A coagglutination test for the identification and serotyping of Haemophilus pleuropneumoniae is described. A total of 360 H. pleuropneumoniae strains were isolated from pulmonary tissues of feeder pigs which died of acute pleuropneumonia. All of the isolates were serotyped by coagglutination, and the results were confirmed by the ring precipitation test. The most common serotype isolated in Que...

Two hundred seven Streptococcus pneumoniae isolates were obtained from patients admitted to Siriraj Hospital. One hundred two, and 105 isolates were from sterile sites and non-sterile sites, respectively. They were serotyped by Quellung reaction with specific antisera from Statens Serum Institut; 81.6% of these pneumococci were typeable. These serotypes were included in the 23-valent pneumococc...

Multilocus sequence typing (MLST) was applied to all unique serotype 6C and 6D isolates and a random selection of serotype 6B and 6A isolates from nasopharyngeal swabs from Fijian children enrolled in a recent vaccine trial. The results suggest that Fijian serotype 6D has arisen independently from both serotypes 6A/C and 6B.

A total of 91 of 1,480 invasive isolates (6.1%) collected from adults in Barcelona, Spain, in the period of 1994 to 2008 were of serogroup 6 (6B, 47 isolates; 6A, 28; and 6C, 16). Throughout this period, serotype 6B (Spain(6B)-ST90) decreased, and serotype 6A remained stable. An increase in serotype 6C (ST224) in the 2004-2008 period was observed.

Enteric fever is endemic in India. Usually caused by Salmonella enterica serotype Typhi and S. enterica serotype Paratyphi A. Enteric fever due to non-typhoidal Salmonellae is rare. We report an extremely rare case of enteric fever caused by S. enterica serotype Weltevreden in an HIV-positive 27-year-old male.

Outbreaks associated with distinct strains of Salmonella enterica serotype Uganda, a rare serotype, occurred in New York City and Chicago during the summer of 2001. Both outbreaks were linked to eating ready-to-eat pork products. This serotype may emerge as a more frequent cause of human infections.

Recent studies have reported the isolation of highly mucoid serotype 3 Streptococcus pneumoniae (Sp) from the respiratory tracts of children with cystic fibrosis (CF). Whether these highly mucoid Sp contribute to, or are associated with, respiratory failure among patients with CF remains unknown. Other mucoid bacteria, predominately Pseudomonas aeruginosa, are associated with CF respiratory dec...

Group B Neisseria meningitidis has been subdivided into 11 distinct serotypes by a sensitive bactericidal inhibition technique. The antigens responsible for induction of bactericidal type-specific antibodies were found to be extractable from the group B cells with heating at 100 C either by 0.017 n HCl in saline or by normal saline. These extracted serotype antigens were detected by a capillary...

From December 2002 to June 2003, 14 cultures of Salmonella enterica serotype Babelsberg and 6 cultures of serotype Enteritidis, isolated in France from internationally adopted children, were identified at the French National Reference Center for Salmonella. All serotype Babelsberg isolates were related, as determined by pulsed-field gel electrophoresis, and all serotype Enteritidis strains disp...

Bovine rotaviruses isolated from beef and dairy herds in Argentina were serotyped by the immunoperoxidase focus reduction assay as previously described (G. Gerna, M. Battaglia, G. Milenesi, N. Passarani, E. Percivalle, and E. Cattaneo, Infect. Immun. 43:722-729, 1984). Three strains from beef herds were related to the UK and NCDV bovine rotavirus strains defined as serotype 6 (Y. Hoshino, R. G....
