| The Perequê and Penedo rivers flow through the plains of Praia de Leste and fall into the sea between the municipalities of Pontal do Sul and Ponta do Poço. Both of these rivers belong to the sub-basin of Paranaguá Bay, and are constituent parts of the hydrographic basin of the Atlantic Ocean (State of Paraná). Four sites along the Perequê River (Stations 1-4) and one along the Penedo River (Station 5) were monitorated for water pollution over a 12-month period. During the period of December 1995 to November 1996, three water samples were collected from each site, placed in sterilized bottles and transported to the laboratory in ice-boxes. They were analyzed for the occurrence of total and fecal coliforms, temperature and pH. Fecal pollution was detected... |

| Readycult - LMX is a rapid method to test for the presence of total coliform bacteria and Escherichia coli in water, giving results in 24h. It is based on reactions of specific microbial enzymes or indicator nutrients of the medium. The goal of this paper was to study the use of Readycult - LMX to detect total coliform and E. coli in milk. One hundred twenty five samples of pasteurized and raw milk, collected in Londrina, PR, Brazil, were tested simultaneously by the most probable number (MPN) method using Brilliant Green Bile Lactose Broth (2%) (BRILA) and Readycult - LMX. The Readycult - LMX test was evaluated for sensitivity, simplicity, and speed of results. There was a significant correlation between the results obtained by the two methods for... |
