Haemolysin production and serum resistance ability of bacteria isolates from blood culture were investigated using standard microbiological technique. Enterobactor
species were the bacteria isolates with the highest prevalence of β-haemolysin production while klebsiella
species were the least. No strain of Citrobacter freundii
, Proteus vulgaris
species and coagulase negative Staphylococcus
produced haemolysis. No bacteria species was sensitive to the bactericidal action of normal human serum. There was no association between haemolysin production and resistance to ciprofloxacin, ceftriaxone and ceftazidime. Conclusively, bacteria agents of septicemia are very virulence and urgent treatment is advocated to stem the tile of associated sequelae.
