43 cards
Card 1
Question: According to the document, which antibiotics are gram-positive bacteria generally expected to be resistant to?
Answer: Aztreonam, temocillin, polymyxin B/colistin, and nalidixic acid.
Card 2
Question: What is the expected resistance of Staphylococcus saprophyticus to fusidic acid, aminoglycosides, and macrolides?
Answer: Resistant (R) to fusidic acid, aminoglycosides, and macrolides.
Card 3
Question: According to the table, what resistance does Streptococcus spp. show?
Answer: Resistant to ceftazidime, cephalosporins (except ceftazidime), and clindamycin.
Card 4
Question: What resistance pattern does Enterococcus faecalis exhibit in the table?
Answer: Resistant to ceftazidime, cephalosporins (except ceftazidime), aminoglycosides (LLR), clindamycin, quinupristin-dalfopristin, vancomycin, teicoplanin,
Card 5
Question: What notable resistance characteristics does Enterococcus faecium have in the table?
Answer: Resistant to ceftazidime, cephalosporins (except ceftazidime), aminoglycosides (LLR plus AAC(6')-I), quinupristin-dalfopristin, and vancomycin/teicopl
Card 6
Question: What does the abbreviation LLR indicate regarding aminoglycosides in enterococci?
Answer: LLR stands for low-level resistance to aminoglycosides; combination with cell wall inhibitors is synergistic if high-level resistance is not present.
Card 7
Question: What effect does the chromosomal enzyme AAC(6')-I have in Enterococcus faecium?
Answer: It causes a loss of synergy between aminoglycosides (except gentamicin, amikacin, and streptomycin) and penicillins or glycopeptides.
Card 8
Question: According to the document, what general resistance do anaerobes exhibit?
Answer: They are typically resistant to aztreonam, aminoglycosides, polymyxin B/colistin, and nalidixic acid.
Card 9
Question: Which Clostridium species are mentioned as resistant to vancomycin?
Answer: Clostridium ramosum and Clostridium innocuum are resistant to vancomycin.
Card 10
Question: What additional resistances are expected in Enterobacterales and Aeromonas spp., beyond those listed in the tables?
Answer: Resistance is also expected to benzylpenicillin, glycopeptides, lipoglycopeptides, fusidic acid, macrolides (with exceptions), lincosamides, streptogr
