The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
E. coli is a gram-negative, facultative anaerobe, nonsporulating coliform bacterium. [18] Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3. [19] [20] [21] E. coli stains gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane.
Actinomyces is a genus of the Actinomycetia class of bacteria.They all are Gram-positive and facultatively anaerobic, growing best under anaerobic conditions. [2] Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3]
Approximately 1% of the human population lacks this receptor, [citation needed] and its presence or absence dictates an individual's susceptibility or non-susceptibility, respectively, to E. coli urinary tract infections. Uropathogenic E. coli produce alpha- and beta-hemolysins, which cause lysis of urinary tract cells. [citation needed]
While many Escherichia are commensal members of the gut microbiota, certain strains of some species, most notably the pathogenic serotypes of E. coli, are human pathogens, [7] and are the most common cause of urinary tract infections, [8] significant sources of gastrointestinal disease, ranging from simple diarrhea to dysentery-like conditions, [3] as well as a wide range of other pathogenic ...
The opportunistic pathogen can cause hospitalized patients to have infections in the lungs (as pneumonia), blood, urinary tract, and in other body regions after surgery. [6] S. aureus is a Gram-positive, cocci-shaped bacterium, residing in the environment and on the skin and nose of many healthy individuals. [7]
Bacterial pneumonia is a bacterial infection of the lungs. Urinary tract infection is predominantly caused by bacteria. Symptoms include the strong and frequent sensation or urge to urinate, pain during urination, and urine that is cloudy. [14] The most frequent cause is Escherichia coli.
