Pseudomonas Luteola: Habitat & Identification

Instructor: Derrick Arrington

Derrick has a master's degree in science education and has taught at the high school and community college level for 13 years.

We live in a world covered with microorganisms. Many of these organisms are good for humans while others can cause serious problems. In this lesson, we will explore the bacterium known as Pseudomonas Luteola.

Introduction to Bacteria

The first extensive use of the microscope began in the 1600s. As technology has improved over time scientists have discovered thousands of microorganisms that share the planet with us. Many of these organisms are classified as bacteria. A bacterium is a single celled organism that has a cell wall that lacks organized cellular organelles such as a defined nucleus. Many bacteria are pathogenic. The term pathogenic refers to the ability of these bacteria to cause disease. Pseudomonas Luteola is a prime example of a pathogenic bacterium.

Characteristics of Pseudomonas Luteola

This bacteria is known by microbiologists to be a rod-shaped bacteria, more specifically called a bacilli. This particular type of bacteria is also classified as gram-negative. A gram-negative bacterium is one that has a thin cell wall composed of the material called peptidoglycan. Due to the presence of this material they are known to shed the violet stain in the gram staining procedure which results in a characteristic red color. This type of bacteria is also motile. Motility describes he ability of some bacteria to move spontaneously with the expenditure of energy. Pseudomonas Luteola moves with the assistance of long whip-like tails known as flagella.

When viewed through a microscope this bacteria is between 0.8 and 2.5 micrometers in length and produces a yellow to orange pigment.

Habitat of Pseudomonas Luteola

Pseudomonas Luteola are very versatile. They can be found in numerous locations and thrive at temperatures around 30 degrees Celsius. They do require a moist area with the availability of oxygen. This includes soils, water surfaces, and the human body. This bacterium is known to inhabit solutions of distilled water, disinfectants, and intravenous solutions. This requires that hospitals maintain extremely sterile environments in both the housekeeping departments and pharmacy to reduce the risk of exposure to Pseudomonas Luteola. Once inside the body this bacteria is known to cause inflamation of the organ system that it invades along with septicemia, or infection of the blood.
