Is Shigella Gram positive or negative?

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.
