ABSTRACT
Antiseptics and Disinfectants are chemicals used extensively in hospitals, other health care centres and in homes to control the growth of microorganisms on living tissues and inanimate objects respectively. This study compared the efficacy of two disinfectants (HYPO and Ivy) and two antiseptics (Iodine and Carex sanitizer) against Staphylococcus aureus and Pseudomonas aeruginosa .The disk diffusion method and Rideal Walker Phenol coefficient test were used. For the antiseptics , Staphylococcus aureus was susceptible to Iodine(18) and was not susceptible to Carex sanitizer. For the test disinfectants, Staphylococcus aureus was less susceptible to Ivy (24) and more susceptible Hypo . For the antiseptics against Pseudomonas aeruginosa, it was more susceptible to Iodine and less susceptible to Carex sanitizer. The disinfectants against Pseudomonas aeruginosa, Pseudomonas aeruginosa was more susceptible to Hypo and was resistant to Ivy. The phenol coefficient of the test antiseptics against Staphylococcus aureus ranged from 5-6 . Carex sanitizer had the highest with 6. While Iodine had the least with 5.for the test disinfectants the phenol coefficient ranged from 6-7. Ivy had the least with 6 while Hypo had the highest with 7.For Pseudomonas aeruginosa , the phenol coefficient of the test antiseptics ranged from 5.3 to 6.3.Iodine had the least with 5.3 while Carex sanitizer had the highest with 6.3.For the test disinfectants, the phenol coefficient was 7.4 for both Hypo and Ivy. Thus for the phenol coefficient test, all the disinfectants and antiseptics showed strong bactericidal effect against the organisms. While for the disk diffusion, the result showed that Hypo had the strongest bactericidal effect while Carex sanitizer had the least bactericidal effect .The study concluded that Hypo should be used in our daily disinfection.
