adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. in spite of their usefulness, the construction of adenoviral vectors (adv) is a cumbersome and lengthy process that is not readily amenable to the generat...
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...
The work which is here reported was undertaken in part as an extension of our previous observations on the behavior of pox viruses in the respiratory tract (1, 2) and in part to determine whether or not fowl pox virus was capable of simulating the clinical syndrome of chickens referred to as roup. Roup, which is also known by a variety of names as infectious catarrh, infectious rhinitis, and fo...
background: the loop pattern of the small intestine is of considerable importance in categorizing them and the intestine length of the two sex is different. in this respect there is no research performed on pheasant family as guinea fowl. objectives: in this research histomorphology of guinea fowl's small intestine was studied. methods: for this study 20 adult male and female guinea fowls ...
Studies with captive fowl have revealed that they possess greater cognitive capacities than previously thought. We now know that fowl have sophisticated cognitive and communicative skills, which had hitherto been associated only with certain primates. Several theories have been advanced to explain the evolution of such complex behavior. Central to these theories is the enlargement of the brain ...
