Avoid swimming until you have fully recovered. Wait to have sex (vaginal, anal, and oral) for one week after you no longer have diarrhea. Because Shigella germs may be in stool for several weeks, follow safe sex practices, or ideally avoid having sex, for several weeks after you or your partner have recovered.... read more ›

Shigella spread easily; it takes just a small number of bacteria to make someone ill. People with a Shigella infection can spread the infection to others for several weeks after their diarrhea ends. You can get infected by swallowing Shigella.... continue reading ›
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.... see more ›
Nonetheless, Shigella species are Gram-negative, facultatively anaerobic, nonsporulating, nonmotile rods in the family Enterobacteriaceae. They do not decarboxylate lysine or ferment lactose within 2 days.... see details ›
Shigella can be spread for as long as the organism is present in a person's stool. People can pass Shigella in their stool for up to four weeks (possibly longer in asymptomatic people). Certain antibiotics may shorten the length of time a person can shed the organism in their stool.... continue reading ›
Shigella, which is host-adapted to humans and nonhuman primates, is transmitted via the fecal–oral route, including through direct person-to-person or sexual contact or indirectly through contaminated food, water, or fomites. Because as few as 10 organisms can cause infection, shigellosis is easily transmitted.... see more ›
Contact precautions. Contact Precautions are intended to prevent transmission of infectious agents, including epidemiologically important microorganisms, which are spread by direct or indirect contact with the patient or the patient's environment as described in I.B. 3.... see more ›
Shigellosis is a nationally notifiable infectious disease and is tracked using the following surveillance tools. For information on treatment recommendations, visit the Healthcare Professionals page. Reports trends in foodborne infections and tracks the impact of food safety policies nationally.... see details ›
How is Shigella spread? Shigella is found in the intestinal tract of infected people, and is spread by eating or drinking food or water contaminated with the bacteria. It can also be spread by direct contact with feces (even with microscopic amounts) from an infected person.... continue reading ›
Because shigellosis is self-limiting, some authorities recommend withholding antibiotic therapy. When an effective antibiotic is given, clinical improvement is anticipated within 48 hours.... view details ›
Shigellae are phylogenetically E. coli that were later classified as separate species on the bases of biochemical characteristics and clinical relevance , . Biochemical characteristics and serotyping are usually used to identify the species. However, many isolates cannot be distinguished as either E.... view details ›
To confirm the diagnosis of shigellosis, doctors take a sample of stool and send it to a laboratory to grow (culture) and identify the bacteria. Bacteria are also tested to see which antibiotics are effective (a process called susceptibility testing.... see more ›
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.... read more ›
It is not spread through the air or by touching or kissing someone. You actually have to get those germs in the mouth and to your stomach before it causes problems.... see details ›
Shigella spread very easily when a person eats food or drinks water contaminated with poop from an infected person. Food prepared by someone infected with Shigella can become contaminated and make other people sick. Shigella outbreaks have been linked to contaminated foods prepared by sick food workers.... continue reading ›
Shigella can cause infection in all age groups. High-risk group include very young, elderly, and immunocompromised person. Shigella species is relatively resistant to acid in the stomach, and few organisms are required to cause the disease.  Once ingested, it multiplies in the small intestine and enters the colon.... continue reading ›
Shigella infection is diagnosed through testing of a stool sample. Because the symptoms of a Shigella infection are consistent with a fairly large number of potential illnesses, including most foodborne infections, a diagnosis must be confirmed by a laboratory test.... continue reading ›
Salmonella will not ferment lactose, but produce hydrogen sulfide (H2S) gas. The resulting bacterial colonies will appear colorless with black centers. Shigella do not ferment lactose or produce hydrogen sulfide gas, so the resulting colonies will be colorless.... see details ›
Shigella is a gram-negative intracellular bacterial pathogen that initiates infection by invading cells and causing intense inflammation in the colonic and rectal epithelium. A low infective dose, on the order of 10 to 100 organisms is sufficient to produce disease.... see more ›
Shigella are microbiologically characterized as gram-negative, non-spore-forming, nonmotile bacteria. Their cells are 0.4 to 0.6 μm (1 micrometre; 1 μm = 0.000039 inch) across by 1 to 3 μm long. S. dysenteriae, spread by contaminated water and food, causes the most severe disease because of its potent exotoxin, but S.... continue reading ›
