Pseudomonas oryzihabitans is a nonfermenting yellow-pigmented, gram-negative, rod-shaped bacterium that can cause sepsis, peritonitis, endophthalmitis, and bacteremia. [1] It is an opportunistic pathogen of humans and warm-blooded animals that is commonly found in several environmental sources, from soil to rice paddies.
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 that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic ) membrane and an outer ...
Pseudescherichia vulneris is a Gram-negative bacterial species. P. vulneris is a fermentative, oxidase-negative, motile rod, which holds characteristics of the family Enterobacteraceae. This bacterium can colonize in the respiratory tract, genital tract, stool, and urinary tract.
P. oryzihabitans can also be a human pathogen, although infections are rare. It can cause peritonitis, [6] endophthalmitis, [7] sepsis and bacteremia. Similar symptoms although also very rare can be seen by infections of P. luteola. [8] P. plecoglossicida is a fish pathogenic species, causing hemorrhagic ascites in the ayu (Plecoglossus ...
Gram-positive spore-forming (Clostridium spp.) and non-spore-forming bacilli (Actinomyces, Propionibacterium, Eubacterium, Lactobacillus and Bifidobacterium spp.); and 4. Gram-negative cocci (mainly Veillonella spp.). The frequency of isolation of anaerobic bacterial strains varies in different infectious sites. [3]
Bacteroides fragilis is an anaerobic, Gram-negative, pleomorphic to rod-shaped bacterium. It is part of the normal microbiota of the human colon and is generally commensal, [1] [2] but can cause infection if displaced into the bloodstream or surrounding tissue following surgery, disease, or trauma. [3]
Phocaeicola vulgatus, (formerly Bacteroides vulgatus), [1] is a mutualistic anaerobic Gram negative rod bacteria commonly found in the human gut microbiome and isolated from feces. [2] P. vulgatus has medical relevance and has been notable in scientific research due to its production of fatty acids , potential use as a probiotic , and ...
Aeromonas veronii is a Gram-negative, rod-shaped bacterium found in fresh water and in association with animals. [2] In humans A. veronii can cause diseases ranging from wound infections and diarrhea to sepsis in immunocompromised patients.
