background and objectives: pcr is a sensitive assay and could be used as an accurate diagnostic method for detecting various types of microorganisms' genome in low concentration in biological specimens. the demand for sensitive, rapid, safe and easy detection of pcr products has led researchers to a combination of this method with elisa. materials and methods: conserved sequences were selected ...

We established a new highly sensitive method, PCR-ELISA, for the dectection of Babesia bovis in cattle for farms in Thailand. The detection of around 2.4 x 10(-8)% parasitemia (equivalent to 1 infected erythrocyte per 2 ml) was achieved by PCR amplification followed by the ELISA detection of a biotin tagged gene. When comparing the sensitivity of PCR-ELISA with the microscopic method, our PCR-E...

The bacterium Coxiella burnetii has been associated with reproduction disorders in dairy cattle. A cross-sectional study was conducted Quebec, Canada, to estimate the prevalence of C. cows from RT-PCR-positive and/or ELISA-positive herds. As a secondary objective, associations between burnetii-positivity and three reproductive outcomes (purulent vaginal discharge, cytological endometritis, succ...

Contamination of retail poultry by Campylobacter spp. and Salmonella enterica is a significant source of human diarrheal disease. Isolation and identification of these microorganisms require a series of biochemical and serological tests. In this study, Campylobacter ceuE and Salmonella invA genes were used to design probes in PCR-enzyme-linked immunosorbent assay (ELISA), as an alternative to c...


 The present study aimed to assess enzyme-linked immunosorbent assay (ELISA) and nested-polymerase chain reaction (n-PCR) methods based on B1 gene for the detection of Toxoplasma (T.) gondii in blood milk local Iraqi goats. SAG3 was also used identify genotyping T. goats aborted women Iraq. A total 240 (80 blood, 80 sera, milk) lactating 30 samples from were included this study. 17 (21.2%...

Foot-and-mouth disease (FMD) is one of the highly contagious diseases of domestic animals. Effective control of this disease needs sensitive, specific, and quick diagnostic tools. In this paper seventy suspected field's samples to FMD were analyzed using virus isolation on cell culture, Enzyme Linked Immunosorbant Assay (ELISA), RT-PCR (Reverse TranscriptionPolymerase Chain Reaction) and PCR-EL...

Polymerase chain reaction-enzyme linked immunosorbent assay (PCR-ELISA) is an immunodetection method that can quantify PCR product directly after immobilization of biotinylated DNA on a microplate. This method, which detects nucleic acid instead of protein, is a much more sensitive method compared to conventional PCR method, with shorter analytical time and lower detection limit. Its high speci...
