Gonorrhoea: Signs, Symptoms and Serogroups

International Journal of STD & AIDS, 1992
Over 19 weeks, 104 male patients attending a genitourinary medicine clinic with gonococcal urethritis were asked to complete a questionnaire detailing symptoms. Sixty-seven questionnaires were duly completed. The examining nurse documented signs.

Proposal for a fourth aquabirnavirus serogroup

Archives of Virology, 2008
Four putative aquabirnaviruses, based on morphology, nucleic acid type and partial RNA-dependent RNA polymerase gene (VP1) sequence, isolated from three tropical freshwater fish species were not neutralised by antisera against type members of the Aquabirnavirus genus serogroups A, B or C.

Capsule switching of Neisseria meningitidis sequence type 7 serogroup A to serogroup X

Journal of Infection, 2017
The bacterial pathogen Neisseria meningitidis is able to escape the currently available capsule-based vaccines by undergoing capsule switching. In this study, we investigated whether capsule switching has occurred in a recently emerged sequence type (ST) 7 serogroup X isolate in China, for which currently no vaccine is available.To identify capsule ...

Serogroup conversion of Vibrio cholerae

Canadian Journal of Microbiology, 1995
Vibrio cholerae serogroup O1 can be detected in the environment in a viable but nonculturable form, whereas V. cholerae non-O1 cells can be readily cultured during interepidemic periods in geographical regions where cholera is endemic. In the present study, pure cultures of V.

Mapping phosphoproteins in Neisseria meningitidis serogroup A

PROTEOMICS, 2011
AbstractTo investigate the phosphorylation capability of serogroup A Neisseria meningitidis (MenA) and to implement our knowledge in meningococcal biology and in bacterial post‐translational modifications, cell extracts were separated by 2‐DE and 51 novel phosphoproteins were revealed by the use of the highly specific Ser/Thr/Tyr‐phosphorylated ...

A clonal analysis of Neisseria meningitidis serogroup A

Antonie van Leeuwenhoek, 1987
A typing scheme has recently been developed for Neisseria meningitidis serogroup A based on the clonal population structure of these bacteria. An international strain collection consisting of 423 group A strains isolated from 23 epidemics or outbreaks since 1963, as well as from older epidemics and numerous non-epidemic situations was used in the ...

A new serogroup (L) of Neisseria meningitidis

Journal of Clinical Microbiology, 1983
A strain of neisseria meningitidis (LCDC 78189) isolated from the mother of a 3-year-old male with meningococcal meningitis was found to be antigenically distinct from the known serogroups A, B, C, D, H, I, K, X, Y, Z, 29E, and W135; it was designated serogroup L.

Plasmids and serogroups in Campylobacter jejuni

APMIS, 1989
For epidemiological purposes identification of Campylobacter strains is usually based on surface antigen characteristics. Two different systems, one for heat‐stable (HS) and one for heat‐labile (HL) antigen have dominated. In earlier studies we found a great variability in the two antigen systems. The aim of the present investigation was to analyse the

Serogrouping of Bacteroides vulgatus by the agglutination test [PDF]

Journal of Clinical Microbiology, 1985
The agglutination technique was used to establish a serological classification scheme for Bacteroides vulgatus strains isolated from normal human feces and clinical specimens, especially from ulcerative colitis patients. Absorbed antisera to 10 strains of B. vulgatus were prepared. These 10 absorbed antisera were species specific. Of 90 B.
