Abstract:
Three novel strains were isolated from a soil sample collected in Japan using GPM agar plates supplemented with superoxide dismutase and/or catalase. The strains were Gram-positive, catalase-positive, irregular rod-shaped bacteria with meso-diaminopimelic acid as a peptidoglycan diagnostic diamino acid, and the acyl type of the peptidoglycan was acetyl. The major menaquinone was MK-8(H4). Mycolic acids were not detected. The G+C content of the DNA was 72-73 mol%. On the basis of morphological and chemotaxonomic properties and a phylogenetic analysis using 16S rRNA gene sequences, these strains were classified as a novel genus and species, Oryzihumus leptocrescens gen. nov., sp. nov., in the family Intrasporangiaceae of the order Actinomycetales. The type strain is KV-628T (=NRRL B-24347T=JCM 12835T=NBRC 100762T).

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
