Study Notes
Bacterial Pathogens
- Bacillus anthracis: A Gram-positive bacillus that causes anthrax, a serious infectious disease affecting animals and humans.
- Mycobacterium: A genus of acid-fast bacteria, including Mycobacterium leprae (cause of leprosy) and Mycobacterium tuberculosis (cause of tuberculosis).
Viral Pathogens
- Varicella-Zoster Virus (VZV): Causes chickenpox and shingles, a reactivation of the virus later in life.
- Measles virus: Known for its characteristic Koplik's spots (small white spots inside the mouth) and is preventable by the MMR vaccine.
- Human Papilloma Viruses (HPV): A group of viruses associated with warts (skin growths) and sexually transmitted infections.
Other Pathogens
- Vibrio vulnificus: A Gram-negative curved rod, known to infect through contact with raw oysters.
- Malassezia: A genus of fungi responsible for fungal infections, often described as "spaghetti & meatballs" under the microscope.
- Staphylococcus aureus: A bacterium that can cause scalded skin syndrome (SSSS) due to the production of exfoliative toxin.
Bacterial Toxins
- Clostridium: A spore-forming bacterium that causes tetanus, a serious illness characterized by muscle spasms.
- Streptococcus pyogenes: A Gram-positive bacterium that forms chains and is responsible for necrotizing fasciitis, also known as flesh-eating bacteria.
Bacterial Infections
- Bacillus anthracis is a gram-positive bacillus that is the causative agent of anthrax
- Mycobacterium is an acid-fast genus that contains the causative agents of tuberculosis (Mycobacterium tuberculosis) and leprosy (Mycobacterium leprae)
Viral Infections
- Varicella-zoster virus (VZV) causes both chickenpox and shingles
- Measles is a viral infection that manifests in Koplik's spots and is preventable by the MMR vaccine
- Human papillomaviruses (HPVs) can cause a range of skin conditions, including warts, and are recognized as sexually transmitted infections
Other Infections
- Vibrio vulnificus is a gram-negative curved rod that can infect the skin through contact with oysters
- Malassezia is a fungal species that causes skin infections; its characteristics resemble "spaghetti and meatballs"
- Staphylococcus aureus is a bacterium that causes scalded skin syndrome as a result of the exfoliative toxin it produces
- Clostridium is a spore-forming bacterium that is best known for its causative role in tetanus
- Streptococcus pyogenes is a gram-positive chain-forming bacterium that facilitates the development of necrotizing fasciitis
