Maintenance of equilibrium between free radical production and antioxidant defences (enzymatic and non enzymatic) is an essential condition for normal organism functioning. When this equilibrium has a tendency for the production of free radicals we say that the organism is in oxidative stress. In this situation, excess free radicals may damage cellular lipids, proteins and DNA, affecting normal...

The dominant aerobic microorganism in cattle feedlot waste (FLW) is a corynebacterium. It is ubiquitous to FLW except on sites where antibiotics are a constant part of the animals' diet. The organism requires DL-aspartic acid as its nitrogen source for growth, and individual strains also require or are stimulated by L-tyrosine; acetate serves as the carbon source. Amylolytic activity is weak; p...

The study was designed to determine the bacterial quality of local fried ground beef (Dambun nama) sold and consumed in Sokoto metropolis. Between January and December 2009, 216 samples of fried ground beef were collected and processed for bacterial isolations. Plate count agar, Violet Red bile lactose agar, RAPID E. coli agar and tellurite emulsion plates were used for the isolation of aerobic...

Metabolic rate is a key ecological variable that quantifies the energy expenditure needed to fuel almost all biological processes in an organism. rates are typically measured at whole-organism level (woMR) with protocols can elicit stress responses due handling and confinement, potentially biasing resulting data. Improved, non-stressful methodology would be especially valuable for measures of f...

Cupriavidus gilardii was first identified as an aerobic, gram-negative, glucose-nonfermenting rod. C. gilardii has been characterized as an organism with low pathogenicity that causes opportunistic infections and few case reports of infection caused by this organism previously. We encountered the first case of bloodstream infection caused in China by C. gilardii in a 87-year old man without obv...

Oxygen metabolism is a strong predictor of the general health and fitness of an organism. In this study, we hypothesized that a divergence in intrinsic aerobic fitness would co-segregate with susceptibility for cardiovascular dysfunction. To test this hypothesis, cardiac function was assessed in rats specifically selected over nineteen generations for their low (LCR) and high (HCR) intrinsic ae...

During a one-year period, a total of 6,305 blood cultures were processed in a tertiary-care teaching hospital; 6 to 12 ml of blood was inoculated into both a BacT/Alert Fan aerobic bottle and an ESP 80A aerobic bottle. The FAN aerobic bottle contains an antimicrobial-absorbing material; the 80A aerobic bottle does not. Bottles were processed on their respective continuous-monitoring blood cultu...

introduction campylobacter jejuni is a slender, motile, non-spore-forming, helical-shaped, gram-negative bacterium. it is one of the most common causes of human gastroenteritis in the world. the aim of this study was to present a patient with acute lymphocytic leukemia (all), who was infected with campylobacter jejuni. conclusions c. jejuni should be considered in the differential diagnosis as ...
