Bacillus anthracis gamma phage lysis among soil bacteria: an update on test specificity.

ABSTRACT:

Background

Bacillus anthracis, which causes anthrax in humans and animals, is enzootic in parts of the U.S. state of Texas where cases are typically reported in animals annually. The gamma phage lysis assay is a common diagnostic method for identification of B. anthracis and is based on the bacterium's susceptibility to lysis. This test has been shown to be 97% specific for B. anthracis, as a small number of strains of other Bacillus spp. are known to be susceptible. In this study, we evaluated the performance of a combination of B. anthracis diagnostic assays on 700 aerobic, spore-forming isolates recovered from soil collected in Texas. These assays include phenotypic descriptions, gamma phage susceptibility, and real-time polymerase chain reaction specific for B. anthracis. Gamma
