Background: Identifying regional types and evaluating the frequency of pneumococcal strains has become increasingly important especially in vaccination. The purpose of this study was the identification and frequency determination of our regional serotype and evaluation of the performance of recent type specific multiplex PCR for the diagnosis of streptococcus pneumonia serotypes. Methods: All ...

  Background: Group B Streptococci (GBS) or Streptococcus agalactiae is one of the most common causes of sepsis and meningitis in neonates and of invasive diseases in pregnant women. It can also cause infectious disease among adults with underlying medical conditions like immunocompromised individuals. Polysaccharide capsule is an important virulence factor. Nine GBS serotypes (Ia, Ib, II to VI...

This study presents serogroup 6 isolates from invasive pneumococcal disease (IPD) before and after the recommendation for childhood pneumococcal conjugate vaccination in Germany (July 2006). A total of 19,299 (children: 3508, adults: 15,791) isolates were serotyped. Serogroup 6 isolates accounted for 9.5% (children) and 6.7% (adults), respectively. 548 isolates had serotype 6A, 558 had serotype...

the study was conducted to determine the type, frequency and severity of gross, histopathologic changes, effect of route of infection and also, tissue tropism of serotype 793/b (4/91) infectious bronchitis virus. 20 day-old specific pathogen free chicks were inoculated intra-tracheally and intra-orally with 793/b serotype and lesions studied histopathologically at interval up to 10 days post-in...

Salmonella enterica serotype Typhi is a strictly human adapted pathogen that does not cause disease in nonprimate vertebrate hosts, while Salmonella enterica serotype Typhimurium is a broad-host-range pathogen. Serotype Typhi lacks some of the proteins (effectors) exported by the invasion-associated type III secretion system that are required by serotype Typhimurium for eliciting fluid secretio...

The serotypes of 144 strains of Shigella flexneri serotype 1 (serotypes 1a, 1b, and 1c) isolated from patients attending the Dhaka treatment center of the International Centre for Diarrhoeal Disease Research, Bangladesh, between 1997 and 2001 were serologically confirmed by using commercially available antisera and a panel of monoclonal antibodies specific for S. flexneri group and type factor ...

BACKGROUND In 2007, Park et al. identified a novel serotype among Streptococcus pneumoniae serogroup 6 which they named serotype 6C. The aim of this study was to evaluate with the Neufeld test a novel S. pneumoniae serotype 6C type specific polyclonal antiserum. In addition, serotype 6C isolates found in Denmark in 2007 and 2008 as well as eight old original serotype 6A isolates were characteri...

Australia has a universal infant pneumococcal conjugate vaccination program and until recently polysaccharide vaccine for non-Indigenous adults aged ?65 years Indigenous ?50 years. We documented the impacts of adult programs on epidemiology invasive disease (IPD) in adults. IPD notifications from National Notifiable Disease Surveillance System were analysed 2002 to 2017, grouped by age, serotyp...

The calcineurin gene was cloned and disrupted in serotype D strains of Cryptococcus neoformans. Serotype A and serotype D calcineurin mutants were inviable at 37 degrees C and avirulent in mice, whereas only serotype A mutants were cation stress sensitive. Thus, calcineurin plays conserved and divergent roles in serotype A and serotype D strains.
