The urinary and respiratory tracts are the most common sites of infection. The genus Enterobacter is a member of the coliform group of bacteria. It does not belong to the fecal coliforms (or thermotolerant coliforms) group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts.
Patients in whom bacteremia develops are typically immunocompromised, diabetic, or elderly, or have at least one serious underlying disease. [ citation needed ] M. morganii has been regarded as a normally harmless opportunistic pathogen, but some strains carry " antibiotic-resistant plasmids " and have been associated with nosocomial outbreaks ...
Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, [2] [3] is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places, a phenomenon known as xerotolerance. C. sakazakii utilizes a number of genes to survive desiccation [4] and this xerotolerance may be strain specific. [5]
Infection usually occurs when a person ingests foods that contain a high concentration [clarification needed] of the bacteria. Infants and young children are much more susceptible to infection, easily achieved by ingesting a small number [clarification needed] of bacteria. In infants, infection through inhalation of bacteria-laden dust is possible.
Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3] Capable of motility via peritrichous flagella, [4] it is approximately one to three microns in length.
Children under the age of five years, the elderly, and immunosuppressed adults are at an increased risk of systemic dissemination of the disease and need specialized treatment to combat the disease. Drinking extra fluids and antibiotics such as fluoroquinolones are typical treatments. [ 13 ]
Campylobacter jejuni is one of the most common sources of infectious enteritis, and the most common bacterial pathogen found in two-year-old and smaller children with diarrhoea. [12] It has been linked to consumption of contaminated water and food, most commonly poultry and milk.
Pinworm infection (threadworm infection in the UK), also known as enterobiasis, is a human parasitic disease caused by the pinworm, Enterobius vermicularis. [3] The most common symptom is pruritus ani, or itching in the anal area. [1] The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks. [2]
