Site of initial chlamydia bearing creates large difference


“This investigate emphasizes a pre-exposure of chlamydia to a gastrointestinal (GI) tract as a vaccine,” pronounced Guangming Zhong, M.D., Ph.D., highbrow in a Joe R. Teresa Lozano Long School of Medicine during UT Health San Antonio.

The insurance is really strong and is opposite tissues, that is called transmucosal immunity. Protected sites embody a genital tract and a lungs, pronounced Dr. Zhong, whose expertise appointment is in a Department of Microbiology, Immunology Molecular Genetics.

The discovery, reported Nov. 13, 2017, in Infection and Immunity, indicates that exposing a tummy initial to chlamydia is a novel entrance to try in preventing a genital infection. However, when a genital tract is a site of initial chlamydia exposure, a opposite outcome might result. In this scenario, genital chlamydia spreads to a tummy and induces responses that foster serve illness in a genital tract. Dr. Zhong hypothesized this illness settlement in a examination essay published Dec. 27, 2017, in Trends in Microbiology.

Controlled transmission

Human bearing to chlamydia is unpredictable, maybe entrance by genital or non-genital passionate hit with an putrescent partner and maybe around hit with infested materials. The UT Health San Antonio scientists are utilizing a rodent indication that is a tranquil approach to investigate chlamydia transmission.

The group found that if a tummy is a initial site to be colonized by chlamydia bacteria, afterwards a mice are immunized opposite serve disease. The tummy infection is benign. But if a genital tract is a initial to be infected, a ensuing illness is harmful. This formula in a worse illness prognosis, including a probability of infertility since a illness is modernized before symptoms are evident.

“If we are unprotected to chlamydia in a GI tract first, it’s a vaccine, though if we are unprotected in a genital tract first, we might have extended disease,” Dr. Zhong said.

A probiotic for a gut

Dr. Zhong is exploring a probability that Chlamydia trachomatis, a micro-organism that causes chlamydia, could be delivered orally as a vaccine.

“We take probiotics for a GI health,” Dr. Zhong said. “In a future, we might supplement chlamydia as a probiotic for a gut. Once a germ are determined in a GI tract, they don’t spread.”

About 1.6 million cases of chlamydia were reported to a U.S. Centers for Disease Control and Prevention in 2016. Because many people have no symptoms and don’t get tested, a series of annual cases is estimated to be as high as 2.8 million.

Chlamydia is generally common among immature people, and a CDC estimates 1 in 20 intimately active immature women age 14-24 have a STD.
