    Study Notes

    Types of Infections

    • An infection with no detectable symptoms is described as asymptomatic.
    • A polymicrobial infection occurs when one organism initiates the infection, but two or more bacteria infect the same tissue.

    Opportunistic Infections

    • An opportunistic infection is caused by an organism that generally does not cause disease unless normal host defenses are compromised.

    Virulence Factors

    • Virulence factors are properties of bacteria that enable them to establish infection and cause disease.

    Latent Infections

    • A reactivation infection occurs when a latent infection becomes active again.

    Fulminant Infections

    • A fulminant infection is a severe and rapidly progressing infection that often has a poor outcome.

    Iron Sequestering

    • Siderophores enable bacteria to sequester iron from their environment, which is essential for their growth and survival.

    Overcoming Host Defenses

    • Bacteria can overcome host defenses during the infectious process by producing virulence factors, such as adhesins, invasins, and toxins.
