Detection and enumeration of Cryptosporidium oocysts in environmental water samples by Real-time PCR assay
Introduction: The protozoan parasite, Cryptosporidium Spp., widely spreads in both raw and drinking waters. It is the causative agents of waterborne diarrhea and gastroenteritis in the world. In the present study, a molecular assay was used for the detection and quantification of Cryptosporidium oocysts in environmental water samples. Materials and methods: Thirty surface water samples wer...
متن کاملDetection of methanotrophic bacteria in environmental samples with the PCR.
We designed PCR primers by using the DNA sequences of the soluble methane monooxygenase gene clusters of Methylosinus trichosporium OB3b and Methylococcus capsulatus (Bath), and these primers were found to be specific for four of the five structural genes in the soluble methane monooxygenase gene clusters of several methanotrophs. We also designed primers for the gram-negative methylotroph-spec...
متن کاملViability PCR, a culture-independent method for rapid and selective quantification of viable Legionella pneumophila cells in environmental water samples.
PCR-based methods have been developed to rapidly screen for Legionella pneumophila in water as an alternative to time-consuming culture techniques. However, these methods fail to discriminate between live and dead bacteria. Here, we report a viability assay (viability PCR [v-PCR]) for L. pneumophila that combines ethidium monoazide bromide with quantitative real-time PCR (qPCR). The ability of ...
