MICROBIOLOGY SECTION The microbiology section aims at studying yu ailments and diseases from the isolation of suspected causative organisms. The processes involved in the isolation of these organisms include; culturing‚ staining‚ microscopy and sensitivity tests. Samples collected for examination include; stool‚ blood‚ sputum‚ urine‚ vaginal swab‚ wound swab and wound biopsy. Bacterial Culturing and sensitivity Cultures are carried out to isolate suspected organisms from a sample. There are different

Exercise 5 Introduction: Many different species of bacteria look similar under the microscope and also have the same staining results (ex. Gram stain). To be able to differentiate between the different species‚ one can look at the metabolic differences (fermentation)‚ as well as the environmental condition differences (temperature‚ pH‚ oxygen requirements). Being able to manipulate these conditions in a controlled environment can help to correctly identify the exact bacteria. Different media

The number of methicillin-resistant Staphylococcus aureus identified by a blood lab was less than 1.2% for Baldwin Infirmary nationally however in Florida this illness was found 69% of the time.

it is used to describe a set of chemicals that inhibit or kill bacteria. In 1982‚ the British scientist Alexander Fleming is credited with being first to notice that another organism could inhibit growth. He noticed that growth of bacterium Staphylococcus aureus was inhibited by a mold (fungus) that contaminated his plate. The mold was later identified as Penicillin notatum and the antibiotic isolated a short time later was named penicillin. *bacteria that
