Wigglesworthia glossinidia was discovered by Sir Vincent Brian Wigglesworth, a British scientist who studied entomology (study of insects), in the gut of the tsetse fly. The gram-negative bacteria are classified in the Wigglesworthia genus for its discoverer, and glossinidia to indicate the bacteria’s origins. Which is to say, in the genus Glossina, which is placed in their own family Glossinidae (or the Tsetse fly). It has a symbiotic relationship with the fly, unable to survive outside its host it provides the fly with nutrients that can’t be acquired from the outside environment, without it the female fly cannot reproduce. More research is being done on the bacteria, as it’s coupled with the transmission of African trypanosomes, or sleeping sickness. Being able to extract Wigglesworthia from the gut of the fly may prove to prevent sleeping sickness, however research is slowed by the fact the bacterial cultivation in a laboratory setting has been so far unsuccessful.
