Haemolytic Activity And Streptomycin Susceptibility Profile Of Bacterial Isolates Associated With Nasal Secretion
ABSTRACT
Human nasal cavity host major human pathogens which exhibit different haemolytic activities. This study was conducted to determine haemolytic activity and streptomycin susceptibility profile of bacterial isolates associated with nasal secretion. A total of 186 nasal samples (swabs) were collected from both male and female in different age groups in Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria. The samples were analysed using culture techniques, Gram staining, biochemical test and antimicirobial susceptibility testing. Findings from the study revealed that 163 bacteria belonging to different genera and species were isolated. The bacterial isolates included Bacillus (36.20%), coagulase negative Staphylococcus (29.20%), Streptotococcus other than Streptococcus agalactiae (18.40%), coagulase positive Staphylococcus (14.11%) and Streptococcus agalactiae (1.84%). However, bacterial isolates found on blood agar cultured plates showed different haemolytic patterns including alpha, beta and gamma haemolysis. Both Bacillus spp and Streptococcus agalactiae showed beta- haemolysis while coagulase negative Staphylococcus revealed gamma haemolysis. When tested to Streptomycin, Streptococcus organisms showed highest susceptibility followed by Bacillus and the least was coagulase negative Staphylococcus.
