犬寄生虫病多见于体外寄生虫和肠道寄生虫,而犬心丝虫引起犬死亡的病例在海城还比较少见。 2006年9月,畜主携死亡的黑丹犬来我中心,要求对死亡的犬进行解剖,查明病因。据主诉此犬病程较长,有2个月的时间病犬厌食,目渐消瘦,最早期症状咳嗽,畜主误认为上呼吸道感染,静脉注射过抗生素,病情略有好转。但后期病情加重,腹围增大,全身浮肿,拒绝主人抚摸,触诊疼痛,呼吸困难,多次注射抗生素以及血清无效,最后死亡。  相似文献

应用牛腹腔唇乳突丝虫(Setarialabiatopapillosa)提纯抗原(简称牛丝虫G抗原)和抗人IgG酶标记物的酶联免疫吸附试验,检测227例班氏丝虫病人血清的阳性率为95.59%;检测132例健康人血清的假阳性率为2.27%,10例血吸虫病人血清的阳性率为0。应用牛丝虫G抗原和马来丝虫抗原同步检测50例班氏丝虫病人血清的阳性率,前者为98%,后者为86%,二者有显著差异(p<0.05)。因此认为,牛丝虫G抗原可以作为人丝虫病的异种抗原诊断试剂。  相似文献

Carval syndrome is a severe heartworm infection where the worms have migrated to the right atrium and vena cava; this condition is associated with a myriad of clinical signs. Several non-surgical and interventional methods are currently used for mechanical worm removal. However, the success rate and complications related to these methods are heavily dependent on methodology and retrieval devices used. In this study, we developed a catheter-guided heartworm removal method using a retrieval basket that can easily access pulmonary arteries and increase the number of worms removed per procedure. With this technique, we successfully treated four dogs with caval syndrome.  相似文献

Thoracic radiographs of 28 dogs with heartworm disease and right heart failure were evaluated subjectively and objectively. Radiographs of all dogs were abnormal. Abnormalities were consistent with those previously reported for heartworm disease but were more severe than those identified in another group of heartworm dogs that did not have right heart failure. The right ventricle and right caudal labor pulmonary artery were enlarged in every dog. The main pulmonary artery, right cranial lobar pulmonary artery, and caudal vena cava were enlarged in 24, 25, and 17 dogs, respectively. Radiographically apparent pathologic pulmonary conditions were present in 25 dogs. Pleural effusion was not identified.  相似文献

Pulmonary intravascular macrophages (PIMs), large (20-80 microm diameter) monocytes are present in sheep, pigs, and horses, but not in dogs, rats, rabbits, or primates. The present study evaluated the phagocytic activity of various organs in cats and dogs and determined the influence of Dirofilaria immitis infections on PIM activity. Live or dead adult heartworm (HW) was transplanted via jugular venotomy into cats and dogs. Cats (four per group) were allocated to five groups: surgical controls--no HW, dead HW for 1 week, live HW for 1 week, dead HW for 3 weeks, or live HW for 3 weeks. Radioactive technetium (Tc-99m, 1.2mCi in 0.3ml) sulfa-colloid was injected intravenously. All cats with HW were clinically asymptomatic and developed radiographic pulmonary parenchymal changes. No gross changes were visible at necropsy for cats with HW; inflammatory changes were less severe in cats with live HW. In cats with dead HW for 3 weeks, worms were present but folded, flattened, and located in distal pulmonary arteries. Uninfected control dogs and those with dead HW did not demonstrate any PIM activity. In control cats, lungs were the primary phagocytic organ after systemic IV colloid injection (72.5% of the total recovered radioactive dose). The lung and liver together represented over 95% of the recovered Tc-99m colloid in all cats. In each group of cats with HW, phagocytic activity of the lung was significantly less (p < 0.001) than the PIM activity of controls. Cats with dead HW at 1 week (50.1%) had a significant (p < 0.019) decrease in PIM activity compared with cats with dead HW at 3 weeks (59.5%). The PIM activity in cats with live HW was significantly decreased (p < 0.001) from that in groups with dead HW, but there was no significant difference between the two groups infected with live worms. There were no significant differences in recovery between any groups in pairwise analysis of the spleen, heart, skeletal muscle, kidney, bone marrow, or blood. Significant increases (p < 0.001) in liver activity for each group inversely reflected the decreased lung activity; consistent with increased hepatic uptake of Tc colloid \"escaping\" a relatively suppressed lung macrophage system. Transmission electron microscopy confirmed PIM glycocalyx changes and vacuolization, moderate Type 1 cell damage and Type II cell hypertrophy in cats with dead HW. There was no evidence of PIM death. The significant decrease in PIM activity in groups with dead HW and a greater decrease in groups with live HW are consistent with a down-regulation of PIM function in cats with live HW.  相似文献
