i really need help finding out how they got 12.5 and explain so I can understand step by step
Step by step
Solved in 3 steps
- I AM TRYING TO IDENTIFY THIS UNKNOWN. IMAGE 1 HAS TWO PICTURE OF CATALASE TEST AND BLOOD AGAR TEST. I believe it is one of the following: 1) S. pyo. 2)S. agal . 3)S.pneu. 4)E. faecalis 5)S. aureus 6)S epi. 7)S. sapro. 8)M. luteus Please let me know which test will i need out of the table to justify your reason of picking up the unknown and also how that test justifies it? what characteristics of that test made you pick the unknown?You are working in a lab studying Streptococcus pyogenes as a cause of necrotizing fasciitiis. You have an overnight culture that you want to know the starting concentration of, so do a set of six 1:10 serial dilutions (putting 1 mL from the stock into a 9 mL blank), with tube #1 being 1:10, #2 is 1:100, etc. You plate 0.1 mL from tube 5 onto a blood agar plate and the next morning count 134 colonies. How many bacteria (measured in CFU/mL) were in the overnight culture flask? A. 1.34 x 10^4 CFU/mL B. 1.34 x 10^5 CFU/mL C. 1.34 x 10^6 CFU/mL D. 1.34 x 10^7 CFU/mL E. 1.34 x 10^8 CFU/mL F. cannot tell based on the data given - you'd need to know the volume of the original culture flaskEx. 17: Chemotherapeutic Agents Using the Antimicrobial Susceptibility Table on pg 62 in the lab manual, determine whether not the bacteria plated in this Kirby-Bauer test are resistant (R), intermediate (I), or susceptible (S). The bacterial species tested was Escherichia coli (Gram negative). Ciprofloxacin Diameter = 20 Streptomycin Diameter 30 Carbenicillin Diameter 17 + Erythromycin Diameter = 23 Novobiocin Diameter = 0 bacterial growth = disk with antibiotic (see labels) = no growth

Process to kill or remove pathogenic microorganism (not spores) C. Asepsis 3. Organism capable of multiplication D. Decontamination 4. Process to kill/remove all microorganisms including spores and viruses E. Pathogen 5. Thick-walled resting cells formed by Gram+ organisms F. Infection 6. Organism able to cause disease in a host G. Disinfection 7. Suspension in air of finely dispersed solids or liquids H. Viable microorganisms 8. Caused by inhaling airborne material carrying microbial contaminants I. Sterilization 9. Prevention of microbial contamination J. Spores (bacterial) 10. Disinfection or sterilization of contaminated articlesdiameter AM=47MM TE= 27 MM both left hand side is ampicillin and right hand side is tetracycline With reference to the table below, determine the antibiotic susceptibilities of different antibiotics against coli and S.aureus. S.aureus Antimicrobial agent Interpretive categories and zone diameter breakpoints, nearest whole mm sensitive Intermediate resistant Tetracycline >19 15-18 <14Choose one specific way from each of the two methods of inhibiting the growth of microbes below. Describe the method, explain the mechanism of action of killing the microorganisms and give practical applications of your chosen ways. 1. Physical Methods - Heat, cold, dessication, radiation, ultrasonic waves, filtration, gaseous atmosphere 2. Chemical Methods- disinfectants, antiseptics
- A patient with a diagnosis of "Staphylococcal pneumonia" was admitted to the clinic. For successful etiological treatment we should select an effective antibiotic. For this purpose, was recommended to determine the antibioticogram of the pathogen. 1. What method can be used to determine antibiotic sensitivity? 2. The principle of the method and accounting for results.Name two methods of control of growth for Mycobacterium tuberculosis pathogen in a patient with the disease and when confronted with the pathogen outside of the host. Be careful to specify if it is a physical method or a chemical method (check lecture to differentiate these two). Control of growth means how would you deal with an infection related to a person as well as how would you minimize the presence of the bacteria on a surface or object.About becterial enzymes, it is CORRECT to affirm that: a). Some becterial enzymes can help the microbe fight the immune system, by destroying lgA.b). Coagulases are enzymes that use the host's fibrinogen and form a semi-solid get that isolates amd protects the bacteria.c). Some bacterial enzymes such as hyaluronidase can help the microble move through the host's tissus by destroying the tissue's components.d). Fibrolysin is an enzymes that can help from blood clots.
- Choose the false statement below. O Effective antimicrobials may not be used commercially because of their mode of delivery or the time it takes them to leave the body. O Decontamination of an object is not necessary if disinfection is done properly. O In general, acid fast bacteria are less sensitive to antimicrobials than are Gram-negative bacteria or fungi. Question 8 Choose the false statement below: O Using three different classes of antimicrobials in combination greatly decreases the chance of developing resistance because the drug resistance strategy for one is the same for others. O Drug resistance to antimicrobials has proven to be extensive against chemotherapeutics as well as other chemical antimicrobials. O Collateral damage is a term that refers to the killing of normal body flora as well as pathogenic bacteria when taking antimicrobials or antibiotics.N. benthamiana will be infiltrated with a solution containing OD600=0.3 of each experimental Agro containing construct and OD600=0.1 of p19. Calculate the volume of cultures (V construct; V p19) needed according to the formulas: V construct = V final × 0.3/OD600; V p19 = V final × 0.1/OD600. One mL of infiltrate is often enough to complete a small experiment. How to plan your final volume accordingly?both left hand side is tetracycline and right hand side is ampicillin With reference to the table below, determine the antibiotic susceptibilities of different antibiotics against coli and S.aureus.
