Rotavirus VP7 serotypes were identified in stools from 72.9% (1,302/1,784) of hospitalized Australian children in six cities (1989 to 1992) and comprised 1,088 (83.6%) serotype G1 isolates, 84 (6.4%) serotype G2 isolates, 64 (4.9%) serotype G3 isolates, 49 (3.8%) serotype G4 isolates, and 17 (1.3%) isolates of mixed serotypes. The most densely populated cities yielded the greatest diversity of ...

BACKGROUND In December 2001, a fatal case of pneumococcal meningitis in a Marine Corps recruit was identified. As pneumococcal vaccine usage in recruit populations is being considered, an investigation was initiated into the causative serotype. CASE PRESENTATION Traditional and molecular methods were utilized to determine the serotype of the infecting pneumococcus. The pneumococcal isolate wa...

•Serotype 19A but not 3 declines in mucosal infections after introduction of PCV13.•Serotype remains present and may reemerge pediatric IPD if PCV13 is halted.•Respiratory invasive are caused by different nonvaccine serotypes.•Certain replacement serotypes associated with important antimicrobial resistance. ObjectiveTo determine the serotype distribution resistance Streptococcus pneumoniae pati...

BACKGROUND Public Health England (PHE) holds a collection of Shigella flexneri Type strains isolated between 1949 and 1972 representing 15 established serotypes and one provisional type, E1037. In this study, the genomes of all 16 PHE Type strains were sequenced using the Illumina HiSeq platform. The relationship between core genome phylogeny and serotype was examined. RESULTS The most common...

Thirty-three strains of Cryptococcus neoformans were isolated from clinical specimens, including specimens from AIDS patients in Brazil, and were classified into two serotypes; we detected 31 and 2 strains of serotypes A and B, respectively. Random amplified polymorphic DNA (RAPD) fingerprint pattern analyses of these strains of serotypes A and B showed that the patterns were similar for strain...

Streptococcus suis strains (n=411), isolated from diseased pigs in seven European countries were serotyped using specific antisera against serotype 1 to 28, and were phenotyped on the basis of their muramidase-released-protein (MRP) and extracellular-factor protein (EF) production. Overall, S. suis serotype 2 appeared to be most prevalent (32%), followed by serotype 9 (20%) and serotype 1 (12%)...

The oral bacterium Actinobacillus actinomycetemcomitans is implicated as a causative agent of localized juvenile periodontitis (LJP). A. actinomycetemcomitans is classified into five serotypes (a to e) corresponding to five structurally and antigenically distinct O polysaccharide (O-PS) components of their respective lipopolysaccharide molecules. Serotype b has been reported to be the dominant ...
