Development of a Real-Time Reverse-Transcription PCR for Detection of Newcastle Disease Virus RNA in Clinical Samples
A positive correlation was obtained between the RRT-PCR results and virus isolation for NDV from clinical samples, and a real-time reverse-transcription PCR test was developed to detect avian paramyxovirus 1 (APMV-1) RNA in clinical samples from birds. Expand
Pathogenesis of Newcastle Disease in Chickens Experimentally Infected with Viruses of Different Virulence
Compromise of air sac and myocardium may predispose mesogen- and lentogen-infected chickens to secondary infection and/or decreased meat and egg production. Expand
Isolation of a Lactobacillus salivarius Strain and Purification of Its Bacteriocin, Which Is Inhibitory to Campylobacter jejuni in the Chicken Gastrointestinal System
Bacteriocin from L. salivarius NRRL B-30514 appears potentially very useful to reduce C. jejuni in poultry prior to processing, and had sequence similarity, even in the C-terminal region, to acidocin A, which was previously identified fromL. Expand
Matrix protein gene nucleotide and predicted amino acid sequence demonstrate that the first US avian pneumovirus isolate is distinct from European strains.

Avian pneumovirus (APV) is the etiological agent of turkey rhinotracheitis (TRT). Outbreaks of TRT first occurred in the US during May, 1996 and continued through June, 1997. This is the first reportExpand
Experimental Pathogenesis for Chickens, Turkeys, and Pigeons of Exotic Newcastle Disease Virus from an Outbreak in California during 2002-2003
Evidence of CA END virus subclinical infections that suggest pigeons could be subclinical carriers of other virulent NDV are provided, and susceptibility to highly virulentNDV was shown to vary among chickens, SPF turkeys, commercial turkeys and pigeons. Expand
Characterization of Newcastle disease virus isolates by reverse transcription PCR coupled to direct nucleotide sequencing and development of sequence database for pathotype prediction and molecular
Differences in the fusion protein cleavage sequence that correlated genotypically with virulence among various NDV pathotypes were detected and lentogenic viruses were grouped phylogenetically separate from other pathotypes by using sequences generated from the matrix protein gene coding for the nuclear localization signal.

Molecular Characterization of an Avian Astrovirus
The nucleotide sequence, genomic organization, and predicted amino acid sequence of a turkey astrovirus isolated from poults with an emerging enteric disease is reported. Expand
The epidemiology of antibiotic resistance in Campylobacter.
This review examines the clinical epidemiology of antibiotic resistance in human and animal thermophilic campylobacters, an update on resistance rates globally, and surveillance of antimicrobial resistance in campylolobacters originating from animals, particularly poultry. Expand
Pathogenesis of Six Pigeon-Origin Isolates of Newcastle Disease Virus for Domestic Chickens
The clinical signs and gross and histopathologic changes observed in the APMV-1-infected birds were characteristic of an extensive infection with highly virulent NDV evident by IHC. Expand
Isolation and Purification of Enterocin E-760 with Broad Antimicrobial Activity against Gram-Positive and Gram-Negative Bacteria
The proteinaceous nature of purified enterocin E-760 was demonstrated upon treatment with various proteolytic enzymes, and the antimicrobial peptide was found to be sensitive to beta-chymotrypsin, proteinase K, and papain, while it was resistant to lysozyme and lipase. Expand
