Opisthorchiasis in fish — Which fish species are infected with opisthorchiasis

Opisthorchiasis is a serious disease that occurs after exposure to the human body of parasites. Causes the disease Fluke cat from a subspecies of flatworm. Infection occurs after eating undercooked (insufficiently cooked) fish. However opisthorchiasis in fish is not always, not all of it is infected by opisthorchiasis. In order to avoid this unpleasant disease, you should know which fish have opisthorchiasis and beware of its vectors.

Dangerous than the disease

The first symptoms are very similar with any infectious disease. No distinguishing features of it, describes exactly opisthorchiasis. This greatly complicates the timely diagnosis and rapid assistance to the sick. Lost time parasites use to damage the liver, biliary tract.
After getting into the human body of the larvae of the Fluke for a long time, the disease doesn't manifest itself. This latency period allows the patient does not even suspect yourself of parasites. Later appear the first signs that also indicate a particular disease. A doctor can diagnose bile stasis, inflammation of the liver. The patient complains of violation of the chair, heaviness after eating (and it occurs even after a light snack), unpleasant bloating, flatulence, sometimes pain near the right upper quadrant. The pain may be experienced differently dependent on the severity of the patient's condition. Most often it is dull, nagging pain, there may be attacks of severe pain. Palpation shows a significant increase in the liver. With such a clinical picture is the presence of opisthorchiasis does not show itself.

The most unpleasant in this disease is the occurrence of complications. Inflammation takes large area, the worms multiply rapidly, block a bile ducts. It causes severe pain. The waste products of the parasites into the blood, which leads to intoxication, the temperature rises, there is a weakness, deteriorating General condition of the patient. There may also be a very strong allergic reaction.

Often the body does not produce these same antibodies are not fighting the infection. Then the most effective is ultrasound or radiography of the abdomen.

How do you get

Why opisthorchiasis is so prevalent. Fluke larvae are adapted to survive in different conditions. They do not die nor freeze, nor at high temperatures.

Method of treatment

So as to diagnose opisthorchiasis is almost impossible, doctors are often faced with the dire state of the patient. The large number of parasites can lead to serious intoxication, which can often be removed only in case of hospitalization. Treatment is to support the liver, elimination of toxins, destroying parasites and aid the body during the recovery phase. To destroy the worms, to specific drugs.
