Culling

The process of removing, and usually killing, animals from a group based on specific criteria such as infection or contamination.

Pullorum Typhoid (PT)

Fowl typhoid and pullorum disease are caused by two very closely related organisms of Salmonella enterica. Pullorum disease is usually symptomatic only in young birds. The mortality rate varies, but it can be as high as 100%. Fowl typhoid resembles pullorum disease in young birds, but it is also a serious concern in growing and adult poultry.

Signs of PT include:
White diarrhea
Pasted vent
Huddle together
Lameness
Difficulty breathing

Quarantine

An imposed time period of isolation usually to prevent the spread of a disease.

Incineration

Complete combustion of organic compounds. This is a biologically safe method but may be slow and expensive. There may be concerns about air pollution.

Rendering

High temperatures and pressure break down animal remains. This requires transportation off site but recycles carcasses into reusable protein feed.

Compost

Decomposition of organic waste by microorganisms.

Mycoplasma gallisepticum

Mycoplasma gallisepticum is a bacteria that causes respiratory disease in chickens, turkeys, and other game birds flocks. It is spread through contact with contaminated equipment and surfaces or exposure to infected birds.

Signs of Mycoplasma include:
Watery eyes and nostrils
Swelling around the eyes
Coughing and sneezing
Inactivity

Polymerase Chain Reaction (PCR)

A technique for rapidly synthesizing large quantities of a given DNA segment.

Virus

A virus is a very small entity that consist essentially of a core of RNA or DNA surrounded by a protein coat that replicates, or copies itself, inside living cells

Vaccination

The introduction of a weakened or killed microbe into the body in order to stimulate the immune system to produce antibodies against that microbe, thereby preventing disease upon next exposure.
