متن کاملGenetic linkage of exotoxin alleles and emm gene markers for tissue tropism in group A streptococci.
In group A streptococci, genetic markers for principal tissue reservoir are located within emm genes, which encode surface proteins that have a role in virulence. A worldwide collection of 160 isolates was evaluated for two traits: chromosomal emm gene markers for tissue tropism (designated patterns A-E), and bacteriophage-associated genes (speA and speC) encoding pyrogenic exotoxins. The speA ...
متن کاملM protein gene (emm type) analysis of group A beta-hemolytic streptococci from Ethiopia reveals unique patterns.
The genetic diversity of group A streptococcal (GAS) isolates obtained in 1990 from Ethiopian children with various streptococcal diseases was studied by using emm gene sequence analysis. A total of 217 GAS isolates were included: 155 and 62 isolates from throat and skin, respectively. A total of 78 different emm/st types were detected among the 217 isolates. Of these, 166 (76.5%) belonged to 5...
متن کاملAntibiotic resistance pattern of group-a beta-hemolytic streptococci isolated from north Indian children.
BACKGROUND The current resistance pattern of GABHS (group-A beta-hemolytic streptococci) in India has not been discussed. AIM To fill the above-mentioned void, we planned this study to determine the prevalence and degree of antibacterial resistance in GABHS isolates. SETTINGS AND DESIGN Children with acute pharyngo-tonsillitis who had not received antibiotic in the preceding week, attending...
متن کاملGroup B beta-hemolytic streptococci causing pharyngitis.
Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B ...
