Strains of Amycolatopsis orientalis produce vancomycin or other related glycopeptide antibiotic compounds. Here we report the draft genome sequences of glycopeptide nonproducers Amycolatopsis orientalis subsp. orientalis DSM 43388 and DSM 46075. Their genome information will provide insights into the acquisition and regulation of glycopeptide antibiotic resistance genes.

An Alkanna orientalis leaf and flower extract inhibited the growth of Staphylococcus aureus, a pathogen that causes an estimated 478 000 hospitalizations in the US annually. Bioassay-guided fractionation of A. orientalis resulted in isolation of the flavonoid sarothrin (5,7,4'-trihydroxy-3,6,8-trimethoxyflavone), which inhibited the growth of Mycobacterium smegmatis (MIC 75 µM) and S. aureus (M...

Amycolatopsis orientalis DSM 43387, a clinical isolate from submandibular mycetoma tissue, is one of three plasmid-bearing strains of the genus Amycolatopsis. It degrades aromatic compounds such as m-hydroxybenzoate, but does not produce any antibiotics, in contrast to Amycolatopsis orientalis NBRC 12806T. Phylogenetic analysis based on a complete 16S rRNA gene sequence placed the strain in the...

In this study, esterase isozyme polymorphisms in Boreal-Tertiary origin relict endemic L. orientalis populations were investigated. Four populations located in the Southern and the Southwestern regions of Turkey were screened. Two of these populations (Fethiye-Günlüklü and Fethiye-İnlice) belong to subspecies L. orientalis Mill.var. orientalis. The other two (Muğla-Köyceğiz and Antalya-Gebiz) b...

A bird-parasitic fly, Carnus orientalis Maa, 1968, is recorded for the first time from Japan, and it is taxonomically reexamined on the basis of specimens collected in Okinawa Prefecture. Adult flies were found from nestlings of Ryukyu scops owl (Otus elegans Cassin, 1852), which is a new host for C. orientalis. Bionomic remarks regarding C. orientalis are presented, and akey to the world speci...

Frogs have two inner ear organs, each tuned to a different range of frequencies. Female treefrogs (Hylidae) of three species in which males produce calls with a bimodal spectrum (Hyla chrysoscelis, H. versicolor, H. arenicolor) preferred alternatives with a bimodal spectrum to alternatives with a single high-frequency peak. By contrast, females of H. avivoca, in which males produce calls with a...

A total of 305 individuals from a hybrid population of North American tree frogs was characterized for allozyme and mitochondrial DNA (mtDNA) genotype. Species-specific mating behaviors had suggested the potential for directional hybridization, in which matings between Hyla cinerea males and Hyla gratiosa females numerically predominate over the reciprocal combination. Such directional bias lea...
