24 Questions
What differentiates formig from staph on blood agar in terms of their ability to lyse RBCs?
Formig can lyse RBCs completely, while staph can only cause incomplete lysis.
Why is it important for patients to finish the course of antibiotics (ABX) as prescribed?
Discontinuation of ABX can lead to prolonged illness and potential kidney damage.
Which bacterium is susceptible to treatment with beta-lactamase antibiotics?
Group A strep
What characteristic differentiates Group A strep from Staph aureus in terms of antibiotic resistance?
Group A strep is susceptible to beta-lactamase antibiotics, while Staph aureus is resistant.
What can happen if serum levels of bacteriocidal antibiotics are not maintained at the required levels?
The bacterial infection may persist and result in prolonged illness.
Why is it crucial for patients to adhere to the prescribed antibiotic regimen?
Non-compliance can potentially lead to increased mortality rates due to systemic complications.
What is the main difference between Group A strep and Staph aureus in terms of their interaction with antibodies on blood agar plate?
Incomplete lysis for Group A strep, complete lysis for Staph aureus
What consequence can arise from discontinuation of antibiotics (ABX) before completing the course?
Prolonged illness and potentially kidney damage
Why is it essential to maintain bacteriocidal antibiotic levels in the blood during treatment?
To ensure complete eradication of the pathogen
How does Group A strep differ from Staph aureus in terms of antibiotic resistance?
Group A strep is susceptible to beta-lactamase antibiotics, Staph aureus is not
In what scenario might serum levels of bacteriocidal antibiotics become critical?
For full eradication of the pathogen
What danger can arise if Enterococci become resistant to vancomycin?
Limited treatment options due to vancomycin ineffectiveness
How does Strep pneumoniae resistance to beta-lactamase antibiotics compare to Enterococci resistance?
Strep pneumoniae can become resistant to beta-lactamase antibiotics but not Enterococci
What is the consequence of discontinuing antibiotics (ABX) before completing the course?
Increasing the mortality rate
In what way does Group A strep differ from Staph aureus in terms of their interaction with antibodies on blood agar plate?
Group A strep causes complete lysis
What is the main difference between Strep pneumoniae and Enterococci in terms of their resistance to antibiotics?
Enterococci are resistant to B lactamase antibiotics
Why is it important for patients to maintain bacteriocidal antibiotic levels in their blood during treatment?
To fully eliminate the infectious agent
Which bacteria is susceptible to treatment with beta-lactamase antibiotics?
Group A strep
What can happen if Enterococci become resistant to vancomycin?
Prolonged illness potentially leading to kidney damage
In what scenario might serum levels of bacteriocidal antibiotics become critical?
When discontinuation of ABX can cause prolonged illness
What differentiates Group A strep from Staph aureus on blood agar in terms of their interaction with antibodies?
Incomplete lysis on blood agar plate
How does Strep pneumoniae resistance to beta-lactamase antibiotics compare to Enterococci resistance?
Enterococci are more resistant than Strep pneumoniae
What consequence can arise from inadequate compliance with ABX therapy?
Prolonged illness potentially leading to kidney damage
Why is it crucial for patients to maintain bacteriocidal antibiotic levels during treatment?
To fully eliminate the bacterial infection and prevent complications
