Washington — For the second time this year, the federal government has failed to stop a man infected with a dangerous strain of tuberculosis from traveling in and out of the United States. U.S. officials last spring were unable to catch a Mexican man infected with the disease because the doctor treating the man did not know his real name, according to a government official who was briefed on the incident but requested anonymity because the official was not authorized to discuss it publicly.

AUSTIN – Federal authorities are investigating two cases from last year in which Texas A&M researchers were infected with biological weapons agents – including the university's failure to report the exposures when they happened.

New documents obtained by The Sunshine Project, an Austin-based bioweapons watchdog group, show three researchers tested positive for exposure to the weapons agent Q fever in April 2006, two months after another researcher fell ill following contact with the agent Brucella.
