Bo'tous
this bioweapon was developed by the Yuuzahan Vong, and was based on the original coomb spore virus. The bo'tous was a tiny, beetlelike creature that was designed to be carried in a host for its gestation period, then expelled in several breaths. Nom Anor had planned to destroy the Jedi Knights by having the priestess Elan pose as a hostage so that she could gain audience with the Jedi. Elan allowed a colony of the spores to be implanted in her chest. When they reached maturing, she could expel them in four controlled breaths. The bo'tous was much more virulent than the coomb spore, killing both Yuuzhan Vong and humans in mere minutes. The bo'tous grew rapidly in the presence of oxygen. Also, as the spores consumed their victims, they produced offspring in the form of infected mites. These flying mites would then attempt to find a new host, thereby spreading the disease. Unfortunately, the mites only lived for a few seconds before expiring. In the end, Elan was unable to exhale her spores in the presence of the Jedi, and instead was killed herself when she inhaled it. Elan's familiar, Vergere, provided a form of antidote to the original coomb spore to Han Solo before she disappeared. The antidote helped Mara Jade Skywalker return to health.
