Cholera

It refers to especially dangerous acute infectious diseases and is characterized by a serious condition and dehydration of the body. The causative agent of cholera is cholera vibrio. It can for a long time remain viable in various environmental objects. In milk and dairy products, the causative agent of cholera persists for 14 days, in boiled water for up to 40 hours, in open water for up to several months, in soil for up to 2 months. The optimum growth temperature is 25-37 ° C. Dies when heated to 80 ° C after 5 minutes. Resistant to low temperatures. Vibrio cholerae forms potent poisons. The disease begins with sudden diarrhea, later vomiting joins, very strong.
The body loses up to 35 liters of fluid. Sharp disturbances of the water-salt balance of the body occur. Due to the large loss of water, the skin gathers in folds, convulsions are possible, severe thirst, shortness of breath are noted. Infection occurs through food and water contaminated with secretions that contain vibrios. Flies play a significant role in the spread of pathogens. Bacteria are usually not formed. Prevention consists in strict adherence to hygiene skills when using food products. The sanitary protection of water supply sources, the neutralization of sewage, and the destruction of flies are of great importance.

Cholera

  1. El Tor cholera (etiopathogenesis, clinical features of modern cholera)
    Etiology: vibrio El Tor. Pathogenesis: see question 22.1. Features of the course of modern cholera: 1) the possibility of prolonged vibrio-carriage and a high frequency of erased forms of the disease 2) greater resistance of the pathogen in the external environment compared to the classical version of cholera vibrio. Clinic: see question 22.1 (worn and light
  2. Cholera
    Cholera is an acute intestinal disease caused by Vibrio cholerae (serotype 01), which can produce enterotoxin. Manifestations of cholera range from asymptomatic to extremely severe forms, when a suddenly developing disease leads to hypovolemic shock, metabolic acidosis and, in untreated cases, to death. Etiology. The causative agent of cholera is short, slightly curved, mobile
  3. CHOLERA
    Cholera is an acute anthroponous intestinal infection caused by cholera vibrio and characterized by watery diarrhea followed by the addition of vomiting, the development of dehydration, demineralization and acidosis. HISTORY. Even before our era, the characteristic signs of this disease were described, rapid spread and high mortality were indicated. At the beginning of the 19th century, when
  4. Cholera
    Cholera is an acute infectious disease characterized by damage to the gastrointestinal tract and a violation of the water-electrolyte balance of the body. The disease is caused by vibrio - a special microorganism discovered in 1854 by the Italian pathologist F. Pacini in the intestines of the victims of cholera. In 1883, the famous German scientist and doctor R. Koch, who specifically worked in the outbreaks of the epidemic
  5. CHOLERA
    Charles C. J. Carpenter (Charles C. /. Carpenter) Definition. Cholera is an acute disease that occurs as a result of colonization of the small intestine with cholera vibrios. The disease is characterized by the epidemic spread and development in severe cases of massive diarrhea with a rapid loss of extracellular fluid and electrolytes. Etiology and epidemiology. Vibrio cholerae - curved
  6. Cholera
    Cholera is an acute infectious disease caused by a cholera vibrio that can produce enterotoxin. The causative agents of cholera are stable in the external environment. The source of infection is patients with typical and atypical forms of cholera that secrete cholera vibrios with feces into the environment. Of great danger are patients in the acute period of the disease, vibration carriers, as well as
  7. CHOLERA
    {foto7} Cholera (lat. cholera)? acute intestinal anthroponotic infection caused by bacteria of the species Vibrio cholerae. It is characterized by the fecal-oral mechanism of infection, damage to the small intestine, watery diarrhea, vomiting, the fastest loss of body fluid and electrolytes with the development of varying degrees of dehydration up to hypovolemic shock and death. "Classical" cholera
  8. Question 35. CHOLERA
