(Classical and Genetical Classification and Characterization of Bacterial Contamination on Valid and Expired Drugs and Cosmetics)
-Students tested different groups of valid and expired drugs and cosmetics as 9 types of Maskra, 3 types of eye drops, Salvix, Tosicsn and Rose Water
-Students used different types of means to isolate bacterial contamination on expired cosmetics and drugs as Nutrient Agar, EMB and Manetol Salt Agar
-Slide preparations for different types of bacteria and testing for grame positive and negative bacteria
-Using CX31microscope supported with live camera to examine prepared slides
-The bacterial contamination is E.Coli, Micrococcus Lutius, Staphylococcus Aureus, Psedumonas and Lactobacillus
-Preparation serial dilutions and test the bacterial concentrations (Turbidmetric test)
Now, students are preparing samples for validity test, colony counting, sensitivity tests and molecular identification next weeks
