A NOTE ON THE OCCURRENCE OF A COLEOPTEROUS LARVA IN THE 

 URINARY TRACT OF MAN IN THE ANGLO-EGYPTIAN SUDAN.

Government Entomologist, Anglo-Egyptian Sudan, Khartoum. 



The larva figured in the accompanying illustration was obtained from the urinary 

 tract of a native of Mongalla Province, Anglo-Egyptian Sudan. A careful search 

 through the literature at our disposal has failed to reveal any reference to a similar 

 case of parasitism of a Coleopterous larva in the urinary tract. 



The history of the case was as follows : — ■ 



The patient, for some time, had suffered from debility, difficult and painful 

 micturition and haematuria. He was examined at Yei Hospital by Captain Simson, 



R.A.M.C, who formed the opinion that the patient was suffering either from a stone 

 in the bladder or urinary bilharziosis. A sound was passed but no stone was detected 

 in either the patient's urethra or bladder. Microscopical examination of the urine, 

 however, showed that the ova of Schistosomum haematobium were present. He was 

 kept under observation in hospital, but the symptoms, instead of abating, became 

 worse, the patient complaining of severe strangury, apparently due to some 

 obstruction in the genito-urinary tract. His urethra was then douched out with 

 a weak solution of potassium permanganate and, after considerable straining, 

 numerous Coleopterous larvae were ejected from the urethral meatus. The next 

 day another urethral douch was administered with similar results. This was followed 

 by total relief of the symptoms, and the patient left hospital apparently cured.
