Yes or no disease in swine streptococcus bacteria will spread to people? Problem to be understood

25/05/2010


Currently, with the appearance of disease in the streptococcus bacteria make people confused, worried because everyone thought that blue ear pig disease, the disease can spread to the streptococcus bacteria. Scientists think that this is not the correct way for blue ear pig disease and swine Streptococcus disease are two completely different diseases. Not every blue ear pig disease are infected with streptococcus bacteria and infect humans.

To understand this problem, need to distinguish between disease and blue ear disease Streptococcus:

Blue ear disease: This disease is caused by a virus disease in pigs as pigs have high mortality and disease spread in nature with symptoms of redness and fever, particularly heavy bleeding can cause bleeding in the ear edges turn green, in fact this is the disorders reproductive respiratory (PRRS). Point to note is the blue ear pig disease in pigs and only cause infection for pigs, not able to infect humans.

Streptococcus disease in the pig:
It is caused by bacteria called Streptococus suis causes. Patients can usually meningitis, myocarditis, pneumonia, arthritis, bleeding in the skin, causing miscarriage pig ears and killing of bacteria is usually present in the nose and throat of the pig does not usually cause disease. But while meeting some conditions (such as blue ear pig disease, for example), they can cause disease herd. Streptococcus suis is also found in wild boar, horses, goats, cattle dogs and cats and even birds.

Streptococcus pig disease could infect humans through scratches on the skin, on mucous membranes. When transmitted to humans, patients show signs of fever, hemorrhage, meningitis is exponential, high fever, coma.

Relationship between Streptococcus disease in pigs and disease occur in humans.
Previously, sporadic disease occurs in people (not in translation) in several parts of Asia, particularly in 2005 the World Health Organization official notification of these diseases are rampant in China. However, if considering the degree of danger of causing disease, the disease will not easily spread as the disease caused by a virus. Because pathogens are bacteria should be easy to put out more services and can be treated effectively with antibiotics. And now this disease is also confirmed no signs of spread from person to person.

Road transmission: the bacteria can enter the body through open wounds and the wounds by building in and through ingestion.

Do not get confused between the disease and blue ear disease Streptococcus:
Pursuant to the characteristics of mechanisms of transmission lines, pathogens showed disease in swine Streptococcus completely different from blue ear disease. Essentially this is two diseases separately. Two patients only relevance is the blue ear pig disease will be infected and sick if Streptococcus bacteria are available in the surrounding environment and animals susceptible to opportunistic infections such as human being HIV infection. When the blue ear pig disease, the animal's resistance to major multiples are more likely to develop infections accounting for different types of bacteria which can infect both bacteria Streptococus suis.

According to scientific reports, then in 1993-1994, 90% of pigs infected with the virus of Japan and 10% have clinical symptoms blue ear disease, in 2000, in Canada 80% of infected pig ears green. But in these countries do not have shift Streptococcus infection in humans at that time.

That is not any blue ear pig disease that will Streptococcus infection.

People with risk:
Based on transmission lines, these subjects are at risk of infectious people in direct contact with pigs and pork products from undercooked pork, such as the farmers , veterinary staff, who slaughter, carriage trade, the processing of pork products infected. The eating of pork products cooked disease did not spread the disease. According to the results verify the latest working group on disease Streptococcus in swine to infect humans (MARD), the majority of people with this disease are caused by eating more soup (a dish made from blood pig alive , not cooked), and those who live in slaughter pigs

Prevention: Prevention is for people who depend on the disease control on herd. It is necessary to strictly control the movement and slaughter pigs as to ensure pork supply sources are clean sources of disease.

To prevent their own initiative, people absolutely not dead pig slaughtering sick pigs; not do, eat pork processing and disease. While making and food processing from pork meat not handle life on their hands if there are any scratches (since the tape and gloves were not waterproof), which keep food clean and wash hands with soap after handling raw meat every time. Do not share equipment between raw meat and processed meat cooked to avoid infection between raw meat and cooked meat, the meat must be cooked to destroy the bacteria.

Regarding the cases of patients infected with swine streptococcus bacteria in hospital treatment. Experts said that these patients were from the local epidemic is on the pig. Patients with these manifestations: Meningitis latex alone, sepsis alone or in combination of both types. Cases Streptococcus pig disease can cause meningitis coordination between latex and septicemia, the patients expressed very serious, can lead to shock, bleeding under the skin of each major segment, leading to rapid coagulation, multiple organ failure and possibly death.

The signs that, when infected with streptococcus bacteria, the disease has manifested high fever, can get to 40-41 degrees C, accompanied by gastrointestinal manifestations are diarrhea, or more expression encephalitis syndrome, syndrome respiration, especially with the large array of bleeding under the skin necrosis. When there are signs on, the patient needs to hospital immediately for medical treatment in time. People with this disease is by eating the blue ear pig disease or undercooked food contaminated with Streptococcus in processing and preservation.

According to the Ministry of Health, this is not a new illness, previously seen and reported. But at the time of blue ear pig disease outbreak is severe, the infection of Streptococcus and there can be release to occur. To prevent this disease, it is best to make people drink boiled cooked, not absolute slaughter and consumption of pork has expressed sick, sick ..

How to recognize infected pork "blue ear" and Streptococcus
Identifying infected swine Streptococcus difficult to determine with the naked eye, right through to the laboratory diagnostic microbiology. However, people can rely on the symptoms of red skin, red meat than usual and organs should also avoid eating red meat whether any disease is a disease what. Consumers should also buy pork at reputable stores, has Quarantine paper and thoroughly cooked before eating.
