- Gram-negative anaerobic bacteria, such as Bacteroides spp., Porphyromonas spp., Prevotella spp., and Fusobacterium spp., are normally innocuous and even protective components of the human microbiota. If, however, they escape from the site they normally colonize, they can cause serious infections ranging from abscesses to bacteremia.

Mar 13, 2024 · Anaerobic bacteria are the predominant cultivable and noncultivable bacteria in the human body and can be recovered from infections at virtually all anatomic sites, although the frequency of recovery is highly variable.

Anaerobic Gram-negative bacilli are common elements of the mucous membrane flora throughout the body; they often act as secondary pathogens. They are the most common anaerobes involved in infection and include some of the most antibiotic-resistant species.

Gram-negative anaerobes and some of the infections they cause include. Bacteroides (most common): Intra-abdominal infections. Fusobacterium: Abscesses, wound infections, and pulmonary and intracranial infections. Porphyromonas: Aspiration pneumonia and periodontitis. Prevotella: Intra-abdominal, dental, gynecologic, and soft-tissue infections.
Gram-negative bacteria can cause various infections, such as gastroenteritis, pneumonia, peritonitis (inflammation of the membrane that lines the abdominal cavity), urinary tract infections, bloodstream infections, wound or surgical site infections, and meningitis. Many infections can be serious.

Aug 8, 2023 · Objectives: Outline the types of gram-negative organisms that are clinically significant. Identify the treatment options for gram-negative infections based on the location and type of infection. Describe the mechanisms by which gram-negative bacteria can become resistant to antibiotics.
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1] Their defining characteristic is their cell envelope , which consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic ) membrane and an ...
