Salmonellosis is an acute infectious disease caused by microbes of the genus Salmonella, occurring mainly with gastrointestinal tract lesions, less often in the form of generalized forms.
The incubation period with the alimentary route of infection is 12-24 hours, with a contact - 3-7 days.
Gastrointestinal form. Gastritis, enteritis, gastroenteritis. The onset is acute. Fever, epigastric pain, nausea, vomiting. Intoxication (headache, weakness, weakness, anorexia). The stool is liquid, watery, fetid, undigested, dark green in color. Exicosis.
Enterocolitis, gastroenterocolitis, colitis. The onset is acute. Fever, intoxication, nausea, persistent vomiting. epigastric pain. Enlarged liver and spleen. Spasm and soreness of the large intestine. There may be tenesmus. Liquid stool with an admixture of mucus, blood, dark green in the form of “swamp mud”. Prolonged severe toxicosis, less often exicosis, persistent intestinal dysfunction.
Typhoid-like form. The onset is acute. Fever, intoxication. The skin is pale, dry. Cyanosis. Muffling of heart sounds, bradycardia. Thickly coated and thickened tongue, flatulence, infrequent, but persistent vomiting, enlargement of the liver and spleen. Roseolous or roseolopapular rash. The chair is enteric or normal.
Septic form. It develops in newborns and debilitated children. Fever with large daily swings. The clinic depends on the localization of the purulent focus. Pneumonia, purulent meningitis, nephritis, hepatitis, arthritis, enterocolitis.
Nosocomial salmonellosis, especially in young children, is usually more difficult and prolonged, accompanied by significant intoxication and gastroenterocolitis. Toxicodystrophic conditions may develop. In children older than 3 years of age and adults, nosocomial salmonellosis can proceed easily.
1. The bacteriological method. From the first days of the disease, a triple (the first - before the start of etiotropic therapy) study of bowel movements is carried out in order to isolate the pathogen. Material for research can also be vomit, gastric lavage, food debris, if a generalized infection is suspected - blood (in the first days of the illness), urine (from the end of the 2nd week), cerebrospinal fluid, sputum. Primary seeding media are selenite (bile broth) or one of the differential diagnostic media for enterobacteria.
2. The serological method. Paired sera are examined in RA and RPHA (with an interval of 7-10 days) in order to detect antibodies and increase their titer.
3. Coprocytoscopy and sigmoidoscopy can judge the nature and localization of the inflammatory process in the intestine.
Activities for patients and contacts
Hospitalization. According to clinical and epidemiological indications.
Isolation contact. Not carried out. Set medical supervision for 7 days to detect recurrent diseases in the outbreak. Workers of food enterprises and persons equated with them, children attending nurseries, kindergartens, as well as orphanages and boarding schools undergo a single bacteriological examination of stool without removal from work and removal from the team.
With the simultaneous occurrence of the disease in several groups of a preschool institution, all children, group personnel, food service workers and all other personnel are examined bacteriologically.
The frequency of the examination is determined by the epidemiologist.
With nosocomial salmonellosis:
- the patient is isolated;
- in case of a group disease (outbreak), a temporary organization of a special department on the spot is possible;
- after removal of the patient hospitalization in this chamber stops
new patients within 7 days;
- contacts remain in the ward and undergo a single bacteriological examination and further clinical observation;
- if 3 or more cases of the disease occur in different rooms or when salmonella is sown from swabs or air in different rooms, the department is closed and all children, mothers and staff are examined.
Such a branch is opened after a complex of anti-epidemic measures is carried out with the permission of TsGSEN.
Statement conditions. Not earlier than 3 days after clinical recovery, normal temperature and stool; negative result of a single bacteriological examination of feces, conducted no earlier than 2 days after the end of etiotropic therapy.
Employees of food enterprises and persons equated with them, children under 2 years old and children attending preschool institutions are discharged under these conditions after a double negative bacteriological examination of the bowel movements.
Admission to the team. After clinical recovery, with the exception of employees of food enterprises and persons equated to them, and children of nurseries and orphanages. These persons are not allowed into the team within 15 days after being discharged from the hospital (they conduct a three-fold bacteriological examination of feces with an interval of 1-2 days). When the pathogen is isolated, the observation period is extended for another 15 days, etc.
Chronic carriers of salmonella are not allowed in nurseries and children's homes, and employees of food enterprises and persons equated with them are transferred to work not related to food.
Bacterial carriers-schoolchildren (including boarding schools) are not allowed on duty at the catering and dining room.
Clinical examination: Workers of food enterprises and persons equal to them, children under 2 years of age and organized preschoolers are observed for 3 months with a monthly study of bowel movements
Polyvalent salmonella bacteriophage is used for prophylactic purposes according to epidemiological indications to all persons who have interacted with patients or salmonella excretors.
Sanitary and veterinary supervision of slaughter of cattle and poultry. Compliance with the rules of storage and preparation of food products. Deratization.

