What lab test would differentiate shigella flexneri from yersinia pseudotuberculosis?
To differentiate Shigella flexneri from Yersinia pseudotuberculosis, a key lab test is the urease test. Yersinia pseudotuberculosis is urease positive, while Shigella flexneri is urease negative. Additionally, biochemical tests such as the fermentation of lactose can help, as Shigella flexneri does not ferment lactose, whereas Yersinia may show variable lactose fermentation.

What is Salmonella shigella yersinia and serratia?
Salmonella, Shigella, Yersinia, and Serratia are all gram-negative facultatively anaerobic rods.
What sub-types of Yersinia are responsible for yersinosis?
Yersinia enterocolitica and Yersinia pseudotuberculosis are the sub-types responsible for causing yersinosis, a gastrointestinal illness. They are typically transmitted through contaminated food or water and can cause symptoms such as diarrhea, abdominal pain, and fever.
What do abnormal stool cultures show?
Shigella, Salmonella, Campylobacter, and Yersinia. Clostridium difficile produces a toxin that can cause severe diarrhea.
What are the most common bactyerial infections of the digestive tract?
The most common bacterial infections of the digestive tract are caused by Shigella, Salmonella, Campylobacter, and Yersinia. Patients taking certain antibiotics may be susceptible to infection with Clostridium difficile
What are some lactose negative oraganisms?
Lactose-negative organisms are those that do not ferment lactose and are often identified in microbiological studies. Examples include certain genera of bacteria such as Salmonella, Shigella, and Yersinia. These organisms can be significant in clinical diagnostics and food safety, as their inability to ferment lactose helps differentiate them from lactose-positive bacteria like Escherichia coli. Additionally, some strains of Proteus and Klebsiella may also exhibit lactose-negative characteristics.
What is a yersinia?
A yersinia is a bacterium of the genus Yersinia, which is an agent of several diseases, most notably bubonic plague.
What bacteria are non-lactose ferment er?
Mnemonic: KEE Klebsiella pneumoniae Enterobacter cloacae E. coli Shigella sonnei can ferment lactose, but only after prolonged incubation and so it is referred to as a '''''late-lactose fermenter'''''. Vibrio cholerae is also a late lactose fermenter.
Does Yersinia Pestis have a mitochondria?
No. Yersinia Pestis is a bacterium and so is a prokaryote. Prokaryotes do not have such organelles.
What is bacterium an example of?
Yersinia pestis, AKA, Bubonic Plague
What type of microorganism is plague?
The bubonic plague is a form of Yersinia pestis. Y. pestis is a bacterium that is facultative and anaerobic. Other forms of Y. pestis include the pneumonic and septicemic plagues.
List selective media for stool culture?
MacConkey agar: Selective for Gram-negative bacteria, inhibits the growth of Gram-positive bacteria. Hektoen enteric agar: Selective for Gram-negative enteric pathogens, such as Salmonella and Shigella species. Thiosulfate-citrate-bile salts-sucrose (TCBS) agar: Selective for Vibrio species, especially Vibrio cholerae. Cefsulodin-irgasan-novobiocin (CIN) agar: Selective for Yersinia species.
What are the Causes of the plague?
fleas, rats, lice,boils and all sorts of disease
