Give the reason why is an organism such as Staphylococcus adapted to growth on the human skin but the streptococci are generally not shows?
Step by step
Solved in 2 steps
- Why is an organism such as Staphylococcus adapted to growth on the human skin whereas the streptococci are generally not?Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be normal and beneficial but also be pathogenic?Explain why the media where the Staphylococcus aureus is plated has turned yellow but the media where Staphyloccocus epidermidis plated is still pink? The media used would be the Mannitol Salt Agar Medium.
- Direct contact with pathogenic microorganisms is the most common cause of hospital-acquired infection. How might a dermal (skin) Staphylococcus infection of a staff member result in a urinary traction infection of a patient? Describe possible pathways of contamination during a normal workday.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.which cell in the human body does Staphylococcus aureus make pores.
- A hospital lab technician working with a particular strain of streptococci culture on blood agar plates suddenly came down with a case of sore throat. Using Koch's Postulates as a guide, develop a step by step experimental protocol to determine if the organism growing on the plates was in fact the cause of the technician's sore throat.With your tests you now figured out that your patient has a Staphylococcus infection, and you would like to know if the infection is caused by Staphylococcus aureus or by Staphylococcus epidermis. What test can you do next to see if your patient indeed has a Staphylococcus aureus infection? O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus aureus can ferment mannitol turning the agar plate yellow. Staphylococcus erpidermis cannot ferment mannitol and the agar plate stays red. O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus epidermis can ferment mannitol turning the agar plate yellow. Staphylococcus aureus cannot ferment mannitol and the agar plate stays red. O There is no way you can distinguish between Staphylococcus aureus and Staphylococcus erpidermis O you do a Gram stain. Staphylococcus aureus will stay purple as it is Gram positive and Staphylococcus erpidermis will show up as…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.
- Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be part of the normal microbiome and beneficial but also be pathogenic?Under what conditions does Staphylococcus epidermidis become an opportunistic pathogen? Group of answer choices S. epidermidis can form biofilms on devices inserted into patients during surgery. S. epidermidis becomes pathogenic when it overgrows in the throat. S. epidermidis becomes pathogenic when it produces Shiga toxin. S. epidermidis becomes a pathogen whenever a patient has untreated diabetes.Please help me answering this question What medium would you use (EMB, SBA, MSA) to distinguish Streptococci based on hemolytic activity? Describe what you would see on the medium for Streptococcus pyogenes.
