Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of non-human vertebrates. The disease is caused by trypanosomes of several species in the genus Trypanosoma such as T. brucei - which also infects humans to cause African Sleeping Sickness , and T. vivax which causes nagana in livestock mainly in ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in ...
Such issues may be associated with conditions like asthma, sleep apnea and cystic fibrosis. Chronic obstructive pulmonary disease (COPD) is another of the most common breathing conditions, but it ...
Social hierarchy, diet, brain size and body mass are contributing factors to how much sleep particular animals naturally need. Outside factors might even i Research Shows that Animals, too, Need a ...

Tuberculosis generally affects the lungs, but it can also affect other parts of the body. [1] Most infections show no symptoms, in which case it is known as latent tuberculosis . [ 1 ] Around 10% of latent infections progress to active disease that, if left untreated, kill about half of those affected. [ 1 ]
Trypanosoma of both the rhodesiense and gambiense types can affect other animals such as cattle and wild animals. [1] African trypanosomiasis has generally been considered an anthroponotic disease and thus its control program was mainly focused on stopping the transmission by treating human cases and eliminating the vector.
