..flexneri 2b dominating (23.2%). Of the 56 untypeable strains which showed invasive properties, 17 were serologically atypical and the remaining 39 belonged to a new serotype...

..5%), cdtA (97.5%), cdtB (97.5%), cdtC (97.5%), and wlaN (7.5%) genes was detected in C. jejuni by PCR. All C. jejuni strains but one produced cytolethal distending toxin in a HeLa cell assay...

..coli serotype reference strains. It is therefore proposed that these isolates represent a new provisional serovar of S. dysenteriae, type strain KIVI 162...

..It can be concluded that endemic strains of Shigella sonnei isolated from patients in Bangladesh are diverse in their genetic pattern...

..All the strains were clustered within a single type with four subtypes by pulsed-field gel electrophoresis while ribotyping patterns of all the strains were identical...

..In fluoroquinolone-resistant strains, double mutations (Ser83-->Leu, Asp87-->Asn or Gly) and a single mutation (Ser80-->Ile) were detected in the QRDRs of gyrA and parC, respectively...

..The aim of the present study was to determine the clonal relationships of ciprofloxacin-resistant Shigella dysenteriae type 1 strains isolated from south Asia, and S. dysenteriae 1 strains associated with epidemics in 1978, 1984 and 1994...

..All the strains harboring the 140-MDa plasmid were positive for the ipaH gene, had Congo red binding abilities, and were positive by the Sereny test, demonstrating their invasive properties...

..Furthermore, the high rate of prevalence of serotype 1c necessitates the commercial production of antibody against this subserotype to allow the determination of the actual burden of shigellosis caused by provisional serotype 1c...

..This study concluded that two different clones of atypical S. flexneri type 4 exist and strongly suggests that these are new subserotypes of S. flexneri that await further serological classification...

..9%, 82.4%, 14.7%, and 24.1%, respectively. Current conjugate vaccines should substantially reduce IPD, childhood pneumonia, and antimicrobial resistance in Bangladesh...

..A marker (open reading frame ORF8) for a filamentous phage previously thought to correspond to the pandemic genotype was found to have a poor correlation with the pandemic genotype...

..We studied 107 patients of liver diseases with percutaneous liver biopsy to assess the need and usefulness of post procedure abdominal binder, analgesics, antibiotics or blood transfusion, and safety of the procedure...

..The relative risk for preschool children compared with older persons was 8.9. Our regression model showed that these children were clinically ill, which suggests a role for preschool immunization...

..67, CI 1.05-12.83) than children living in a larger house. Counseling on avoiding crowding where a newborn is accommodated might reduce pneumonia incidence...

..The etiology and predictors of outcome differ according to the geographical region. This study was conducted with the aim of evaluating the etiology, complications, and outcome of FHF in Bangladesh...

..It should be possible now to study the gene(s) involved in invasion of P. alcalifaciens with these mutants. This investigation is another example of the usefulness of TnphoA mutagenesis in the study of bacterial virulence genes...

..This study was conducted to test the efficacy of a new cancer vaccine, composed of dendritic cells (DCs) pulsed with an interleukin-2 gene-encoded vaccinia virus tumor oncolysate (DC-IL-2VCO) in a CC-36 murine colon adenocarcinoma model...
