Campolina emphasized structure idealized for stereotyped, smooth and even paced gait. The newer examples of this breed display refinement in the torso, the nasal bones and around the mouth. These morphological changes confer increased degrees of freedom in joint movement and by extension, increased versatility generally in range and types of motion. The Campolina is used for pleasure and trail riding including dressage, and also driving. The Campolina breed is a young breed relative to other established horse lines (Akhal Teke, Arabian, Lippizan) and breed standards are still evolving. Current trends have suggested a move away from the square mouth and
Animal trypanosomiasis some breeds of cattle, notably the N'Dama – a West African "Bos taurus" breed. This contrasts with the susceptibility shown by East African "Bos indicus" cattle such as the zebu. Most trypanosomes develop in tsetse flies (Glossina spp.), in its biological vector, about one to a few weeks. When an infected tsetse fly bites an animal, the parasites are transmitted through its saliva. It can also be spread by fomites such as surgical instruments, needles, syringes. The most important vectors are thought to be horseflies (Tabanidae) and stable flies (Stomoxys spp.). The immune response of animals could be unable to
