Escherichiosis

Escherichiosis (colibacteriosis) is a spring disease of bee colonies caused by Escherichia coli and accompanied by the death of adult bees. Distributed where there is a high concentration of animals

Etiology. The causative agent is a tagged Escherichia coli.- gram-negative, motile and motionless bacillus 0.4-0.6 x 1-3 microns in size. Spore and capsules do not form an optional aerobic.

It has many serovariants that differ in antigenic structure, which are established using specific sera.

Symptoms and course are approximately the same as with salmonellosis.

Abdomen enlarged, diarrhea.

The diagnosis is made on the basis of epizootological data, clinical signs and the results of bacteriological analysis.
If the selected microorganisms are not typed, they put a biological test on bees in cages. The diagnosis is considered positive if the isolated E. coli has an antigenic composition or pathogenicity is determined.

Differential diagnosis: exclude salmonellosis, nosematosis.

Treatment. Chlortetracycline, chloramphenicol, gentamicin, streptomycin 0.2 g / l, 1-2 days before recovery.

Prevention and control measures. As with salmonellosis.

Escherichiosis

  1. ESHERICHIOSIS
    Escherichiosis (lat., English. - Escherichiosis; Escherichiosis) - a disease of adult bees, characterized by diarrhea and death as a result of sepsis. The causative agent of the disease. The causative agent of escherichiosis (colibacteriosis) of bees is Escherichia coli (E. coli), which does not differ in properties from the causative agent of the disease in animals (see part 1, Escherichiosis). Honey bee, bumblebees, like most others
  2. ESHERICHIOSIS
    Escherichiosis (lat., English - Escherichiosis; colibacteriosis, colienteritis, colisepsis) is an acute zoonotic disease of young animals of many species, manifested by septicemia, toxemia and enteritis, dehydration of the body, damage to the central nervous system, growing depression and weakness, and pneumonia (see color insert). Historical background, distribution,
  3. Escherichiosis
    Escherichiosis (echerichiosis) is an infectious disease accompanied by profuse diarrhea, signs of severe intoxication and dehydration. Etiology. The causative agent of the disease are enteropathogenic strains (E. coli) of E. coli, which are characterized by high virulence and the presence of hemolytic properties. The causative agent of the disease is an optional anaerobic and represents
  4. Escherichiosis
    Escherichiosis - acute infectious diseases mainly of young children, caused by various serovars of pathogenic Escherichia coli. They are characterized by the development of pathological processes in the gastrointestinal tract with infectious-toxic and diarrheal syndrome, less often - damage to other organs or generalization of the process up to sepsis. Certain strains of E. coli may
  5. Escherichiosis
    Escherichiosis (escherichiosis) is a septicemia-like disease with symptoms of intoxication. Etiology. The causative agent of the disease is a pathogenic E. coli bacillus, with hemolytic activity, gram-negative, does not form a spore. It has adhesive properties (K88, K99). Bacterial serotypes 08, 09 form a capsule. In the external environment retains its biological properties in
  6. Salmonellosis and other acute intestinal diarrheal infections
    Training target: using diagnostic algorithms, be able to establish a diagnosis of salmonellosis, escherichiosis and other acute intestinal diarrheal diseases, determine the clinical form, severity, stage of the disease, and prescribe adequate treatment; conduct dispensary observation. Assignment for independent study of the topic. Using the textbook and lecture material for the acquisition
  7. Toxicosis with Exicosis
    Toxicosis with exicosis is a pathological condition that develops, as a rule, with intestinal infections, characterized by the presence of toxemia, dehydration (exicosis) and, in some cases, bacteremia with the development of septic foci. Exicosis - a sharp decrease in the water content in the body due to insufficient intake or excessive excretion of it. Etiology. All acute intestinal infections taken
  8. differential diagnosis and treatment
    Differential diagnosis of dysentery with other acute diarrheal diseases (salmonellosis, escherichiosis, intestinal yersiniosis, staphylococcal enterotoxin poisoning, cholera, amoebiasis). Differential diagnosis of dysentery, cholera and salmonellosis.
  9. Edematous Piggy
    Edematous disease (lat. - Morbus oedematosus; English - Oedema disease; enterotoxemia, enterotoxic escherichiosis) is an acute illness of post-dark piglets characterized by hemorrhagic gastroenteritis, toxicosis, damage to the central nervous system and edema in the tissues. Historical background, distribution, hazard and damage. For the first time the disease was
  10. Colibacillosis
    Colibacteriosis (colibacteriosis) (Escherichiosis, colidia, colisepsis) is an acute disease of young farm animals, manifested by septicemia, toxemia and enteritis. Etiology. The causative agent is Escherichia coli. This is a gram-negative bacillus with rounded ends, 2-3 x 0.4-0.6 μm in size, does not form a spore, does not form a capsule, with the exception of individual strains
  11. LABORATORY DIAGNOSTICS
    main indicators: specific gravity of blood plasma, monitoring of hematocrit, electrolytes • specific diagnostics: • microscopy of bowel movements - a characteristic form of pathogens (arranged in parallel in the form of fish schools, mobile). This allows you to make a preliminary diagnosis. • The classical study at the first stage involves sowing 1% alkaline peptone water followed by
  12. Respiratory Mycoplasmosis
    Respiratory mycoplasmosis (mycoplasmosis respiratopia) - (disease of the air sacs) is an infectious disease characterized by catarrh-fibrinous inflammation of the respiratory system, synovitis, and exhaustion. Etiology. The causative agent of the disease is the optional aerobic Mycoplasma gallisepticum, which occupies an intermediate position between bacteria and viruses. Mycoplasmas do not have typical
