Gram-negative bacteria are seen less frequently: Haemophilus influenzae , Klebsiella pneumoniae , Escherichia coli , Pseudomonas aeruginosa , Bordetella pertussis, and Moraxella catarrhalis are the most common. These bacteria often live in the gut and enter the lungs when contents of the gut (such as vomit or faeces) are inhaled.
In a specific study, stainless steel was inoculated with 10 7 CFU/cm 2 E. coli and K. pneumoniae, containing bla CTX-M-15 and bla NDM-1 (antibiotic-resistant genes) respectively. Thirty days later (at room temperature, 22˚ C), 10 4 viable cells remained; and, after 100 days, 100 CFU/cm 2 of E. coli remained. [63]
The most frequent cause is Escherichia coli. Urine is typically sterile but contains a variety of salts and waste products. Bacteria can ascend into the bladder or kidney and causing cystitis and nephritis. [15] [16] Bacterial gastroenteritis is caused by enteric, pathogenic bacteria.
The adjectives gram-positive and gram-negative derive from the surname of Hans Christian Gram, a Danish bacteriologist; as eponymous adjectives, their initial letter can be either capital G or lower-case g, depending on which style guide (e.g., that of the CDC), if any, governs the document being written.

Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. [9] Some strains have been associated with urinary tract and respiratory tract infections in immunocompromised individuals.
E. coli (EIEC) found only in humans Bloody or nonbloody EIEC infection causes a syndrome that is identical to shigellosis, with profuse diarrhea and high fever. Enterohemorrhagic E. coli (EHEC) found in humans, cattle, and goats Bloody or nonbloody The most infamous member of this pathotype is strain O157:H7, which causes bloody diarrhea and no ...
Enteric gram-negative bacteria, such as Escherichia coli and Klebsiella pneumoniae, are a group of bacteria that typically live in the large intestine; contamination of food and water by these bacteria can result in outbreaks of pneumonia. Pseudomonas aeruginosa, an uncommon cause of CAP, is a difficult bacteria to treat.
In patients with an early onset pneumonia (within 5 days of hospitalization), they are usually due to anti microbial-sensitive bacteria such as Enterobacter spp, E. coli, Klebsiella spp, Proteus spp, Serratia mare scans, community pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, and methicillin-sensitive S. aureus should also ...
