In spite of the rapid development of antibiotics Staphylococcus aureus has still been causing various nosocomial infections in many countries including Korea, while in advanced countries the opportunist, Pseudomonas aeruginosa replacing its notorious role.
In the present study a survey on the antibiotic resistance pattern in the most recently isolated Staphylococcus aureus was carried out, and the results obtained were as follows.
Seventy-eight strains of Staphylococcus aureus from patients (Chonnam University Medical School Hospital, 1981 March-July) and forty-three from air(1 hour exposure at various places of the Hospital, 1981 July 7, 2 P.M.) were isolated and MICs of CP, CM, GM, TC, PC, EM, MT and SB were measured against each of the organisms.
All of strains submitted were very susceptible to the action of CP, while being most resistant to PC. The distribution patterns of MIC were more or less similiar in GM, TC, PC, EM and MT against air-isolated cells, while like phenomena observed in GM, TC, PC and EM against patient-isolated ones.
When the rate of resistance, which was determined by a certain level of MIC, was compared between the two groups, TC-resistance was particularly high in patient-isolated strains, next PC, EM, GM and CM ´in the order of resistance difference. Against MT and SB, however, air-isolated organisms sshowed the tendency of higher resistance than patient-isolated ones.
