Staphylococcus saprophyticus
QuestionChoice
This man is presenting with symptoms of a urinary tract infection. Schistosoma haematobium is a trematode worm found in contaminated water in tropical and subtropical areas which causes schistosomiasis. It gains access to the host through the skin, matures in the liver and lays eggs which can travel to and penetrate the bladder. This can cause bladder calcification in addition to other complications. It is treated with praziquantel.
