(Larkin et al. 1990; Gray et al. 1995) Gray et al found that bacterial contamination is common in 77% of lens cases‚ followed by contamination with fungi (24%) and then protozoan (20%). Most commonly found organisms include Pseudomonas aeruginosa‚ Staphylococcus spp‚ Acanthamoeba spp and Fusarium species from CL cases. But still there are variations in isolated organisms from contact lens storage case in different studies. Studies also have documented the most commonly recovered micro-organisms in contact

the skin. The two main micro-organisms that cause TSS are Staphylococcus aureus and Streptococcus pyogenes. TSS is associated with the use of highly absorbent tampons but can also arise from Staphylococcus aureus infection at non-genital areas (for example wounds).[4] "From a UK population of around 60 million there were about 40 cases reported each year‚ half of which are associated with women using tampons."

Some organisms were too large to measure. Antibiotics were susceptible to bacteria and had less growth‚ whereas antiseptics were resistant to bacteria‚ and had more growth. Antiseptic of S. epidermidis had more growth than antibiotic of S. epidermidis. Antiseptics of S. epidermidis were most effective and Mr. clean had more growth all over the agar. S. epidermis of antibiotic were the most effective because it was susceptible and Chloramphenicol and tetracycline had a little bit of

Staphylococcus Aureus is a common cause for infections in the community and a major cause in hospital based disease. Up to 40% of the general public thought to be carriers and of hospital staff from 50 – 70%‚ and is associated with a higher risk of infection in the hospital setting. The anterior nares have been shown to be the most frequent site of carriage and are the single site of detection. [1] In certain situations‚ hospital patients and staff may be investigated and screened to identify carriers

After waiting for 24-48 to observe growth‚ I recorded my observations. Then‚ I prepared wet mount slides and direct staining slides of both S. epidermidis and L. acidophilus. to observe them microscopically using oil immersion lens. When I was done‚ I stored them in the refrigerator for future

Unknown #11: Citrobacter freundii Tryptic Soy Agar Test (TSA): TSA is a basic medium that is most similar to nutrient agar. The agar contains carbon‚ nitrogen‚ sodium chloride‚ and agar. This allows for the growth of a large variety of microorganisms to grow and ferment in the medium. Mannitol Salt Agar (MSA): MSA is a selective and differential medium that favors the growth of salt loving organisms. It is commonly used to distinguish the different species of Staphylococci.
