    Study Notes

    Toxemic Infections

    • Toxemic infections are caused by toxins produced by bacteria, rather than the bacteria themselves.
    • Examples include botulism, diphtheria, and relapsing fever.
    • Psittacosis, typhus, and tuberculosis are not toxemic infections.

    Coiled Bacteria

    • Francisella does not have coiled bacteria.
    • Treponema, Borrelia, and Leptospira are genera with coiled bacteria
    • Streptococcus are not coiled bacteria.
    • Neisseria are not coiled.

    Important Bacteria Genera

    • Gram-positive rods include Clostridium, Corynebacterium, and Mycobacterium.
    • Gram-negative rods include Escherichia and Salmonella and others.
    • Gram-negative cocci are part of the Neisseria genus.
    • Gram-positive cocci are part of the Streptococcus and Staphylococcus genera.

    Vaccinations

    • Vaccination is given in the case of Pertussis, diphtheria, tetanus, and others.
    • Vaccination is not given in the case of Relapsing fever, Tularemia, Typhus. and others.

    Additional Information

    • Some bacteria, like Streptococcus pneumoniae, have a capsule as a virulence factor.
    • Bacterioscopy is a microscopy technique used to examine bacteria.
    • Some types of bacteria, like Clostridia, form spores for survival in unfavorable conditions.
