Gram-positive, catalase-positive cocci (Micrococcaceae) have been obtained from the bladder by suprapubic aspiration of urine in antenatal and postnatal patients. These bacteria have been compared with similar organisms isolated from midstream specimens of urine when the suprapubic specimen was sterile. Fourteen (70%) of 20 organisms isolated from the bladder were micrococci and six (30%) were ...

Brevibacterium spp. are catalase-positive, non-spore-forming, non motile, aerobic Gram-positive rods that were considered apathogenic until a few reports of infections in immunocompromised patients had been published. To the best of our knowledge, this is the first report of B. casei catheter-related bloodstream infection in a child with acute leukemia. We aim to enhance the awareness of pediat...

The aim of this study was correlation determination between fat putrefaction indices and antioxidative enzymes in chicken, cattle and camel meat during refrigerated storage. Longissimus dorsi muscle of three Iranian dromedary one humped camel and three Holstein cattle and breast muscle of three broiler breeder chicken were obtained from the carcasses 3 days postmortem. The samples were ground a...

SYNOPSIS Strains of Gram-positive, catalase-positive, coagulase-negative cocci isolated from urine specimens were classified by the system of Baird-Parker (1963). Urinary infections attributed to instrumentation or pathological abnormalities of the urinary tract were caused almost entirely by various Staphylococcus subgroups. These showed a wide range of antibiotic sensitivities, unrelated to s...

The paper evaluates the contents of total forms of selected heavy metals (Zn, Cu, Ni and Pb) as well as the activity of catalase (CAT), dehydrogenases (DEH), alkaline phosphatase (AlP) and acid phosphatase (AcP) in mineral surface horizons of forest soils exposed to the effect of road traffic pollutions. The sampling locations (n = 24) were determined in the area covered by the Szubin Forest al...

Catalase is an iron porphyrin enzyme, which serves as an efficient scavenger of reactive oxygen species (ROS) to avoid oxidative damage. In sugarcane, the enzymatic activity of catalase in a variety (Yacheng05-179) resistant to the smut pathogen Sporisorium scitamineum was always higher than that of the susceptible variety (Liucheng03-182), suggesting that catalase activity may have a positive ...

Reactive oxygen species (ROS) are important in the initiation and promotion of cells to neoplastic growth. In this context, cigarette smoke exposure, the primary risk factor in lung cancer development, leads to high levels of ROS within the human airway. Although well-equipped with an integrated antioxidant defense system consisting of low-molecular weight antioxidants such as glutathione and i...
