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.
Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Cultures are found in soil, water, sewage, feces and gut environments.
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]
Infections caused by C. koseri can lead to various symptoms, including fever, chills, diarrhea, and abdominal pain. In severe cases, the bacterium can cause sepsis, meningitis, or brain abscesses. Brain abscesses have a high rate of mortality and complications, particularly in neonates.
These yield the bacteria causing the infection in 36% of cases, [12] usually after 24–48 hours of incubation. Bile, too, may be sent for culture during ERCP (see below). The most common bacteria linked to ascending cholangitis are gram-negative bacilli: Escherichia coli (25–50%), Klebsiella (15–20%) and Enterobacter (5–10%).
However, infection of pet animals is associated with diarrhea. [5] Further, human infections have been substantiated, with conclusive reports from Italy. The majority of these cases are among children less than 3 years old, who are more prone to oral contact with animal droppings. Symptoms are typified by diarrhoea with fever and acute ...
Pantoea agglomerans is a Gram-negative bacterium that belongs to the family Erwiniaceae.. It was formerly called Enterobacter agglomerans, or Erwinia herbicola and is a ubiquitous bacterium commonly isolated from plant surfaces, seeds, fruit, and animal or human feces and can be found throughout a honeybee's environment. [1]
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.
