The DNA fingerprint profiles and somatic serotypes of 71 Pasteurella multocida capsule serogroup B isolates, 13 capsule serogroup E isolates, and 16 somatic reference serotype strains were compared. Each of the 16 reference somatic serotypes had a unique DNA fingerprint profile with the HhaI restriction endonuclease. Fifty-four serogroup B isolates (isolated from classical cases of hemorrhagic ...

Invasive meningococcal disease is nationally reportable in Canada. In recent years, a serogroup C genotype, designated electrophoretic type 15 (ET15), has been the most frequently isolated meningococcal genotype in Canada and has caused epidemics across the country. Between August 1993 and September 1995, there were 9 cases of invasive meningococcal disease caused by a variant of this genotype,...

AIM Identification of different serogroups of Dichelobacter nodosus prevailing in the region and to understand the degree of genetic heterogeneities among the different isolates of D. nodosus. MATERIALS AND METHODS A total of 150 exudate samples of footrot lesions with a lesion score of 2-4 were collected from naturally infected sheep. The samples were screened by polymerase chain reaction (P...

In 2011, there were 241 laboratory-confirmed cases of invasive meningococcal disease (IMD) analysed by the National Neisseria Network, which represented 100% of cases notified to the National Notifiable Diseases Surveillance System. One hundred and twenty-five isolates of Neisseria meningitidis from invasive cases of meningococcal disease were available for which the phenotypes (serogroup, sero...

Meningococcal disease causes at least 500,000 cases and 50,000 deaths worldwide each year. Epidemics of meningococcal meningitis occur in many parts of the world. Serogroup A is associated with explosive epidemics with attack rates up to 500 per 100,000. An epidemic of serogroup A in the African ‘meningitis belt’, which began in 1996, has resulted in at least 300,000 cases to date and many thou...

One hundred and fourteen strains of Pasteurella multocida were isolated from different domestic animals species (cattle, buffalo, sheep, goat, pig, rabbit, dog, cat), avian species (chicken, duck, turkey) and wild animals (deer, tiger, orang utan, marmoset). The serogroups of P. multocida were determined by both conventional capsular serotyping and a multiplex PCR assay targeting specific capsu...

Neisseria meningitidis is a leading cause of bacterial meningitis and other serious infections worldwide. The epidemiological profile of N. meningitidis is highly changeable, with great differences in disease incidence and serogroup distribution. Six serogroups (namely serogroups A, B, C, W-135, X, and Y) are responsible for most cases of meningococcal disease worldwide; the epidemiological pro...
