Lecture on Aerobic Gram-Negative Bacilli

These flashcards cover key terminology and concepts related to Aerobic Gram-Negative Bacilli discussed in the lecture.

Aerobic Gram-Negative Nonenteric Bacilli

A large, diverse group of non-spore-forming bacteria with a wide range of habitats including large intestines, zoonotic environments, respiratory, soil, and water.

Pseudomonas aeruginosa

An opportunistic pathogen that is a common inhabitant of soil and water, known for its resistance to disinfectants and drugs.

Brucella

Tiny gram-negative coccobacilli responsible for brucellosis, a zoonosis transmitted to humans from infected animals.

Bordetella pertussis

Encapsulated coccobacillus that causes whooping cough, primarily affecting children and transmitted by direct contact or inhalation.

Legionella pneumophila

Bacterium responsible for Legionnaires' disease and Pontiac fever, widely distributed in water and associated with amoebas.

Enterobacteriaceae Family

A large family of small, non-spore-forming gram-negative rods, many of which inhabit soil, water, and the intestines of animals, important in causing diarrhea.

Opportunistic pathogens

Microorganisms that are normally non-pathogenic but can cause disease in individuals with weakened immune systems.

Zoonotic pathogens

Pathogens that can be transmitted from animals to humans.

Endotoxin

A component of the outer membrane of Gram-negative bacteria, often responsible for the toxic effects seen during infections.

Biofilms

Thin, slimy films of bacteria that adhere to surfaces, often associated with antibiotic resistance in clinical settings.
