Some Like it Hot: Efficiency of the Type III Secretion System has Multiple Thermosensitive Behaviours in the Pseudomonas syringae Complex We characterised the role of temperature on T3SS efficiency in P. syringae, showing that bacterial behaviour in response to temperature is highly variable among strains, even among very closely relat...

U01.03.016 Features of exotoxins and endotoxins Match each bacterial exotoxin to its causative organism and mechanism of pathogenesis. Focus on how these toxins act at the cellular level — whether they block neurotransmission, inhibit protein synthesis, or alter intracellular signaling (like cAMP). Understanding these mechanisms is essential for mastering microbiology concepts in USMLE Step 1 and clinical reasoning.

U01.03.013 Bacterial virulence factor Bacterial virulence factors are specialized molecules or structures that enable bacteria to colonize hosts, evade immune responses, and cause disease. These include capsules, toxins, adhesins, enzymes, and secretion systems that enhance pathogenicity and determine disease severity.

RfaH protein shields bacteria, helping infections persist

Loss of the RfaH protein cut infection rates in mice from nearly 100% to about 20%, according to a study in mBio. Read more: getnews.me/rfah-protein-shields-bac... #rfah #bacterialvirulence #microbiology
