The following tests are recommended to confirm the diagnosis:
1. Fecal tests (flotation, smear, and zinc sulfate for Giardia) should be performed in all patients with diarrhea, as intestinal parasites are One of the most common causes of diarrhea in small animal patients. Multiple stool tests are sometimes required because some parasites are difficult to diagnose.
2. A complete blood count (CBC) result in salmonellosis may be within the normal range, although it may show anemia (low red blood cell count). Depending on the stage of the disease, the white blood cell count can decrease or increase.
3. Biochemical analysis helps to assess kidney, liver, protein and electrolyte status. Although the results of this test are usually within the normal range, it can help rule out other diseases similar to salmonellosis. For example, patients with sepsis may be screened for hypoglycemia in this test.
4. Urinalysis helps to assess kidney and hydration levels.
5. Abdominal x-rays are helpful in assessing the presence of abdominal organs, foreign bodies, or tumors. But in most cases of salmonella, this test usually finds nothing unusual.
6. Bacterial culture on feces is strongly recommended, as this is the only known way to confirm infection. It is important to know that Salmonella can also be cultured from the feces of normal animals, so positive cultures must be interpreted according to the specific individual and their clinical symptoms.
Your veterinarian may recommend additional tests to ensure optimal medical care. These are selected on a case-by-case basis:
1. Perform blood cultures on dogs suspected of having systemic infection.
2. Fecal serology, ELISA (enzyme-linked immunosorbent assay), may help diagnose certain diseases, such as: parvovirus.
3. Abdominal ultrasonography can be used if the previous diagnosis is uncertain. It is helpful in assessing the size, shape, and integrity of abdominal organs, especially in the assessment of intussusception or pancreatitis. This is a non-invasive procedure, but may require a referral to a facility that specializes in ultrasound testing.
4. Serum trypsin-like immunoreactivity (TLI) is a simple blood test that can be recommended for those with chronic diarrhea and body weight if previous tests are not well-diagnosed Lighten up on the dog.
5 Serum folate and cobalamin analysis are also blood tests that typically increase and decrease, respectively, in the presence of bacterial overgrowth in the small intestine.
6. Barium contrast of the upper gastrointestinal (GI) can also be considered, especially when accompanied by vomiting. It will help rule out foreign bodies detected on X-rays, as well as other obstructive causes of acute diarrhea. It also helps to assess bowel ulcers, which can assess the thickness of the bowel wall. It is more helpful in ruling out the cause of gastroenteritis than diagnosing Salmonella. Typically, a safe dye is injected into the pet through the mouth and then watched as it travels through the gastrointestinal tract. It is non-invasive and can usually be performed safely by your veterinarian, although referral to a specialist medical facility may sometimes be required.
7. Duodenoscopy or colonoscopy. These two tests are mainly used to evaluate part of the small intestine and colon with appropriate equipment and can be used in some patients. Biopsy can be done concurrently with microscopy and culture.
8. For those pets who are going to the veterinary clinic for abortion, it is necessary to check their bodies for Brucella, Toxoplasma and herpes virus.
In patients with fever as the main clinical symptom, additional diagnosis may be required. These include:
1, arthrocentesis to rule out polyarthritis
2, creatine kinase, electromyography or muscle biopsy to rule out polymyositis.
3. Cerebrospinal fluid (CSF) test to rule out encephalomyelitis.
In-depth information on treatment
Treatment of canine salmonellosis varies according to the type and severity of clinical disease. Depending on the severity of clinical symptoms or the stage of the disease, hospitalization may be recommended. Patients with sepsis, severe vomiting or diarrhoea, fever, and/or dehydration should be hospitalized for aggressive treatment and stable signs. Stable pets can be treated as outpatients, as long as their response to treatment is closely monitored and handled appropriately, keeping them quiet and comfortable, and remembering that isolation is the most important part of this process. With proper treatment, most sick dogs do well.
It is very important that all veterinary advice is strictly followed and any questions or concerns that arise during treatment are addressed immediately.
1. Diet management. Physiological resting of the gut through dietary restriction is the most important approach for the treatment of acute diarrhea with salmonellosis. Completely restricting food intake for a few hours allows the lining of the gut to heal better.
2. Foods should be reintroduced gradually, starting with a bland, easily digestible, low-fat diet, and eating small, frequent meals. Related foods include: poached chicken or beef, cottage cheese as a protein source, mixed rice or potatoes, and carbohydrates.
3. If the diarrhea improves, you can gradually return to the original diet within 2-3 days.
4. Some patients with acute diarrhea may require fluid therapy to correct dehydration and acid-base disturbances, replenish electrolyte deficiencies, and provide protection for ongoing losses.
5. Antibiotic treatment of salmonellosis is controversial. In those dogs that are healthy or have acute diarrhea, the use of antibiotics may promote a carrier state, which is a big no-no. However, they may be beneficial in animals with bloody diarrhea, shock, fever, or sepsis. In conclusion, specific antibiotics should be selected based on culture and susceptibility results. Enrofloxacin (Baytril?), chloramphenicol, and sulfamethoxazole are generally the most effective antibiotics against Salmonella.
6. Blood transfusion may be beneficial to critically ill pets with sepsis.
7. Gut protectants and sorbents are drugs that coat
, lubricate and protect the gut and can help stimulate the lining of the gut.
Follow-up care
Optimal treatment usually involves a combination of home care and professional veterinary care. Follow-up is critical, especially if your pet does not improve quickly.
1. Take the medicine as prescribed by the doctor. Notify your veterinarian promptly if you are having trouble treating your pet.
2. Repeat fecal culture for several months to assess the development of the disease.
3. Keep pets healthy, provide proper nutrition, regularly clean and disinfect your pet’s environment, etc.
4. Observe your pet’s general activity level, appetite, and general behavior, and monitor for any signs of recurrence to prevent reinfection.
5. Remember, Salmonella is highly contagious.
