13. Bactérias de origem fecal contaminantes de ostra Crassostrea rhizophorae, oriundas do estuário do Rio Cocó, Estado do Ceará, Brasil
O objetivo deste trabalho foi avaliar a qualidade microbiológica da ostra de mangue (Crassostrea rhizophorae) originária de um criadouro natural no estuário do Rio Cocó, Fortaleza, Ceará, Brasil. Para isso, foram realizadas as estimativas do Número Mais Provável (NMP) de Coliformes Totais (CT) e de Fecais (CF) e de Enterococcus spp. Os valores encontr

14. Isolamento de Vibrio parahaemolyticus e Vibrio cholerae em ostras, Crassostrea rhizophorae, coletadas em um criadouro natural no estuário do rio Cocó, Fortaleza, Ceará, Brasil
As ostras são alimentos marinhos freqüentemente ingeridos crus ou parcialmente cozidos. Por esta razão, o risco para a saúde dos consumidores desses produtos é muito elevado, principalmente, quando são de regiões tropicais. Foi estudada a presença de Vibrio cholerae e Vibrio parahaemolyticus em ostras de um estuário na região Nordeste do Brasil. Tr

15. Detection of human calicivirus (Small round structured virus - SRSV) using polymerase chain reaction (PCR) in oysters from São Paulo beaches, Brazil. / Detecção de Calicivírus Humano (Small Round Structured Virus-SRSV) pela Relação em Cadeia da Polimerase( PCR) em Ostras do Litoral do Estado de São Paulo.
Vírus causadores de gastroenterite, descritos como pequenos vírus de estrutura arredondada (Small Round Structured Viruses-SRSV), foram detectados em extratos de ostras Crassostrea spp., coletadas em regiões distintas do litoral do Estado de São Paulo, utilizando a Reação em Cadeia por Polimerase com transcrição reversa (RT-PCR).Treze lotes de amostr

16. Evidence for colonization and destruction of hinge ligaments in cultured juvenile Pacific oysters (Crassostrea gigas) by cytophaga-like bacteria.
Several strains of cytophaga-like gliding bacteria (CLB) were isolated as numerically dominant or codominant components of bacterial populations associated with proteinaceous hinge ligaments of cultured juvenile Pacific oysters, Crassostrea gigas. These bacteria were morphologically similar to long, flexible bacilli occurring within degenerative lesions in o

17. Behavior of pathogenic bacteria in the oyster, Crassostrea commercialis, during depuration, re-laying, and storage.
Oysters (Crassostrea commercials) harvested from major cultivation areas within the state of New South Wales, Australia, were commonly contaminated with low levels of the food-poisoning organisms Bacillus cereus, Clostridium perfringens, and Vibrio parahaemolyticus. Salmonella was found in oysters on only one occasion. These bacteria were cleansed from oyste

18. Scanning Electron Microscopy of Cristispira Species in Chesapeake Bay Oysters
Scanning electron microscopy was employed to observe the physical interactions between Cristispira spp. and the crystalline style of the Chesapeake Bay oyster (Crassostrea virginica Gmelin 1791). Cristispira organisms were found associated with both the inner and outer layers of the posterior two-thirds of the style. The spirochetes possessed blunt-tipped en

19. Incidence of Vibrio parahaemolyticus Bacteriophages and Other Vibrio Bacteriophages in Marine Samples †
Vibrio bacteriophages were isolated by enrichment from 177 of 643 samples of marine molluscan shellfish, crustaceans, seawater, and sediments. The predominant bacteriophage types isolated were specific for some strains of Vibrio parahaemolyticus. A high frequency of phage isolations was also observed with strains of agar-digesting vibrios (21 of 56) and psyc

20. Real-Time PCR for Detection and Quantification of the Protistan Parasite Perkinsus marinus in Environmental Waters†
The protistan parasite Perkinsus marinus is a severe pathogen of the oyster Crassostrea virginica along the east coast of the United States. Very few data have been collected, however, on the abundance of the parasite in environmental waters, limiting our understanding of P. marinus transmission dynamics.
