Aerobic Non-spore-forming Gram-Positive Bacilli

The flashcards cover key vocabulary and concepts related to aerobic non-spore-forming gram-positive bacilli, focusing on Listeria monocytogenes, Corynebacterium, Bacillus anthracis, and their clinical significance.

Listeria monocytogenes

A facultative intracellular parasite associated with foodborne illness.

Virulence mechanisms

Strategies used by pathogens to infect and damage host organisms.

Hemolysin

A substance that causes the destruction of red blood cells, used by Listeria monocytogenes to damage phagosome membranes.

Gastroenteritis

Inflammation of the stomach and intestines, often resulting in vomiting and diarrhea.

Gram stain

A bacterial staining technique that differentiates bacteria into gram-positive and gram-negative.

Corynebacterium diphtheriae

Bacterium responsible for diphtheria, characterized by toxin production.

Toxin production

The process by which bacteria produce poisonous substances that can damage host tissues.

Pharyngitis

Inflammation of the throat, often resulting in a sore throat.

Mycetoma

A chronic granulomatous disease characterized by tumor-like swellings, often affecting the skin.

Bacillus anthracis

The bacterium that causes anthrax, notable for spore formation and virulence factors.

Pulmonary anthrax

A form of anthrax infection caused by inhalation of spores, leading to severe respiratory illness.

DTaP vaccine

A vaccine for children under 7 years old that protects against diphtheria, tetanus, and pertussis.

Antitoxin

A substance that neutralizes toxins in the body, used in treating diphtheria.

Opportunistic pathogens

Microorganisms that cause disease primarily in individuals with compromised immune systems.
