Abstract Aims: To assess norovirus (NoV) contamination in aquatic ecosystems in the city of Florianópolis, in Southern Brazil, in order to provide epidemiological data that can support actions for environmental contamination control. Methods and Results: An adsorption‐elution method, followed by ultrafiltration, was performed to concentrate the viruses. NoV were detected using semi‐nested PCR...

Abstract Aims: This study aimed to compare the efficacy of different disinfection methods in eliminating Salmonella contamination from turkey houses. Methods and results: Fifty depopulated turkey houses which had all housed Salmonella‐positive flocks were visited after cleaning and disinfection. A minimum of 45 swab samples from different surfaces were taken per house and analysed for the...

Abstract Aims: To develop simple and rapid PCR‐fingerprinting methods for Vibrio cholerae O1 (El Tor and classical biotypes) and O139 serogroup strains which cause major cholera epidemics, on the basis of the diversity of superintegron (SI) carried by these strains. Methods and Results: PCR‐restriction fragment length polymorphism (PCR‐RFLP) assay was developed targeting region between...
