Direct detection and characterization of foot-and-mouth disease virus in East Africa using a field-ready real-time PCR platform [PDF]

, 2017
Effective control and monitoring of foot-and-mouth disease (FMD) relies upon rapid and accurate disease confirmation. Currently, clinical samples are usually tested in reference laboratories using standardized assays recommended by The World Organisation

New Pneumococcal Serotype 15D

Journal of Clinical Microbiology, 2021
The pneumococcal serogroup 15 comprises four capsular polysaccharide serotypes (15A, 15B, 15C, 15F) that collectively account for an impactful disease burden ([1][1], [2][2]). These four serotypes are defined by Quellung reaction typing, employing specific serologic factor sera to visualize ...

Serotypes of bovine astrovirus [PDF]

Journal of Clinical Microbiology, 1985
Three isolates of bovine astrovirus, one from the United Kingdom and two from the United States, possessed common antigens by immunofluorescence and strain-specific antigens by neutralization and were designated as two, and probably three, distinct serotypes.

Increased pathogenicity of pneumococcal serotype 1 is driven by rapid autolysis and release of pneumolysin [PDF]

, 2020
Streptococcus pneumoniae serotype 1 is the predominant cause of invasive pneumococcal disease in sub-Saharan Africa, but the mechanism behind its increased invasiveness is not well understood.

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

FEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...
