Gram-negative bacteria are a significant cause of infections acquired in both hospital and community settings, resulting in a high mortality rate worldwide. Currently, a Gram-negative infection is diagnosed by symptom evaluation and is treated with empiric antibiotics which target both Gram-negative and Gram-positive bacteria.
Most bacteria are classified into two broad categories: Gram positive and Gram negative. These categories are based on their cell wall composition and reaction to the Gram stain test. The Gram staining method, developed by Hans Christian Gram , identifies bacteria based upon the reaction of their cell walls to certain dyes and chemicals.

Metrics details. The highest proportion of susceptible A. Vancomycin-resistant VR isolates represented 1. Highest percentages of VR. Isolates were collected from patients with an infectious disease and identified as the causative agent according to laboratory criteria.
In clinical microbiology, phenotypic typing schemes particularly Gram staining are some of the most common and effective techniques for bacteria identification. Discovered in , Gram stain technique has proven to be one of the most useful phenotypic classification systems through which bacteria can be identified based on their staining properties and general morphology. Using this technique, bacteria are classified as either Gram positive or Gram negative. Bacteria are single-celled prokaryotes ubiquitous in nature. As such, they can be found in different types of environments ranging from aquatic to the hot rocks of the Mojave Desert. In these environments, bacteria may exist as free-living organisms making their own food or feeding on dead organic matter etc , in symbiosis with other organisms e.

Comparison of Gram Positive and Gram Negative. Bacterial Strains Cloned with Different Types of. Luciferase Genes in Bioluminescence. Cytotoxicity Tests*.
Gram-negative bacteria are classified by the color they turn after a chemical process called Gram staining is used on them. Gram-negative bacteria stain red when this process is used. Other bacteria stain blue. They are called gram-positive bacteria. Gram-negative and gram-positive bacteria stain differently because their cell walls are different.
