Shigella Flexneri Serotypes: O-antigen Structure, Serotype Conversion, and Serotyping Methods

open access: yesOman Medical Journal, 2023
Shigella flexneri is the most common cause of shigellosis in developing countries. Up to now, 23 serotypes of S. flexneri have been reported. Different serotypes result from the addition of acetyl, glucosyl, or phosphatidylethanolamine groups on the O ...

To Serotype or Not To Serotype: That Is Still the Question [PDF]

open access: yesThe Journal of Infectious Diseases, 2007
In this issue of the Journal, the report by Banerjee et al. [1] on the postneonatal protective effect of a prior neonatal infection with G10P [11] rotavirus has important implications for rotavirus vaccinology. The protective efficacy of a neonatal rotavirus infection has been addressed previously by various investigators.

HUMAN ASTROVIRUS SEROTYPES [PDF]

open access: yesThe Lancet, 1982
SummaryTwo serotypes of human astroviruses are described. It is proposed that these should be called serotype 1 and serotype 2. Using antisera to these two types, 13 of 15 other community-acquired strains were able to be typed, 12 as serotype 1 and one as serotype 2.
