Capillaria philippinensis - a human intestinal nematode newly introduced to Upper Egypt

A twenty nine year old house wife from EI-Welydia region, who never left As siut, presented with chronic watery offensive diarrhoea, severe abdominal c ramping colicky pain, repeated vomiting and rapid loss of weight within six months. Ultrasonography revealed mild ascites and a small stone in the nec k of the gall bladder. Eggs of Capillaria philippinensis were for the first time recovered from Upper Egypt by direct smears. Unfertilized eggs were r ecognized for the first time and were found to differ morphologically from fertilized eggs. Trials to infect laboratory rats through swallowing of emb ryonated eggs proved unsuccessful.
