Cholera outbreak is more common in developing countries. The causative agent of the disease is Vibrio cholerae strains O1 and O139. Traditional diagnostic testing for Vibrio is not always reliable, because Vibrio can enter a viable but non cultivable state. Therefore, nucleic acid-based tests have emerged as a useful alternative to traditional enrichment testing. In this investigation, a triple...

Purified total genomic DNA labeled with photobiotin was used as a probe for the identification and differentiation of strains of Echinococcus granulosus and to distinguish between the morphologically identical eggs of 2 taeniid species. Such biotinylated probes are easily prepared and can be utilized effectively for rapid screening and identification of taeniid isolates by dot and Southern blot...

Infectious bursal disease (IBD) is an economically important viral disease of chickens with worldwide distribution which suppresses the immune system of young chickens. VP2 is the major host-protective protein of infectious bursal disease virus (IBDV). The encoding region of VP2 protein was PCR amplified from a plasmid containing a cDNA fragment of large genomic segment of IBDV, strain D78. Thi...

Objective(s): Enterotoxigenic Escherichia coli (ETEC) strains are one of the primary causes of diarrhea in newborn calves and in humans, pigs, and sheep. IgY technology has been identified as a promising alternative to generating a mass amount of specific antibody for use in immunotherapy and immunodiagnostics. The purpose of this study was to produce specific antibody by egg yolk antibody (IgY...

The plasmid pALCA1SIFN containing cDNA that encodes the human interferon a-2b was obtained from the ATCC(no. 531667). In this system the expression of the gene is under the control of an alcA promoter. alcA p is a specific promoter for expression of different genes in Aspergillusfilamentous. In this plasmid the coding region of IFN?-2b is preceded by the coding region of a synthetic signal ...

introduction lentil is an important pulse crop in iran. lentil is a seed propagating, self-pollinating crop originating from near east. it is containing 27.5% -31.75% protein and it has high level of iron, calcium, phosphor, thiamin, niacin, and some unusual amino acid as hydroxyarnitin, hydroxyarginin and homo arginin. faostat reported that the world production of lentils was 4,975,621 metric ...

Plant diseases caused by viruses are the most menace to sustainable agriculture, leading numerous billion dollars in losses annually. Proper and accurate detection of plant is always key developing appropriate solutions manage economic them. Advances technology have simplified tools available detect diagnose at a time when control measures should be used. Currently, nucleic acid serological bas...
