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.
An accident in a laboratory at the Lanzhou Veterinary Research Institute caused 65 workers to become infected with brucellosis. [73] More than 10,000 residents of Lanzhou were infected by November 2020. [74] The outbreak was reportedly caused by incompletely sterilized waste gas from a nearby biopharmaceutical factory.
Contagious equine metritis - Caused by Taylorella equigenitalis. Foal septicemia - Caused by various gram negative bacteria. Glässer’s disease - Disease in pigs caused by Haemophilus parasuis. AKA Porcine polyserositis, Infectious polyarthritis. Histophilosis - Disease in cattle caused by Histophilus somni (formerly Haemophilus somnus). AKA ...
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.

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]
Ncp viruses can induce persistent infection in cells and have an intact NS2/3 protein. In cp viruses the NS2/3 protein is either cleaved to NS2 and NS3 or there is a duplication of viral RNA containing an additional NS3 region. [15] The majority of BVDV infections in the field are caused by the ncp biotype. [1]
Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal.
