In Southwest Florida over the past week, K. brevis was observed at background and very low concentrations in Sarasota County, and background to medium concentrations in Charlotte, Lee, and Collier counties. Bloom concentrations (>100,000 K. brevis cells per liter) were observed in 7 samples from estuarine sites in Charlotte and Lee counties, and 3 samples from coastal or inlet sites in Collier County. High concentrations (>1 million K. brevis cells per liter) were not observed over the past week.
