Parasitic diseases in poultry
A parasite is an organism that lives in or on another organism (referred to as the host) and gains an advantage at the expense of that organism. The two types of internal parasites that affect poultry are worms and protozoa. Usually, low levels of infestation do not cause a problem and can be left untreated. Clinical signs of a parasite infestation include unthriftiness, poor growth and feed conversion, decreased egg production, and, in severe cases, death. Also, parasites can make a flock more susceptible to diseases or worsen a current disease condition. External parasites can also cause problems for small flock poultry producers and occasionally for large flock producers. These unwanted visitors can be brought into the poultry house by wild birds or new birds being added to the flock. All new birds should be checked for parasites before they are mixed with the original flock.
Each year, U.S. poultry producers raise about 7 billion broilers. They use a combination of antibiotics and vaccines to protect these birds from infectious diseases. Antibiotics are critical to ongoing efforts to fight off diseases and infections; they have been able to kill or stop growth of many different kinds of protozoa and parasites as well as bacteria.

Wide use of a mushroom extract to protect poultry against a major parasitic disease is now closer, thanks to an Agricultural Research Service scientist and her South Korean colleagues.
The researchers -- led by immunologist Hyun Lillehoj at the ARS Animal Parasitic Diseases Laboratory in Beltsville, Md. -- developed a technique for controlling coccidiosis, which costs the world's poultry industry billions of dollars in losses annually.
The new method is the subject of a patent...

An Agricultural Research Service immunologist has pioneered a novel technology that will help develop nonchemical methods to control diseases that affect poultry. ARS is the U.S. Department of Agriculture's (USDA) chief scientific research agency.
Whether baked, broiled or barbecued, poultry is an important source of dietary protein. But its production has become increasingly threatened by a disease called coccidiosis, which costs the U.S. poultry industry about $700 million annually....

assalam o alaikum all my friends on this forum. I want to ask one thing more that most often the birds do light yellow droppings and sometimes dark brown droppings in poultry farms but there is not any kind of mortality there. If we say poultry farms to get the birds droppings tested in laboratory,he often hesitates and says that there is no mortality then why should I go for diagnosis? I want to ask that if i should treat for enteritis or coccidiosis if birds do light yellow or dark brown...
