Bacteria of several genera are able to form endospores when subjected to certain starvation conditions. The endospores are dormant forms that are structurally and biochemically different from the corresponding growing or vegetative cells. These bacterial endospores resist antibiotics, desciccation, and ordinary boiling than the vegetative cells. The detection of bacterial endospores can be important for a wide variety of purposes. In the sanitation and hygiene fields, detection of bacterial spores can be critical to monitor indoor environments, water quality and food quality. Similarly, in the public health perspective detection of bacterial spores is very important in ensuring regulation of safer transfusion and other therapeutic products, administered either orally or intravenously. Monitoring of bacterial spores is gaining importance even in other areas such as agriculture wherein soil or plant samples are periodically monitored for bacterial spores to ensure high levels of the bacterial population/toxin to be effective against insect pests. More recently, with the possibility of bacterial spores being used as bio-threat agents there has been an augmented effort in developing much more sensitive, specific and rapid detection systems for bacterial spores. The review discusses about current methods of bacterial spore detection and the challenges involved read more ...
