This study was aimed at evaluating the microbiological quality of mangrove oysters (Crassostrea rhizophorae), collected at a natural oyster bed in the estuary of Cocó river (Fortaleza, Ceará, Brazil). MPN values were used for estimating the total (TC) and fecal (FC) coliforms and Enterococcus spp. TC and FC MPN values in the whole muscle and intervalve liquid ranged from &lt;1.8 to &gt;1,600/g and from &lt;1.8 to 920/g, respectively. The MPN estimates for Enterococcus spp. were between &lt;3.0 and &gt;1,100/g. No correlation was found between the physico-chemical parameters (temperature, salinity and pH) of the surrounding water and the bacteriological contamination levels found in the tested oysters. The only correlation found was between TC and FC...

The stormwater drain system as a pollution vector of the seashore in Fortaleza (Ceará State, Brazil)
Provedor de dados: 58
Autores: Vieira,Regine H.S.F.; Catter,Karla M.; Saker-Sampaio,Silvana; Rodrigues,Dália P.; Theophilo,Grace N.D.; Fonteles-Filho,Antonio A.
The aim of this study was to make a diagnosis of coastal pollution through bacteriological analysis of water taken from stormwater drain systems and the nearby seashore. The results were submitted to statistical analysis as to differences in the Most Probable Number (MPN) of fecal coliform (FC) found between the stormwater drain systems and adjacent seashore locations both at low and high tides. The main conclusions were: (a) most water samples collected from the stormwater systems presented MPN values for FC above 1,000 per 100 ml; (b) only 20% of the samples from the adjacent seashore presented MPN values for FC above 1,000 per 100 ml, a fact which may be explained by the distance between the drain system outlets and the actual seashore; (c) FC/100 ml...
