PCR-Based Detection of Bacillus anthracis in Formalin-Fixed Tissue from a Patient Receiving Ciprofloxacin

摘要

We demonstrate that Bacillus anthracis may be detected from a formalin-fixed, paraffin-embedded biopsy specimen, even after the patient has received antibiotic treatment. Although traditional PCR methods may not be sufficiently sensitive for anthrax detection in such patients, cycle numbers can be increased or PCR can be repeated by using an aliquot from a previous PCR as the template.
