We report here the complete genome sequence of an avian metapneumovirus (aMPV) isolated from a tracheal tissue sample of a commercial layer flock. The complete genome sequence of aMPV-A/chicken/Brazil-SP/669/2003 was obtained using MiSeq (Illumina, Inc.) sequencing. Phylogenetic analysis of the complete genome classified the isolate as avian metapneumovirus subtype A.
Balansia epichloe (Weese) and B. henningsiana (Moell.) were isolated from grasses in toxic fescue pastures. B. epichole, cultured in a synthetic medium, was toxic to chicken embryos. Thin-layer chromatography and ultraviolet absorption data indicated that in submerged culture the fungus produced compounds with the indole or ergoline nucleus.
The present study demonstrates that the biosynthesis of phospholipids in the inner nuclear layer cells of the chicken retina displays daily rhythms under constant illumination conditions. The vertebrate retina contains circadian oscillators and photoreceptors (PRCs) that temporally regulate its own physiology and synchronize the whole organism to the daily environmental changes. We have previou...
The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...
A method was developed to determine the survival of Campylobacter jejuni at specific sites on chicken skin, and this method was used to observe the survival of C. jejuni at various locations on the skin during storage. This method uses confocal scanning laser microscopy to visualize C. jejuni transformed with P(c)gfp plasmid (GFP-Campylobacter) and stained with 5-cyano-2,3-ditolyl tetrazolium c...
The chicken leptin sequence, in contrast to mammalian leptins, contains an unpaired Cys at position 3 of the original cDNA (AF012727). The presence of an extra Cys may confer a different structure and affect the leptin's biological activity. To address this, we studied the effects of wild-type and mutated (C4S) chicken leptins in vitro and in vivo and compared them with mammalian leptin prepare...
