What are the symptoms of Yersinia?

Common symptoms in children are fever, abdominal pain, and diarrhea, which is often bloody. Symptoms typically develop 4 to 7 days after exposure and may last 1 to 3 weeks or longer. In older children and adults, right-sided abdominal pain and fever may be the predominant symptoms and may be confused with appendicitis.

What are the common symptoms of Yersinia enterocolitica infection?

Symptoms of Y enterocolitica infection typically include the following:

• Diarrhea – The most common clinical manifestation of this infection; diarrhea may be bloody in severe cases.
• Low-grade fever.
• Abdominal pain – May localize to the right lower quadrant.
• Vomiting – Present in approximately 15-40\% of cases.

How is Yersinia diagnosed?

Yersiniosis usually is diagnosed by detecting the organism in the stool of an infected person. Many laboratories do not routinely test for Yersinia, so it is important to notify laboratory personnel when yersiniosis is suspected so that special tests can be done.

What causes Yersinia?

Yersiniosis is an infection caused most often by eating raw or undercooked pork contaminated with Yersinia enterocolitica bacteria. CDC estimates Y. enterocolitica causes almost 117,000 illnesses, 640 hospitalizations, and 35 deaths in the United States every year.

What are the symptoms of campylobacteriosis?

Most people who become ill with campylobacteriosis get diarrhea (loose stool/poop) which may be bloody, cramping, abdominal pain, and fever within two to five days after exposure to the bacteria. Nausea (a feeling of sickness in the stomach) and vomiting may also occur. The illness typically lasts about one week.

What diseases are caused by Yersinia pestis?

Plague is caused by the bacteria Yersinia pestis, a zoonotic bacteria usually found in small mammals and their fleas. People infected with Y. pestis often develop symptoms after an incubation period of one to seven days. There are two main clinical forms of plague infection: bubonic and pneumonic.

What does Yersinia pseudotuberculosis cause?

Yersinia pseudotuberculosis is a Gram-negative bacterium that causes Far East scarlet-like fever in humans, who occasionally get infected zoonotically, most often through the food-borne route.

What causes campylobacteriosis?

Campylobacteriosis is an infection caused by bacteria of the genus Campylobacter. These bacteria live in the intestines of healthy birds, and raw poultry meat commonly has Campylobacter on it.

When do campylobacteriosis symptoms start?

People with Campylobacter infection usually have diarrhea (often bloody), fever, and stomach cramps. Nausea and vomiting may accompany the diarrhea. These symptoms usually start 2 to 5 days after the person ingests Campylobacter and last about one week.

Who is most at risk for Yersinia pestis?

Risk factors for plague include living in rural areas, near animals such as rodents, or in houses where sanitation is poor. People who deal frequently with animals, such as veterinaries, are at higher risk for infection with Yersinia pestis.

What are the complications at pseudotuberculosis and enteric Yersiniosis?

Complications of Y pseudotuberculosis infection may include intussusception, bacteremia, septic arthritis, and disseminated infection, especially in immunocompromises or iron-overloaded patients.

What is the main factor in pathogenesis of a pseudotuberculosis?

The enteropathogen, Yersinia pseudotuberculosis, requires a large inoculum to produce the disease. The primary virulence factor is a plasmid-encoded protein that causes increased invasiveness. Yersinia pseudotuberculosis survives intracellularly.

What is yersiniosis and what causes it?

Yersiniosis is an infection caused most often by eating raw or undercooked pork contaminated with Yersinia enterocolitica bacteria. CDC estimates Y. enterocolitica causes almost 117,000 illnesses, 640 hospitalizations, and 35 deaths in the United States every year.

What are the symptoms of Yersinia pneumoniae?

Persons infected with Yersinia can have a variety of symptoms depending on the age of the person infected. Complications such as skin rash, joint pains or spread of bacteria to the blood stream can occur in a small number of cases.

Can Yersinia live in humans?

Yersinia can live in the intestines of animals including pigs, cows, sheep, horses, dogs, cats, rodents and birds as well as humans. When animals are slaughtered and butchered for food, bacteria from an animal’s intestines may contaminate the meat that we consume.

How do you test for Yersinia infection?

The diagnosis is confirmed when Yersinia bacteria is found in a person’s stool (poop). A sample of the stool must be sent to a lab, which uses special methods to grow and identify the germ. Sometimes, Yersinia bacteria can also be found in the blood.
