Preparation of Guinea Fowl Blood Grouping Reagent by Turkey Normal Sera

First complete genome sequence of European turkey coronavirus suggests complex recombination history related with US turkey and guinea fowl coronaviruses.

A full-length genome sequence of 27,739  nt was determined for the only known European turkey coronavirus (TCoV) isolate. In general, the order, number and size of ORFs were consistent with other gammacoronaviruses. Three points of recombination were predicted, one towards the end of 1a, a second in 1b just upstream of S and a third in 3b. Phylogenetic analysis of the four regions defined by th...

Methods for Cryopreservation of Guinea Fowl Sperm

Conservation of indigenous poultry species is an important part of the new Hungarian agricultural strategy. Semen cryopreservation is the most practical method for the long term storage of poultry genetic material. The objective was to compare four protocols for cryopreservation of guinea fowl sperm (slow and fast programmable, freezing in nitrogen vapor, and pellet) and three cryoprotectants (...

Histomorphology of Thymus Gland in Guinea Fowl (Numida meleagris)

The thymus gland is a lymphoid tissue derived from III and IV pharyngeal pouches. It is the source of stem cells that migrate to other lymphoid organs and participate in immune reactions (Kent, 1978). The thymus gland is regarded immunologically as a primary or central lymphoid organ and its presence is essential for the development of peripheral lymphoid tissues and their associated adaptive i...
