For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.

It is motile at temperatures of 22–29°C (72–84°F), but becomes nonmotile at normal human body temperature. [ 1 ] [ 2 ] Y. enterocolitica infection causes the disease yersiniosis , which is an animal-borne disease occurring in humans, as well as in a wide array of animals such as cattle, deer, pigs, and birds.
An interesting feature peculiar to some of the Yersinia bacteria is the ability to not only survive, but also to actively proliferate at temperatures as low as 1–4 °C (e.g., on cut salads and other food products in a refrigerator). [4]
Mammals can get parasites from contaminated food or water, bug bites, sexual contact, [7] or contact with animals. Some ways in which people may acquire parasitic infections are walking barefoot , inadequate disposal of feces , lack of hygiene , close contact with someone carrying specific parasites, and eating undercooked foods, unwashed ...
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
Pinworm infection (threadworm infection in the UK), also known as enterobiasis, is a human parasitic disease caused by the pinworm, Enterobius vermicularis. [3] The most common symptom is pruritus ani , or itching in the anal area. [ 1 ]
Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
