MASTER 2 ABSTRACTWater and shellfish samples collected from estuaries, mangroves, -and beaches along the coast of Puerto Rico were examined for Vibrio J vulnificus and Vibrio parahaemolvticus. An array of water quality parameters were also measured simultaneous with bacteria sampling.-Both species of vibrio were associated with estuary and mangrove 3 locations, and neither was isolated from sandy beaches.

Low incidence of Vibrio vulnificus among Vibrio isolates from sea water and shellfish of the western Mediterranean coast

“…1989; Tamplin 1990; Tamplin & Caspers 1992). Its isolation from other geographical areas has also been reported (Rivera et al . 1989; Chuang et al .…”

“…In this study, the incidence of V. vulnificus in the Spanish coastal environment was lower than that described for other geographical zones, despite the fact that the number of culturable Vibrio spp. was similar or even higher (Rivera et al . 1989; O’Neill et al .…”

“…1995). With regard to salinity, an inverse correlation between the presence of V. vulnificus and salinity has been reported (Rivera et al . 1989; Kaspar & Tamplin 1993; Wright et al .…”

Variable freshwater influences on the abundance of Vibrio vulnificus in a tropical urban estuary

“…On a per capita basis, it was the highest in the nation. Despite higher incidence of V. vulnificus wound infections, primarily from recreational waters, there has been little data collected on Vibrio vulnificus in the coastal waters of Hawaiʻ i (30, 31) and scant data on the ecology of V. vulnificus in tropical waters in general (20). Consequently, we initiated an investigation of the abundance and dynamics of V. vulnificus in the Ala Wai Canal and Harbor.…”

Fenotipificación de cepas de Vibrio mimicus aisladas de agua y productos de la pesca

“…La literatura sugiere que la densidad de los vibrios se correlaciona con los incrementos de salinidad del agua (Joseph et al, 1983); este aumento se atribuye al alto índice de evaporación y la poca precipitación pluvial que existe en los meses de verano (Rivera & Hazen, 1998) como se muestra en los resultados obtenidos (Cuadro 3). Se estima que el intervalo de salinidad óptimo que favorece el crecimiento de los vibrios en la columna del agua oscila entre 16-42 Unidades Practicas de Salinidad (UPS) (Bockemuhl & Triemer, 1974;Joseph, 1974).…”
