ISOLATION OF Streptococcus pneumoniae FROM A PNEUMONIC BUFFALO CALF ; CASE STUDY

Abstract

Streptococcus pneumoniae infection was found in a 9 month aged buffalo calf having high fever (107° F), respiratory distress, mucopurulent nasal discharge with lateral recumbence lasting for 4 days. Ante mortem (Blood, edematous fluid) and Postmortem (eye-ball) sample was collected to conduct laboratory test for confirmation of causal agent. Actually the samples were collected for the purpose of isolation of Pasteurella multocida. The laboratory investigation revealed that the samples were bacteriologically positive & isolated organism were Streptococcus pneumoniae. It is proved that the buffalo calf infected by Streptococcus pneumoniae were subjected to death after 4 days of infection as the calf were treated by streptomycin, because the doctors treated it as gram-negative bacteria infection. This should be treated by broad-spectrum cephalosporins. It is emphasised that Streptococcus pneumonia may be considered to be and important respiratory pathogen which is responsible for death of buffalo calves and should be included in differential diagnosis of pulmonary diseases.
