We describe a new species of extinct duck, Miotadorna catrionae sp. nov. (Anatidae, Tadornini, Tadorninae), based on right humerus from the Miocene lacustrine deposits St Bathans, Otago, New Zealand. Principal component analysis reveals that taxon is distinguished by its large size and relative proportions. This eighth largest duck described Bathans fossil assemblage further underscores global ...

b ackground: cercarial dermatitis is known as an endemic parasitic disease in north of iran, a hy- persensitive skin reaction to the penetration of nonhuman schistosome larvae into human skin. in recent studies in this region, final and intermediate hosts were recognized and trichobilharzia was identified as the main causative agent of cercarial dermatitis in this region, but to date the parasi...

The icosahedral virion of duck enteritis virus (DEV) is roughly spherical and approximately 150 nm in diameter. Here, we describe the genomic features of DEV CHv together with a draft genome sequence and its annotation, highlighting the homogeneity and heterogeneity of this genome in comparison with its reference genomes.

Here, we present the complete genome sequence of an attenuated duck enteritis virus (DEV) obtained by serial chicken embryo passage. Compared with a virulent DEV, there is a serial deletion in unique long open reading frame 11 (LORF11) and unique long region 2 (UL2). This study will aid in further exploration of the molecular pathogenesis of DEV.

The anomaly P is a widespread morphological anomaly, which occurs in some groups of amphibians, caused by the trematode parasite Strigea robusta (Digenea: Strigeidae). This has been previously recorded water frogs genus Pelophylax and toads genera Bufo Bufotes . includes symmetrical polydactyly cases as mild attenuated form complex syndrome, severe strong deformations hindlimbs forelimbs. 3-hos...
