One hundred gallon samples of estuarine water adjusted to pH 3.5 and final AlCl sub(3) molarity of 0.001 were filtered through tubular Filterite filters of 0.45 mu m porosity. Adsorbed virus was eluted with 1 liter of 10% tryptose phosphate broth, pH 9.5. Primary eluates were concentrated. Twenty-one of 72 samples of water, suspended solids, fluffy sediments and compact sediments collected in different seasons in Galveston Bay yielded rotavirusesASW,Galveston BaydetectionEcologyestuariesGalveston BayMethodologyMicrobial contaminationMicrobiologyPollution detectionQ1 01502 Methods and instrumentsQ2 02442 Methods and instrumentsrecoverySedimentSedimentssuspended solidsUSAviruseswaterCONF
