    Notes: Abstract. A disease of cultured juvenile European oyster, Ostrea edulis, and American oysters, Crassostrea virginica, was characterized by infection of conchiolinous ligament and periostracum by surface-coating Vibrio spp. bacteria. A similar bacterium was isolated from diseased cultured hard clams, Mercenaria mercenaria, held in a facility about 300 km distance from the oyster hatcheries. The oysters demonstrated fragile, undercalcified peripheral shell and apparently excessive chalky deposits. Histological and scanning electron microscopical examination revealed that the oysters' eroded ligaments and perforated peripheral periostracum were infected with uniform rod-shaped bacteria. The infection appeared to interfere with normal proteinaceous and calcareous shell deposition and possibly with normal ligament function. Histological examination of the digestive system organs suggested that normal digestive processes were also interrupted. Two predominant bacteria were isolated from oyster samples and one predominant bacterium was isolated from clam samples. One of the isolates from oyster culture facilities was found almost exclusively associated with oyster shell surfaces and culture tank surfaces, this isolate was similar to the one taken from clam shell surfaces. The other predominant bacterium was found in water column samples in oyster culture facilities at levels from about 105 to 107 per ml. This isolate had a DNA base ratio (moles % G + C) of 43.6; the two surface-associated isolates had base ratios of 43.6 and 44.5%. These Gram-negative, oxidase positive, fermentive rods have been identified as a Vibrio spp. group. Specific antibody was produced which differentiated these bacteria from each other and from other similar isolates. Practical procedures for controlling the bacteria in shellfish culture systems are described.

    Notes: Abstract Water, sediment and microorganisms were sampled at stations along a trackline in the Atlantic Ocean off the North Carolina Coast (USA) at depths of 9 to 5,000 m. Selected chemical and physical parameters were measured. At three of the stations, microorganisms isolated from sediment were examined for ability to degrade a number of petroleum hydrocarbons. Media made up with seawater or salts solution supplemented with nitrate and phosphate were employed in the degradation studies; significant growth and hydrocarbon degradation was observed. Bacteria from sediment samples collected at a depth of 5,000 m showed greater growth and hydrocarbon degradation when cultured in a sea-water medium than in media made up with salts solution. Growth of bacteria in sediment samples collected at two stations was found to be suppressed in sea-water medium when a 1% (v/v) mixture of 19 different petroleum hydrocarbons was added. The hydrocarbon mixture was useful in determining the hydrocarbon degrading potential of microorganisms isolated from the ocean environment.

    Notes: Abstract Studies of the seasonal distribution of heterotrophic bacteria in Chesapeake Bay (USA) led us to the observation that fungizone was selective for actinomycetes without appreciably altering the total viable aerobic, heterotrophic bacterial counts. A study of the actinomycete populations in the Bay was undertaken, with several media compared for ability to enrich for actinomycetes: basal, casein, Czapek, starch-casein, glycerol-glycine, chitin and oil agar No. 2. Between 40 and 100% of the colonies appearing on chitin and oil No. 2 media were found to be actinomycetes, compared with 〈2% for the other media employed. It was also found that if sediment samples are frozen, a practice followed when laboratory facilities are not available in the field, a decrease in the total counts and in the actinomycete colony counts occurred. However, on a proportional basis, a slight increase in the percent actinomycetes was noted. A minimum of 21 days incubation time is recommended for recovery of actinomycetes. Also, the absence of NaCl from the actinomycete isolation media and incubation temperatures ≥15°C should give good recoveries of actinomycetes. A seasonal distribution of actinomycetes was noted for Chesapeake Bay, with maximal populations of actinomycetes observed in March and November. Actinomycetes were isolated in the ocean from depths ranging from 7 to 7,790 m. Greater numbers of actinomycetes were isolated using an incubation temperature of 25°C for the estuarine stations and 15°C for the deep-ocean stations. Greater numbers of actinomycetes were associated with polluted environments close to shore.

    Notes: Summary Single-strand-specific nuclease S1 was employed as a structural probe to confirm locations of unpaired nucleotide bases in 5S rRNAs purified from prokaryotic species of rRNA superfamily I. Limited nuclease S1 digests of 3′- and 5′-end-labeled [32P]5S rRNAs were electrophoresed in parallel with reference endoribonuclease digests on thin allel with reference endoribonuclease digests on thin sequencing gels. Nuclease S1 primary hydrolysis patterns were comparable for 5S rRNAs prepared from all 11 species examined in this study. The locations of base-paired regions determined by enzymatic analysis corroborate the general features of the proposed universal five-helix model for prokaryotic 5S rRNA, although the results of this study suggest a significant difference between prokaryotic and eukaryotic 5S rRNAs in the evolution of helix IV. Furthermore, the extent of base-pairing predicted by helix IV needs to be reevaluated for eubacterial species. Clipping patterns in helices II and IV appear to be consistent with a secondary structural model that undergoes a conformational rearrangement between two (or more) structures. Primary clipping patterns in the helix II region, obtained by S1 analysis, may provide useful information concerning the tertiary structure of the 5S rRNA molecule.

    Notes: Abstract Veliger larvae of the oysterCrassostrea gigas (Thunberg) responded to unknown dissolved chemical inducers found in supernatants of cultures of the bacteriaAlteromonas colwelliana andVibrio cholerae. The response, which was similar to that seen when larvae were exposed to the neurotransmitter precursor L-3,4-dihydroxyphenylalanine (L-DOPA), consisted of an initial settlement phase of swimming with the foot extended and crawling on the substrate. Subsequently larvae attached to the substrate and metamorphosed. The percentage of veligers metamorphosing following inducation of settlement behavior was higher in a group of older larvae, a response similar to that seen with L-DOPA, suggesting that competence to respond to bacterial supernatants is divided into two phases: behavioral competence followed by morphogenetic competence. Following size exclusion chromatography, the molecular weight of the peak containing the activity which induced settlement behavior was determined to be ≤ 300 daltons. Autoclaved Marine Broth, which induced low levels of settlement behavior also contained this low molecular weight active peak, suggesting that an oyster settlement inducer is also present in this medium.
