Helicobacteriosis (Bacterial Stomach Infection with Helicobacter Species) in cats
- Occurrence: common
- Location of illness: Abdomen/pelvis
Helicobacteriosis is a bacterial stomach infection in cats caused by various Helicobacter species that can cause gastrointestinal problems.
The most important facts at a glance
Helicobacteriosis in cats is a bacterial stomach infection caused by various Helicobacter species. These bacteria are spiral-shaped and have flagella that give them mobility to colonize the gastric epithelium and cause Inflammatory conditions. Transmission likely occurs via the fecal-oral or oral-oral route, but the exact routes are not yet fully understood. Many cats are asymptomatic carriers, but factors such as the immune system, the amount of bacteria, and genetic predispositions can lead to an actual illness.
Common symptoms include chronic Vomiting, loss of appetite, Abdominal pain, and Weight loss. Diagnosis is challenging because the symptoms are non-specific. Endoscopy and biopsies are common diagnostic methods. Treatment includes antibiotics and medications to reduce stomach acid production. It is important to complete the entire treatment to avoid resistance.
The prognosis is generally good, especially with early diagnosis and treatment. Preventive measures such as good hygiene, regular veterinary examinations, and a low-stress environment are important to minimize the risk of infection. Contact with stray cats should be avoided, and quarantine is advisable for new cats in the household. Hand washing after handling cats is crucial to prevent the transmission of bacteria.
Causes
Helicobacter species are gram-negative bacteria that have adapted to the acidic environment of the stomach. These bacteria are spiral-shaped and equipped with flagella, which give them high mobility. They are able to colonize the gastric epithelium and cause Inflammatory conditions by irritating the mucous membrane. Various Helicobacter species have been identified in cats, including Helicobacter felis, Helicobacter heilmannii, and Helicobacter pylori, which also occurs in humans.
The transmission of the bacteria likely occurs via the fecal-oral or oral-oral route, meaning that infection can occur through contaminated food or water, but also directly from cat to cat. However, the exact transmission routes have not yet been fully clarified. The presence of the bacteria alone does not necessarily lead to disease symptoms, and many cats can be asymptomatic carriers.
The causes of an actual illness depend on various factors, including the animal’s immune system, the specific type of Helicobacter, the amount of bacteria, and possibly also genetic predispositions. Stress and other health problems can also contribute to an increased susceptibility.
Symptoms
The symptoms of Helicobacteriosis in cats can vary and range from mild to severe. Many cats show no obvious symptoms, even if they are infected with Helicobacter. In symptomatic cats, the signs can be non-specific and include various gastrointestinal complaints.
The most common symptoms include Vomiting, which may occasionally be bloody, loss of appetite, and Weight loss. Some cats also show signs of gastrointestinal discomfort, such as increased swallowing or Lip licking, which may indicate Nausea. In some cases, Diarrhea or constipation may also occur.
In severe cases or with prolonged untreated infection, cats may show signs of lethargy, weakness, and dehydration. A chronic infection can lead to inflammation of the gastric mucosa (gastritis), which is associated with Pain and discomfort.
Diagnosis
The diagnosis of a Helicobacter infection in cats can be challenging because the symptoms are often non-specific and can also occur with other gastrointestinal diseases. In addition, many cats are asymptomatic carriers. A comprehensive approach is therefore necessary to make an accurate diagnosis.
A commonly used diagnostic tool is endoscopy, in which a small camera is inserted into the stomach through the mouth. During this procedure, tissue samples (biopsies) can be taken to confirm the presence of Helicobacter bacteria under the microscope. The biopsies can also be examined for Inflammatory conditions or other abnormalities.
In addition, special tests, such as the urease test, can be used to detect the activity of Helicobacter, as these bacteria produce urease, an enzyme that converts urea into ammonia. However, these tests are not always specific enough to identify the exact species.
Therapy
The treatment of a Helicobacter infection in cats aims to eliminate the bacteria and alleviate the symptoms. A common therapy consists of administering a combination of antibiotics to kill the bacteria, as well as medications that reduce stomach acid production to protect the mucous membrane and promote healing.
Commonly used antibiotics include amoxicillin, metronidazole, and clarithromycin. Proton pump inhibitors such as omeprazole can help reduce acid production. The exact therapy is determined by the veterinarian based on the individual needs and health condition of the cat.
It is important to complete the entire course of treatment, even if the symptoms subside prematurely, to ensure that all bacteria are eliminated and no resistance development is promoted. Regular follow-up examinations may be necessary to monitor the success of the treatment.
Prognosis and follow-up care
The prognosis for cats with Helicobacteriosis is generally good, especially if the infection is diagnosed and treated early. Many cats respond well to treatment and recover completely, as long as there are no further complications or underlying diseases.
In cases where the infection has become chronic or the cat has other health problems, recovery may take longer. Regular veterinary care and follow-up are important to ensure that the cat has fully recovered and that there are no relapses.
Prevention
To minimize the risk of Helicobacteriosis in cats, it is important to pay attention to good general health and hygiene. Regular veterinary examinations help to monitor the cat’s health and detect potential problems early. A balanced diet that meets the cat’s nutritional needs strengthens the immune system and can help prevent infections.
Hygiene measures such as regularly cleaning food bowls, water bowls, and litter boxes are crucial to prevent the spread of bacteria. It is important to keep cats in a low-stress environment, as stress can weaken the immune system, which increases susceptibility to infections. If several cats live in the household, sick animals should be separated from healthy ones to avoid infection.
In addition, contact with stray cats should be avoided, as they may be carriers of Helicobacter bacteria. When introducing new cats into the household, a quarantine period is advisable to ensure that they do not transmit any pathogens. Finally, it is important to wash your hands regularly, especially after handling cats, to prevent the transmission of bacteria.
