The most resistant microorganisms to chemical biocides are gram-negative ones.
What types of bacteria are Gram-negative?
Pseudomonas, Klebsiella, Proteus, Salmonella, Providencia, Escherichia, Morganella, Aeromonas, and Citrobacter are examples of Gram-negative organisms that are frequently isolated.
What makes Gram-negative bacteria unique?
- Antibiotics are highly resistant to gram-negative bacteria. They rank among the most pressing global public health problems.
- Gram-negative bacteria have the capacity to bring about a wide range of illnesses in people. Nearly all of the organ systems are accessible to them.
How do Gram positive and Gram negative bacteria differ from one another?
- While gram-negative bacteria lose crystal violet and stain red, gram-positive bacteria retain crystal violet and stain purple.
- Gram staining can thus be used to distinguish between the two types of bacteria. Due to their thick cell walls, gram-negative bacteria are more resistant to antibodies.
