The effect of natural inactivation in freshwater, chlorination, ammonia, extreme pHs, temperature, and salt content on phage inactivation was evaluated on mixtures of F-specific RNA bacteriophage isolates belonging to genotypes I, II, III, and IV. The bacteriophages studied were previously but recently isolated from natural samples, characterized as(More)
AIMS To assess whether the distribution of genotypes of F-specific RNA bacteriophages reflects faecal pollution of human and animal origin in water environments. METHODS AND RESULTS Stool samples, animal feedlot waste slurries and a wide variety of faecally polluted waters were studied in South Africa and Spain. Genotyping was performed by plaque and spot(More)
The performance of Salmonella typhimurium WG49 and Escherichia coli HS(pFamp)R was compared on detecting the different genotypes of F-specific RNA bacteriophages by plaque hybridisation. The sensitivity of this assay was also compared with the sensitivity of RT-PCR followed by Southern blotting for detecting F-specific RNA bacteriophages belonging to(More)
