| Toxoplasmosis is toxoplasmosis by Eimeriidae Sarcocystis, Toxoplasma gondii subfamily, a zoonotic disease caused by parasitic protozoa, cattle and sheep, cats and other animal cells, the main feature is the "Swine High fever". When I visited the clinic, I have encountered this kind of cases many times, and the diagnosis and comprehensive prevention and treatment have achieved good results: Prevalence It can happen all the year round, and it occurs frequently in summer. All ages can be infected. The minimum age is 25 days. Insects, such as flies and insect bites, can be infected with contaminated feed, drinking water, diseased pigs, excreta and cough, and temporal and spatial droplets can also transmit pathogens. Clinical symptoms At the early stage of depression, hair dull, skin with blood stasis plaque, especially in the back and abdomen, vomiting pig disease, some cough, conjunctival flushing, eyelid gum, black, blue, constipation, most pull stem dung dung, covering the surface of a small amount of mucus, some blood, late diarrhea, drainage kind of purulent malodorous feces, temperature 40 to 42 DEG C, and some normal temperature, a continuous fever. Seriously, the nose dry, nostrils are serous and mucinous or purulent mucus outflow, dyspnea, shivering, gait instability, dyspnoea, obvious abdominal breathing. Most pigs like to eat some pig ear disease of loess, scab skin, piglets infected urine was brown, also some sick pig diarrhea, also some neurological symptoms such as cramps. Necropsy change The diseased pig's pores are oozing and bleeding, and there are obvious blood stasis plaques on the back, buttocks and lower abdomen. Systemic lymph node enlargement, pulmonary edema, swelling of the spleen is brownish red, liver red red, cloudy swelling, there are large necrosis of the liver, kidney swelling is yellowish brown, there are bleeding points. Colonic, duodenal, and rectal ulcers. Diagnosis Toxoplasmosis symptoms, pathological changes and epidemiology and swine fever are similar, the clinical features: high fever, blood stasis, eyelid black spots, not to do so as the basis of diagnosis, laboratory examination. Blood smear method: Pig venous blood 2ml drops on the glass slide is made by conventional push blood films, natural drying, drop 2 to 3 drops of blood on the formaldehyde membrane, which then fixed with Wright's staining, observe the morphology under microscope under oil microscope, can diagnose. Indirect hemagglutination test: Pig venous blood 3ml, blood coagulation reaction plate produced by Shanghai 90 ~ V shaped microporous organic glass plate, toxoplasmosis diagnosis was provided by Nanjing veterinary research, according to the instructions specified in the program. Prevention measures The morninglight Honggong chain, intramuscular injection, 2 times 1 days, for 1 ~ 3 days. Second, the Xin rice first, intramuscular injection, 1 days 1 times, used for 1~3 days. In the course of treatment, with antibacterial agents, the first dose is 2 times the normal dose, after a normal amount, with the stomach to open the needle, 1 days, 2 times, 3~5 days to recover, the cure rate of 90%. If the intestinal infection, eat loess and other symptoms, first with sodium thiosulfate, gastric lavage, and then treatment; such as dry stool, with a laxative artificial mineral salt, farmers with lard; after dehydration, transfusion with antibiotics such as cephalosporins for treatment. Personal experience Early diagnosis, early treatment effect is better, such as timely detection, injection sulfa drugs, with anti-bacterial anti fever drug, create a new freezing point, 1 days, 2 times, 3 days to recover, the cure rate of 100%, but the dose must be accurate. Also available morninglight No. 1 with strong resistance or mixed treatment effect. In patients with intestinal symptoms, laxative, choice, lard than Glauber's salt, Glauber's salt excretion, the intestinal contents of toxic substances can not be completely discharged, and lard absorption slowly, excretion is slow, can complete the excretion of toxic substances. |
