| survey of peafowl (pavo cristatus) for potential pathogens at three michigan zoos. | blood samples collected from 31 free-roaming peafowl from three zoos in michigan were tested serologically. antibody titers were present against avian adenovirus and bordetella avium in 19.3% and 61.3% of the samples, respectively. serum plate agglutination tests were positive for mycoplasma meleagridis and mycoplasma synoviae in 3.2% and 38.7% of the samples, respectively. all birds were seronegative for avian influenza, newcastle disease virus, west nile virus, mycoplasma gallisepticum, salmon ... | 2003 | 15077714 |
| pathotyping of a newcastle disease virus isolated from peacock (pavo cristatus). | this report describes newcastle disease in peacock and the isolation and characterization of the virus. the virus had an intracerbral pathogenicity index of 1.71 and mean death time of 47 h. the isolate had multiple basic amino acids at the fusion protein cleavage site sequence ((110)ggrrqrrfig(119)) with a phenylalanine at residue 117. biological and molecular characterization revealed that the virus is velogenic. phylogenetic analysis placed the isolate in genotype ii. | 2010 | 19763869 |
| molecular characterization, isolation, pathology and pathotyping of peafowl (pavo cristatus) origin newcastle disease virus isolates recovered from disease outbreaks in three states of india. | disease outbreak investigations were carried out in three states of northern india namely haryana (rewari), uttar pradesh (noida) and delhi, where a total of 110 indian peafowls (pavo cristatus) showed sudden onset of nervous signs and died within a period of two weeks during june, 2012. the f (fusion) gene-based rt-pcr detection of newcastle disease virus (ndv) in affected tissues confirmed the presence of the virus. three ndv isolates were selected (one from each area under investigation) and ... | 2016 | 27724072 |
| characterization and sequencing of a genotype xii newcastle disease virus isolated from a peacock (pavo cristatus) in peru. | here, we report the first complete sequence and biological characterization of a newcastle disease virus (ndv) isolated from a peacock in south america (ndv/peacock/peru/2011). this isolate, classified as genotype xii in class ii, highlights the need for increased surveillance of noncommercial avian species. | 2015 | 26227592 |
| complete genome sequence of a newcastle disease virus isolated from wild peacock (pavo cristatus) in india. | we report here the complete genome sequence of a newcastle disease virus (ndv) isolated from a wild peacock. phylogenetic analysis showed that it belongs to genotype ii, class ii of ndv strains. this study helps to understand the ecology of ndv strains circulating in a wild avian host of this geographical region during the outbreak of 2012 in northwest india. | 2014 | 24903868 |
| detection and molecular characterization of newcastle disease virus in peafowl (pavo cristatus) in haryana state, india. | present study was undertaken to investigate the cause of deaths of peafowls in haryana state. in total, 145 birds were sick and 28 birds were reported dead during july to september 2012. some of the sick birds were showing signs of shaking of heads, torticollis and paresis. blood and cloacal swab samples from sick birds along with brain and intestinal tissues from dead birds were collected for further investigation. although post-mortem examination showed no typical lesions of newcastle disease ... | 2013 | 24426301 |
| complete genome sequence of a velogenic neurotropic avian paramyxovirus 1 isolated from peacocks (pavo cristatus) in a wildlife park in pakistan. | avian paramyxovirus serotype 1 (apmv-1) was isolated from an acute and highly contagious outbreak in peacocks (pavo cristatus) in a wildlife park in pakistan. a velogenic neurotropic form of apmv-1 caused a 100% case fatality rate and killed 190 peacocks within a week. biological and serological characterizations showed features of a velogenic strain of apmv-1, and these results were further confirmed by sequence analysis of the cleavage site in the fusion protein. the complete genome of one of ... | 2012 | 23118447 |
| molecular characterization and biological activity of interferon-α in indian peafowl (pavo cristatus). | interferon-α (ifn-α) genes have been cloned from a variety of animals, but information about indian peafowl pavo cristatus ifn-α (pcifn-α) has not been reported. in this study, a pcifn-α gene was amplified, which encoded a protein of 193 amino acids with a 26-amino acid signal peptide sharing 72.16-95.70% identity with other avians in aves. after expression in prokaryote, purification, and renaturation, pcifn-α was analyzed for its physicochemical property and antiviral activity. cytopathic inhi ... | 2017 | 28783371 |