Salmonellosis of birds (Latin, English - Salmonellosis; paratyphoid, infectious diarrhea of birds) is a disease characterized by an acute course of septicemia in young animals and latent infection in an adult bird. Historical background, distribution, hazard and damage. Salmonella is widespread. Salmonella was first isolated from pig organs by American veterinarians Salmon and Smith in 1885.
Salmonellosis (lat., English. - Salmonellosis; paratyphoid) - a large group of zoonotic diseases of mainly farm animals, characterized in young animals in acute course with fever, septicemia, toxicosis and diarrhea, and in subacute and chronic pneumonia and arthritis; in adult females, by abortion; in humans, it proceeds in the form of foodborne toxicoinfections (see color insert).
Salmonellosis (salmonellosis) is an infectious disease of birds, mainly young animals, characterized by diarrhea, conjunctivitis, septicemia, intestinal damage and exhaustion. Etiology. The causative agents of the disease S. typhimurium, S. enteritidis, S. сholeraesuis, short gram-negative, motile, spores and capsules not forming sticks.

- SALMONELLOSIS AND THEIR PREVENTION
According to the classification of foodborne diseases, salmonellosis was previously assigned to the group of microbial food poisoning that causes toxic infections. Currently, according to the current classification, salmonellosis is assigned to the group of acute intestinal infections, where they are allocated in an independent section: "Other salmonella intestinal toxicoinfections." However, in their appearance, course, prevention, they also

These are intestinal diseases caused by bacteria of the Salmonella genus (with the exception of Salmonella, which causes typhoid fever and paratyphoid fever), with severe symptoms of intoxication. These microorganisms are stable in the environment, tolerate low temperatures, survive in water and household items at room temperature for up to 45-90 days. In salted meat - 2-3 months, in milk - 2-40 days. At

Etiology. Salmonella are motile gram-negative bacteria that do not have capsules and do not form spores. The main antigens of Salmonella are flagellates (H), antigens of the cell wall (O) and
Salmonellosis is an acute infectious disease caused by Salmonella, most often Salmonella tyrhimurium. Cats are sick much less often than dogs, although epizootics also occur, especially in kittens (R.M. Gaskell, M. Bennet, 1999). Infection occurs alimentary by eating salmonella-contaminated foods or wild bird meat. As a contributing factor, immunosuppression is isolated.

Salmonellosis is an infectious disease of mammals and birds, proceeding very diverse, but most often in the form of typical toxicoinfections. The main transmission routes are food, less often - contact. HISTORICAL REFERENCE. In 1885, American microbiologists Salmon and Smith isolated a bacterial culture from the meat of sick pigs, which later became a large group of microorganisms called
- Paratyphoid (salmonellosis)
This is an infectious disease of young birds of many species, but ducklings and goslings are mainly affected. The causative agent of the disease is salmonella. A person is also susceptible to the disease. The incubation period of the disease can last from 12 hours to 7 days. Most often, young animals get sick - at 2-6 weeks of age, the bird most weakened and affected by other diseases is most susceptible to the disease.
Richard L. Guerrant The genus Salmonella consists of three species, which include more than 2,000 different serological types. Serotia differ significantly in their degree of pathogenicity, however, almost all of them are pathogenic for animals and humans. Strict specificity in the choice of hosts is characteristic of certain serotypes, such as S. typhi, which in natural
