Maasai peopleThe Maasai ('mɑːsaɪ,_mɑːˈsaɪ; Wamasai) are a Nilotic ethnic group inhabiting northern, central and southern Kenya and northern Tanzania. They are among the best-known local populations internationally due to their residence near the many game parks of the African Great Lakes and their distinctive customs and dress. The Maasai speak the Maa language (ɔl Maa), a member of the Nilotic language family that is related to the Dinka, Kalenjin and Nuer languages.
PolioPoliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.
CattleCattle (Bos taurus) are large, domesticated, bovid ungulates. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus Bos. Mature female cattle are referred to as cows and mature male cattle are referred to as bulls. Colloquially, young female cattle (heifers), young male cattle (bullocks), and castrated male cattle (steers) are also referred to as "cows". Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather.
Immunity (medical)In biology, immunity is the state of being insusceptible or resistant to a noxious agent or process, especially a pathogen or infectious disease. Immunity may occur naturally or be produced by prior exposure or immunization. The immune system has innate and adaptive components. Innate immunity is present in all metazoans, immune responses: inflammatory responses and phagocytosis. The adaptive component, on the other hand, involves more advanced lymphatic cells that can distinguish between specific "non-self" substances in the presence of "self".

Today, it is also found in Italy, the Balkans, Australia, North America, South America and some African countries. Two extant types of water buffalo are recognized, based on morphological and behavioural criteria: the river buffalo of the Indian subcontinent and further west to the Balkans, Egypt and Italy and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east.
