Yersinia enterocolitica infection in patients with schistosomiasis

ABSTRACT

This study was carried out on 4 groups of subjects: group I included 54 bilharzial patients, group II 118 patients suffering from gastroenteritis, group III 62 pig's contacts, group IV 40 healthy individuals. The results of stool culture revealed only 3 positive cases among the diseased groups, contracts and healthy controls making an incidence of 1.7%. The IHA test showed a higher percentage of positivity [38.7%] in the group of pig's contact than the other groups, also the rate of positivity in bilharzial patients is higher than in patients of gastroenteritis [11.1% and 5.9% respectively]. ELISA showed the same sequence of positivity as IHA. The results of ELISA and IHA showed a fair agreement by Kappa measure, however, ELISA is more specific as out of 39 serum samples which gave positive IHA, 6 samples showed Brucella Abs and only 2 of them gave positive ELISA
