Host-pathogen interactions

High-yield summary Core concept Host-pathogen interactions determine infection outcomes: clearance, persistence, latency, or disease. Immune responses are tailored to pathogen type Pathogens evolve mechanisms to evade immunity.   Extracellular bacteria Innate Response Complement activation (Alternative and lectin pathways) Phagocytosis via PRRs, Fc receptors, complement receptors Inflammatory cytokines: IL-1, TNF, IL-6 Adaptive Response Antibodies: Opsonization, toxin neutralization CD4+ […]

Hepatitis

Learning goals Differentiate the viral structure, mode of transmission, epidemiology, and risk of chronic infection for viral hepatitis caused by hepatitis A, B, C, D and E Use clinical presentation and laboratory testing, including serology and molecular testing (PCR), to distinguish acute infection, chronic infection, resolved infection, and post-vaccination for hepatitis A, B, and C […]

Introduction to viruses

High-yield summary Viral structure and classification  All viruses contain genetic material (DNA or RNA, never both) and a protein capsid.  Some viruses have an envelope derived from the host cell membrane.  Classification by genetic material: DNA viruses (e.g., Herpesviridae, Adenoviridae) and RNA viruses (e.g., Orthomyxoviridae, Retroviridae).  Baltimore Classification groups viruses based on their replication strategy […]

Parasitology 2: GI helminths

Learning goals Compare and contrast the epidemiology, clinical features, diagnosis, treatment and prevention of common intestinal roundworms and tapeworms including Enterobius, Ascaris, Ancylostoma (hookworm), Strongyloides, Taenia solium, Echinococcus, and Diphyllobothrium Describe the pathogenesis and type of anemia related to heavy hookworm infections Describe the epidemiology, pathogenesis, and clinical features of Strongyloides hyperinfection Compare and contrast […]

Introduction to vaccines

High-yield summary Types of vaccines  Live Attenuated: Replicates, broad immune response, contraindicated in immunocompromised and pregnancy  Inactivated: No replication, safer for immunocompromised and pregnancy  Polysaccharide and Conjugate: Capsule-targeted, age-dependent response, T-cell independent/dependent  Protein Subunit: Toxoids, VLPs, recombinant proteins  Viral Vector: Recombinant expression in vivo, adenovirus/VSV  Nucleic Acid: mRNA/DNA vaccines, e.g., COVID-19 vaccines    Immunology and […]

Other therapies

Albendazole (Albenza) Class(es) Anthelmintic Clinical use(s) FDA approved: echinococcosis, neurocysticercosis. Off-label/clinical use: Ascariasis, capillaria, clonorchiasis, giardiasis, microsporidia (HIV), hymenolepis nana infection, loa loa, trichuriasis. Mechanism(s) of action Causes parasitic death by binding to colchicine-sensitive site of beta tubulin inhibiting their polymerization into microtubules. Key adverse effects Abdominal pain, headache, abnormal liver function tests, N/V, SJS. […]
