What are the three types of Salmonella enterica?
Salmonella Paratyphi A, B, and C are quite different organisms. Although Salmonella Paratyphi A is in a different serogroup than Salmonella Typhi, because of a minor difference in lipopolysaccharide sugars, they are genetically very closely related.
Is Salmonella enterica bacterial?
Salmonellae form a complex group of bacteria consisting of two species and six subspecies and include more than 2,579 serovars [1, 2]. Two species are currently recognized in the genus Salmonella, S. enterica and S. bongori [3].

What is the name of the infection caused by Salmonella enterica?
What illness do people get from Salmonella infection? Most types of Salmonella cause an illness called salmonellosis, which is the focus of this website. Some other types of Salmonella cause typhoid fever or paratyphoid fever.
What are the characteristics of Salmonella enterica?
Salmonella enterica is a facultative anaerobe and is a gram negative, motile and non-sporing rod that is 0.7-1.5 by 2.0-5.0 µm in size (4-6). PATHOGENICITY/TOXICITY: Salmonella enterica can cause four different clinical manifestations: gastroenteritis, bacteremia, enteric fever, and an asymptomatic carrier state (7).
What is Salmonella structure?
Structure, Classification, and Antigenic Types Salmonella species are Gram-negative, flagellated facultatively anaerobic bacilli characterized by O, H, and Vi antigens. There are over 1800 known serovars which current classification considers to be separate species.
Where is Salmonella enterica usually found?
SOURCES/SPECIMENS: All Salmonella enterica subspecies (with the exception of serotype Typhi) are found in blood, urine, feces, food and feed and environmental materials (14). Serotype Typhi is found in blood, urine, feces and bile (14).
What type of cell is Salmonella?
prokaryotic rods
Salmonella are a group of Gram-negative, nonspore forming prokaryotic rods. They are motile through the use of multiple flagella, but can switch to be nonmotile in culture.
What is Salmonella microbiology?
Microbiology. The Salmonella are gram-negative, facultative anaerobic, noncapsulated (except S. typhi/paratyphi), non-spore-forming, motile rods. They possess a 4.8 Mb genome, variably modified by multiple lysogenic phage genomes, plasmids, and other mobile genetic elements.
What are characteristics of Salmonella?
The disease Salmonellosis is a disease caused by the bacteria Salmonella. It is usually characterized by acute onset of fever, abdominal pain, diarrhoea, nausea and sometimes vomiting. The onset of disease symptoms occurs 6–72 hours (usually 12–36 hours) after ingestion of Salmonella, and illness lasts 2–7 days.
How was Salmonella enterica discovered?
Salmonella was first discovered and isolated from the intestines of pigs infected with classical swine fever, by Theobald Smith in 1855. The bacterial strain was named after Dr Daniel Elmer Salmon, an American pathologist who worked with Smith. The nomenclature of Salmonella is controversial and still evolving.
What are the types of Salmonella?
The two species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,600 serotypes.
What antibiotic is used for Salmonella?
Common first-line oral antibiotics for susceptible Salmonella infections are fluoroquinolones (for adults) and azithromycin (for children). Ceftriaxone is an alternative first-line treatment agent.
What are 4 Symptoms of Salmonella?
Key points about salmonella infections
- Salmonella infections are diarrheal infections caused by the bacteria salmonella.
- Symptoms of a salmonella infection may include diarrhea, fever, abdominal cramps 12 to 72 hours after infection chills, headache, nausea, or vomiting.
Is Salmonella a virus or bacteria?
Salmonellosis is an infection with a bacteria called Salmonella, Salmonella live in the intestinal tracts of animals, including birds. Salmonella are usually transmitted to humans by eating foods contaminated with animal feces.
