In the genus Schizosaccharomyces intracellular osidases and nitrite and nitrate reductases are revealed; particularly all the species possessing invertase, alpha-glucosidase and alpha-galactosidase. These characters underline the homogeneity on the genus. On the basis of osidases, nitrite and nitrate reductases results, 2 groups can be distinguished in this genus.

The effect of exposure of Channa punctatus to a sub-lethal concentration of lead nitrate on the activities of alkaline phosphatase, acid phosphatase amylase, maltase, lactase, trypsin and pepsin has been investigated. A decrease in the activity of alkaline phosphatase has been recorded after 15 days of exposure but there was no significant change after 30 days. Acid phosphatase showed an elevation in activity of both stages. All the three carbohydrases shows elevation after 15 days, followed by an inhibition after 30 days of treatment. The activity of pepsin and trypsin remained above the normal level throughout the tensure of the experiment reveal that the pattern of alteration in enzyme activities is different in liver and digestive system.

Sixteen isolates from the vaginal discharge of women with bacterial vaginosis (non-specific vaginitis) and six provided by other investigators were divided into two groups on the basis of morphology and biochemical tests. Only one organism type was isolated from any one patient. The two groups differed in size, number of flagella, enzyme production, ability to ferment carbohydrates, hydrolyse hippurate and arginine, reduce nitrate, and produce ONPG, and in sensitivity to metronidazole. Both groups fermented glucose and maltose, produced succinate from glucose and alpha-glucosidase and leucine arylamidase.

The anti-diabetic drug miglitol, an alpha-glucosidase inhibitor, which is currently used clinically, reduces myocardial infarct size by reducing the glycogenolytic rate through inhibition of the alpha-1,6-glucosidase of glycogen-debranching enzyme in the heart. Nicorandil, a K(ATP) channel opener with a nitrate-like effect, which is also currently used clinically, also reduces the infarct size. Therefore, we hypothesized that combination of nicorandil and submaximal dose of miglitol could markedly reduce myocardial infarct size more than miglitol or nicorandil alone, and investigated the mechanism for the infarct size-reducing effect. Japanese white rabbits without collateral circulation were subjected to 30 min coronary occlusion followed by 48 h reperfusion. Pre-ischaemic treatment with submaximal dose of miglitol (5 mg kg(-1), i.v.) and nicorandil alone (100 microg kg(-1) min(-1) 5 min) moderately reduced the infarct size as a percentage of area at risk (24+/-4 and 25+/-4%, respectively), and 10 mg kg(-1) of miglitol markedly reduced the infarct size (15+/-2%) compared with the controls (42+/-2%). Combination of 5 mg kg(-1) of miglitol and nicorandil (100 microg kg(-1) min(-1) 5 min), and 10 mg kg(-1) of miglitol and nicorandil (100 microg kg(-1) min(-1) 5 min) significantly reduced the infarct size (13+/-4 and 12+/-3%, respectively) more than miglitol or nicorandil alone. Pretreatment with 5HD completely abolished the infarct size-reducing effect of 10 mg kg(-1) of miglitol alone (36+/-7%) and that of combination of 5 mg kg(-1) of miglitol and nicorandil (46+/-2%). Combination of nicorandil and submaximal dose of miglitol markedly reduced the myocardial infarct size more than miglitol or nicorandil alone. This effect was suggested to be related to the opening of mitochondrial K(ATP) channels.

