Gram Positive Bacteria
This is a short non-branching Gram-positive rod that grows in the cold, exhibits weak beta-hemolysis, and a positive CAMP test (synergistic hemolysis with S aureus).
What is Listeria monocytogenes?
This is a plasmid-mediated enzymes in Enterobacterales that hydrolyzes penicillins and cephalosporins treated with carbapenems (e.g. imipenem-cilastatin).
What are Extended-Spectrum Beta-Lactamases (ESBLs)?
This enveloped dsDNA virus causes gingivostomatitis, cold sores, keratoconjunctivitis, herpetic whitlow and temporal lobe encephalitis; establishes lifelong latency in trigeminal ganglia.

This beta lactam drug of choice is for resistant Gram negative infections
What is Spectrum of Carbapenems?
This is a thin coiled spirochete transmitted to humans through direct contact with urine-contaminated water or soil from animal reservoirs like rodents and dogs
What are Leptospira interrogans Transmission & Risk Factors?
This classic combination of organ lesions strongly suggests disseminated Nocardia infection in an immunocompromised host
What are cavitary lung lesions accompanied by a brain abscess
This toxic component of Lipopolysaccharide (LPS) located on the outer membrane of all Gram-negative rods that triggers severe fever, cytokine release, hypotension, and septic shock.
What is a Gram-Negative Endotoxin (Lipid A)?
This poxvirus skin infection is common in children and immunocompromised individuals, often presenting as firm flesh-colored domed papules with central umbilication
What is Molluscum Contagiosum?
This mechanism known as efflux of antibiotics via a transport pump is commonly associated with this antibiotic.
What are Tetracyclines?
This small obligate intracellular Gram-negative rod that infects host vascular endothelial cells leading to widespread cell injury and systemic blood vessel leakage
What is Rickettsia rickettsii Pathogenesis & Target Cell?
The ONLY bacterial capsule composed of a polypeptide (poly-D-glutamate) rather than polysaccharides, protecting the organism from phagocytosis
What is Bacillus anthracis?
This capsular polysaccharide that inhibits phagocytosis strongly associated with neonatal meningitis and pneumonia.
What is Escherichia coli K Capsule?
This causes Fifth disease (Erythema infectiosum with "slapped cheek" rash) acute adult arthralgias hydrops fetalis transient aplastic crisis in sickle cell disease and pure RBC aplasia with giant pronormoblasts in immunocompromised hosts
What are Parvovirus B19 Clinical Syndromes?
This antibiotic is also known as Clindamycin and its mechanism of action is to block peptide transfer at 50S ribosomal subunit.
What is a lincosamide?
This obligate intracellular organism transmitted by the Lone Star tick (Amblyomma americanum) that infects monocytes forming characteristic intra-cytoplasmic morulae
What is Ehrlichia chaffeensis Cellular Tropism?
This pathogen possesses short-chain mycolic acids that are NOT acid-fast; cultured on cystine-tellurite agar (forming black colonies) or Loffler medium (revealing metachromatic granules).
What is Corynebacterium diphtheriae?
These are the 5 A's of this lactose-fermenting gram negative bacteria.
What is "Aspiration pneumonia, Abscesses, Alcoholics, DiAbetics, CurrAnt jelly sputum?"
This pathogen is characterized by cough, conjunctivitis, and coryza, maculopapular rash spreading head-to-toe, and Koplik spots (blue-white spots with red halos on buccal mucosa opposite premolars).
What is Measles (Rubeola)'s Clinical Triad?
This antibacterial inhibits nucleic acid synthesis by disrupting DNA and can also be administered for GI and GU parasite
What is Metronidazole?
This molecular pathogenesis mechanism enables the causative organism to enter macrophages and spread to regional lymphatic tissue
What are Yersinia outer proteins (Yops)?
This pathogen possesses alpha toxin as one of its virulence factors.
What is Clostridium perfringens?
This gram negative bacterial pathogen has a high mutation rate.
What is E. coli?
This is an exception described as the "Enterovirus Rule" within Picornaviridae
What are Poliovirus, Echovirus, and Coxsackievirus being human enteroviruses whileRhinovirus and Hepatitis A Virus are NOT enteroviruses?
This is also known as Linezolid, inhibits protein synthesis by binding to 50S ribosomal subunit, and its toxicity is associated with Serotonin Syndrome.
What is Oxazolidinone?
This pathogen is known as Francisella tularensis is treated with what antibacterial.
What is Streptomycin?
