Abstract
This study was done in the White Nile Province to characterise the history and signs of naturally occurringSchistosoma 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 ofS. bovis infection; eight had a moderate or heavy degree of infection. Also all had liver damage due to either past or activeFasciola gigantica infection. Although concurrent infection with these two trematodes is common an owner who diagnoses Gorag is most likely referring to the syndrome caused byS. 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 inappetance are common in animals with acute schistosomiasis. Cette étude a été menée dans la province du Nil blanc pour définir l'histoire et les symptômes de l'infestation naturelle àSchistosoma bovis chez les bovins (Gorag). Des autopsies et des examens de laboratoire ont été effectués sur 10 animaux agés de 6 à 30 mois qui étaient en mauvaise condition physique, choisis en raison d'observations suggérant la Schistosomose. Tous les animaux présentaient un certain degré d'infestation àS. bovis. 8 d'entre eux avaient une infestation modérée ou forte. Tous présentaient aussi des lésions du foie dues à une infestation passée ou active àFasciola gigantica. Quoique l'infestation simultanée par ces deux parasites soit commune, un éleveur qui diagnostique le Gorag fera le plus souvent référence au syndrome causé parS. bovis comme étant la cause principale des mauvais résultats zootechniques observés. Un traitement contre les Fascioles peut éliminer la fasciolose comme principal agent nocif. De plus, des signes particuliers tels que diarrhée hémorragique, les yeux creux et seulement une inappétance modéré sont communs chez les animaux atteints de schistosomose aigue. El estudio tuvo lugar en la Provincia del Nilo Blanco, para caracterizar la historia y síntomas clínicos naturales de la infección porSchistosoma bovis (Gorag). Se realizaron necropsias en 10 animales que estaban en malas condiciones físicas, y en edades comprendidas entre 6 y 30 meses. Estos se seleccionaron mediante exámenes clínicos que sugirieron la infección. Todos los animales estudiados tenían algun grado de esquistosomiasis; ocho de ellos tenían una infección moderada o grave. También se encontró daño hepático en el total examinado, debido a infecciones pasadas o activas deFasciola gigantica. Aunque la infección con estos dos tremátodos es comun en la zona, los dueños de animales que diagnostican Gorag están de acuerdo en que elS. bovis constituye el mayor problema de la provincia. Los tratamientos periódicos con drogas especificas contra fascioliasis podrían eliminar la enfermedad activa. Otros síntomas de esquistosomiasis que sirven para diferenciarla de fascioliasis, son la diarrea hemorragica, ojos hundidos e inapetencia moderada.Keywords
