A complex of polypeptides derived from a precursor is present on the surface of the malaria merozoite. During erythrocyte invasion only a small fragment from this complex is retained on the parasite surface and carried into the newly infected red cell. Antibodies to this fragment will interrupt invasion.
The ancestor of Gloeobacter violaceus PCC 7421(T) is believed to have diverged from that of all known cyanobacteria before the evolution of thylakoid membranes and plant plastids. The long and largely independent evolutionary history of G. violaceus presents an organism retaining ancestral features of early oxygenic photoautotrophs, and in whom(More)
A Gram-negative bacterium, designated LA33B(T), was isolated from water collected from a hypersaline lake on uninhabited Laysan Atoll in the Northwestern Hawaiian Islands. Cells of strain LA33B(T) are motile, straight rods that grow between 4 and 45 degrees C and in media containing 1-17.5% (w/v) NaCl. The strain oxidizes carbohydrates, nucleosides, amino(More)
A Gram-negative bacterium, designated LA31B(T), was isolated from water collected from a hypersaline lagoon on Laysan Atoll in the north-western Hawaiian Islands. Single cells of LA31B(T) were slightly curved but became helical as their length increased. Preliminary characterization based on 16S rRNA gene sequence analysis showed that LA31B(T) shared 96.0 %(More)
We report the complete genome sequence of the deep-sea gamma-proteobacterium, Idiomarina loihiensis, isolated recently from a hydrothermal vent at 1,300-m depth on the Loihi submarine volcano, Hawaii. The I. loihiensis genome comprises a single chromosome of 2,839,318 base pairs, encoding 2,640 proteins, four rRNA operons, and 56 tRNA genes. A comparison of(More)
Strain IK-1(T) was isolated from decaying tissues of the shrub Wikstroemia oahuensis collected on O'ahu, Hawai'i. Cells were rods that stained Gram-negative. Gliding motility was not observed. The strain was oxidase-negative and catalase-positive. Zeaxanthin was the major carotenoid. Flexirubin-type pigments were not detected. The most abundant fatty acids(More)
We report a ribosomal tag pyrosequencing study of the phylogenetic diversity of Archaea, Bacteria and Eucarya over a depth profile at the Hawaii Ocean Time-Series Station, ALOHA. The V9 region of the SSU rRNA gene was amplified from samples representing the epi- (10 m), meso- (800 m) and bathy- (4400 m) pelagia. The primers used are expected to amplify(More)
The Hawaiian Archipelago is a "biodiversity hotspot" where significant endemism among eukaryotes has evolved through geographic isolation and local topography. To address the absence of corresponding region-wide data on Hawaii's microbiota, we compiled the first 16S SSU rDNA clone libraries and cultivated bacteria from five Hawaiian lakes, an anchialine(More)
A Gram-negative bacterium designated LA1(T) was isolated from water collected in hypersaline Lake Laysan on Laysan Island in the Northwestern Hawaiian Islands. Cells occurred singly as fine rods to short filaments. Growth in 50 % strength marine broth occurred optimally when the medium contained 7.5-10 % (w/v) NaCl. The major fatty acids in LA1(T) grown at(More)
