ABSTRACT
The anti microbial activities of three commonly
used disinfectants Septol, Dettol and Z-germicides against Escherichia coli,
Staphylococcus aureus and Candida a/bicans were investigated. Their efficacy
was determined using the agar diffusion method at different concentrations of
the test disinfectants and their potency was tested against a standard (phenol)
by using phenol coefficient tests. The use of Septol on E.coli and S.aureus
showed weak bactericidal efficacy with a zone of inhibition of 30mm and 29mm at
1 00% concentrations as compared with the others, even at their in use
dilutions, although it posses a high efficacy on C.albicans with a zone of
inhibition of 75mm. Dettol and Z-germicides had equal inhibitory effects of
45mm on E.coli and S.aureus at 100% concentrations but Dettol was more
effective, even at the in use dilutions as compared to Zgermicides, although
S.aureus was observed to be the most susceptible to Z-germicides when used in
higher concentrations. It was observed that as the concentration reduces, the
susceptibility rates of the test organisms increases. The potency of the
disinfectants against a standard disinfectant (phenol) showed that they were
all effective than phenol with Dettol being the most potent/effective
disinfectant as compared with Z-germicide and Septol. To ensure disinfectants
efficacy, test should be carried out on new disinfectant products and also
further studies should be carried out about disinfectants.
