multiple techniques for identifying bacteria. Learning how to gram stain‚ use specific media such as MacConkey agar‚ and test antibiotics to see which antibiotic would react best against a specific organism. All these techniques helped me prepare for the final lab‚ identification of an unknown bacterium. For the final lab‚ I received the organism “6A”. To start identifying this organism‚ I did a gram-stain to identify if the organism is gram positive or negative. I created two slides to ensure that I did

Foster Professor Ray Ramirez BIOL 2420 December 5‚ 2014 Tuberculosis: Leading Disease Killer in the World Microbes orbit the world that is around us involving being in the air and on surfaces we may come in close contact with. In the medical terms‚ microbiology involves the study of microscopic organisms‚ bacteria‚ archaea‚ fungi‚ protozoa‚ algae‚ and multi cellular animal parasites (Baumann 3-5). It is important that we acquire knowledge of these subjects because there are many infectious diseases that

the occurrence of plasmids in arsenic resistant bacteria was more than that in the common bacteria. In the present study‚ fifty seven As resistant bacterial isolates were screened for presence of plasmids within and twenty nine of them were found positive. The size of the plasmid DNAs were between 4 to 11 kb. All the plasmid bearing isolates showed elevated tolerance towards arsenate and arsenite (MTC 400 mM and 20 mM respectively) while tolerance to other heavy metals like Cu2+‚ Cd2+‚ Cr2+ and Pb2+
