Modified Pseudomonas agar: new differential medium for the detection/enumeratio...
Ramalho, Rita; Cunha, Joaquim; Teixeira, Paula; Gibbs, Paul A.Pseudomonas aeruginosa has been implicated as a foodborne and waterborne pathogen and is now considered a primary infectious agent. In the present study, the survival of P. aeruginosa inoculated in mineral water was evaluated by drop counts on Pseudomonas Agar Base (PAB), PAB with CN supplement X107, PAB with cetrimide, PAB with nalidixic acid, and these media with added FeSO4. Initial counts, before starvation...
Improved methods for the enumeration of heterotrophic bacteria in bottled miner...
Ramalho, Rita; Cunha, Joaquim; Teixeira, Paula; Gibbs, Paul A.At this time the European Union regulations require that the heterotrophic plate counts (HPC) of mineral waters be assessed at two recovery temperatures: 22°C for 72 h and 37°C for 24 h. This procedure is time consuming and expensive. Development of new rapid methods for microbiological assessment of the microbial flora in the bottled water is an industry-driven need. The objectives of this work were to develop...
Survival characteristics of pathogens inoculated into bottled mineral water
Ramalho, Rita; Afonso, Anita; Cunha, Joaquim; Teixeira, Paula; Gibbs, Paul AnthonyTo assess the risk of contracting a waterborne disease from mineral water and to implement control systems in the mineral water industry, knowledge of the factors affecting the survival and multiplication of non-indigenous bacteria is needed. The survival of Escherichia coli, Salmonella typhimurium, Staphylococcus aureus and Yersinia enterocolitica inoculated into a Portuguese bottled mineral water was investig...
Evaluation of survival patterns and cellular injury of pseudomonas aeruginosa i...
Teixeira, Paula; Cunha, Joaquim; Albano, Helena; Ramalho, Rita; Gibbs, PaulPseudomonas aeruginosa cells were inoculated into different waters and sampled after different periods of starvation in order to evaluate the influences of storage under daylight or dark conditions, the presence or absence of the autochthonous flora, the chemical composition of the water and the storage temperature, on survival Survival was investigated by plate counts on selective and nonselective agar media. ...
