Variable Freshwater Influences on the Abundance of in a Tropical Urban Estuary.

To better understand the controls on the opportunistic human pathogen Vibrio vulnificus in warm tropical waters, we conducted a year-long investigation in the Ala Wai Canal, a channelized estuary in Honolulu, HI. The abundance of V. vulnificus, as determined by quantitative PCR (qPCR) of the hemolysin gene (), varied spatially and temporally by nearly 4 orders of magnitude (≤3 to 14,000 mL).
