| bites | Penetration of the skin (puncture or laceration) causing reactions that result from 1) mechanical injury; 2) injection of toxic material such as snake or scorpion venom; 3) injection of antigenic substance, especially by insect or arthropod bites, capable of inducing and eliciting allergic sensitization; 4) introduction of otherwise saprophytic flora such as Staphylococcus pyogenes in the instance of human bites; 5) invasion of the tissue as in myiasis; 6) transmission of disease such as typhus and rabies. Depending on the nature of the material propelled into the puncture of the skin and, in the case of antigenic material, on the previous exposure and immunity of the host, the local reaction will be immediate or delayed, accompanied by varying degrees of pain, itching and burning, and systemic manifestations specific for the offending agent.

| bithorax complex | <genetics, molecular biology> A group of homeotic mutations of Drosophila that map to the bithorax region on chromosome III. The mutations all cause the third thoracic segment to develop like the second thoracic segment to varying extents. The genes of the bithorax complex are thought to determine the differentiation of the posterior thoracic segments and the abdominal segments. (18 Nov 1997) |
