Significance of Gram-negative bacilli
Gram-negative bacilli are rod-shaped bacteria that do not retain the crystal violet stain during Gram staining, making them a distinct category. They are characterized by a thin peptidoglycan layer and an outer membrane, often linked to various infections, including urinary tract infections (UTIs). This group includes important pathogens such as Pseudomonas aeruginosa and Salmonella typhi, known for their antibiotic resistance and association with severe infections. Gram-negative bacilli play a significant role in healthcare-related infections today.

The concept of Gram-negative bacilli in scientific sources
Gram-negative bacilli are rod-shaped bacteria, not retaining crystal violet stain, commonly implicated in urinary tract infections, particularly Escherichia coli, and characterized by their thin peptidoglycan layer and unique susceptibility patterns.
(1) These were the most common bacteria causing DFI, with Enterobacter spp. being the most dominant, as confirmed by the present study.[1] (2) These are types of bacteria that commonly cause nosocomial infections in the NICU, and are a frequent cause of infection.[2] (3) These are a type of bacteria, specifically non-fermentative ones, that were the subject of antimicrobial testing within the SENTRY program.[3] (4) These are a type of bacteria that are found in the initial blood flow, and can contribute to the bacterial contamination of blood products.[4] (5) This refers to another type of bacteria, Chryseobacterium meningosepticum, found in some CSF cultures that indicate infection.[5]
