Enterobacteriaceae
Enterobacteriaceae is a large family of Gram-negative bacteria that includes, along with many harmless symbionts, many of the more familiar pathogens, such as Salmonella, Escherichia coli, Yersinia pestis, Klebsiella and Shigella. Other disease-causing bacteria in this family include Proteus, Enterobacter, Serratia, and Citrobacter. This family is the only representative in the order Enterobacteriales of the class Gammaproteobacteria in the phylum Proteobacteria.
Characteristics[edit | edit source]
Enterobacteriaceae are Gram-negative bacteria, as defined by their staining pattern in the Gram stain test, which is used as a classification tool in microbiology. They are also facultatively anaerobic, which means they can grow in both oxygen-rich and oxygen-poor environments.
Pathogenesis[edit | edit source]
Members of the Enterobacteriaceae can cause a wide range of infections, though for most species these are uncommon. These include urinary tract infection, sepsis, pneumonia, traveller's diarrhea, and hospital-acquired infections.
Treatment[edit | edit source]
Treatment depends on the specific bacterium involved, and the site and severity of the infection. Antibiotics are a common treatment, though some Enterobacteriaceae have developed antibiotic resistance.
