Genetic 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 ...

Genetic Diversity and Exotoxin A Production of Group A Streptococci Causing Sepsis

The M protein and streptococcus pyrogenic exotoxin (SPE A) are important virulence factors in group A streptococci (GAS) infections. The emm types of GAS strains isolated from patients with sepsis were determined by sequencing the 5' N-terminus of the emm gene, encoding the M protein, and clonality analysis using pulsed-field gel electrophoresis. The presence of speA and production of SPE A wer...

Genetic variation in group A streptococci.

Group A streptococcus (GAS) is responsible for a range of human diseases that vary in their clinical manifestations and severity. While numerous virulence factors have been described, the way these factors interact to promote different streptococcal diseases is less clear. In order to identify multifactorial relationships between GAS and the human host, novel high-throughput techniques such as ...

Linkage Data for Group V Markers in Neurospora.

paper presents linkage data from crosses with markers in linkage group Ty", Neurospora cicrssa (Group E of HOULAHAN, BEADLE and CALHOUN 1949). Several new markers are reported, and the map relations of a number of other genes are clarified. Many of these data were obtained in the course of an investigation of interference ( STRICKLAND unpublished). Certain of the new markers are in positions wh...
