Galveston County Daily News (Internet / Print) 05/07/06 After an early morning run along the Seawall with two of his five dogs, Slobodan Paessler is ready for a day at the office. The cool breeze, the rhythmic sound of the ocean and the exercise provide an invigorating contrast to the claustrophobic scene that awaits him. As one of only a handful of research scientists in the country who work with samples of the deadly H5N1 avian flu virus, Paessler spends six or seven hours a day in a bulky biocontainment suit. Inside the windowless high-security biosafety level four laboratory on the University of Texas Medical Branch campus, Paessler is in the midst of a project testing the effects of anti-viral drugs on animals infected with the avian influenza A virus — known as H5N1, the highly publicized bug that can kill human beings.
