Description |
| Escherichia |
37 |
|
Escherichia, a genus of gram-negative rod-shaped bacteria, belongs to the family Enterobacteriaceae.
Escherichia coli has become a model organism for studying many of life's essential processes partly due to
its rapid growth rate and simple nutritional requirements.
Normally E. coli serves a useful function in the body by suppressing the growth of harmful bacterial species
and by synthesizing appreciable amounts of vitamins.
A minority of E. coli strains are capable of causing human illness by several different mechanisms.
E. coli serotype O157:H7 is a rare variety of E. coli that produces large quantities of one or more related, potent
toxins that cause severe damage to the lining of the intestine.

| Salmonella |
29 |
|
Salmonella is a genus of rod-shaped, gram-negative bacteria in the family
Enterobacteriaceae. This genus has two species: S. enterica, which is subdivided into over 2,000 serovars, and S. bongori.
Some serovars of S. enterica, such as S. typhi, cause systemic infections and typhoid fever.
Others, like S. typhimurium, cause gastroenteritis.
|
| Shigella |
9 |
|
Shigella is a group of gram-negative, facultative intracellular pathogens in the family
Enterobacteriaceae. Recognized as the etiologic agents of bacillary dysentery
or shigellosis in the 1890s, Shigella was adopted as a genus in the 1950s and subgrouped into four
species: S. dysenteriae, S. flexneri, S.boydii and S. sonnei(also designated as serogroups A to D).
|
| Yersinia |
25 |
|
Yersinia, a gram-negative rod-shaped bacterium, is a genus of bacteria in the family
Enterobacteriaceae. Yersinia pestis, the causative agent of plague, whose most common clinical form
is acute febrile lymphadenitis, is more commonly known as bubonic plague.
Other members of the genus, Y. entercolitica and Y. pseudotuberculosis, are also human pahtogens.
|
| Citrobacter |
1 |
|
Citrobacter is a genus of gram-negative coliform bacteria in the
Enterobacteriaceae family and the phylum Proteobacteria. Three members of
the genus, C. amalonaticus, C. diversus and C. freundii are linked to human disease
with C. diversus linked to frequent nosocomial outbreaks of neonatal meningitis.
|
| Cronobacter |
1 |
|
Cronobacter, a genus of gram-negative, rod-shaped bacteria in the family
Enterobacteriaceae and the phylum Proteobacteria, is recognised as causative
agents of neonatal bacteraemia, meningitis and necrotising enterocolitis.
|
| Enterobacter |
1 |
|
Some members of the genus Enterobacter are important nosocomial pathogens.
Several strains of these gram-negative rod-shaped bacteria in the family Enterobacteriaceae
cause opportunistic infections in immunocompromised patients.
Two clinically-important species from this genus are E. aerogenes and E. cloacae.
|
| Erwinia |
2 |
|
Current members of the genus Erwinia are primarily pathogens of plants.
They are gram-negative rod-shaped bacteria in the family Enterobacteriaceae.
The genus was named for the first phytobacteriologist, Erwin Smith.
|
| Klebsiella |
2 |
|
Klebsiella is a genus of non-motile, gram-negative, rod shaped bacteria in
the family Enterobacteriaceae with a prominent polysaccharide-based capsule.
Three species in the genus Klebsiella are associated with illness in humans:
K. pneumoniae is a primary pathogen capable of causing urinary tract infections and pneumonia in otherwise
healthy people, K. oxytoca can cause a variety of nosocomial infections,
and K. granulomatis causes chronic genital ulcerative disease.
|
| Pectobacterium |
1 |
|
Pectobacterium are gram-negative rod-shaped bacterium in the family Enterobacteriaceae that are pathogens of angiosperms
with a broad host range. Pectobacterium carotovorum (syn Erwinia carotovora) is a plant pathogen able to cause disease
in almost any plant tissue it invades.
|
| Photorhabdus |
1 |
|
Photorhabdus is a gram-negative member of the family Enterobacteriaceae that
lives in a mutualistic association with a Heterorhabditis nematode worm.
The nematode worm burrows into insect prey and regurgitates Photorhabdus,
which goes on to kill the insect. Once the insect host is dead the bacteria
bioconvert the tissues into more bacteria. The nematode feeds off the growing
bacteria until the insect tissues are exhausted, whereupon they reassociate
and leave the cadaver in search of new prey. This highly efficient
partnership has been used for many years as a biological crop protection
agent. In addition to its well-described role as an insect pathogen one
species of the genus, P. asymbiotica, causes infection in otherwise healthy humans.
|
| Proteus |
1 |
|
Proteus is a gram-negative member of the family Enterobacteriaceae.
Several species in this genus are opportunistic human pathogens. Most prominent is P. mirabilis which causes wound and
urinary tract infections. Another species, P. vulgaris, can cause urinary tract and wound
infections and is a common cause of sinus and respiratory infections.
|
| Serratia |
1 |
|
Serratia is a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria of
the Enterobacteriaceae family. Serratia marcescens is the primary pathogenic species and is commonly found in the
respiratory and urinary tracts of hospitalized adults and in the gastrointestinal system of children. Rare reports have described disease
resulting from infection with S. plymuthica, S.liquefaciens, S. rubidaea, S. odorifera and S. fonticola.
