[The absence of invasive amebiasis in male homosexual AIDS patients in Recife].

The purpose of this paper was to determine if among male homosexual AIDS [correction of SIDA] patients, the Entamoeba histolytica was able to product invasive illness. From the 77 investigated patients only one (1.3%) has cysts of E. histolytica in his stools. The electrophoresis of the only isolated strain has shown it was from zimodeme I, non pathogenic. The research of antiamebic antibodies was negative in the serum of the totality of patients. Those results showed that even in immunocompromised patients with AIDS [correction of SIDA], E. histolytica strain found in Recife was not able to produce disease. The utilization of metronidazol is not indicated in amoebic cysts carriers.
