Evolutionary genetics of the capsular locus of serogroup 6 pneumococci.
The evolution of the capsular biosynthetic (cps) locus of serogroup 6 Streptococcus pneumoniae was investigated by analyzing sequence variation within three serotype-specific cps genes from 102 serotype 6A and 6B isolates. Sequence variation within these cps genes was related to the genetic relatedness of the isolates, determined by multilocus sequence typing, and to the inferred patterns of re...
متن کاملEvolution of the capsular gene locus of Streptococcus pneumoniae serogroup 6
Streptococcus pneumoniae expressing serogroup 6 capsules frequently causes pneumococcal infections and the evolutionary origins of the serogroup 6 strains have been extensively studied. However, these studies were performed when serogroup 6 had only two known members (serotypes 6A and 6B) and before the two new members (serotypes 6C and 6D) expressing wciN(β) were found. We have therefore reinv...
متن کاملPneumococci of More Than One Capsular Type
Monoclonal antibodies against pneumococcal surface protein A (PspA) have been shown to protect mice from fatal pneumococcal infection. PspA is highly variable serologically, raising the possibility that PspA from one strain might not be able to elicit protective responses against strains which possess serologically different PspA. We have prepared a Agtll library of pneumococcal genomic DNA and...
متن کاملthe relationship between locus of control and iranian efl university students’ beliefs about language learning
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
