mucous
membranes, reduced milk yield, pyrexia, icterus, depression, brown coloured urine,
lymph node enlargement, weight loss, ectoparasite infestation, respiratory distress,
diarrhoea and bloody faeces. Haematological study showed anaemia with normal
leukogram. Serum biochemical profile revealed hike in serum total bilirubin level and
fall in albumin, calcium, phosphorus and glucose. However total protein and AST
values were within normal range. Single dose of oxytetracycline LA @ 20 mg/kg b.wt
and imidocarb dipropionate @ 3 mg/kg b.wt I/M were found to be useful in the
treatment of bovine anaplasmosis caused by A. marginale.
