Step by step
Solved in 2 steps
- Recall the epidemiology and pathology of the medically importantorganisms in the genera Moraxella and Acinetobacter.Recall the four genera of bacteria that cause opportunistic infections and are physiologically similar to Pseudomonas.Hypothetically make the Dichotomous key for Micrococcus luteus, Bacillus subtilis, Bacillus, Megaterium, Bacillus cereus, E.coli, Serratia Marcescens, and Enterobacter aerogenes based on colony morphology. Starting from the results of gram staining, catalase tests, (lactose, sucrose and glucose fermentation tests) and other biochemical tests for their accurate identification.
- In detail, discuss the morphological characteristics of the following bacteria. Corynebacterium pseudotuberculosis Corynebacterium striatum Corynebacterium ulcerans Corynebacterium urealyticum include references.Explain how PEMBA (polymyxin-pyruvate-egg yolk-mannitol-bromthymol blue-agar) is used to isolate, differentiate and enumerate Bacillus cereus from food sample.Selective and Differential Conditions of media and culture conditions can be used to culture and identify Listeria monocytogenes. For each, characterize it as Available Hint(s) Res Adding antibiotics, such as nalidixic acid Adding high concentrations of salts, such as lithium chloride and sodium chloride Adding a pH indicator to detect fermentation of hamnose to acid Incubate at 30°C Detecting beta-hemolysis Adding antifungals, such as amphotericin B Differential Selective
- Consider that you are working as a laboratory technician in a local hospital and three patients at brought to the laboratory who present with the following: a)symptoms of toxic shock syndrome resulting from food poisoning b) symptoms of respiratory disease associated with the diphtheria toxin c) symptoms of a sexually transmitted disease resulting in the release of pulse from the genitals For each of these cases write the: 1. Name of the microorganisms responsible and 2. The morphological structure of the cells of this microorganismWhat did Streptococcus avoid characteristics and descriptions of laboratory procedures and method Streptococcus? Are the healthcare concerns, infections, and nosocomial infections discussed for genera Streptococcus? What does specific examples from Streptococcus genus discussed with regard to specific conditions and concerns and not only with an overview of the entire genus?List three reasons Bacillus spp. are of practical importance
- Describe the procedure for obtaining the minimuminhibitory concentration (MIC) for a chemical that isbactericidal for Escherichia coli. Contrast the action ofdisinfectants and antiseptics.Hypothetically draw the Dichotomous key for Bacillus subtilis, Bacillus, Megaterium, Bacillus cereus, M.Luteus, E.coli, Serratia Marcescens, and Enterobacter aerogenes based on colony morphology. Start the key from the gram stain, catalase tests, (lactose, sucrose and glucose fermentation tests) and other biochemical tests for their accurate identification.ORGANISMS: STENOTROPHOMONAS MALTOPHILIA Outline the presumptive and definitive characteristics for the laboratory identification of the bacterial species being presented.
