  • Anatomie 93 questions
  • Organismes 38 questions Any living biological entity, such as an animal, plant, fungus, or bacterium.
    • Eukaryota 3 questions
    • Archéobactéries 0 questions One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.
      • Pathogènes Transmissibles Par Le Sang 0 questions Organismes infectieux présents dans le sang, dont l'intérêt médical essentiel est la contamination des objets souillés : draps, serviettes, vêtements, compresses, bandes, aiguilles, scalpels et autres objets pointus d'usage médical ou dentaire auxquels les professionnels (sains) sont exposés. Ce concept est complètement différent des concepts cliniques de BACTEREMIE, VIR
      • Crenarchaeota 0 questions A kingdom in the domain ARCHAEA comprised of thermoacidophilic, sulfur-dependent organisms. The two orders are SULFOLOBALES and THERMOPROTEALES.
        • Desulfurococcales 0 questions An order of CRENARCHAEOTA comprised of irregular coccoid to disc-shaped, hyperthermophiles, and found in submarine hydrothermal systems and solfataric hot springs.
        • Sulfolobale 0 questions An order of CRENARCHAEOTA consisting of aerobic or facultatively aerobic, chemolithotrophic cocci which are extreme thermoacidophiles. They lack peptidoglycan in their cell walls.
          • Sulfolobaceae 0 questions A family of SULFOLOBALES consisting of aerobic or facultatively anaerobic chemolithotrophic cocci, usually occurring singly. They grow best at a pH of about 2.
        • Thermoproteales 0 questions An order of CRENARCHAEOTA comprised of rod, disc, or spherical shaped, nonseptate, anaerobic, extreme thermophiles and found in solfataric hot waters, mud holes, and superheated submarine environments.
      • Euryarchaeota 0 questions A phylum of ARCHAEA comprising at least seven classes: Methanobacteria, Methanococci, Halobacteria (extreme halophiles), Archaeoglobi (sulfate-reducing species), Methanopyri, and the thermophiles: Thermoplasmata, and Thermococci.
      • Korarchaeota 0 questions A kingdom in the domain ARCHAEA, comprising thermophilic organisms from the hot spring Obsidian Pool (Yellowstone National Park) that are among the most primitive of all life forms. They have undergone comparatively little evolutionary change since the last common ancestor of all extant life. (From ASM News, 1996; 62(9):468-9)
      • Nanoarchaeota 0 questions A kingdom of hyperthermophilic ARCHAEA found in diverse environments.
    • Bactéries 14 questions Bactéries, gram-positif, formant des endospores. Elles comprennent les genres suivants : BACILLUS ; CLOSTRIDIUM ; MICROMONOSPORA ; SACCHAROPOLYSPORA et STREPTOMYCES.
