The use of DNA sequences of diverse genetic loci has revolutionized our understanding of the systematic relationships among many different organisms. One such unexpected discovery was that two African galliform species, the Stone Partridge Ptilopachus petrosus Gmelin, 1789, and Nahan’s Francolin Francolinus nahani Dubois, 1905, represent a relictual clade sister to the New World Quail (Odontoph...

Cabot's tragopan, Tragopan caboti, is a globally threatened pheasant endemic to southeast China. The complete mitochondrial genome of Cabot's tragopan was sequenced. The circular genome contains 16,727 bp, encoding a standard set of 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes, plus the putative control region, a structure very similar to that of other Galliformes...

background and aims: influenza a virus infects birds and some mammalian including human. h1 and h3 subtypes are circulated in both human and birds’ population. to determine the prevalence of the mentioned subtypes in birds, different captive bird species in tehran zoo, and affiliated centers in tehran were investigated for virus infection. methods: in this study, between november 2008 and febru...

Influenza A virus is always concerned as an infectious agent in birds and other mammalian such as humans. Although it is believed that barriers among various species restrict the transmission of influenza viruses, there are evidences implying that origin of all human influenza viruses is derived from avian influenza viruses. To determine the prevalence of human H1 and H3 viruses in the captive ...
