Department of Immunology and Molecular Microbiology
David C. Straus, PhD
David C. Straus is a Professor of Immunology and Molecular Microbiology at Texas Tech
University Health Sciences Center (TTUHSC) in Lubbock, Texas. Dr. Straus graduated
from Wright State University in Dayton, Ohio with a B.S. in Biology in 1970. He next
received a Ph.D. in Microbiology from Loyola University in Chicago, Illinois in 1974.
He next did Postdoctoral research in the Department of Microbiology at the University
of Cincinnati in Cincinnati, Ohio from 1974 to 1975 under Dr. Peter Bonventre. He
was then an Instructor of Microbiology at the University of Texas Health Sciences
Center in San Antonio (UTHSCSA) from 1975 to 1976. He then became an Assistant Professor
of Microbiology at the UTHSCSA from 1976 to 1981. He then moved to TTUHSC in 1981
where he became an Associate Professor of Microbiology where he received tenure in
1984. He was promoted to Full Professor of Microbiology and Immunology in 1995. Additional
positions he has held in his academic career include Instructor of Microbiology, Illinois
College of Podiatric Medicine, Chicago, Illinois, 1972 to 1973; Visiting Professor
of Microbiology, Department of Microbiology and Infectious Diseases, University of
Calgary, Calgary Canada, 1989-1990; and Visiting Professor, Trinity School of Medicine,
St. Vincents Island, 2011. He has won the three teaching awards at TTUHSC including
the President’s Excellence in Teaching award in 1996. He won the TTUHSC Dean’s Research
award in 2006. He is currently a member of Sigma X Research Society, the American
Society for Microbiology, and the American Academy of Microbiology. He has received
one patent for Pasteurella haemolytica vaccine inactivated by ultraviolet light, #6,303,130. His research has been funded
by NIH, the Cystic Fibrosis Foundation, The American Heart Association (Texas Affiliate),
the Canadian Cystic Fibrosis Foundation, the State of Texas Higher Education Coordinating
Board, QIC Systems, Millenium Technology Transfer, the Southwest Center for Occupational
and Environmental Health, Assured Indoor Air Quality, and Munter’s Inc. Indoor Air
Quality. He has published over 180 articles with 111 of those in peer-reviewed journals,
27 book chapters, and has edited one book on Sick Building Syndrome. He has reviewed
papers for numerous journals and is on the editorial board for the International Journal
of Microbiology, Toxins, and the Egyptian Journal of Microbiology. Finally, he is
a charter member of the TTUHSC Teaching Academy.
Dr. Straus has been involved in the research of pathogenic microorganisms for over
40 years. For the first 25 years he was involved in examinating the pathogenic mechanisms
involved in the disease processes caused by Streptococcus pyogenes, Corynebacterium diphtheriae, Pseudomonas aeruginosa, Viridans Streptococci, Klebsiella pneumoniae, Streptococcus agalactiae, Streptococcus zooepidemicus, Pseudomonas cepacia, Pasteurella haemolytica, and Pasteurella multocida. For the last 17 years, he has examined the Microbiology of the phenomenon known
as Sick Building Syndrome (SBS). His research in SBS has shown that certain fungi
are responsible for this phenomenon. These organisms include Penicillium chrysogenum and Stachybotrys chartarum which grow on cellulose containing building materials when buildings get wet. The
primary compounds these organisms produce in water damaged buildings (WDB) are spores
(aka conidia) and mycotoxins. His work has shown that the inhalation of high concentrations
of Penicillium chrysogenum spores cause allergic inflammation in an animal model (see figure) and that Stachybotrys chartarum when growing in WDB produces the potent trichothecine mycotoxins known as satratoxins,
which get into the air where they are inhaled by persons inside these buildings. This
is one possible explanation for the health complaints described by people in WDB where
these two organisms can be found. Dr. Straus is also examining the role of sulfur
oxidizing and reducing bacteria in Chinese drywall contamination.

- Fungal identifications.
- Detection of mycotoxins in the air.
