Biosensors and Bioassays for the Medical Detection of Bacillus Anthracis and Diagnosis of Anthrax.

Bacillus anthracis is a causative agent of the highly mortal disease anthrax. This zoonosis is present in nature, but it is also considered one of the most powerful biological warfare agents. A timely diagnosis is necessary for proper therapy and setting of epidemiological countermeasures. Current diagnostic methods should be used in specialized laboratories or medical facilities because there are only a limited number of methods suitable as hand-held assays or even point-of-care tests for detecting B. anthracis or anthrax diagnosis. The lateral flow tests are an exception in this regard, but these tests also have some limitations. Significant progress has been achieved in point-of-care tests for B. anthracis detection and anthrax diagnosis in various biosensors and bioassays. This review focuses on current hand-held and point-of-care tests that can easily prove anthrax or its causative agent outside the context of specialized facilities.
