Molecular analysis of enteric viruses circulating in Tunisia : relationships between blood group antigens and rotavirus and norovirus infectivity

2015

Rotavirus and norovirus are the main aetiological agents of gastroenteritis in Tunisia. Stool specimens and saliva were collected from children younger than 6 years of age, admitted to the Fattouma Bourguiba Hospital (Monastir, Tunisia) for gastroenteritis during the winter 2011-12. Saliva analysis showed that 79% and 21% patients had secretor and non-secretor phenotypes, respectively. Group O blood type was predominant (42%) followed by groups A (30%), B (21%) and AB (7%), whilst 96% of the patients were positive for Lewis antigen. For 98 patients, blood samples were available and were used for FUT2 genotyping. 77.6% of the cohort were secretor (Se+/Se+ and Se+/se-) and 22.4% were non-secr…
