Clinical diagnosis of schistosomiasis in Sudanese cattle.
This study was done in the White Nile Province to characterise the history and signs of naturally occurring Schistosoma bovis infection in cattle (Gorag). Necropsy and laboratory examinations were performed on 10 animals six to 30 months of age which were in poor condition. They were selected because of a history suggestive of schistosomiasis. All the animals showed some degree of S. bovis infection; eight had a moderate or heavy degree of infection. Also all had liver damage due to either past or active Fasciola gigantica infection. Although concurrent infection with these two trematodes is common an owner who diagnoses Gorag is most likely referring to the syndrome caused by S. bovis as being the major cause of the poor performance observed. Fasciolicide treatment may eliminate active fascioliasis as the principal damaging agent. Also differentiating signs of haemorrhagic diarrhoea, severely sunken eyed appearance and only moderate inappetence are common in animals with acute schistosomiasis.
