Gram-Negative Bacteria: A Comprehensive Guide

Description

Gram-negative bacteria are a type of bacteria that do not retain Gram stain, a differential staining technique used to distinguish between two large groups of bacteria: Gram-positive and Gram-negative. They have a unique cell wall structure that includes an outer membrane, making them more resistant to antibiotics than Gram-positive bacteria. Gram-negative bacteria are ubiquitous, found in soil, water, and on the skin and mucous membranes of humans and animals.

Associated Diseases

Gram-negative bacteria can cause a wide range of infections, including:

  • Pneumonia
  • Urinary tract infections (UTIs)
  • Sepsis (bloodstream infection)
  • Meningitis (brain and spinal cord infection)
  • Gastroenteritis (food poisoning)
  • Cholera
  • Typhoid fever
  • Gonorrhea
  • Pseudomonas infections (lung infections, wound infections)
  • Acinetobacter infections (hospital-acquired infections)

Did you Know ?

Gram-negative bacteria are responsible for approximately 50% of hospital-acquired infections in the United States.
