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 certain strains of serogroups 08, 09, 0101. Escherichia grow well on ordinary nutrient media at a temperature 37 ° C and pH 7.2-7.4. In soil, manure, water and livestock buildings, the pathogen lasts 1-2 months. They have a detrimental effect on Escherichia: 4% hot sodium hydroxide solution, clarified bleach solution with a content of 3% active chlorine, 20% suspension of freshly slaked lime.

Epizootological data. Young animals of all types of farm animals are susceptible to colibacteriosis, starting from the first days of life. The source of the causative agent of the infection are patients and bacteria carriers. The pathogen is transmitted with colostrum, feed, water, through manure, litter and care items contaminated with feces and urine. Infection often occurs by alimentary route, less often - by aerogenic and intrauterine. The disease proceeds in the form of enzootia.

The course and symptoms. Colibacteriosis of calves, piglets, lambs occurs in enteric, enterotoxemic (edematous) and septic forms. The course of the disease is super-acute, acute, subacute and chronic. The incubation period from several hours to 2 days.

The ultra-acute course of colibacteriosis corresponds to the septic form of the disease and is inherent in newborns in the first 1-3 days. It is accompanied by refusal of food, a sharp increase in body temperature to 41-420C, increased heart rate, respiration and high mortality. The acute and subacute course corresponds to enterotoxemic and enteric forms of the disease, is more often observed at 3-5 days of age and is accompanied by general depression, profuse diarrhea. Feces are liquid, yellowish or gray-white in color with gas bubbles.

Diagnosis.
Colibacteriosis is placed taking into account epizootological data, clinical signs, pathological changes and the results of bacteriological studies. The diagnosis is considered established if the selected culture is assigned to the genus Escherichia, is typed or pathogenic for laboratory animals; when isolating a culture of Escherichia, with one or more types of adhesive antigens.

Differential diagnosis. Colibacteriosis is differentiated from diarrhea of ​​non-infectious origin, salmonellosis, streptococcosis, pasteurellosis, adeno-, rota- and coronavirus infections. In piglets additionally from viral gastroenteritis, dysentery.

Treatment. It is necessary to begin treatment when the first signs of the disease appear. Bacteriophage, hyperimmune serum, gamma globulin are used. Antibiotics are prescribed in accordance with the results of determining the sensitivity of the selected pathogen, the most effective are (enroxil, flumequin, kanamycin, cobactan, gentamicin, etc.), and sulfonamide (sulfazole, sulfadimethoxine, etc.) and nitrofuran (furazolidone, furazidine, etc. can also be used. .) preparations. Symptomatic agents are used to restore water-salt metabolism, acid-base balance, neutralize toxins and compensate for the deficiency of proteins, carbohydrates and vitamins in the body.

Prevention and control measures. Prevention is based on a complex of organizational, economic, anti-epizootic, zootechnical, veterinary-sanitary and zoohygienic measures aimed at increasing the resistance of mothers and young animals, ensuring hygiene of childbirth, and also preventing infection of animals through environmental objects. Timely vaccination of pregnant cows and pregnant sows, passive immunization of newborns with specific immune serum and gamma globulins. In the first hours of life, non-specific globulins, ABA, PABA, acidophilus are used as prophylactic agents.

Colibacillosis

  1. COLIBACTERIOSIS (COLIBACTERIOSIS)
    Colibacteriosis is an acute infectious disease that affects mainly young animals. The disease is characterized by inflammatory processes in the gastrointestinal tract, accompanied by severe diarrhea. Etiology. Colibacteriosis can be caused by different representatives of E. coli and E. paracoli. The strains isolated from the organs of the fallen puppies had good enzymatic activity. By
  2. Colibacteriosis
    Colibacteriosis is a disease of the digestive or genitourinary system caused by Escherichia coli, a typical representative of the normal intestinal microflora of carnivores. Under certain conditions (stress, some diseases, antibiotic therapy), these bacteria become pathogenic, causing acute gastrointestinal upsets, pyelonephritis, as well as a difficult to treat cat disease like

    Colibacillosis
  4. Colibacillosis
    This is a disease that is caused by coli coli. Susceptible birds of all ages and their embryos. Most susceptible chickens are between one and 120 days old. The causative agent is resistant to environmental influences. Infection occurs both aerogenically and through the digestive tract with contaminated feed, water and through infected eggs from dysfunctional farms. Clinical
  5. Definition
    - colibacteriosis is a factorial bacterial infectious disease of newborn calves, piglets and lambs, which is not characterized by relay transmission of the pathogen. Calf disease is characterized by enzotism, refusal to feed, profuse debilitating diarrhea, dehydration. Newborns fall ill with colibacillosis throughout the year. The number of cases is
  6. Diagnostics
    - they diagnose colibacteriosis on the basis of clinical, epizootological, pathoanatomical data and laboratory studies. Clinical diagnosis - from the first day of life, newborns suffer from debilitating profuse diarrhea. The body temperature is normal. Only in certain patients it rises to 40 ° C, sometimes slightly higher. Calves refuse to feed, lie. On the
  7. Swine rotavirus diarrhea
    Swine rotavirus diarrhea (porcine rotavirus infections) - an infectious disease of piglets, mainly 3-6 weeks of age, characterized by the development of diarrhea syndrome. Etiology. Pathogen RNA-containing virus belonging to the Reoviridae family, genus Rotavirus (Porcine rotavirus). 7 different rotavirus serogroups (A - J) were detected, but diarrhea in pigs is most often
  8. Epizootology
    - on the collective and state farms of our country, colibacteriosis, as a massive disease of calves, began to be recorded in the thirties and forties, after the socialization of animals and keeping them in large groups. At that time, characteristic of livestock farms was a low level of sanitation and hygiene. In primitive livestock buildings, conditions were formed for
  9. 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,
