متن کاملReverse transcription-PCR analysis of bottled and natural mineral waters for the presence of noroviruses.
A seminested reverse transcription-PCR method coupled to membrane filtration was optimized to investigate the presence of norovirus (NV) RNA sequences in bottled and natural mineral waters. The recovery of viral particles by filtration varied between 28 and 45%, while the limit of detection of the overall method ranged from 6 to 95 viral particles. The assay was broadly reactive, as shown by th...
متن کاملBacteriological quality of bottled water brands in Karachi, Pakistan
In the present study, bacteriological quality of 187 different mineral water bottle brands marketed in Karachi was analyzed from September 2009 to June 2010. All the collected samples were analyzed for the presence of coliform bacteria, fecal coliform bacteria, E. coli, fecal entrococci, P. aeruginosa and total viable plate count (TVPC).

متن کاملBottled aqua incognita: microbiota assembly and dissolved organic matter diversity in natural mineral waters
BACKGROUND Non-carbonated natural mineral waters contain microorganisms that regularly grow after bottling despite low concentrations of dissolved organic matter (DOM). Yet, the compositions of bottled water microbiota and organic substrates that fuel microbial activity, and how both change after bottling, are still largely unknown. RESULTS We performed a multifaceted analysis of microbiota a...
