one dog Eperythrozoon.
clinical symptoms:
naturally infected dogs, mostly hidden by, no obvious symptoms, little change in appetite and spirit are often not easily be found . When suffering from stress in dogs subjected to a (transport, hunger, fatigue) stimulation decreased body resistance, may show acute after the symptoms clear. Body temperature to 40 ℃, lack of energy, limb weakness, lying in lethargy, nose dry, pale conjunctiva or yellow dye, heart rate 130 -180 times per minute, respiratory 30 -60 times per minute, decreased appetite, vomiting, less stool and dry when the thin, small and yellow urine. In severe cases, death 3 days -5 days. Most become chronic, showing varying degrees of anemia, jaundice, weight loss, fever, duration of up to one month or more, some dogs suffering from secondary bacterial infections due to diarrhea or diarrhea, extreme weight loss, loss of appetite waste must.
necropsy lesions:
severe cases of acute blood type and thin, easy to freezing, the body mucosa with varying degrees of jaundice, swollen lymph nodes, lung edema, pericardial effusion, heart fat yellow crown staining, myocardial relaxation, ascites, liver jaundice, gallbladder filling, thick bile, spleen enlargement, soft texture. In addition to secondary enteritis and other diseases, no significant change in other tissues and organs.
Diagnosis:
seized under the Ministry of clinical symptoms and preliminary diagnosis can only be changed, subject to laboratory diagnosis. Check blood pressure drop through the specimens, such as found in spherical, ovoid, short rod-shaped or star-shaped bodies attached to or separated from the plasma surrounding red blood cells when, can be confirmed.
treatment:
1. tetracycline and oxytetracycline of the disease has a good effect. Oral administration of 66 mg per kilogram of body weight once a day, once every 14 days. Intravenous injection of 10 mg per kg of body weight -20 mg, 55 glucose plus saline concentration of 0.5% made of injection, once daily, once every few days. Severe cases can be combined with a strong heart, antiemetic and hepatoprotective drugs symptomatic treatment. If the secondary intestinal or respiratory infections should be treated with intramuscular injection of streptomycin and other drugs.
2. blood worms or blood worms kill clean injection, by 0.2 ~ 0.3mL/kg weight, intravenous or intramuscular injection, repeated injection of 1-hour interval of 24.48 times, more than 90% cure rate. Of serious and debilitating disease of dogs, with cardiac, infusion, correct acid-base balance, with 3% glucose and saline 200mL, 2.5% Vc10mL, 10% intravenous infusion of caffeine sodium benzoate 5mL to good effect.
Prevention:
Eperythrozoon mostly due to the medium of infected livestock arthropods, so to get rid of mosquitoes and scabies mites, lice, ticks and other ectoparasites, reduce or eliminate all negative stress factors. Conditions can be carried out on dogs with blood group Eperythrozoon examination was to detect latent infection in dogs, and take the isolation, treatment, elimination and other measures to isolate the source of infection.
II.
canine toxoplasmosis toxoplasmosis Toxoplasmosis is caused by the people, livestock and wild animals were suffering from a protozoosis.
all susceptible animals, cats are the main source of infection. When the cat swallowed cysts containing Toxoplasma gondii parasites in animal tissues or the form of development and maturation of oocysts, the parasite enters the cat's digestive tract, invade intestinal epithelial cells, in cells produce large amounts of fission merozoites, to a certain stage, some merozoites into gametophytes, gametophytes produce the final oocyst reproductive gametes. With cat faeces oocysts excreted in the appropriate environment and development by 2 to 4 days to become infective oocysts. Oocysts have a stronger resistance to the outside world, can remain infectious at room temperature 1 to 1 and a half years. Toxoplasma gondii in cats because the body can only ######ual reproduction, so the cat is the final host.
dogs and other animals, the main route of transmission is the digestive tract, followed by the placenta, skin and mucous membranes. Toxoplasma into the dogs, the invasion of nucleated cells in the cytoplasm by budding a######ually way. When the insect toxic strains of strong, weak host resistance, which proliferate, causing acute illness. Conversely, weak poison insect strains, host resistance is strong, the disease develops slowly or not clinical symptoms, parasites remaining in the formation of cysts in some type of tissue parasites. Toxoplasma gondii in dogs can only be due to a######ual reproduction, so the dog is the intermediate host.
symptoms: suffering from dog depression, body temperature increased to 40 ~ 41.5 ℃, anorexia,
mulberry bag, cough, eyes, noses and increased secretions, mucous membranes pale, or even violently bloody diarrhea, vomiting, and the emergence of a small number of cases of paralysis of concurrent phenomenon, pregnant bitches miscarriage or premature birth, early symptoms are similar to canine distemper and canine infectious hepatitis.
