Infection is
diagnosed when a laboratory identifies
Shigella in the stool (poop) of an ill person. The test could be a culture that isolates the bacteria or a rapid diagnostic test that detects genetic material of the bacteria.

Is Shigella Gram positive or negative?
Shigellae are
Gram-negative

than elsewhere. Shigella sonnei has been implicated in more foodborne outbreaks in developed countries than any other species. Outbreaks have been most often associated with food, water, and child care centers.
Is Shigella a virus or bacteria?
Shigella bacteria
cause an infection called shigellosis. Most people with Shigella infection have diarrhea (sometimes bloody), fever, and stomach cramps. Symptoms usually begin 1–2 days after infection and last 7 days. Most people recover without needing antibiotics.
Is Shigella VP positive?
Escherichia coli and Shigella dysenteriae are
citrate negative
.
Is Shigella an E coli?
Shigella causes bacillary dysentery and is classified into four species based on their antigen characteristics. This classification does not reflect genetic relatedness; in fact, Shigella species are
so related to Escherichia coli
, they should be classified as one distinctive species in the genus Escherichia.
What animals carry Shigella?
Salads (potato, tuna, shrimp, macaroni, and chicken)
, raw vegetables, milk and dairy products, and poultry can carry Shigella bacteria. Water contaminated with human waste and unsanitary handling by food handlers are the most common causes of contamination in these food products.
