leukosis

But the Eastern Europe states started to become leukosis free after the political changes at the end of the last century.

Only some animals later develop a B-cell leukemia called enzootic bovine leukosis.

The breed shows resistance to bovine leukosis.

Avian leukosis virus is an example of a virus that causes a disease by insertional mutagenesis.

More worrying is the rise of a related disease, Lymphoid leukosis, which is spread from infected females via hatching eggs.

Just before World War II, an infectious disease, leukosis, wiped out the flock of 2,000 leghorns.

Avian Sarcoma Leukosis Virus is characterized by a wide range of tumors, the most common of which are lymphomas.

She was later employed as an agent of the USDA to investigate the diseases of poultry and avian leukosis.

Species include the Rous sarcoma virus, avian leukosis virus, and avian myeloblastosis virus.

I'll have to brush up on pullorum, ornithosis, coccidosis, leukosis, perosis, and Ochsner knows how many other -osises and -itises.

Avian sarcoma leukosis virus (ASLV)

Newly hatched chicks infected with Avian leukosis virus will begin to form tumours begin to appear in their bursa of fabricus (like the human thymus).

Lymphoid Leukosis is a disease that affects chickens caused by the retrovirus Avian leukosis virus.

Avian Sarcoma and Leukosis Viruses (ASLV) have ten subgroups (A through J).

Avian sarcoma leukosis virus (ASLV) is an endogenous retrovirus that infects and can lead to cancer in chickens; experimentally it can infect other species of birds and mammals.

Direct interaction of diseases is in the case of genetic recombination among different pathogens, for instance between Avian sarcoma leukosis virus and Marek's disease virus (MDV) in domestic fowl.

In coinfected cells, the retroviral DNA of the avian leukosis virus can integrate into the MDV genome, producing altered biological properties compared to those of the parental MDV.

The direct repeat 1 (dr1) element is an RNA element commonly found in the 3' UTR of Avian sarcoma, Rous sarcoma and Avian leukosis viruses (Alpharetroviruses and Avian type C retroviruses).

Transgenic chickens developed by scientists at Michigan State University and the Federal Agriculture Department have been given genes that thwart viruses' ability to invade cells and are protected against avian leukosis virus, which causes an illness that is estimated to cost the poultry industry between $50 million and $100 million a year.
