(Oct. 13) -- Another porn actor in California's lucrative adult film industry has tested positive for the AIDS virus, leading two companies to halt production.

The positive HIV test was confirmed to the Los Angles Times by the Adult Industry Medical Healthcare Foundation, a clinic in Sherman Oaks that serves the porn industry. Jennifer Miller, a counselor at the clinic, would not disclose the person's gender or employers.

"We are quarantining and testing all exposed partners to the individual," Miller told the Times.

Two of the industry's largest companies, Vivid Entertainment and Wicked Pictures, suspended filming on Tuesday as a precaution, the Times said.

"We will wait for all of the facts to emerge before we resume production," Vivid co-founder Steven Hirsch told the paper.

The test renewed calls for condoms to be mandatory for porn performers.

"How many more people have to be infected with HIV before Los Angeles County steps in to do its job and protect performers' and the public's health?" Michael Weinstein, president of AIDS Healthcare Foundation, told the paper.

A woman tested positive for the virus last year, and an HIV outbreak that affected several actors stopped production at some studios in 2004