A Gram-positive, short diphtheroid-shaped organism was isolated from a sow's placenta of an abortion. This novel isolate, strain Murakami(T), was examined physiologically, chemotaxonomically and phylogenetically. Cells had an irregular V-shaped or palisade arrangement. Colonies appeared translucent on TMVL agar. Cells were strictly anaerobic, negative for catalase and gelatin decomposition and positive for nitrate reduction and soluble starch hydrolysis. Fourteen sugars including glucose were utilized as carbon sources for growth, but 15 sugars including arabinose were not. alpha-Galactosidase, beta-galactosidase, alpha-glucosidase and leucine arylamidase were produced, but beta-glucosidase was not. Fermentation products were lactic, succinic and acetic acids. Sugars of whole cells consisted of rhamnose and ribose. The amino-acid composition of the peptidoglycan was glutamic acid, alanine and lysine in the molar ratio of 1 : 2 : 1. The main fatty acid components of whole cells were C(14 : 0), C(16 : 0), C(16 : 1)omega7 and C(18 : 1)omega9. The bacterial menaquinone was MK-10(H(4)). The polar lipids were phosphatidylethanolamine and two unknown phosphatidylinositol mannosides. The G+C content of the genomic DNA of strain Murakami(T) was 63.8 mol%. Phylogenetic analysis of 16S rRNA gene sequences from strain Murakami(T) and other members of the genus Arcanobacterium supported the phenotypic findings that strain Murakami(T) represents a novel species, for which the name Arcanobacterium abortisuis sp. nov. is proposed. The type strain is Murakami(T) (=ATCC BAA-1522(T) =DSM 19515(T) =JCM 14813(T)).

Two luminous marine bacterial strains, LC2-005(T) and LC2-102, were isolated from seawater at Kuroshio Region and Sagami Bay in Japan, respectively. These bacteria were Gram-negative, oxidase-positive, catalase-positive, motile and rod-shaped. On the basis of 16S rRNA gene sequence analysis, strains LC2-005(T) and LC2-102 formed a cluster within the Vibrio harveyi species group. However, multilocus sequence analysis using five loci (pyrH, ftsZ, mreB, gyrB and gapA) and DNA-DNA hybridization experiments indicated that these strains were distinct from the currently known Vibrio species. Additionally, these strains differ from related Vibrio species in utilization of glucose, mannitol, inositol, sorbitol, rhamnose, sucrose, melibiose and arabinose, production of lysine decarboxylase, ornithine decarboxylase, tryptophan deaminase, esterase (C4), lipase (C4), chymotrypsin, acid phosphatase, alpha-glucosidase, beta-glucosidase and N-acetyl-beta-glucosaminidase and the ability to reduce nitrate to nitrite. The major fatty acids were C(15 : 0) iso 2-OH and/or C(16 : 1)omega7c, C(16 : 0), C(18 : 1)omega7c and C(14 : 0). The DNA G+C contents of strains LC2-005(T) and LC2-102 were 45.2 and 45.5 mol%, respectively. On the basis of the polyphasic taxonomic evidence presented in this study, it can be concluded that strains LC2-005(T) and LC2-102 belong to the same genospecies and represent a novel species of the genus Vibrio, for which the name Vibrio azureus sp. nov. is proposed. The type strain is LC2-005(T) (=NBRC 104587(T) =KCTC 22352(T)).

Gram-positive, non-spore-forming rods were isolated from a human osteo-articular sample (strain 7400942(T)). Based on cellular morphology and the results of biochemical analysis, this strain was tentatively identified as a novel species of the genus Actinomyces. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the bacterium was closely related to the type strain of Actinomyces denticolens (96.9 % 16S rRNA gene sequence similarity). A comparison of biochemical traits showed that strain 7400942(T) was distinct from A. denticolens in a number of characteristics, i.e. in contrast with A. denticolens, strain 7400942(T) was negative for nitrate reduction and for beta-galactosidase, alpha-glucosidase and alanine arylamidase activities, it was positive for acid production from N-acetylglucosamine, melezitose and glycogen, and it was negative for acid production from turanose. Matrix-assisted laser-desorption/ionization time-of-flight MS protein analysis confirmed that strain 7400942(T) represents a novel species, as scores obtained for its spectra were significant (>2.2) only with strain 7400942(T). On the basis of phenotypic data and phylogenetic inference, it is proposed that this strain should be designated Actinomyces timonensis sp. nov.; the type strain is strain 7400942(T) (=CSUR P35(T)=CCUG 55928(T)).
