journey started out with a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with me on the journey to the unknown. As I recall from earlier that semester‚ the first test that needed to be performed was the

There are several genera of micro-organisms related to contact lens storage case contamination. Unlike CL contamination which is bacterial in nature‚ storage case contamination is often polymicrobial.(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
