[Susceptibility to roxithromycin of gram-positive cocci isolated from patients with lowered immunity].
The study involved 412 strains of Gram-positive cocci isolated from throat, sputum, urine and stool of patients prepared for bone marrow transplantation at Department of Hematology. Determination of drug susceptibility was performed by disc diffusion method applying discs with roxithromycin, erythromycin, lincomycin, clindamycin and augmentin. Among strains of S. aureus, S. epidermidis and Micrococcus susceptible strains comprised respectively 48, 48 and 45%; among group A, B, C and G streptococci respectively 92 and 52%. Among 108 strains of group D Streptococci only 24% were susceptible to roxithromycin. Comparison of susceptibility of tested strains to roxithromycin and other antibiotics revealed similar susceptibility of staphylococci and streptococci to roxithromycin and erythromycin, while among staphylococci higher percentage of strains and among streptococci lower percentage was susceptible to lincomycin than to roxithromycin.
