在男性生殖器感染病中急性附睾炎的发病率是比较高的,但因不易从病灶中检出病原体,故难以确定引起发炎的病原菌。以前曾被指出,这与泌尿系统感染有关。虽然有报告说,从急性附睾炎患者尿中所分离出的细菌是以大肠杆菌为主的革兰氏阴性杆菌为多,但其检出率也并不高,约半数以上引起发炎的病原菌不明. In male genital infection, the incidence of acute epididymitis is relatively high, but it is difficult to identify the pathogen causing inflammation since it is not easy to detect the pathogen from the lesion. It has previously been pointed out that this is related to urinary tract infections. Although there are reports of bacteria isolated from the urine of patients with acute epididymitis Escherichia coli-based Gram-negative bacteria are more, but the detection rate is not high, about more than half of the pathogenic bacteria causing inflammation unknown .
