Could a dimetrodon spit poison

Dimetrodon belongs to a group of reptiles that later evolved into mammals. Some of these reptiles were said to be poisonous. However, no suggestions have been made about dimetrodon being able to "spit" poison like a sppiting cobra. It´s likely it didn´t inject poison because otherwise scientist would have found hollow fangs like in the case of venomous snakes. It´s quite possible that dimetrodon´s mouth was full of deadly bacteria, like in the case of komodo dragons and crocodiles, which would be just as deadly.
