Sensitivity Detection

The main objective of this study was to make sure whether randomly taken 12 samples were sensitive to abacavir. The genomic DNA from 12 blood sample were extracted by phenol chloroform DNA extraction method, extracted genomic DNA were amplified and sequenced, thereafter SNPs were detected. Every sample had shown the presence of normal base at SNP position. This study indicated, those randomly taken 12 patients were sensitive to abacavir, so they can consume abacavir if they get infected with HIV.

AbstractMolecular biology protocols have been more and more accessible to researchers for ecological investigations, however, these protocols always require optimization steps for the analysis of specific types of samples. The purpose of this study was to optimize a molecular protocol for the analysis of cyanobacterial 16S rRNA in Danube Delta shallows lakes. In this regard, several commercial DNA extraction kits were tested in comparison with potassium ethyl xanthogenate extraction method on different matrices. The obtained DNA was further used for 16S rRNA PCR optimization. Finally, an optimized protocol is proposed for the molecular analysis of cyanobacteria group in freshwater samples. The best DNA extraction method was the potassium xanthogenate extraction from dried cyanobacterial biomass. A dynamic in total genomic eDNA was observed, reflecting the seasonal difference in phytoplankton biomass from the studied lakes. The PCR protocol optimized by us can be successfully applied for the identification of a broad range of cyanobacterial genetic markers.

Intestinal Microsporidiosis

ABSTRACT The diagnosis of intestinal microsporidiosis has traditionally depended on direct visualization of the parasite in stool specimens or intestinal biopsy samples by light and/or electron microscopy. Limited information about the specificity and sensitivity of PCR for the detection microsporidia in clinical stool specimens is available. To establish a sensitive and specific method for the detection of microsporidia in clinical samples, we studied clinical stool specimens of 104 randomly selected human immunodeficiency virus-infected patients with diarrhea to compare light microscopy and PCR. Fluorochrome Uvitex 2B staining was used for light microscopy. To raise the sensitivity of PCR, we used a powerful and fast DNA extraction method including stool sedimentation, glass bead disruption, and proteinase K and chitinase digestion. PCR was performed with primer pairs V1-PMP2, V1-EB450, and V1-SI500, and the nature of the PCR products was confirmed by Southern blot hybridization. Microsporidiosis was diagnosed by light microscopy in eight patients. Ten patients tested positive for microsporidiosis by PCR. Enterocytozoon bieneusi was found in seven cases, andEncephalitozoon intestinalis was found in four cases. In one case a double infection with E. bieneusi and E. intestinalis was diagnosed by PCR, whereas light microscopy showed only E. bieneusi infection. PCR testing of stool specimens is useful for diagnosis and species differentiation of intestinal microsporidiosis in HIV patients.
