What is NDV?
Newcastle disease virus (NDV) is a virus that is of interest because it replicates (makes copies of itself) more quickly in human cancer cells than in most normal human cells and because it can kill these host cells (see Question 1). NDV can be used to directly kill cancer cells, or it can be given as a cancer vaccine.
What does NDV stand for in medical terms?
Newcastle disease virus. A bird virus that is being studied in the treatment of cancer. It may be used to kill cancer cells directly, or it may be given as a cancer vaccine to stimulate the body’s immune system. NDV is a type of biological response modifier and vaccine therapy. Also called Newcastle disease virus.
Can Newcastle disease affect humans?
Humans aren’t normally affected, but people in direct contact with infected birds may develop a very short-term eye infection, which passes without treatment.
What is the treatment for Newcastle disease?
Since Newcastle disease is a viral infection, there is currently no treatment. Antibiotics are sometimes used to control secondary bacterial infections that result from the disease. A vaccine is available for birds and is routinely used in poultry flocks.

How is Newcastle disease prevented?
The disease can be prevented through vaccination and adaptation of strict bio-security and quarantine control measures. During the outbreak of disease proper disposal of dead birds and zoning of the area can help to control the disease in surrounding flocks.
How is Newcastle disease virus diagnosed?
The definitive diagnosis of ND is done through isolation and identification of the virus (Alexander, 1998). Tracheal and cloacal swabs are good sources of virus for isolation from living birds without having to kill them.
Are cormorants bad luck?
In northern Norway, cormorants are considered to be good luck when they gather in a village. Norwegian myth also states that people who die at sea can visit their former homes in the form of a cormorant. … In Ireland and some other places, seeing a cormorant perched atop a church steeple is a warning of bad luck to come.

How do you treat Newcastle disease in birds?
There is no specific treatment for Newcastle disease. Antibiotics can be given for three to five days to prevent secondary bacterial infections (antibiotics do not affect viruses). Increasing the brooding temperature for chicks by 5F may help reduce losses.

- Sneezing, gasping, nasal discharge, coughing;
- Greenish, watery diarrhea;

The I-2 Newcastle disease vaccine has been developed for local or regional production and use in controlling Newcastle disease in village chickens. Many Newcastle disease vaccines deteriorate after storage for one or two hours at room temperature.
What cells does Newcastle disease infect?
NDV selectively infects HeLa cells. A The presence of sialic acid was detected in HeLa and BHK cells by FACS analysis; unstained cells were used as a blank control. B Fluorescence microscopy images of NDV (GFP+) cells treated with different viral titers of NDV. Scale bars represent 50 m.
What is the best description of Newcastle disease?
Newcastle disease is an infection of domestic poultry and other bird species with virulent Newcastle disease virus (NDV). It is a worldwide problem that presents primarily as an acute respiratory disease, but depression, nervous manifestations, or diarrhea may be the predominant clinical form.

What causes Ranikhet disease?
It is caused by a virus in the family of paramyxoviruses. The disease appears in three forms: lentogenic or mild, mesogenic or moderate and velogenic or very virulent, also called exotic Newcastle disease. The lentogenic strains are very widespread, but cause few disease outbreaks.
Why is it called Newcastle?
The name Newcastle disease was given by Doyle as a temporary measure in order to avoid descriptive names that could confused with other diseases (Doyle, 1935). The pattern of outbreaks that are due to virulent NDV throughout the world suggest that several outbreaks have occurred in poultry since 1926.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