Diagnosis:
early symptoms of this disease in dogs with canine distemper and infectious hepatitis are very similar clinical symptoms alone is difficult to distinguish. Conducting epidemiological analysis, and comprehensive clinical judgments, they still can be confirmed by laboratory diagnosis.
treatment:
1, sulfadiazine (SD): the first dose of 220mg/kg, maintenance dose 110mg/kg, twice a day for 2 to 3 days.
2, 6, trimethoprim sulfa pyrimidine (SMM): 25mg/kg, twice a day for 2 to 3 days.
III. piroplasmosis
horseleech amine drugs also have a therapeutic effect on its ...
added: there is a new disease (Patong worm) is a
four species of blood parasites, Babesia:
【】
pathogenic Babesia is a parasite of red blood cells in the blood of a blood disease. The blood smear under a microscope can be found to do Babesia, Babesia parasites
pear-shaped arrangement of double-long 4 ~ 5UM, one end pointed, one end of the round, there is a void. Parasites of red blood cells is greater than 1 / 5. The largest is 7UM. Babesia
Gibbs, microscopic parasites were ring,
mulberry sale, round and so on. A red blood cell can have more than 30 worms.
【Symptoms】
body temperature, 40 degrees, urine from yellow to dark brown. Containing proteins. Or contain hemoglobin. The normal number of red blood cell count 1 / 2 or 1 / 3
white blood cell count increased. High temperature 3 to 5 days, 5 to 10 days normal body temperature. Irregular relapsing fever type. Dogs suffering from a high degree of anemia, jaundice, palpable enlargement of the spleen
.
the cases often leads to ear, back and other parts of the skin of the extensive bleeding.
diagnosis】 【
clinical symptoms of the disease, the incidence of the season,
mulberry Handbags, the epidemic, whether the local host ticks and other insects, such as dogs to tick
insect bites and found that body temperature suspected cases, can be done
hemoglobin test, found lower than normal hemoglobin, 120 ~ 180 / L,
do blood smear, red blood cells were found to have parasites, can be confirmed.
【Treatment】
1, cone basket element, the first choice of drug per kilogram of body weight 5ML, dubbed by 1% saline solution intravenously, configuration, injecting drug use, should be heated melting,
; with cotton gauze filters, flow of steam sterilization for 30 minutes until the temperature dropped to 30 degrees for slow injection, quickly kill parasites.
2, Diminazene 3 mg per kilogram of body weight of 7% saline solution once dubbed intramuscular injection, if necessary, re-injection after an interval of 2 days, 1 to 4 times,
chloe bags, you can receive a certain
effect, but if the medication was found swinging hindquarters, standing instability, allergic reactions, it is timely rescue, stopping the treatment.
3, Spring Acre 0.25 mg per kg body weight, subcutaneous injection, before injection of atropine to reduce the prevention of side effects is too large.
five pathogenic】 【
blood filariasis, also known as dog heartworm
or Dirofilaria filariasis, a major parasite in the heart of the right ventricle in dogs and pulmonary artery. Caused by circulatory disturbance. Dyspnea, and anemia
parasites yellow white,
dolce gabbana handbag, slender fan-shaped, male 12 to 18 cm long,
coach handbags, circling back to the tail number, female 25 to 30 cm long, straight tail teaching, the larva is called micro-
silk larvae, 220 to 360 microns long, made in the blood sport hunting or ring.
【Symptoms
cough, fatigue, loss of appetite, thin, anemia, heart disorders if the tricuspid and pulmonary parasites occurs when dyspnea, ascites, limb
edema, pleural effusion and pulmonary edema.
】 【diagnosis of the disease by mosquitoes (intermediate host) bites, summer is generally popular.
testing methods:
1, direct smear:
direct images of blood, preferably 23:00 ~ 12 blood samples, microscopic examination
; 2, the centrifugal method
insect collection of blood collected one milliliter of 2% formalin and 10 ml mixed, centrifuged 1500 rpm for 5 minutes, take deposits staining.
【Treatment】
1, Hai Qun: 100 mg per kg, orally, 1 time / day, and even served a week.
2, ivermectin, 0.05 to 0.1 mg per kg, subcutaneous injection.
These are two common parasitic disease of blood, please refer to.
