Etiología de la uretritis masculina. Estudio en 100 pacientes

Abstract

We studied 100 patients with symtoms of urethritis in order to determine the frequency of infection with Neisseria gonorrhoeae and Chlamydia trachomatis. Diagnosis were made by culture in Thayer Martin medium and McCov célls and by antigen detection using an ELISÁ test. A Gram-stained smear of the urethral exudate was also performed in order to detect the number of polymorphonuclear leukocytes (PMN) and the presence of intracellular Granegative diplococci. N. gonorrhoeae was isolated in 13 patients, in al1 of whom the number of PMNs was > 5 x mf and in 12 Gram negative diplococci could be detected. C. trachomatis infection was diagnosed in 27 patients: in 11 both techniques were positive; in 15 only ELISA was positive and 1 by culture only. The cellular reaction was variable. One patient was infected with both microoganisms. Our results indicate the relevance of C. trachomatis as the agent of nongonococcal urethritis in men and the importance of its laboratory diagnosis.
