Turkeys: Large woodland game BIRDS in the subfamily Meleagridinae, family Phasianidae, order GALLIFORMES. Formerly they were considered a distinct family, Melegrididae.TurkeyPoultry Diseases: Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.Ovomucin: A heterogeneous mixture of glycoproteins responsible for the gel structure of egg white. It has trypsin-inhibiting activity.Chickens: Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.Black Sea: An inland sea between Europe and Asia. It is connected with the Aegean Sea by the Bosporus, the Sea of Marmara, and the Dardanelles.Air Sacs: Thin-walled sacs or spaces which function as a part of the respiratory system in birds, fishes, insects, and mammals.Pneumovirus: A genus of the family PARAMYXOVIRIDAE (subfamily PNEUMOVIRINAE) where the human and bovine virions have neither hemagglutinin nor neuraminidase activity. RESPIRATORY SYNCYTIAL VIRUS, HUMAN is the type species.Avastrovirus: A genus of ASTROVIRIDAE infecting avian species and often involving extra-intestinal manifestations. The type species is Turkey astrovirus.Bird Diseases: Diseases of birds not considered poultry, therefore usually found in zoos, parks, and the wild. The concept is differentiated from POULTRY DISEASES which is for birds raised as a source of meat or eggs for human consumption, and usually found in barnyards, hatcheries, etc.Bordetella avium: A species of BORDETELLA isolated from the respiratory tracts of TURKEYS and other BIRDS. It causes a highly contagious bordetellosis.Herpesvirus 1, Meleagrid: A species in the genus MAREK'S DISEASE-LIKE VIRUSES, in the family HERPESVIRIDAE, infecting turkeys.Herpesvirus 2, Gallid: The type species of the genus MARDIVIRUS in the family HERPESVIRIDAE. It is the etiologic agent of MAREK DISEASE, infecting domestic fowl and wild birds.Herpesviridae: A family of enveloped, linear, double-stranded DNA viruses infecting a wide variety of animals. Subfamilies, based on biological characteristics, include: ALPHAHERPESVIRINAE; BETAHERPESVIRINAE; and GAMMAHERPESVIRINAE.Poultry: Domesticated birds raised for food. It typically includes CHICKENS; TURKEYS, DUCKS; GEESE; and others.Pneumovirinae: A subfamily of PARAMYXOVIRIDAE containing two genera: PNEUMOVIRUS; and METAPNEUMOVIRUS.Zeolites: Zeolites. A group of crystalline, hydrated alkali-aluminum silicates. They occur naturally in sedimentary and volcanic rocks, altered basalts, ores, and clay deposits. Some 40 known zeolite minerals and a great number of synthetic zeolites are available commercially. (From Merck Index, 11th ed)
