The precise microenvironment of Paracoccidioides brasiliensis has not yet been discovered perhaps because the methods used are not sensitive enough. We applied to this purpose the polymerase chain reaction (PCR) using three sets of specific primers corresponding to two P. brasiliensis genes. This fungus as well as several other fungi, were grown and their DNA obtained by mechanical disruption a...

Zinc finger nuclease (ZFN) is a useful tool for endogenous site-directed genome modification. The development of an easier, less expensive and repeatedly usable construction method for various sequences of ZFNs should contribute to the further widespread use of this technology. Here, we establish a novel construction method for ZFNs. Zinc finger (ZF) fragments were synthesized by PCR using shor...

Feline panleukopenia (FP) is a severe viral illness caused by the feline virus (FPV), putting sectors like companion cat breeding and endangered conservation at risk. The has high morbidity fatality rate found all over world. We created novel FPV assay using nanoPCR technology assessed method’s specificity sensitivity. approach amplified 345 bp nucleic acid fragment with minimum detection limit...

aim : we aimed to develop a multiplex pcr assay for specific detection of epec and ehec pathotypes based on specific marker genes. background : about 2.5 million infant’s morbidity in developing countries occurs by e.coli pathotypes because of diarrhea and intestinal diseases. the traditional phenotypic methods are time consuming and sometimes detection and differentiation of the pathotypes are...

The TaqMan® SNP genotyping technology utilizes the 5’ nuclease activity of Taq polymerase to generate a fluorescent signal during PCR. For each SNP, the assay uses two TaqMan probes that differ in sequence only at the SNP site, with one probe complementary to the wild-type allele and the other to the variant allele. The technique utilizes the FRET technology whereby a 5’ reporter dye and a 3’ q...

Recent reports have indicated that digital PCR may be useful for the noninvasive detection of fetal aneuploidies by the analysis of cell-free DNA and RNA in maternal plasma or serum. In this review we provide an insight into the underlying technology and its previous application in the determination of the allelic frequencies of oncogenic alterations in cancer specimens. We also provide an indi...

BACKGROUND Profiling of the immune receptor repertoire is becoming increasingly relevant to the understanding and clinical management of cancer, autoimmunity, aging, and infectious disease. FINDINGS A platform technology is described that provides comprehensive immune receptor profiling. CONCLUSION Immunosequencing is a platform technology that allows the enumeration, specification and quan...

Background: Chest computed tomography (CT) is a recommended screening and assessment tool for patients with suspected coronavirus disease (COVID-19). However, CT units are currently not available in many temporary hospitals centralized isolation places. Objectives: To delineate the workflow of mobile unit evaluate its role COVID-19 infection locations. Patients Methods: Two hundred twenty-three...

Rapid and accurate identification of mastitis pathogens is important for disease control. Bacterial culture and isolate identification is considered the gold-standard in mastitis diagnosis but is time-consuming and results in many culture-negative samples. Identification of mastitis pathogens by PCR has been proposed as a fast and sensitive alternative to bacterial culture. The results of bacte...

The use of the polymerase chain reaction (PCR) in molecular diagnostics has increased to the point where it is now accepted as the gold standard for detecting nucleic acids from a number of origins and it has become an essential tool in the research laboratory. Real-time PCR has engendered wider acceptance of the PCR due to its improved rapidity, sensitivity, reproducibility and the reduced ris...
