Furthermore, from the evolutionary point of view, the members of genus Shigella (dysenteriae, flexneri, boydii, sonnei) are actually E. coli strains "in disguise" (i.e. (wikipedia.org)
The unknown bacteria will be one of the following: Enterococcus faecalis, Staphylococcus saprophyticus, Escherichia coli, Enterobacter aerogenes, Proteus vulgaris, Salmonella [I assume typhimurium], or Shigella [either flexneri or sonnei, we used both in our lab during the semester]. (acasestudy.com)

Shigella dysenteriae belongs to the genus Shigella, which consists of four species: S. sonnei, S. flexneri, S. boydii, and S. dysenteriae. (stemcelldaily.com)
Shigella flexneri was the most common Shigella species isolated and 73% to 95% of these isolates were resistant to ampicillin, trimethoprim-sulfamethoxazole, chloramphenicol and tetracycline but remain susceptible to nalidixic acid, ciprofloxacin, and ceftriaxone. (biomedcentral.com)
was isolated which includes 12 S. flexneri and 3 S. sonnei . (biomedcentral.com)
Escherichia14
Escherichia coli is one of the most diverse bacterial species, with several pathogenic strains with different symptoms and with only 20% of the genome common to all strains. (wikipedia.org)
Following a revision of Bacteria it was reclassified as Bacillus coli by Migula in 1895 and later reclassified as Escherichia coli. (wikipedia.org)
however, bacteria were considered primitive and pre-cellular and received little attention before 1944, when Avery, Macleod and McCarty demonstrated that DNA was the genetic material using Salmonella typhimurium, following which Escherichia coli was used for linkage mapping studies. (wikipedia.org)
An extensive list of Escherichia coli K-12 strain derivatives and their individual construction, genotypes, phenotypes, plasmids and phage information can be viewed at Ecoliwiki. (wikipedia.org)
There is only one bacteria on the list for which we saw a positive result in our regular lab sessions for MR-VP - Escherichia coli. (acasestudy.com)
I am redoing this test because most of the remaining bacteria species are catalase-negative - except for Escherichia coli, which I am sure is catalase positive. (acasestudy.com)
In vitro study was found that the extract was comparable to that of ciprofloxacin and mostly active against the strains of Vibrio cholerae, followed by Escherichia coli (E. coli) and Shigella spp. (sarkarhomoeo.com)
Shigellae are Gram-negative, non-motile, facultative anaerobic pathogens that are closely related to Escherichia coli but have evolved specific traits of pathogenicity, physiology and serology (Ud-Din and Wahid, 2014). (thisisbeep.com)
The Shigella genus is part of the larger Enterobacteriaceae family and, in fact, many researchers have suggested that Shigella and Escherichia should be considered one genus. (thisisbeep.com)
Shigella are differentiated from the closely related Escherichia coli on the basis of pathogenicity, physiology (failure to ferment lactose or decarboxylate lysine) and serology. (thisisbeep.com)
They are closely related to Escherichia coli (E. coli) but differ in their ability to invade and replicate in the cells lining the colon. (stemcelldaily.com)

The 5% lactose fermentation test in parallel is suggested when the O.N.P.G. test is used for isolating routine pathogens, because organisms such as Shigella sonnei, Shigella dysenteriae 1, and Pasteurella pseudotuberculosis are O.N.P.G. positive. (thisisbeep.com)
Shigella species are facultative anaerobes, are non-motile, oxidase negative, urease negative, do not decarboxylate lysine, and all except S. dysenteriae type 1 are catalase positive1. (thisisbeep.com)
Shigella dysenteriae is a type of bacteria that causes a severe form of intestinal infection called shigellosis or bacillary dysentery. (stemcelldaily.com)
Shigella dysenteriae is the most virulent species of Shigella and can cause outbreaks of epidemic dysentery in developing countries with poor sanitation and hygiene. (stemcelldaily.com)
Shigella dysenteriae is transmitted by the fecal-oral route, meaning that it can spread through contaminated food, water, surfaces, or direct contact with infected people or animals. (stemcelldaily.com)
Shigella dysenteriae infection can be diagnosed by isolating and identifying the bacteria from stool samples using culture methods or molecular techniques. (stemcelldaily.com)
However, antibiotic resistance is a growing problem among Shigella species, especially S. dysenteriae type 1, which can be resistant to multiple classes of antibiotics. (stemcelldaily.com)
Therefore, prevention measures such as improving sanitation and hygiene, providing safe water and food, and promoting handwashing are essential to control the spread of Shigella dysenteriae infection. (stemcelldaily.com)
Shigella dysenteriae is a gram-negative, rod-shaped bacterium that causes shigellosis, a severe form of bacillary dysentery. (stemcelldaily.com)
Shigella dysenteriae belongs to the family Enterobacteriaceae and has four serogroups: A, B, C, and D. Serogroup A contains the most virulent strain, S. dysenteriae type 1, which is responsible for most outbreaks of shigellosis worldwide. (stemcelldaily.com)
Shigella dysenteriae causes disease by invading and replicating the cells lining the colon. (stemcelldaily.com)
Adherence: Shigella dysenteriae uses structural gene proteins called invasion plasmid antigens (Ipa) to attach to the surface of epithelial cells and M cells (specialized cells that transport antigens across the intestinal mucosa). (stemcelldaily.com)
Invasion: Shigella dysenteriae uses a type III secretion system (T3SS) to inject four Ipa proteins (IpaA, IpaB, IpaC, IpaD) into the cytoplasm of the target cells. (stemcelldaily.com)
Once inside the vacuole, Shigella dysenteriae escapes by lysing the vacuolar membrane with another protein called IcsA (intracellular spread antigen). (stemcelldaily.com)
Shigella dysenteriae can also evade the host immune system by hiding inside the host cells and avoiding exposure to antibodies and complement. (stemcelldaily.com)
In 1885, Theodor Escherich, a German pediatrician, first discovered this species in the feces of healthy individuals and called it Bacterium coli commune because it is found in the colon and early classifications of Prokaryotes placed these in a handful of genera based on their shape and motility (at that time Ernst Haeckel's classification of Bacteria in the kingdom Monera was in place). (wikipedia.org)

Strains7
Four of the many E. coli strains (K-12, B, C, and W) are thought of as model organism strains. (wikipedia.org)
Due to the lack of specific record-keeping, the "pedigree" of strains was not available and had to be inferred by consulting lab-book and records in order to set up the E. coli Genetic Stock Centre at Yale by Barbara Bachmann. (wikipedia.org)
The different strains have been derived through treating E. coli K-12 with agents such as nitrogen mustard, ultra-violet radiation, X-ray etc. (wikipedia.org)
The original E. coli B strain, known then as Bacillus coli, originated from Félix d'Herelle from the Institut Pasteur in Paris around 1918 who studied bacteriophages, who claimed that it originated from Collection of the Institut Pasteur, but no strains of that period exist. (wikipedia.org)
We also encountered six exceptional strains which showed positive H2S production among S. sonnei strains isolated in 1964. (thisisbeep.com)
