Friendly bacteria in humans may protect against HIV

Scientists have identified good bacteria already living in some humans that target and trap HIV and may protect against infection. They report their findings today at the 2005 American Society for Microbiology Beneficial Microbes Conference.

"I believe every life form has its natural enemy, and HIV should not be the exception," says Dr. Lin Tao, Associate Professor of the Department of Oral Biology, College of Dentistry, University of Illinois at Chicago. "If we can find its natural enemy, we can control the spread of HIV naturally and cost-effectively, just as we use cats to control mice."

The bacteria are strains of lactobacillus, commonly found colonizing the oral and vaginal cavities of humans. They do not cause disease. They target HIV because the virus is coated with the sugar mannose, which they use as a food source.

"Different bacteria have different sugar preferences," says Tao. "To block HIV, however, we needed to find bacteria that prefer the unusual sugar mannose and thus can capture it."

To identify bacteria that target mannose, Tao and his colleagues isolated oral and vaginal lactobacilli from healthy humans and tested the ability of different strains to bind to baker's yeast, another microorganism coated with mannose-rich sugars. They found a small group of lactobacilli that bound to mannose and further testing against HIV revealed two strains that specifically trapped the virus and blocked infection.

Due to high rates of mutation, repeated attempts at developing a vaccine to protect against HIV have failed. Inoculating the major mucosal surfaces where HIV transmission occurs with the HIV-capturing lactobacilli may provide a safe and cost-efficient method for preventing the spread of HIV, says Tao.

"This method can protect infants against HIV in breast milk and women against HIV upon sexual contact unobtrusively and inconspicuously via fermented foods or feminine products," says Tao. "If the method can be
