- Occurrence: common
- Location of illness: Abdomen/pelvis
Colibacillosis is a bacterial infectiousInfectious describes the ability of a pathogen to be transmitted from one individual to another and trigger an infection. It also refers to diseases caused by such pathogens. disease in dogs caused by the bacterium Escherichia coli (E. coli). This infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. can cause a variety of symptoms, ranging from mild gastrointestinalGastrointestinal refers to the gastrointestinal tract, a system that extends from the oral cavity to the anus and is responsible for the digestion of food and the absorption of nutrients. discomfort to serious systemic diseases.
The most important facts at a glance
Colibacillosis in dogs is caused by pathogenic strains of the bacterium Escherichia coli, which is normally found in the intestineThe intestine is the medical term for the gut, including the small intestine (intestinum tenue) and the large intestine (intestinum crassum).

The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is based on the anamnesis, the clinical symptoms, and the detection of pathogenic E. coli strains in the feces.

Therapies can be medicinal, surgical, or through other medical interventions.. Treatment varies depending on the severity of the symptoms. Milder cases can be treated with rehydration and dietary management, while more severe infections require antibiotics and possibly more intensive care.

Not all strains of E. coli are pathogenic; some are part of the normal intestinalIntestinal refers to the intestine, the part of the digestive tract that extends from the stomach to the anus.

In the context of veterinary medicine, it often refers to the absorption of nutrients, drugs, or toxins from the digestive tract into the bloodstream.. Pathogenic strains, on the other hand, can cause infections if they get outside the intestineThe intestine is the medical term for the gut, including the small intestine (intestinum tenue) and the large intestine (intestinum crassum).

Pathogenic E. coli strains are divided into various categories, including enterotoxigenic E. coli (ETEC), enteropathogenic E. coli (EPEC), and enterohemorrhagic E. coli (EHEC). These strains produce toxins or cause damage to the intestinalIntestinal refers to the intestine, the part of the digestive tract that extends from the stomach to the anus.

Symptoms
The symptoms of colibacillosis in dogs can vary depending on the age, immune status of the dog, and virulence of the E. coli strain. In young puppies whose immune systems are not yet fully developed, the symptoms may be more severe.
Typical symptoms include DiarrheaDiarrhea refers to the condition of frequent, watery bowel movements, which can be a sign of infections, digestive disorders, or other health problems., which may be watery or bloody, Vomiting, loss of appetite, and lethargy. In severe cases, dehydrationDehydration occurs when the body loses more fluid than it takes in.

Systemic infections can occur when the bacterium enters the bloodstream. This can lead to Fever, shock, and multipleMultiple means manifold or repeated and is used to describe conditions or events that occur in multiple instances or at different locations. In veterinary medicine, this may indicate multiple lesions, tumors, or other pathological changes. organ failure. Such severe cases require immediate veterinary treatment.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of colibacillosis is based on the anamnesis, the clinical symptoms, and the detection of E. coli in the dog’s feces. A stool examination in the laboratory can be performed to confirm the presence of pathogenic E. coli strains.
Cultures and sensitivity tests are important to identify the specific strain and determine the appropriate antibiotic therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions.. In some cases, a blood testA blood test is a laboratory procedure in which blood is drawn and analyzed to obtain information about the body's health. It can include various parameters such as blood sugar, blood count, liver and kidney values. may also be necessary to assess the extent of the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. and rule out other possible causes for the symptoms.
Therapy
The treatment of colibacillosis depends on the severity of the symptoms. In mild cases, supportiveSupportive refers to supportive treatments that aim to alleviate symptoms and improve quality of life without directly treating the underlying cause of the disease. therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. may be sufficient, including the administration of electrolyte solutions for rehydration and dietary management to relieve the intestines.
In more severe cases, antibiotic therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. is necessary to combat the infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease.. The choice of antibiotic is based on the results of sensitivity tests to ensure effective treatment.
In addition, probiotics can be administered to support the restoration of normal intestinalIntestinal refers to the intestine, the part of the digestive tract that extends from the stomach to the anus.

In cases of systemic infections, more intensive care, including intravenous fluids and monitoring in the hospital, may be necessary.
Prognosis and follow-up care
The prognosis for dogs with colibacillosis is generally good if the disease is detected and treated early. Most dogs recover completely with the right treatment.
In more severe cases, or if treatment is delayed, the prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. may be less favorable, especially in young puppies or dogs with weakened immune systems. Rapid and appropriate veterinary intervention significantly improves the chances of a full recovery.
Prevention
The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of colibacillosis in dogs is based on good hygiene and management practices. This includes regular cleaning of living areas and feeding areas to minimize the spread of bacteria.
