Molecular characterization of extraintestinal and diarrheagenic Escherichia coli blood isolates

Virulence, 2022
Pathogenic E. coli strains can be classified into two major groups, based on the presence of specific virulence factors: extraintestinal pathogenic E. coli (ExPEC) and diarrheagenic E. coli (DEC).

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

Oman 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-antigen backbone and horizontal transfer of mentioned groups can lead to serotype conversion among S ...

High concordance of ELISA and neutralization assays allows for the detection of antibodies to individual AAV serotypes

Molecular Therapy: Methods & Clinical Development, 2022
Prescreening of participants in clinical trials that use adeno-associated virus (AAV) vectors is required to identify naive participants, as preexisting neutralizing antibodies can limit the efficacy of AAV gene therapies.

Horizontal Gene Transfer and Loss of Serotype-Specific Genes in Listeria monocytogenes Can Lead to Incorrect Serotype Designations with a Commonly-Employed Molecular Serotyping Scheme

Microbiology Spectrum, 2023
Listeria monocytogenes is a Gram-positive, facultative intracellular foodborne pathogen capable of causing severe, invasive illness (listeriosis). Three serotypes, 1/2a, 1/2b, and 4b, are leading contributors to human listeriosis, with 4b including the ...

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

The 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]

The 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.
