Antimicrobials Flashcard Deck - 10 Cards

Flashcard 1: What is the common treatment for all rickettsial diseases?

Answer: doxycycline

Flashcard 2: What are the two most characteristic toxicities associated with aminoglycosides?

Answer: Ototoxicity (Cranial Nerve VIII damage) and Nephrotoxicity

Flashcard 3: tetracyclines

Answer: discolored teeth

Flashcard 4: What is the mechanism of action of Antimycin A?

Answer: Inhibits Complex III of the Electron Transport Chain (ETC)

Extra: Antimycin A blocks the transfer of electrons from cytochrome b to cytochrome c1, effectively inhibiting the Electron Transport Chain and oxidative phosphorylation.

Flashcard 5: What is the mechanism of action of Cyanide?

Answer: Inhibits Cytochrome c oxidase (Complex IV) of the Electron Transport Chain, stopping oxidative phosphorylation.

Extra: Cyanide binds to the ferric (Fe3+) iron in cytochrome a3, preventing the final transfer of electrons to oxygen. Treatment: Nitrites (to create methemoglobin), Thiosulfate, or Hydroxocobalamin.

Flashcard 6: Mechanism of action of Rotenone?

Answer: Inhibits Complex I of the Electron Transport Chain (ETC)

Extra: Rotenone (pesticide), Amobarbital (barbiturate), and MPP+ inhibit Complex I. This prevents the transfer of electrons from NADH to Coenzyme Q, thereby inhibiting oxidative phosphorylation.

Flashcard 7: What is the mechanism of action of Oligomycin?

Answer: Blocks ATP synthase (Complex V) \u2192 Inhibits oxidative phosphorylation

Extra: Oligomycin binds to the FO subunit of ATP synthase, preventing protons from flowing back into the mitochondrial matrix. This leads to a stop in ATP synthesis and a secondary inhibition of the electron transport chain due to the buildup of the proton gradient.

Flashcard 8: Mechanism of action of 2,4-dinitrophenol (2,4-DNP)?

Answer: Uncoupler of oxidative phosphorylation.

Extra: 2,4-DNP increases the permeability of the inner mitochondrial membrane to protons. This dissipates the proton gradient, allowing electron transport to continue while inhibiting ATP synthesis (uncoupling). The energy is instead released as heat.

Flashcard 9: What is the mechanism of action of Trimethoprim (TMP)?

Answer: Inhibits prokaryotic dihydrofolate reductase

Extra: Trimethoprim (TMP) is often used in combination with Sulfamethoxazole (SMX) to inhibit sequential steps in bacterial folic acid synthesis. TMP inhibits dihydrofolate reductase, while SMX inhibits dihydropteroate synthase.

Flashcard 10: Sulfonamides, methotrexate, IV acyclovir, and triamterene are agents that can _____ in renal tubules, causing renal failure

Answer: precipitate

About Antimicrobials Flashcards for USMLE

These Antimicrobials flashcards are designed for USMLE Pharmacology preparation, using active recall to help you retain high-yield concepts, clinical correlations, and commonly tested facts. Each card prompts you to retrieve information from memory rather than passively reviewing notes, which research shows leads to significantly better exam performance.

The 896 cards in this deck cover the most important topics in Antimicrobials, including key mechanisms, diagnostic criteria, treatment protocols, and clinical pearls that frequently appear in USMLE examinations. Cards are organised by chapter so you can focus on specific areas or work through the entire topic systematically.

For personalised spaced repetition scheduling that adapts to your performance, unlimited flashcards, and detailed progress analytics, download the Oncourse app.

Frequently Asked Questions

Are Antimicrobials flashcards free on Oncourse?

Yes, completely free. You can study all 896 Antimicrobials flashcards on this page at no cost. For spaced repetition scheduling and progress tracking, download the Oncourse app.

How do flashcards help with USMLE preparation?

Flashcards use active recall — instead of passively re-reading notes, you retrieve information from memory. Research shows this builds stronger, longer-lasting memories and is one of the most effective study strategies for medical exams like USMLE.

How many Antimicrobials flashcards are available?

There are currently 896 flashcards for Antimicrobials under Pharmacology, organised by chapter. New cards are added regularly to cover the latest USMLE syllabus.

Can I study Antimicrobials flashcards by chapter?

Yes. The flashcards are organised by chapter so you can focus on specific areas or work through the entire topic systematically. Scroll down to the "Study by Chapter" section to pick a chapter.

What topics do these Pharmacology flashcards cover?

The cards cover high-yield concepts, clinical correlations, diagnostic criteria, treatment protocols, and commonly tested facts from Antimicrobials. They mirror the depth and style of USMLE questions.
