Several PCR assays have been developed to allow EV serotype identification directly from original clinical specimens by nested amplification and sequencing of VP1 (4, 10, 31). The first PCR amplifies a sequence as … 2014 Dec 4;2:11-29. doi: 10.1016/j.bdq.2014.11.002. Query parameters: { Application of modified JDP-DGGE-based molecular genotyping method to predict Acanthamoeba genotype and to analyse community diversity in aquatic environments. Nested PCR is a modification of PCR that was designed to improve sensitivity and specificity. Environ Microbiol. * Views captured on Cambridge Core between September 2016 - 18th December 2020.

Traversa, Donato Nested PCR is a variation of standard PCR that enhances the specificity and yield of the desired amplicons. 2009. A Semi-nested RT-PCR and an internally controlled RT-qPCR assays were developed for detection and quantification of four hantaviruses strains circulating in the Brazilian Amazon: Anajatuba (ANAJV) and Castelo dos Sonhos (CASV) strains of Andes virus (ANDV) species; and Rio Mamoré (RIOMV) and Laguna Negra (LNV) strains of LNV species.

For setting up the multiplex semi-nested PCR the samples were made up of a serial dilution of tachyzoites in normal urine, so that the DNA of a sample contained about 2 parasites per micro liter. To avoid this problem, we have used semi‐nested PCR to improve the specific amplification, and developed the method called TSAT‐PCR. Traversa, Donato Traversa, Donato Although index and reference tests were not carried out at the same time, they were performed on the same samples which were collected at the same moment during the disease progression of each patient. and Amplification tests with 101 soil fungal isolates showed that with the new semi-nested system 18S rRNA gene fragments could be obtained from more fungi than with the direct approach. "clr": false, Diversity and ecology of soil fungal communities: increased understanding through the application of molecular techniques. Pellegrini, Duccio Babiker, Heitham Epub 2017 Jun 26. Otranto, Domenico PCR-RFLP was also used to differentiate Theileria lestoquardifrom Theileria an- nulatain positive samples of ticks. The subsequent DGGE separation of community amplicons resulted in a high resolution and revealed reproducible complex soil fungal communities specific for each site, despite a minor variability between replicates of the same sample. eCollection 2014 Dec.

Traversa, Donato Sivakumar, Saritha To overcome this constraint, a two-step, semi-nested PCR-based assay was validated (utilizing genetic markers in the nuclear ribosomal DNA) for the specific amplification of H. microstoma or H. muscae DNA from the faeces from horses (n =46) whose gastrointestinal parasite status had been determined at autopsy and whose faeces were examined previously using a conventional … Using one of the desired amplicons of PCR designed to increase the sensitivity and specificity the.
