Shigellosis (Historically the disease usually referred to as Dysentery) is an infection of the intestines caused by Shigella bacteria. [1] [3] Symptoms generally start one to two days after exposure and include diarrhea, fever, abdominal pain, and feeling the need to pass stools even when the bowels are empty. [1]
Salmonella species can be found in the digestive tracts of humans and animals, especially reptiles. Salmonella on the skin of reptiles or amphibians can be passed to people who handle the animals. [39] Food and water can also be contaminated with the bacteria if they come in contact with the feces of infected people or animals. [40]
Cary–Blair transport medium is a solution used to preserve fecal clinical specimens and rectal swabs after collection. The medium was devised by Sylvia G. Cary and Eugene B. Blair in 1964, [1] who noted it allowed for longer-term recovery of Salmonella, Shigella, Vibrio, and Pasteurella than other transport media.
Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
Shigella is a genus of bacteria that is Gram negative, facultatively anaerobic, non–spore-forming, nonmotile, rod shaped, and is genetically nested within Escherichia. The genus is named after Kiyoshi Shiga, who discovered it in 1897. [1] Shigella causes disease in primates, but not in other mammals; it is the causative agent of human ...
Salmonella is a group of bacteria that can cause foodborne illness. It is commonly associated with undercooked meat and eggs; however, outbreaks have recently been linked to other foods, such as ...
For example, Shigella is a longstanding World Health Organization (WHO) target for vaccine development, and sharp declines in age-specific diarrhea/dysentery attack rates for this pathogen indicate that natural immunity does develop following exposure; thus, vaccination to prevent this disease should be feasible. The development of vaccines ...
EMB is a differential microbiological media, which inhibits the growth of Gram-positive bacteria and differentiates bacteria that ferment lactose (e.g., E. coli) from those that do not (e.g., Salmonella, Shigella). [2] Organisms that ferment lactose appear dark/black or green often with "nucleated colonies"—colonies with dark centers. [3]
