Title: Characterization of Egyptian isolates of Trichomonas vaginalis: I. Serotyping. Author: Azab ME, Salem SA, Abd el Ghaffar FM, el Sherif EA, Habib KS, Habib FS. Journal: J Egypt Soc Parasitol; 1992 Dec; 22(3):775-82. PubMed ID: 1431296. Abstract: Antitrichomonal hyperimmune sera against T. vaginalis stocks isolated from Egyptian female patients were employed for serological differentiation of somatic and soluble antigens in the Ouchterlony gel double immunodiffusion technique. It was concluded that soluble trichomonal antigens present in association with living flagellates are stock--specific reacting with some, but not all the antitrichomonal hyperimmune sera, while those present in association with dead parasites are common antigens reacting with all the sera. Three stocks, E1, E2 and E3 could be differentiated into two strains using their stock--specific antigens. The somatic antigens of six trichomonal stocks reacted with all the hyperimmune sera denoting common antigenic make up.[Abstract] [Full Text] [Related] [New Search]
