Rare chlamydia strain 'infecting gay men'

A particularly bad strain of chlamydia not usually seen in the US appears to be slowly spreading among gay and bisexual men, and the infection may increase their chances of getting or spreading the AIDS virus.

Called LGV chlamydia, the sexually transmitted disease has caused a worrisome outbreak in Europe, where some countries have confirmed dozens of cases. Diagnoses confirmed by US health officials are still low, just 27 since they warned a year ago that the strain was headed here.
