purification and properties of gentisate 1,2-dioxygenase from moraxella osloensis.gentisate:oxygen 1,2-oxidoreductase (decyclizing) (ec; gentisate 1,2-dioxygenase) from moraxella osloensis was purified to homogeneity as shown by polyacrylamide gel electrophoresis. the enzyme has a molecular weight of about 154,000 and gives rise to subunits of molecular weight 40,000 in the presence of sodium dodecyl sulfate. gentisate 1,2-dioxygenase showed broad substrate specificity and attacked a range of halogen- and alkyl-substituted gentisic acids. maleylpyruvate, the product ...1975234947
unusual effects of penicillin g and chloramphenicol on the growth of moraxella osloensis.growth of exponential-phase liquid cultures of moraxella osloensis was inhibited by 0.5 u of penicillin g per ml. for this organism, low concentrations of penicillin acted primarily in a bacteriostatic rather than in a bactericidal manner. at higher concentrations of penicillin some killing did take place, but the rate of killing was rather slow and appeared to be independent of penicillin concentration. microscopic observation of cells from penicillin-treated cultures showed little or no cellul ...1977335964

microbiome analysis and confocal microscopy of used kitchen sponges reveal massive colonization by acinetobacter, moraxella and chryseobacterium species.the built environment (be) and in particular kitchen environments harbor a remarkable microbial diversity, including pathogens. we analyzed the bacterial microbiome of used kitchen sponges by 454-pyrosequencing of 16s rrna genes and fluorescence in situ hybridization coupled with confocal laser scanning microscopy (fish-clsm). pyrosequencing showed a relative dominance of gammaproteobacteria within the sponge microbiota. five of the ten most abundant otus were closely related to risk group 2 (rg ...201728725026
fibrinous pericarditis secondary to bacterial infection in a cat.a three-year-old spayed domestic short-haired cat presented for evaluation of weight loss, cardiomegaly and pleural effusion. echocardiographic examination demonstrated a thickened pericardium with mild pericardial effusion and a large volume of pleural effusion characterized by exudate. although the cat was treated with antibiotics, the clinical symptoms did not improve. the cat developed dyspnea and died on day 7. necropsy revealed a large amount of modified transudates ascites, pleural effusi ...201728484098
