By using in situ hybridization and immunohistochemistry, the distribution patterns of heme oxygenase (HO)-1 (HSP32) transcript and protein were studied, and their response to thermal stress was examined. And, by using an HO-1 cDNA probe and polyclonal antibody, the levels of HO-1 mRNA and protein in
In this study, a new in situ hybridisation (ISH) protocol has been developed to identify African swine fever virus (ASFV) genome in formalin-fixed, paraffin-embedded tissues. Different digoxigenin labelled ASFV-probes were tested, including single ASFV-specific oligonucleotides, an 18.5kb
BACKGROUND
Yellow fever virus continues to cause major epidemics. A sensitive rapid diagnostic test is required to identify cases and contacts in order to implement emergency immunization campaigns.
OBJECTIVE
To identify YFV envelope protein gene fragments, construct a polymerase chain reaction
In situ hybridization (ISH) has become a very valuable molecular diagnostic tool to detect specific DNA or RNA sequences in biological samples through the use of complementary DNA- or RNA-labeled probes. Here, we describe an optimized in situ hybridization protocol to detect African swine fever
A combined staining of immunohistochemistry and in situ hybridization has been successfully applied to detect antigen and viral RNA at the same tissue slice from epidemic hemorrhagic fever (EHF) autopsy. Multiple McAb were used to detect EHFV antigen, followed with a digoxigenin-labelling cDNA probe
Hemorrhagic fever virus (HFV) RNA in renal tissue and blood samples from 21 patients with epidemic hemorrhagic fever with renal syndrome (HFRS) were examined by either in situ or blot hybridization using digoxigenin labelled HFV-cDNA probe. HFV associated antigen and immune complex (IC) in renal
Neural expression of constitutive hsc70 mRNA and hyperthermia-inducible hsp70 mRNA is examined using radioactive and non-radioactive in situ hybridization procedures. A strong induction of hsp70 mRNA was noted in cell populations in cerebellar layers and in the brainstem which demonstrated
A polymerase chain reaction (PCR) assay was developed for the detection of alcelaphine herpesvirus 1 (AHV1), a causative agent of malignant catarrhal fever (MCF) of ruminants. A pair of 20-base primers was constructed based on the published nucleotide sequence of gene A of the WC11 isolate of AHV1
Rapid, sensitive and specific laboratory diagnostic methods are necessary to confirm outbreaks of classical swine fever. The detection of classical swine fever virus (CSFV) and its discrimination from other pestiviruses can be achieved by virus isolation on cell culture, antigen detection, or
BACKGROUND
The aim of this study was to compare the tissue distribution and pathogenicity of three virulence variants of classical swine fever virus (CSFV) and to investigate the applicability of various conventional diagnostic procedures.
METHODS
64 pigs were divided into three groups and infected
A fusion protein encompassing Gly341 of the skeletal muscle ryanodine receptor was used to raise monoclonal antibodies; epitope mapping demonstrates that monoclonal antibody 419 (mAb419) reacts with a sequence a few residues upstream from Gly341. The mAb419 was then used to probe ryanodine receptor
BACKGROUND
Hantaviruses cause two serious human diseases: hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome. At least nine hantaviruses are known to be pathogenic for humans and numerous others, with unknown disease potential, have been detected in rodents. Assays to quickly
OBJECTIVE
To apply an automated system of nucleic acid hybridisation coupled with the enzyme linked immunosorbent assay (ELISA) for the type specific detection of amplification products of dengue viruses.
METHODS
Non-structural 3 (NS3) gene targets of reference strains of all four dengue and other
Two Borrelia isolates (CA434 and CA435) cultured from the soft tick Ornithodoros coriaceus were analyzed by contour-clamped homogeneous electric field gel electrophoresis of unrestricted and ApaI-restricted DNA, standard electrophoresis of BamHI- and HindIII-restricted DNA, Southern hybridization,
By extending functional primers attached to a solid phase and incorporating a digoxigenin label, it is possible to visualise PCR products as discrete spots on specific regions of a solid support after colorimetric detection. The technique has been used for the detection of the point mutation
