Chickens belong to animals, chordate phylum and chordate subphylum. They are avifauna, order Galliformes, pheasant family, Genus Gallus, and subspecies of domestic chicken. The chicken embryo is the main material of the measles vaccine, influenza vaccine and rabies vaccine. The virulence of some viruses can be weakened by chicken embryo passage, which is often used in the production and detection of virus vaccines and virological research. Marek's disease is a tumor disease caused by herpesvirus, which can be prevented by vaccines. It is the first tumor that can be prevented by vaccines. It also reveals that viruses can cause tumors in the body and can be prevented by vaccines. The knee joint and cross nerve reflex of 1-7 day old chicks can evaluate the efficacy of spinal cord sedatives. And 6~14 day old chicks can be used to evaluate the effect of drugs on blood vessel function. In vitro organs of chickens are also used for drug evaluation. The reproductive function of chicken declines with age and its egg-laying can be used as an objective index for aging research. The more common indicators of our Chicken ELISA kits are Chicken Endotoxin(EDT) ELISA kit; Chicken Insulin-like Growth Factor1(IGF1) ELISA kits; Chicken Interferonγ(IFNγ) ELISA kits etc.

What Are the Relevant Indicators of Infectious Diseases in Chickens?

Infectious Bursal Disease (IBD) in chickens is a highly contagious disease. The virus is transmitted through the environment, feed, etc. It can mix infection or secondary infect with Newcastle Disease, chronic respiratory disease, colibacillosis, and other diseases. The bursal disease infection can cause severe immunosuppression. Avian infectious rhinitis is caused by haemophilus parahaemophilus, which can delay the spawning period, mix infection in septicemia, lead to the induction of its activity and cause chronic respiratory diseases. Chicken Pullorum Disease is caused by salmonella, which is infected through the digestive tract, and this disease is limited to the reproductive system. Mild influenza in chickens is caused by the H9 virus with low pathogenicity. And the mortality rate and loss degree are related to the degree of secondary colibacillosis. Most of the above chicken diseases were diagnosed by serology.

Can Other Bird Samples Be Tested with Chicken Kits? Why? (Are there Any Homologies?)

No. In the classification of animals, birds belong to the animals about classes, and chickens belong to the animals about species, which are both warm-blooded and egg-laying, and both breathe with lungs. The main characteristics of birds are: streamlined bodies (spindle type), feathery body surfaces, and the forelimbs generally become wings (some species have wings degenerated), well-developed pectoral muscles, short rectum, large appetites, fast digestions (well-developed digestive systems), which helps to reduce weight and facilitate flight. Their hearts have two atria and two ventricles, and the heartbeats are fast. Body temperature is constant. In addition to the lungs, the respiratory organs also have airbags formed by protruding lung walls to help the lungs double breathe. Galliformes is located in a basic branch of the bird evolutionary tree, the classification system of DNA hybridization technology, and the 14-year classification system based on whole genome sequencing, which confirmed that they are closely related to Yaniformes. They also belong to the small classes of chicken and goose. Combining ND2, cyt b genes, and other nuclear genes, Galliformes can be divided into 7 families. Therefore, chickens and birds are not identical, and their samples are quite different.
