A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often (though not always) without causing disease for the reservoir itself. By some definitions a reservoir may also be an environment external to an organism, such as a volume of contaminated air or water. [1] [2]
The black rat is a reservoir host for bubonic plague. The rat fleas that infest the rats are vectors for the disease. In biology and medicine, a host is a larger organism that harbours a smaller organism; [1] whether a parasitic, a mutualistic, or a commensalist guest . The guest is typically provided with nourishment and shelter.
The bumblebee is a potential reservoir for several pollinator parasites. Commercially bred bumblebees used to pollinate greenhouses can be reservoirs for several pollinator parasites including the protozoans Crithidia bombi, and Apicystis bombi, [10] the microsporidians Nosema bombi and Nosema ceranae, [10] [11] plus viruses such as Deformed wing virus and the tracheal mites Locustacarus ...
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

These three areas can have very different abiotic conditions and, hence, host species that are specifically adapted to live there. [1] Two important subclasses of lakes are ponds, which typically are small lakes that intergrade with wetlands, and water reservoirs. Over long periods of time, lakes, or bays within them, may gradually become ...
In parasitology and epidemiology, a host switch (or host shift) is an evolutionary change of the host specificity of a parasite or pathogen. For example, the human immunodeficiency virus used to infect and circulate in non-human primates in West-central Africa, but switched to humans in the early 20th century.
Humans are the main reservoir hosts of L. tropica. [9] Rock hyraxes (Procavia capensis) [9] are a possible reservoir in Israel. [10] Natural infection by L. tropica has also been demonstrated in domestic dogs, [10] red foxes, golden jackals, gundis, and other species of wild rodents. [3] The main sandfly [10] vector for L. tropica is ...
Salmonella species lead predominantly host-associated lifestyles, but the bacteria were found to be able to persist in a bathroom setting for weeks following contamination, and are frequently isolated from water sources, which act as bacterial reservoirs and may help to facilitate transmission between hosts.
