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.
Causes include bacterial or viral infection, toxic insult, cancer, copper storage diseases, or it may be idiopathic. [182] Dental disease is very common. Calculus is the most obvious sign, but gingivitis progressing to periodontitis is what results in tooth loss. Treatment involves scaling and polishing of the teeth under general anesthesia and ...
The hepatitis C virus is the cause of hepatitis C and some cancers such as liver cancer (hepatocellular carcinoma, abbreviated HCC) and lymphomas in humans. [1] [2] [3] An oncovirus or oncogenic virus is a virus that can cause cancer. [4]
Bovine leukemia virus (BLV) is a retrovirus which causes enzootic bovine leukosis in cattle. It is closely related to the human T‑lymphotropic virus type 1 ( HTLV-I ). BLV may integrate into the genomic DNA of B‑lymphocytes as a DNA intermediate (the provirus ), or exist as unintegrated circular or linear forms. [ 2 ]
Cutaneous fibropapillomas caused by Deltapapillomavirus group have a nodular appearance. [7] Although unsightly, most skin warts rarely cause problems except in show animals. However, large warts may bleed, potentially leading to secondary infections, and florid warts of the teat can cause mastitis and interfere with suckling and milking. [3]
Herpesviruses also cause cancer in animals, especially leukemias and lymphomas. [13] Human T cell lymphotropic virus was the first human retrovirus discovered by Robert Gallo and colleagues at NIH. [20] The virus causes Adult T-cell leukemia, a disease first described by Takatsuki and colleagues in Japan [21] and other neurological diseases ...

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]
