Study on molecular epidemiology of rotaviruses among newborns and infants of ethnic minorities

is paper reports that the HRV detection results from different ethnic minorities in In-ner Mongolia,China,146 meconium and 1 16 acute diarrhea samples were cullected from hos-Ditalized newborns and infants during winter diarrhea period in 1 993 and were examined byPAGE and McAb VP_6 ELISA.The results showed that different ethnic minority areas hadthe same predominant electropherotype,but different subtypes.HRV detected in newbornmeconium had clear genotypes of HRV group A and all belong to subgroup Ⅱ(long electro-pherotype).High HRV positive rate was found in certain area,but there was no correlationsbetween either ethnic races or geographical locations.According to epidemic investigation,lo-cal environmental hygiene level was the main infection factor of the disease.This conclusionwas further confirmed by McAb VP6 ELISA.
