Several tests were accomplished technically and carefully to identify the unknown # 230 to be M.luteus bacteria. Most of the observed results do match the expected ones, except two tests. The observed results for glucose fermentation and oxidase test did not match the expected results.
The expected result for fermentation of glucose test was negative while the observed result was positive. Conversely, in Kligler iron agar media, which exams the ability of bacteria to ferment lactose and glucose, M.Luteus gave negative outcome which matches the expected result. Thus, I repeated the Kligler iron agar to test if M.Luteus can ferment glucose and I obtained same result which is negative. Getting positive result for glucose in beginning could be …show more content…
Usually M.Luteus is found in environments where the temperature is around 37 °C [3]. Also, M. Luteus is aerobic microorganism which favor oxygen environment which can be easily found on the mucosal linings of the upper pharynx, human mouth, and respiratory tract. M. Luteus can grow well in environments with little water or high salt concentrations. On human skin, M.Luteus breaks down compounds in sweat into compounds with bad odor. Also, it can be easily grown on Simmon 's citrate agar or on inorganic nitrogen agar. Moreover, M. Luteus found in soil, air, and it is part of the human skin flora. Also, M. lutes is known for its growth in dairy products which can be transmitted through consumption of milk [3]. Thus, the ideal environment for M.Luteus is aerobic habitat with 37 C temperature.
M.luteus rarely causes infectious diseases in human, but it is an opportunistic pathogen for immunosuppressed patients, such as HIV patients [4].Thus, M.luteus is associated with different diseases which are recurrent bacteremia, meningitis, septic shock, septic arthritis, endocarditis, and cavitating pneumonia in immunosuppressed patients. Also, this bacteria is associated with urinary tract infections. M.Luteus is known for its extremely low virulence, and it is usually considered
