Malignant Melanoma in a Female Mallard Duck (Anas platyrhynchos)
Melanomas are malignant neoplasms originating from melanocytes. They reported in birds. In this case, macroscopic and microscopic (the histopathologic and IHC) findings supported a final diagnosis of cutaneous malignant melanoma in a mallard duck (Anas platyrhynchos). A female mallard duck (Anas platyrhynchos) was observed with a mass on the ventral portion of the neck. Th...
متن کاملCaecal Development in Kuttanad Duck (Anas Platyrhynchos Domesticus)
Caecum, the largest part of duck’s intestine has an important role in liquid absorption, cellulose digestion and defensive mechanism. Age related changes in the histomorphology of the caeca in Kuttanad ducks were studied in 72 birds from day-old to adult at fortnight intervals. After recording the biometry and gross features, the material was fixed in neutral buffered formalin and standard proc...
متن کاملDevelopmental ossification sequences of the appendicular and axial skeleton in Kuttanad duck embryos (Anas platyrhynchos domesticus)
The processes of ossification sequences are poorly investigated for birds in general, even for domestic and experimental species and when it comes to the waterfowl it is almost negligible. Such sequences constitute a rich source of data on character evolution, and may even provide phylogenetic information. A pre-hatch developmental study on ossification sequences of axial and appendicular skele...
متن کاملConditioning to magnetic direction in the Pekin duck (Anas platyrhynchos domestica).
The ability of ducks to derive magnetic direction information was tested in a conditioned procedure and the functional properties of the mechanism of magnetoreception investigated using common manipulations. Twelve ducks were trained to find a hidden imprinting stimulus behind one of three screens in a round arena. Once a criterion was reached, the directional choices of ducks were recorded in ...
متن کاملIdentification and Expression Analysis of the Interferon-Induced Protein with Tetratricopeptide Repeats 5 (IFIT5) Gene in Duck (Anas platyrhynchos domesticus)
The interferon-induced proteins with tetratricopeptide repeats (IFITs) protein family mediates antiviral effects by inhibiting translation initiation, cell proliferation, and migration in the interferon (IFN) dependent innate immune system. Several members of this family, including IFIT1, IFIT2, IFIT3 and IFIT5, have been heavily studied in mammals. Avian species contain only one family member,...
