| characterization of the most frequently encountered staphylococcus sp. in cats. | ninety three staphylococci isolated from clinical specimens from cats were characterized and identified. because the biochemical characteristics of staphylococcus felis were very similar to those of staphylococcus simulans, results were submitted to numerical analysis and dna homology. forty-two isolates (45%) were identified as s. felis, and 4 isolates (4%) as s. simulans. the other species identified, in order of their frequency were, 12 staphylococcus aureus (13%), 9 staphylococcus intermediu ... | 1994 | 8042273 |
| characterization of staphylococcus spp. and micrococcus spp. isolated from iberian ham throughout the ripening process. | the iberian dry cured ham is an uncooked meat product highly appreciated because of its characteristic flavour. this product is obtained from highly marbled iberian pig hindlegs after 18-24 months of maturation under natural environmental conditions. the role of micrococcaceae in the development of the aroma characteristics of this products remains unclear. identification of gram-positive, catalase-positive cocci isolated from mannitol salt agar plates showed that staphylococcus xylosus followed ... | 1994 | 7703026 |
| identification and ribotyping of staphylococcus xylosus and staphylococcus equorum strains isolated from goat milk and cheese. | twenty-five strains of staphylococci isolated from goat milk and cheese were identified as belonging to the staphylococcus xylosus/equorum group using the id 32 staph system (biomérieux, marcy-l'etoile, france). this system, however, was not able to discriminate between these two species for 19 of the strains tested. ribotyping was performed on these 25 strains, as well as on three reference strains of each of these two species. hybridization membranes were scanned and analyzed using the taxotro ... | 1996 | 8880319 |
| tandem duplication in ermc translational attenuator of the macrolide-lincosamide-streptogramin b resistance plasmid pses6 from staphylococcus equorum. | a tandem duplication of 23 bp in the ermc gene translational attenuator of plasmid pses6 from staphylococcus equorum which mediated constitutive resistance to macrolide-lincosamide-streptogramin b antibiotics was identified. this duplication included the ribosome binding site for the ermc gene as well as the first 5 bp of the ermc coding sequence. it was postulated that this sequence duplication affects the possible rna conformations so that the ribosome binding site for ermc synthesis is readil ... | 1996 | 8787908 |
| identification of staphylococcus species by 16s-23s rdna intergenic spacer pcr analysis. | to investigate whether 16s-23s rdna (rdna) spacer region length polymorphisms are suitable for the identification of staphylococcus strains, the 16s-23s rdna intergenic spacer region lengths of 221 strains belonging to 31 species were studied by using a pcr-based method. each species presented a specific 16s-23s pattern made of 1-8 fragments ranging from 104-771 bp, with the exception of the species staphylococcus warnei, staphylococcus caprae and staphylococcus piscifermentans, which presented ... | 1998 | 9734063 |
| staphylococcus succinus sp. nov., isolated from dominican amber. | two bacterial isolates, designated amg-d1t and amg-d2, were recovered from 25-35-million-year-old dominican amber. amg-d1t and amg-d2 biochemically most closely resemble staphylococcus xylosus; they differ physiologically from other staphylococci. fatty acid analysis and comparisons with extensive databases were unable to show relatedness to any specific taxon. moreover, amg-d1t and amg-d2 contain tuberculostearic acid and meso-diaminopimelic acid, characteristic of the g + c-rich coryneform bac ... | 1998 | 9731292 |
| the macrocyclic peptide antibiotic micrococcin p(1) is secreted by the food-borne bacterium staphylococcus equorum ws 2733 and inhibits listeria monocytogenes on soft cheese. | staphylococcus equorum ws 2733 was found to produce a substance exhibiting a bacteriostatic effect on a variety of gram-positive bacteria. the metabolite was purified to homogeneity by ammonium sulfate precipitation and semipreparative reversed-phase high-performance liquid chromatography. electrospray mass spectrometry confirmed the high purity of the compound and revealed a molecular mass of 1,143 da. by two-dimensional nuclear magnetic resonance spectroscopy the substance was identified as mi ... | 2000 | 10831414 |
| l-methionine degradation potentialities of cheese-ripening microorganisms. | volatile sulphur compounds are major flavouring compounds in many traditional fermented foods including cheeses. these compounds are products of the catabolism of l-methionine by cheese-ripening microorganisms. the diversity of l-methionine degradation by such microorganisms, however, remains to be characterized. the objective of this work was to compare the capacities to produce volatile sulphur compounds by five yeasts, geotrichum candidum, yarrowia lipolytica, kluyveromyces lactis, debaryomyc ... | 2001 | 11928962 |
| pyridinyl polythiazole class peptide antibiotic micrococcin p1, secreted by foodborne staphylococcus equorum ws2733, is biosynthesized nonribosomally. | recently, foodborne staphylococcus equorum ws2733 was isolated from a french red smear cheese on account of its strong inhibitory activity against gram-positive pathogens such as listeria. the antagonistic substance was identified as macrocyclic peptide antibiotic micrococcin p1, which had previously not been reported for the genus staphylococcus. micrococcin p1, also a potent inhibitor of the malaria parasite plasmodium falciparum, is structurally related to thiostrepton, thiocillins and nosihe ... | 2001 | 11737193 |
| molecular techniques open up new vistas for typing of coagulase-negative staphylococci. | several methods were used to type 64 clinical isolates of coagulase-negative staphylococci (cns) derived from hospitals in morocco. the clinical isolates originated principally from blood cultures and wound sources. these isolates provided the opportunity to substantially compare the proficiency of developing molecular techniques with conventional phenotypic tests for use in the identification of clinical staphylococci. the following molecular methods were examined: utility ribotyping analysis ( ... | 2001 | 11367554 |
| peptidolytic, esterolytic and amino acid catabolic activities of selected bacterial strains from the surface of smear cheese. | enzymes produced by bacteria present on the surface of smear cheeses play essential roles in flavour development during cheese ripening. in this study, strains including brevibacteria, corynebacteria, staphylococci and brachybacteria, from the surface of two smear cheese (tilsit and gubeen) were screened for a range of enzyme activities including aminopeptidase (substrates: leu-pna and his-pna), dipeptidase (met-ala, ala-met, pro-ala, his-leu and pro-leu), tripeptidase (phe-gly-gly, gly-gly-gly ... | 2002 | 12051480 |
| bacterial community structure and location in stilton cheese. | the microbial diversity occurring in stilton cheese was evaluated by 16s ribosomal dna analysis with pcr-denaturing gradient gel electrophoresis. dna templates for pcr experiments were directly extracted from the cheese as well as bulk cells harvested from a variety of viable-count media. the variable v3 and v4-v5 regions of the 16s genes were analyzed. closest relatives of lactococcus lactis, enterococcus faecalis, lactobacillus plantarum, lactobacillus curvatus, leuconostoc mesenteroides, stap ... | 2003 | 12788761 |
| staphylococcus equorum subsp. linens, subsp. nov., a starter culture component for surface ripened semi-hard cheeses. | two staphylococcal strains, rp29t and rp33, were isolated from the main microflora of a surface ripened swiss mountain cheese made from raw milk. these two strains were differentiated from the most closely related species staphylococcus equorum on the basis of dna-dna hybridisation and phenotypic characteristics and are proposed as staphylococcus equorum subsp. linens subsp. nov. they could be distinguished phenotypically from s. equorum by their sensitivity to all 14 tested antibiotics, especia ... | 2003 | 12747407 |
