Aerobic Gram Negative bacilli Flashcards
What are Aerobic Gram-Negative Non-enteric Bacilli?
A large, diverse group of non-spore-forming bacteria
They inhabit a wide range of environments including large intestines, zoonotic sources, respiratory systems, soil, and water.
Where do Aerobic Gram-Negative Non-enteric Bacilli commonly inhabit?
Large intestines, zoonotic sources, respiratory systems, soil, water
These habitats indicate their ecological diversity.
What unique component do all Aerobic Gram-Negative Non-enteric Bacilli possess in their cell wall?
Outer membrane lipopolysaccharide (endotoxin)
This component can trigger immune responses in humans.
What is the gram status of Pseudomonads and its shape?
Small gram-negative rods with a single polar flagellum
Pseudomonads are a group of bacteria known for their diverse metabolic capabilities.
Where are Pseudomonads primarily found?
In soil, sea water, and fresh water; also colonize plants and animals
They thrive in various environments, making them versatile organisms.
What role do Pseudomonads play in the ecosystem?
Important decomposers and bio-remediators
They help break down organic material and can be used to clean up environmental contaminants.
Other then their main habitat, where else is Pseudomonads commonly found?/ commonly contaminate?
Homes and clinical settings
## Footnote
Their presence can be problematic, particularly in healthcare settings.
What type of respiration do Pseudomonads use?
Aerobic respiration; they do not ferment carbohydrates
This distinguishes them from many other bacteria that can ferment sugars.
What enzymes do Pseudomonads produce?
Oxidase and catalase
These enzymes are important for their metabolic processes.
Why are some Pseudomonads green?
Because of the Water soluble pigments they produce
This characteristic often gives them a green coloration.
Pseudomonads are known for being _______.
Free living
They do not require a host to survive.
What is a common visual characteristic of some Pseudomonads?
Green moving, free living cleaners
Their ability to produce pigments contributes to their coloration.
