Staphylococcus aureus causes various pus-forming infections such as boils‚ styes‚ pneumonia‚ urinary tract infections‚ and more seriously osteomyelitis and endocarditis (Todar‚ PhD‚ 2008). The recurring theme of Sir Fleming’s career was to find a chemical substance

The food produced is processed using chemicals which in turn make people less immune and vulnerable to developing disease. Reports indicate that there are a significant number of people in the society suffering from various diseases (Shorter and David 155). Therefore‚ scientists worked to make antibiotics

I believe cell phones are dangerous to our health because they have been linked to causing tumors‚ can affect your eye health‚ and they also hold a lot of bacteria. Cell phones have more serious risks than they do benefits. Therefore it is better to limit how much you use your cell phone. It has been scientifically proven that

Next‚ the Nitrate test was used to differentiate between the two remaining possibilities. Since the unknown Gram-positive bacterium resulted in a negative for Nitrate‚ the organism was identified as Staphylococcus simulans. As for the identification of the unknown Gram-negative bacterium‚ the unknown bacterium’s

There are many hospital departments‚ staffed by a wide variety of healthcare professionals‚ with some crossover between departments. For example‚ physiotherapists often work in different departments and doctors often do the same‚ working on a general medical ward as well as an intensive or coronary care unit. Each department tends to be overseen by consultants in that specialty with a team of junior medical staff under them who are also interested in that specialty. Accident and emergency this department

It was most likely the result of: a. Staphylococcus aureus. The chickens got in contact with human who carries disease‚ in this case most probably from the chef b. Clostridium perfringens.

Nafcillin and cefazolin are considered first-line therapy for most infections with methicillin-susceptible Staphylococcus aureus (MSSA).1 Nafcillin is a Beta-lactam antibiotic which is mainly bactericidal‚ anti-staphylococcal. Due to its side chains‚ it is penicillinase hydrolysis resistant. Thus‚ its coverage for MSSA. It Is usually unlikely to experience Drug-induced
