AVIAN LEUKOSIS Meaning and
Definition
-
Avian Leukosis is a contagious and neoplastic disease that affects birds, primarily poultry, caused by an oncogenic retrovirus known as Avian Leukosis Virus (ALV). This virus primarily targets the genetic material of the bird's white blood cells, resulting in abnormal cell division and the formation of tumors, particularly in the lymphoid tissues.
The disease can affect various avian species but is most commonly observed in chickens and turkeys, leading to considerable economic losses in the poultry industry due to decreased productivity and increased mortality rates. Avian Leukosis is transmitted horizontally through direct contact with infected birds or vertically through the egg, as the virus integrates into the host's germ cells.
Symptoms of Avian Leukosis can vary depending on the affected bird's age, immune response, and severity of infection. Common signs include progressive weight loss, decreased appetite, poor growth, pale comb, diarrhea, anemia, and frequent infections. In severe cases, affected birds may also exhibit increased mortality, tumors in various organs, and reproductive disorders.
Prevention and control measures for Avian Leukosis involve strict biosecurity protocols to prevent the introduction and spread of the virus in poultry farms. These include disinfection of facilities, isolation and quarantine of infected birds, depopulation of affected flocks, and vaccination programs. Genetic selection for resistance to the virus has also been implemented in certain chicken breeds to reduce the impact of the disease.
Overall, avian leukosis represents a significant health issue in poultry, requiring continuous monitoring and control efforts to minimize its impact on bird populations and the poultry industry as a whole.

Etymology of AVIAN LEUKOSIS
The word "avian" is derived from the Latin word "avis", meaning "bird". The term "leukosis" comes from the Greek word "leukos", meaning "white", and "osis", meaning "condition". "Leukosis" originally referred to a group of diseases characterized by an abnormal increase in white blood cells, but it is now specifically used to describe a type of cancer that affects birds. Therefore, "avian leukosis" refers to a condition of abnormal white blood cell proliferation specifically found in birds.
