Different erythromycin resistance mechanisms in group C and group G streptococci.
Different mechanisms of erythromycin resistance predominate in group C and G streptococcus (GCS and GGS, respectively) isolates collected from 1992 to 1995 in Finland. Of the 21 erythromycin-resistant GCS and 32 erythromycin-resistant GGS isolates, 95% had the mefA or mefE drug efflux gene and 94% had the ermTR methylase gene, respectively.
متن کاملGenotyping of erythromycin resistant group C & G streptococci isolated in Chennai, south India
BACKGROUND & OBJECTIVES Increasing resistance to erythromycin has been observed worldwide in group C and group G streptococci (GCS/GGS). The information available from India is scanty. The aim of the study was to identify erythromycin resistant GCS/GGS isolates in Chennai, south India, and to compare erythromycin resistant genotypes with emm types. METHODS One hundred and thirty one GCS/GGS i...
متن کاملErythromycin-resistant group A streptococci in schoolchildren in Pittsburgh.
BACKGROUND Resistance to erythromycin has been very uncommon among group A streptococci in the United States. METHODS As part of a longitudinal study, we obtained surveillance throat cultures twice monthly and with each new respiratory tract illness from children in kindergarten through grade 8 at one school in Pittsburgh. Screening for resistance to erythromycin and clindamycin was initially...
متن کاملLectins detecting group C streptococci.
Lectin of Wisteria floribunda specifically agglutinates group C streptococci. The reaction is strongly inhibited by N-acetyl-d-galactosamine, slightly by lactose, and not at all by galactose. The utility of the simple test of the lectin with group C streptococci is discussed.
متن کاملErythromycin and penicillin resistance mechanisms among viridans group streptococci isolated from blood cultures of adult patients with underlying diseases.
The aim of the study was to evaluate the species distribution, antimicrobial susceptibility and erythromycin-penicillin resistance mechanisms of viridans streptococci (VGS) isolates from blood cultures of adult patients with underlying diseases. Fifty VGS blood culture isolates were screened for their antibiotic susceptibilities against penicillin G, erythromycin and tetracycline by E-test. Cli...
