    Description: Amoebae potentially able to cause severe eye infections were isolated from 31 of 56 eyewash stations. Eyewash stations that contained a reservoir presented a greater hazard than those without a reservoir. The need to flush eyewash stations regularly as part of safe laboratory practices is emphasized.

    Titre: Marine Amoebae from Surface Waters of Chincoteague Bay, Virginia: Two New Genera and Nine New Species within the Families Mayorellidae, Flabellulidae and Stereomyxidae
    Auteur: Sawyer, Thomas K.
    Sujet: Biology;
    Description: Field trips to Chincoteague Bay, Virginia were made to determine the types of marine amoebae that could be detected in sea-water samples taken during different months of the year (January, April, May, August, October). Sea water from the bay ranged in salinity from 25.7 to 32.6 ‰, and temperature ranged from 4.5 to 28 C. Water samples collected in January (4.5 C) yielded approximately the same species diversity as water samples collected in August (28 C). Descriptions are offered of two new genera, Boveella n. g. (Mayorellidae) and Stygamoeba n. g. (Stereomyxidae), and nine new species: Mayorella corlissi, M. smalli, Vexillifera pagei, V. ottoi, V. browni, Triaenamoeba jachowskii, Flabellula hoguae, Boveella obscura, and Stygamoeba polymorpha.

    Titre: Isolation and Identification of Free-Living Marine Amoebae from Upper Chesapeake Bay, Maryland
    Auteur: Sawyer, Thomas K.
    Sujet: Biology;
    Description: Free-living amoebae were collected from low salinity sea water (16‰, or less) sampled during spring, fall, and winter. Water samples from the Tred Avon River, upper Chesapeake Bay, Maryland, had eight genera of marine amoebae, i.e., Mayorella, Vexillifera, Hyalodiscus, Vannella, Thecamoeba, Cochliopodium, Rugipes, and Trichamoeba. Other small limax amoebae, possibly belonging to the genus Hartmannella or Vahlkampfia, were not identified. The isolation and identification of aquatic amoebae from low salinity sea water showed that specific diagnostic features of some marine amoebae are preserved in both estuarine and oceanic sea-water habitats. The cultivation of amoebae from Chesapeake Bay sea water provided essential background information for recognizing and identifying free-living amoebae which could contaminate cultures of tissue or body fluid from diseased marine shellfish, or occur as facultative parasites in marine hosts.

    A New Strain of Paratetramitus jugosus from Laguna Figueroa, Baja California, Mexico

    Titre: A New Strain of Paratetramitus jugosus from Laguna Figueroa, Baja California, Mexico
    Auteur: Read, Laurie K.; Margulis, Lynn; Stolz, John; Obar, Robert; Sawyer, Thomas K.
    Sujet: Medicine ; Biology;
    Description: A euryhalic, moderately temperature tolerant, fast growing strain of the amoebomastigote Paratetramitus jugosus was isolated from the North Pond flat laminated microbial mat at Laguna Figueroa, Baja California del Norte, Mexico. The morphology was studied with phase contrast, differential interference contrast, scanning, and transmission electron microscopy. On the basis of its life cycle characteristics, growth rate, salt and heat tolerance, fluorescence excitation and emission spectra, and isozymes, the organism was determined to be a new strain, P. jugosus baja californiensis. This new strain, unlike the type specimen (ATCC 30703), grows vigorously on half strength sea water and slowly at 0.51 M (nearly 3 per cent) sodium chloride. It tolerates the hypersaline conditions of the evaporite flat that prevail when the North Pond mats are dominated by Microcoleus and other bacteria, growing well during periods of influx of fresh water. Its cysts survive complete dryness of the sediment for at least three years. The microbial mats in which this Paratetramitus jugosus has been found are thought to have Archean analogues over 3 billion years old. The discovery of resistant abundant small eukaryotes within a setting dominated by bacteria may be important for the interpretation of the Proterozoic microbial fossil record.
