Backlit agar plate of viral simulant Escherichia
coli bacteriophage MS2 plaques
Staff Expertise
Technical staff members have significant field and laboratory
expertise with pathogenic and non-pathogenic Bacillus
species and their bacteriophages; BSL-2/3 design, operation,
procedures and training; and environmental surface testing for
detection of general enterics and Staphylococcus species. Other
laboratory evaluations include growth analysis (various media,
concentrations and environmental parameters) and biological dye
and enzyme utilization studies.
