- W2019975798 abstract "A single antigen indirect immunofluorescence test was used to screen for chlamydial antibody among Malaysian infants, children, sexually active adults and prostitutes. Of 794 serum samples tested, 361 (45.5%) were positive. Seropositivity increased with age and sexual activity and ranged from 10 to 16% among children under 10 years old to 94.4% among prostitutes. Pregnant women and female adolescents showed a higher antibody prevalence than nonpregnant and older women. Six (13%) infants under 6 months of age were positive for chlamydial IgM.794 sera from urban Malaysians (Kuala Lumpur and Petaling Jaya) were screened for Chlamydia with an indirect immunofluorescence kit (Chlamydia-Spot IF Kit, BioMerieux, France) between August 1988-July 1989. 86% of the donors were Chinese: 251 asymptomatic males and 234 females; 101 women attending prenatal clinics; 46 infants under 6 months; 97 female and 11 male prostitutes; and 54 men attending a clinic for sexually transmitted diseases (STDs). Sera were tested at a single dilution: 1/16 for men, 1/64 for women and neonates, and 1/8 for chlamydial IgM testing and infants. The overall seropositivity rates were 43.3 for m en, 24.8% for women, 34.7% for pregnant women, 94.4% for prostitutes, and 72.2% for men with STDs. Positive titers increased from 16.2 to 72.2% with age in men. They were highest in women aged 11-20, 25.6% and 50, 66.7%. 13% of the infants were positive for IgM anti-chlamydial antibodies, possibly suggestive of intrauterine infection, and 39% were positive for IgG, porbably from placentral transfer." @default.
