| prevalence and virulence properties of vibrio cholerae non-o1, aeromonas spp. and plesiomonas shigelloides isolated from cambé stream (state of paraná, brazil). | the incidence of vibrio cholerae, aeromonas spp. and plesiomonas shigelloides was determined in water samples from cambé stream. the samples were collected from seven different sites. the serogroups, virulence markers and drug resistance profiles were also evaluated. twelve aer. hydrophila, 12aer. caviae, eight aer. sobria, seven ple. shigelloides and two v. cholerae non-o1 were isolated. they belonged to different serogroups and all produced haemolysis in different assays. five of the aeromonas ... | 2000 | 10945781 |
| the influence of environmental bacteria in freshwater stingray wound-healing. | invasion by bacteria can influence the course of healing of wounds acquired in aquatic environment. in this study, the bacteria present in potamotrygonmotoro stingray mucus and in the alto paraná river water were identified, and their ability to induce tissue injury and resist antibiotics was determined. biochemical identification analysis showed that 97% of all bacterial isolates were gram negative, aeromonas spp., enterobacter cloacae and citrobacter freundii being the species most prevalent. ... | 2011 | 21635911 |
