Dog Diseases – Canine Paratyphoid
Canine Paratyphoid is an acute bacterial disease of dogs, also known as Salmonellosis. Its clinical symptoms are mainly sepsis and enteritis. The pathogen is Salmonella, which includes more than 2000 serotypes. There are more than 40 serotypes isolated from dogs, and the most common bacterial type that can cause clinical disease in dogs is Salmonella typhimurium. Bacteria-carrying phenomena in healthy livestock and poultry are quite common, especially Salmonella typhimurium, which often hides in the digestive tract, lymphatic tissue and gallbladder. When a certain inducement reduces the body’s resistance, the bacteria can proliferate and cause endogenous infection. After passing through susceptible animals, the virulence increases, which causes the spread of the disease. In this case, gastrointestinal infection is the main route of transmission.
(1) Clinical features The dog has sudden acute gastroenteritis, showing high fever, anorexia, vomiting and diarrhea, drainage-like and mucus-like stools, and severe bloody stools. The physique was rapidly exhausted, the mucous membrane was pale, and finally died of dehydration and shock. Young dogs often develop bacteremia and endotoxemia. At this time, the body temperature of the sick dog is lowered, the whole body is weak and the capillary is not filled properly.
(2) Laboratory tests can cause high fever, anorexia, vomiting and diarrhea in dogs, and it is more common for healthy livestock and poultry to carry salmonella. Therefore, it is difficult to make a final diagnosis based on clinical diagnosis alone. For dogs with the above-mentioned clinical manifestations, the spleen, mesenteric lymph nodes, liver, bile and other disease materials of dead dogs should be taken for bacteriological examination. Only when pathogenic Salmonella is found in the disease material, combined with the above clinical manifestations, can the final diagnosis be confirmed.
First, it is strictly forbidden to feed the meat of sick and dead animals to dogs. It is best to feed the dog with cooked meat, eggs, and milk.
second. The feeding and management equipment should be cleaned and disinfected frequently, and attention should be paid to eliminating rodents and flies.
Thirdly, if the sick dog is found to be isolated and treated in time. Specialized management, strictly prohibit contact between sick dogs and healthy dogs. Sick kennels, sports grounds, and eating utensils should be disinfected with 2% to 3% caustic soda solution, bleaching powder emulsion, 5% ammonia water and other disinfectants. The corpse should be buried deeply and it is strictly forbidden to eat it to prevent infection. Antibiotics can be used to treat sick dogs. Chloramphenicol has a good effect. The dosage is 0.02 g/kg body weight, 2 to 4 times a day for 4 to 6 days. Furazolidone, 0.01 g/kg body weight, is taken orally in 2 to 3 times for 5 to 7 days. Sulfadiazines also have a good effect, such as sulfadiazine (SD), the first dose is 0.14 g/kg body weight each time, and the maintenance dose is 0.07 g/kg body weight each time, twice a day. Continuous use for 1 week; application of synergistic sinomethamine 0.02～0.025 g/kg body weight each time, twice a day. Garlic can also be taken orally, that is, take 5-25 grams of garlic and mash it into garlic paste and take it orally. Or take it orally after making garlic tincture, 3 times a day for 3 to 4 days. also. Properly cooperate with infusions to maintain heart function, cleanse the intestines and produce ferment, protect the gastrointestinal mucosa and other symptomatic treatments.
