    Gram-negative bacteria are a diverse group of microorganisms that have a unique cell wall structure. These bacteria are characterized by their response to a laboratory staining technique called the Gram stain, which helps to classify them based on their cell wall composition. Gram-negative bacteria include many well-known pathogens such as Escherichia coli, Salmonella, Pseudomonas aeruginosa, and Neisseria gonorrhoeae. These bacteria can cause a wide range of infections in humans and animals, including urinary tract infections, pneumonia, meningitis, and gastrointestinal illnesses. Gram-negative bacteria are often more resistant to antibiotics compared to Gram-positive bacteria due to their outer membrane structure, which can make treatment more challenging. Understanding the characteristics of Gram-negative bacteria is important for diagnosing and treating infections caused by these microorganisms.
