We report here the complete genome sequences of two of the earliest known strains of Legionella pneumophila subsp. fraseri Detroit-1 is serogroup 1 and was isolated from a lung biopsy specimen in 1977. Dallas 1E is serogroup 5 and was isolated in 1978 from a cooling tower.

We describe two serogroup O157 Escherichia coli strains from Brazilian infants with diarrhea. A variety of assays indicate that these strains belong to the enteropathogenic, not the enterohemorrhagic, pathotype. These strains possess a novel bfpA allele encoding the type IV pilin characteristic of typical enteropathogenic E. coli strains. Our results emphasize the pitfalls of classifying pathog...

Serogroup A Neisseria meningitidis has repeatedly caused widespread epidemics of meningitis and septicemia throughout the 20th century. Recently, in a limited collection of strains, epidemic serogroup A isolates were found to have elevated mutation rates that was caused by defects in mismatch repair pathways. To ascertain the role of these mutators in the epidemic spread of this serogroup, the ...

BACKGROUND Finnish and Swedish waste water systems used by the forest industry were found to be exceptionally heavily contaminated with legionellae in 2005. CASE PRESENTATION We report two cases of severe pneumonia in employees working at two separate mills in Finland in 2006. Legionella serological and urinary antigen tests were used to diagnose Legionnaires' disease in the symptomatic emplo...

Current serotyping methods classify Pasteurella multocida into five capsular serogroups (serogroups A, B, D, E, and F) and 16 somatic serotypes (serotypes 1 to 16). In the present study, we have developed a multiplex PCR assay as a rapid alternative to the conventional capsular serotyping system. The serogroup-specific primers used in this assay were designed following identification, sequence ...

This paper describes a sudden increase of meningococcal notifications in the Australian Capital Territory within a 3 month period, and the public health strategies used to manage it. There were 15 cases of meningococcal disease notified to the Communicable Disease Control (CDC) section, Australian Capital Territory Health (ACT Health), between 6 November 2003 and 5 February 2004. This was much ...

background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...

Legionella pneumophila is the leading etiology of legionellosis infections in North America and Europe. Here we report the draft genome sequence of L. pneumophila D-5864, a serogroup 6 strain, which was isolated from a bronchial alveolar lavage specimen of a male patient from Arizona in 2009. Genes within the lipopolysaccharide (LPS)-biosynthesis region could potentially be determinants of sero...

Serogroup B Neisseria meningitidis is a frequent cause of invasive meningococcal disease, yet there are no effective vaccines suitable for routine immunisation. Limited efficacy has been shown with meningococcal outer membrane vacccines in children 4 years and older. Here we review the status of current research and consider new approaches to development of meningococcal serogroup B vaccines.
