Ethnicity - an arbitrary classification of the social group a person belongs to, and either identifies with or is identified with by others, as a result of a complex of cultural, biological, geographical and other factors such as linguistic, dietary and religion traditions; ancestry, background, allegiance, or association; and physical characteristics traditionally associated with race.

According to the study, a protein identified as EtpA and secreted by various strains of ETEC interacts with the intestinal epithelial cells of blood group A individuals causing severe diarrhoea.

James Fleckenstein, professor of medicine and molecular microbiology at the Washington University School of Medicine and an author of the study, says the work focused on the binding of the EtpA protein of the specific H10407 strain of ETEC on blood group A using a group of healthy volunteers in the US.

He explained that the study though was based on earlier work of investigators at the International Centre for Diarrhoeal Disease Research in Dhaka, Bangladesh, who had previously shown that children naturally exposed to ETEC are more likely to get sick if they are blood group A.

We are not suggesting that we should be blood typing all individuals with diarrhoea, but individuals with blood group A appear to be at highest risk for severe infection and stand to benefit the most in terms of preventing the most severe form of illness, Fleckenstein tells.
