Parvoviruses are among the smallest viruses (hence the name, from Latin parvus meaning small) and are 18–28 nm in diameter. [16] Parvoviruses can cause disease in some animals, including starfish and humans. Because the viruses require actively dividing cells to replicate, the type of tissue infected varies with the age of the animal.
In hatcheries the diseases are often controlled by increasing the temperature to 15–18 °C. [20] Like all vertebrates, fish suffer from herpes viruses. These ancient viruses have co-evolved with their hosts and are highly species-specific. [21] In fish, they cause cancerous tumours and non-cancerous growths called hyperplasia. [22]
Rocky Mountain spotted fever* is a rickettsial disease that occurs in dogs and humans. It is caused by Rickettsia rickettsii and spread by ticks of the genus Dermacentor. Signs are similar to human disease, including anorexia, fever, and thrombocytopenia. [12] Clostridium species can cause diarrhea in dogs.

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.

The virus that causes AIDS, for example, crossed over from chimpanzees. And many experts believe the virus that caused the COVID-19 pandemic flowed from bats. But, as a new study shows, this ...
Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. [1] They are caused by infection with a variety of pathogens , including rickettsia and other types of bacteria , viruses , and protozoa . [ 2 ]
The number of viral spillover events of these four viruses from animals to humans increased by 5% annually from 1963 through 2019. ... The duo of viruses caused more than 90% of the 17,000-plus ...
