prevalence and distribution of aeromonas hydrophila in the united states.the abundance of aeromonas hydrophila was measured in 147 natural aquatic habitats in 30 states and puerto rico. viable cell counts were used to estimate density at all sites by using rimler-shotts medium, a differential presumptive medium for a. hydrophila. temperature, ph, conductivity, salinity, and turbidity were measured simultaneously with water sample collection. the density of a. hydrophila was higher in lotic than in lentic systems. saline systems had higher densities of a. hydrophila t ...197831839
bacterial flora of the schistosome vector snail biomphalaria glabrata.the aerobic heterotrophic bacterial flora in over 200 individuals from 10 wild populations and 3 laboratory colonies of the schistosome vector snail biomphalaria glabrata was examined. internal bacterial densities were inversely proportional to snail size and were higher in stressed and laboratory-reared snails. the numerically predominant bacterial genera in individual snails included pseudomonas, acinetobacter, aeromonas, vibrio, and several members of the enterobacteriaceae. enterobacteriacea ...1979539821
associated bacterial flora, growth, and toxicity of cultured benthic dinoflagellates ostreopsis lenticularis and gambierdiscus toxicus.the growth, toxicity, and associated bacterial flora of 10 clonal cultures of the toxic benthic dinoflagellates ostreopsis lenticularis and gambierdiscus toxicus isolated from the coastal waters of southwest puerto rico have been examined. clonal cultures of o. lenticularis grew more rapidly and at broader temperature ranges than those of g. toxicus. all five ostreopsis clones were toxic, while only one of the five gambierdiscus clones was poisonous. the degree of toxicity among poisonous clones ...19892705766
