Unification of the Genera Serpulina and Brachyspira, and Proposals of Brachyspira hyodysenteriae Comb. Nov., Brachyspira innocens Comb. Nov. and Brachyspira pilosicoli Comb. Nov.
TLDR
It is proposed to transfer the three species of the genus Serpulina to the genus Brachyspira, because their 16S ribosomal DNA sequences were related more than 96.0%.
Presence of 22-kDa protein reacting with sera in piglets experimentally infected with Brachyspira hyodysenteriae.
TLDR
The results showed that the SP-treated piglets did not display clinical signs of swine dysentery unlike the untreated piglets, which indicates that the 22- and 17-kDa proteins are common to eight strains of B. hyodysenteriae which differ serologically from each other.
Complete nucleotide sequence of the cytochrome b gene of channel catfish Ictalurus punctatus and comparison of sequence homology among channel catfish and other fishes.
TLDR
To clarify the phylogenic relationship of channel catfish with other fishes, the cytochrome b (Cyt b) gene of the catfish was cloned and sequenced and suggested that the Cyt b gene was closely related to that of a goldfish in the order Cypriniformes.
Studies on the structure of a novel peptide antibiotic, K-582.
A novel peptide antibiotic, K-582, which exhibited significant growth inhibition of Candida, viruses and ascites tumor in mice, was found in the culture medium of a strain of Metarhizium anisopliae
A Novel Lepidopteran Sex Pheromone Produced by Females of a Lithosiinae Species, Lyclene dharma dharma, in the Family of Arctiidae
TLDR
Female moths of Lyclene dharma dharma produced three pheromone components (I–III), which strongly stimulated male antennae, indicating that these methyl-branched ketones constitute a new chemical group of lepidopteran female sex phersomones.
Positions and Stereochemistry of Methyl Branches in the Novel Sex Pheromone Components Produced by a Lichen Moth, Lyclene dharma dharma
TLDR
The GC-MS analyses revealed that natural components I and II were best fitted with those of 1 and 2, respectively, among the methyl-2-octadecanones examined, indicating the usefulness of this analytical instrument and authentic standards for the determination of the positions of methyl branches.
Synthesis and Field Evaluation of Methyl-branched Ketones, Sex Pheromone Components Produced by Lithosiinae Female Moths in the Family of Arctiidae
TLDR
Female moths of Lyclene dharma dharma produce a novel sex pheromone composed of three methyl-branched ketones, and effective male attraction was observed for the 2:1:1 mixture of I–III, indicating that the females do not produce only one stereoisomer for each component or that the response of the males is not disturbed by the other stereoisomers of natural isomers produced by the females.
