Nucleocapsid (N) protein of infectious bronchitis virus (IBV), one of the viral structural proteins, inducesstrong antibody response in natural infection. In this study, a simple, recombinant N protein-based dot-blottest was developed to serologically examine chicken serum samples for the presence of IBV antibody.Initially, 72 serum samples were tested for the presence of IBV antibody using a c...
The polymerase chain reaction (PCR) was investigated for detecting human parvovirus B19 (B19) DNA in sera. Three pairs of oligonucleotides were evaluated as primers. The best oligonucleotide pair spanned 699 nucleotides, including the region common to VP1 and VP2. After PCR amplification of B19 DNA in serum, a 699-nucleotide DNA fragment was detected on agarose gels. This DNA fragment was B19 D...
Strawberry mottle virus (SMoV) is one of the viral pathogens affecting strawberries (Fragaria spp.) production severely worldwide. Currently, reverse transcription-polymerase chain reaction (RT-PCR) is frequently used to detect SMoV, which is sometimes not successful because of unsatisfied nucleic acid quality and the contamination of secondary metabolites resulting in poor PCR amplification. I...
Development of rapid molecular approaches for pathogen detection is key to improving treatment of infectious diseases. For this study, the kinetics and temperature-dependence of DNA probe hybridization to uropathogen species-specific sequences were examined. A set of oligonucleotide probes were designed based on variable regions of the 16S gene of the Escherichia coli, Proteus mirabilis, Klebsi...
background: aflatoxin b1 (afb1) is a toxic metaboliteproduced by aspergillus species that contaminates a wide range ofagricultural products. objectives: this study was designed todevelop a rapid and highly sensitive immunoassay method inmicroarray format for quantitative detection of afb1 to evaluatethe potential of microarray platform for high-throughput screening,which can be beneficial in fo...
