Staphylococci are Gram positive bacteria capable of causing both localize and life-threatening systemic infections in animals and humans. The present study was aimed at the isolation and identification of various Staphylococci species from cattle in Maiduguri Borno State. One hundred (100) nasal swabs were randomly collected from cattle in January 2011, and then processed in accordance with standard methods for bacteria isolation. Colony morphology, assessment on manitol salt agar (MSA), coagulase, catalase and haemolytic tests were among the standard bacteriological methods used in the identification and biochemical characterization of Staphylococci species. Isolates were then subjected to an in-vitro antimicrobial susceptibility testing using the disc diffusion method. 92 bacterial isolates were obtained, 21 of the isolates were identified as coagulase- positive Staphylococcus aureus, 49 as coagulase - negative Staphylococci, while 22 isolates were identified as micrococci. All the Staphylococcus aureus isolates were positive for mannitol fermentation test and produced beta- heamolysis on blood agar containing 5% sheep erythrocytes. Staphylococci species were most susceptible to ciprofloxacin (100%) and ceftrazole (90.5%). In conclusion, this study indicates the occurrence of coagulase positive and negative Staphylococci in Bovine nasal mucosa in the study area thus suggest ciprofloxacin and ceftrazole as drug of choice in the treatment of infections and diseases caused by staphylococcus.