    - An acute infectious disease characterized by toxic damage to the small intestine, the development of severe gastroenteritis, impaired water-electrolyte metabolism and dehydration. Belongs to especially dangerous infections. Etiology. The causative agents of cholera are two microorganisms: the cholera vibrio of Koch and the vibrio of El Tor. vibrios are divided into three serological types: Otava type
  9. Cholera
    Cholera is a disease caused by the entry of cholera bacteria into the small intestine. As a result of the action of these bacteria, intense diarrhea begins, which leads to dehydration and disrupts its ionic balance. See the article GUTTER (PROBLEMS), with the addition that a person should stop considering himself evil, intolerable,
  10. When should you suspect cholera?
    The presence of cholera should be suspected when a child older than 5 years or an adult develops severe dehydration due to acute watery diarrhea (usually accompanied by vomiting), or any other patient older than 2 years old with a diagnosis of acute watery diarrhea, if there is evidence of cholera diseases in this territory. Younger children may also experience
  11. Epidemiology of Cholera
    This is anthroponosis. The source of infection is only people. Groups of vibriocarriers: 1. Patients with a typical form of cholera, the maximum release of vibrios during the disease. The most dangerous severe form when there is severe enteritis and severe vomiting. 2. Patients with subclinical or erased form of cholera. The clinic is insignificant, but significant isolation of the pathogen and the spread of infection.
  12. ETHIOLOGICAL CHARACTERISTICS OF CHOLERA Causative
    There are two types of pathogens: the classic cholera vibrio (cholera biotype), and the cholera vibrio biotype El Tor. They differ in biochemical properties. Morphology: curved stick with a sufficiently long flagellum. Spore and capsules do not form. Gy (-), are well stained with aniline dyes. May form L-forms. Growth features: obligate aerobes, optimal environment - alkaline
  13. Cholera
    Cause The source of infection is a sick person or carrier. Infection can occur by water and contact-household, as well as through food. Symptoms Diarrhea, profuse vomiting, discharge from the intestines and vomit have the same composition, representing a yellow-green liquid, dehydration is observed. When examining a patient there is tachycardia, low blood pressure.
  14. Cholera (pasteurellosis)
    This is an acute infectious disease of all types of poultry, which is accompanied by intoxication of the body. Cholera is spread by sick and ill birds, infected care products, food, water and maintenance personnel. The causative agent of cholera is a stick, which at a temperature of 70 ° C dies within 30 minutes, and when boiled - instantly. The infection entry gates are
  15. CHOLERA
    Cholera is an acute intestinal infection caused by cholera vibrio, characterized by gastroenteric manifestations with rapid dehydration due to loss of fluid and electrolytes with vomit and stool. Clinical diagnosis The incubation period from several hours to 5 days. Light form. Weight loss - 3-5%. Moderate thirst and dryness
  16. Suspected cholera patient
    Cholera differs from acute diarrhea caused by other causes in three ways: • this disease occurs during mass epidemics when both children and adults become ill; • there may be profuse watery diarrhea, which in the shortest possible time causes severe dehydration against hypovolemic shock; • treatment of patients with severe dehydration with appropriate antibiotics
  17. Cholera.
    The causative agent is Vibrio cholerae. The transmission path is feck-op. Pathogenesis. Wozb does not have invasive sv. Using the O-a / gene - adhesion to receptors of the small intestine, colonization of the mucosa, production of enterotoxin - irreversible activation of adenylate cyclase - continuous secretion - dehydration. The incubation period is 2-3 days (up to 5 days). The clinical picture. It happens: 1) clinically
  18. Cholera
    - acute anthroponous intestinal infection with fecal-oral transmission mechanism. Diarrhea and vomiting are characteristic, leading to times of dehydration and demineralization. (quarantine infection) (O 1 - el tor; O 139 - Bengal) Movable Gr (-) sticks with a long flagellum. They love a slightly alkaline environment. Endotoxin (LPS complex) and exotoxin (enterotoxin, cholegen). Source: people especially in the early days
