Feline immunodeficiency virus (FIV) is a Lentivirus that affects cats worldwide, with 2.5% to 4.4% [1] [2] of felines being infected.. FIV was first isolated in 1986, by Niels C Pedersen and Janet K. Yamamoto at the UC Davis School of Veterinary Medicine in a colony of cats that had a high prevalence of opportunistic infections and degenerative conditions and was originally called Feline T ...
The virus is easily spread through direct contact between cats. The most common form of spreading is through saliva, as most multiple cat homes share food and water dishes. [11] Another major form of spreading is grooming or fighting. When an infected cat grooms a healthy cat, it leaves its contaminated saliva on the fur.
Feline diseases are often opportunistic and tend to be more serious in cats that already have concurrent sicknesses. Some of these can be treated and the animal can have a complete recovery. Others, like viral diseases, are more difficult to treat and cannot be treated with antibiotics, which are not effective against viruses.
Feline leukemia virus (FeLV) is a retrovirus that infects cats.FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. If not defeated by the animal's immune system, the virus weakens the cat's immune system, which can lead to diseases which can be lethal.
An important infectious skin disease of cats is ringworm, or dermatophytosis.Other cat skin infections include parasitic diseases like mange and lice infestations.. Other ectoparasites, including fleas and ticks, are not considered directly contagious but are acquired from an environment where other infested hosts have established the parasite's life cycle.

Lymphoma in young cats occurs most frequently following infection with feline leukemia virus (FeLV) or to a lesser degree feline immunodeficiency virus (FIV). These cats tend to have involvement of lymph nodes, spine, or mediastinum. Cats with FeLV are 62 times more likely to develop lymphoma, and cats with both FeLV and FIV are 77 times more ...
