How is Yersinia pseudotuberculosis transmitted?
Pseudotuberculosis, caused by Yersinia pseudotuberculosis, is a zoonosis which can be transmitted to man through skin contact with infected animals, contaminated water, or by the consumption of contaminated food or vegetables.
How is Yersinia spread?
How is yersiniosis spread? Yersinia bacteria are spread by eating or drinking contaminated food or water or by contact with an infected person or animal.
How do you get Yersinia bacteria?
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.
Where is Yersinia pseudotuberculosis found?
Pathogenesis. In animals, Y. pseudotuberculosis can cause tuberculosis-like symptoms, including localized tissue necrosis and granulomas in the spleen, liver, and lymph nodes.
How can Yersinia pseudotuberculosis be prevented?
Prevention of Y pseudotuberculosis infection is best accomplished by appropriate handling of pork and wild animal intestines, particularly during preparation of food that might be stored in cold temperatures.
How long Yersinia live on surfaces?
Previous studies evaluating viability of Y. pestis on manufactured surfaces (e.g., steel, glass) have shown that survival is typically <72 hours (18).
Where can Yersinia be found?
enterocolitica is found in wild and domestic animals, especially pigs. It can also be found in birds, reptiles, rodents, rabbits, sheep, cattle, horses, dogs, and cats. People can become infected with Y.
How can you prevent Yersinia?
Avoid eating raw or undercooked pork. Thoroughly cook raw meat and poultry to destroy the bacteria. Meat, poultry, pork, and hamburgers should be cooked until they are no longer pink in the middle. Defrost food in the refrigerator, in cold water, or in the microwave.
Who is the main reservoir and source of pseudotuberculosis infection?
Animals are the major reservoir of Y pseudotuberculosis. This bacterium causes severe and, at times, lethal infections in susceptible animal species, in particular lagomorphs (hares and rabbits) during epizootics. In birds and rodents, Y pseudotuberculosis produces mild or asymptomatic infection.
What disease is caused by Yersinia pseudotuberculosis?
Erythema nodosum, arthralgias, reactive arthritis, ankylosing spondylitis, and lumbar facet joint disease can occur. A sporotrichoid pattern of disease has been associated with Yersinia pseudotuberculosis infection.
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.
Can Yersinia come back?
Yersinia enterocolitica and Yersinia pseudotuberculosis are bacterial infections that are uncommon, but can cause problems when they occur. Y enterocolitica causes a condition called enterocolitis, which is an inflammation of the small intestine and colon that occurs, and often recurs, mostly in young children.
How long can Yersinia last?
How long does it last? The symptoms usually last for 1 to 3 weeks. People with mild symptoms usually recover on their own without treatment.
What are the main signs of the abdominal form of pseudotuberculosis?
[5] Symptoms include abdominal pain, fever, vomiting, and diarrhea. The abdominal pain is often located in the right lower quadrant and may mimic appendicitis. Other problems associated with Yersinia pseudotuberculosis infection include terminal ileitis and intussusception, more commonly in children.
Is Yersinia serious?
CDC estimates that infections with Yersinia enterocolitica cause almost 117,000 illnesses, 640 hospitalizations, and 35 deaths in the United States every year. Children are infected more often than adults, and the infection is more common in the winter.
