Study confirms Caesarian best way to prevent herpes transmission at birth

For over 30 years, physicians have assumed that any expectant mother with genital herpes lesions at delivery must deliver her baby by Caesarian section to minimize chances of transmission of the disease to the infant, although there was no clinical or research information supporting that practice. A study by University of Washington physicians confirms that Caesarian section is indeed the way to go to prevent transmission of HSV (herpes simplex virus).

Scientists decipher tooth decay bug’s genome

Researchers in Oklahoma have deciphered the complete genome sequence of Streptococcus mutans, the main organism implicated in causing tooth decay. The work, supported by the National Institute of Dental and Craniofacial Research, has been made freely available online. Said one of the team members involved in the four-year effort: “Building on this basic research may one day lead us to new approaches for preventing and treating tooth decay.” Added another: “By targeting the adherence genes, for example, we might be able to develop a way of preventing S. mutans from sticking to teeth.”
