Resultados: A semi-nested PCR foi positiva para quatro amostras e negativa para a amostra de um paciente, posteriormente diagnosticado com leishmaniose. To avoid this problem, we have used semi‐nested PCR to improve the specific amplification, and developed the method called TSAT‐PCR. In general, nested or semi-nested PCR assays performed in a single tube are less sensitive when compared with assays that take place in two stages and in separate tubes 11-13.However, in our study, we achieved the same limit of detection for the OTsn-PCR assay as the semi-nested PCR approach described by Koishi et al. 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 … "comments": true, CONTRI, A.

"openAccess": "0", Thus, we developed a new semi-nested PCR system based on the initial amplification of over 1,700 bp of the 18S rRNA gene with a new primer combination, followed by a subsequent amplification with NS1/FR1-GC. In this study we tested the reliability and suitability of the previously published fungal primer combination (NS1/FR1-GC) that amplifies almost the entire 18S rRNA gene for the DGGE analysis of fungal communities in soil samples from 36 sites. 2009. and The first primer pair A set amplifies within the locus. 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. In this method, two pairs of PCR primers are designed: one set (outer primers) flanks a region of DNA containing the amplicon of interest, while a second set (nested primers) corresponds to the precise region of DNA to be amplified.

AS‐PCR combined with semi‐nested PCR was successfully used to identify the mtDNA control region of each contributor, providing biological evidence for excluding suspects in forensic cases, especially when biological materials were degraded or had a limited amount of DNA. and and 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). Rondolotti, Anna The specificity of the assay was also tested using a panel of control DNA samples representing horse, the gastric spirurid Draschia megastoma and 26 other species of parasites from the alimentary tract of the horse. 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. With recent technological advances, several platforms are available to implement digital PCR in a clinical setting. 2010;25(4):281-7. doi: 10.1264/jsme2.me10136. This was extracted with the Sinnagene extraction kit.

The nested amplification format increases the sensitivity substantially, rivaling that of nested 5′-NTR assays ( 4 , 10 ), so that nested VP1 assays can be used for both detection and identification. A semi nested PCR is a way to get amplification of a target sequence by using two consecutive PCR runs. This direct PCR system failed to amplify the fragment of interest from the total DNA extracted from most of the soils tested.
