Aerobic bacteria from nasal discharge of goats suffering from clinical PPR: isolation and identification

Abstract

Bacteriological isolation of aerobic bacteria from nasal discharge of achondroplastic West African dwarf goats showing clinical signs of peste des petits ruminants (PPR), and the laboratory procedures carried out for the identification of the isolates are described. From a total of forty nasal swabs obtained seventy five isolates were recovered. The percentage frequency of isolation of different organisms in descending order of occurrence is as follows: Staphylococcus 44.0%; Streptococcus 22.67%; Neisseria 12.00%; Pasteurella 10.67%; Pseudomonas 4.00%; Proteus 4.00% and Corynebacterium 1.33%. A further break-down using biochemical tests revealed that Staphylococcus aureus accounted for 30.67% of the total bacteria isolates; Staphylococcus epidermidis 13.33%; Streptococcus viridans 18.67%; Streptococcus pyogenes 4.00%; Neisseria catarrhalis 12.00%; Proteus mirabilis 2.67%; Proteus rettgeri 1.33%; Pseudomonas aeruginosa 5.33%; Pasteurella multocida 4.00%; Pasteurella haemolytica 6.67% and Corynebacterium pyogenes 1.33%.
