Emergence of the M Phenotype of Erythromycin-Resistant Pneumococci in South Africa
|Years||Total isolatesb||No. of E-R strains (%)c||No. of M strains (% of E-R strains)|
|1987-1991||5,115||128 (2.5)||1 (0.8)|
|1992-1996||4,753||142 (3.0)||28 (19.7)|
|Total||9,868||270 (2.7)||29 (10.7)|
aOf 9,868 blood and cerebrospinal fluid (CSF) isolates received by the SAIMR from 1987 to 1996, 270 were fully resistant to erythromycin. While the number of erythromycin-resistant blood and CSF isolates received increased from 1987 to 1991 compared with 1992 to 1996 (2.5% to 3.0%), the increase was not significant. There was no significant relationship between erythromycin resistance and the M phenotype within any given province throughout the 10 years.
