Disclosed are methods, probes, and nucleic acid sequences for the systematic identification of sporulation genes in spore forming bacteria. A probe comprises a nucleic acid sequence able to form a detectable hybrid with highly conserved regions of the spoOA gene of certain spore forming bacteria Bacillus and Clostridium bacteria species, said nucleic acid sequence being unable to form a detectable hybrid with genetic material of non-spore forming bacteria. Amplification of a portion of the spoOA gene from the cellular DNA of a spore forming bacteia by a polymerase chain reaction using such probe primer or , nucleic acid sequence as one member of a primer set results in the generation …

Why it's free to use
- Filed May 15, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 15, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
