Numerical taxonomy of catalase-negative cocci isolated from frozen vegetables.
Taxonomic data for 135 cultures of bacteria isolated from frozen snap beans and whole kernel corn were analyzed by computer. Of the isolates, 79% were grouped into five major clusters. Two of the groups consisted of leuconostocs, whereas the other three contained homofermentative types. The intergroup similarities suggested a generic level of similarity. Feature frequencies for the groups were ...
متن کاملIdentification of catalase-negative, non-beta-hemolytic, gram-positive cocci isolated from milk samples.
This study was undertaken in an effort to improve the identification scheme of catalase-negative, non-beta-hemolytic, gram-positive cocci isolated from milk samples obtained from cows. First, the sensitivity and specificity of the identification procedure currently in use in our laboratory were compared to the results obtained with API 20 STREP strips which were set as the gold standard. Second...
متن کاملAntibiotic Resistance and Biofilm Production in Catalase-Positive Gram-Positive Cocci Isolated from Brazilian Pasteurized Milk
Background: Milk is a reservoir for several groups of microorganisms, which may pose health risks. The aim of this work was to assess the antibiotic resistance and biofilm production in catalase-positive Gram-positive cocci isolated from Brazilian pasteurized milk. Methods: The bacteria were isolated using Baird-Parker agar and identified by Matrix-Assisted Laser Desorption/Ionization-Time-Of-...
متن کاملCharacterization of atypical aerobic gram-negative cocci isolated from humans.
Six atypical aerobic gram-negative cocci, isolated from humans, were classified taxonomically by genetic relatedness (DNA base pairs and DNA homology), fatty acid content, pigment absorption profile, and other physiological and biochemical characteristics. One strain (M448), which produced acid only from glucose, was identified as Neisseria meningitidis; one strain (CH), which produced acid fro...
متن کاملcatalase-negative staphylococcus aureus isolated from a diabetic foot ulcer
we report a catalase-negative staphylococcus aureus isolated from a 56-year-old male diabetic patient with foot ulcer who attended our surgery ward. species identification was confirmed by gram staining, standard biochemical tests and pcr amplification of the nuc and fem genes. antibiotic susceptibility showed that the strain was sensitive to imepenem, chloramphenicol, amoxicillin, vancomycin a...
