Isäntäeläin, or the host animal in translation, refers to an organism that harbors or maintains a harmful organism or a free-living pathogen. The isäntäeläin itself is not necessarily harmed, but it provides a suitable environment for the parasite to grow and multiply.

The symbiotic relationship between the isäntäeläin and the parasite is known as commensalism. This type of symbiosis helps the parasite to survive and propagate, and it can also benefit the isäntäeläin by providing immune responses or protection against other predators.

Examples of isäntäeläin include humans who are infected by tapeworms, such as Taenia saginata or Diphyllobothrium latum. In these cases, the parasite develops in the human's intestines, where it feeds on nutrients and multiplies, causing various symptoms such as malabsorption and weight loss.

Other examples of isäntäeläin include mammals that host tickborne diseases, such as the mouse that maintains the tick that carries the disease-causing bacteria Rickettsia akari. In this case, the mouse is not typically harmed by the tick, but the tick benefits from the mouse's body heat, humidity, and oxygen levels.

Understanding the isäntäeläin is important for developing control measures for the spread of diseases and parasites. For example, targeting the host animal for intervention and treatment can be effective in reducing the spread of the parasite. This knowledge is useful for veterinarians, medical professionals, and researchers studying diseases and parasites.
