==Hosts==
'''Intermediate hosts''': Blackflies.
'''Definitive hosts''': Cattle
==Identification==
''O. gutturosa'' are thin, white worms. The females are capable of growing up to 60cm in length. The males are considerably smaller at around 4cm in length.
==Life Cycle==
Microfilariae are found on the surface of the host. Blackflies feed and ingest the microfilariae. These develop and mature into L3 larvae. The blackflies then feed on another host, which becomes infected.
