为了解山东省青岛市猫疱疹病毒Ⅰ型(FHV-1)的流行情况,2019年6月至2021年6月共采集猫眼鼻拭子样本218份,提取样本DNA后利用PCR方法进行FHV-1核酸检测,共检出阳性样本22份,阳性率为10.1%(22/218)。宠物救助站猫的FHV-1阳性率(16.7%)略高于其他来源猫,2~6月龄幼猫的FHV-1阳性率(13.6%)略高于成年猫(7.0%),成年公猫阳性率(7.3%)稍高于成年母猫(6.7%),但各组间均无显著性差异(P>0.05)。对2021年3月采集的60份猫血清进行了FHV-1中和抗体检测,共检出阳性样本40份,抗体阳性率为66.7%。结果表明,青岛市猫群中存在一定的FHV-1流行,抗体保护水平不高,应加快国产FHV-1相关疫苗的研制,及时对猫进行免疫预防。 相似文献

北京地区犬猫弓形虫病流行病学调查 总被引：1，自引：0，他引：1
为初步调查北京地区犬猫弓形虫感染的流病学特征,用酶联免疫吸附试验(ELISA)方法检测2010年5月至2011年4月采集的家养犬猫、流浪猫血清样本.其中,家养犬血清样本1876份,家养猫血清样本561份,检测发现,家养犬动物弓形虫IgG抗体阳性率24.9％;家养猫弓形虫IgG阳性率21.2％;同时检测流浪猫样本201份,阳性率30.3％.家养犬弓形虫血清抗体阳性率不同季节间差异显著(P＜0.05),夏季最高,为30.0％,家养猫弓形虫血清抗体阳性率不同季节间无显著差异(P＞0.05).不同性别犬猫弓形虫血清抗体阳性率无显著差异(P＞0.05).随着年龄增长,犬猫弓形虫抗体阳性率均有明显增长.对25例弓形虫抗体阳性家养犬病例和37例弓形虫抗体阳性家养猫病例进行了回访调查,结果发现,该62例动物主人的弓形虫检测结果均为阴性. 相似文献

采用酶联免疫吸附试验（ELISA）检测194份犬猫血样,测得弓形虫IgG抗体阳性血清36份,阳性率为18．56％。不同来源的犬猫血清弓形虫IgG抗体阳性率不同,流浪犬猫的平均阳性率为27．3％,其中流浪犬阳性率最高为30．77％,其次流浪猫阳性率为25％,农村犬阳性率为22．86％,养犬场犬阳性率为15％,宠物犬阳性率为12．5％。不同来源的犬猫之间感染率差异不显著（P〉0.05）,宠物猫样本数少,未检测出阳性血清。胶体金免疫层析法和酶联免疫吸附试验对比试验显示,这两种方法对猫的弓形虫抗体检测结果基本相符。 相似文献

为了解广东省东莞市犬猫中狂犬病、弓形虫病、布鲁氏菌病3种重要人兽共患病的抗体水平,采集东莞市32个镇（街）1 303份犬猫血清样品,其中犬1 174份、猫129份,应用酶联免疫吸附试验（ELISA）进行3种疫病的血清学检测。结果显示：犬猫狂犬病免疫抗体阳性率为80.74%,仅在犬中检出弓形虫抗体阳性,抗体阳性率为0.85%,未检出布鲁氏菌抗体阳性样品。宠物型犬猫狂犬病免疫抗体阳性率显著高于土养型（P <0.01）,> 3岁犬猫的抗体阳性率显著高于3岁及以下犬猫（P <0.05）;土养犬弓形虫抗体阳性率显著高于宠物犬（P <0.05）,<1岁犬阳性率显著高于1岁及以上犬。结果表明：东莞市犬猫狂犬病免疫抗体阳性率较高,免疫效果较好,但存在犬弓形虫的潜在感染风险;犬猫饲养方式和年龄会对抗体阳性率产生一定影响。结果提示,应加强犬猫3种重要人兽共患病的监测,根据监测结果制定针对性的防控措施。本调查基本掌握了当前东莞市犬猫3种重要人兽共患病的抗体水平,为下一步制定相应防控措施提供了参考。 相似文献

采集哈尔滨某猫舍中表现为上呼吸道感染的患病猫眼、鼻拭子，PCR初步确诊为猫杯状病毒(FCV)和猫疱疹病毒(FHV-1)混合感染。利用猫肾细胞(CRFK)对样本进行病毒分离，前两代细胞培养物的核酸检测结果为FHV-1和FCV阳性，第三代开始只有FCV阳性，由此分离出FCV。制备此株FCV的鼠源多克隆抗体，并中和混合培养物中的FCV,从而分离出FHV-1,命名为HRB2019株。通过病毒粒子形态观察、间接免疫荧光试验(IFA)和基因序列分析等方法鉴定HRB2019株，并研究其体外生长动力学。结果显示，HRB2019株可在CRFK细胞上产生典型病变，测得其第四代病毒滴度为1×108.43TCID50·mL-1;电镜下可观察到球形、有囊膜、直径约为200 nm的病毒粒子；IFA结果显示，分离株可与FHV-1阳性血清结合，出现特异性荧光；扩增分离株的gD基因，其与国内外流行株高度同源。病毒一步生长曲线表明，HRB2019株感染细胞12 h后开始复制增殖，12～36 h为快速增殖期，48～72 h进入增殖平台期且滴度达到高峰，84 ... 相似文献

Pancreatitis was considered a rare disease in the cat until a couple of decades ago when several retrospective studies of severe acute pancreatitis were published. It was apparent that few of the diagnostic tests of value in the dog were helpful in cats. With increasing clinical suspicion, availability of abdominal ultrasonography, and introduction of pancreas-specific blood tests of increasing utility, it is now accepted that acute pancreatitis is probably almost as common in cats as it is in dogs, although the etiology(s) remain more obscure. Pancreatitis in cats often co-exists with inflammatory bowel disease, less commonly with cholangitis, and sometimes with both. Additionally, pancreatitis may trigger hepatic lipidosis, while other diseases, such as diabetes mellitus, may be complicated by pancreatitis. Therapy is similar to that used in dogs, with added emphasis on early nutritional support to prevent hepatic lipidosis. Less is known about chronic pancreatitis than the acute form, but chronic pancreatitis is more common in cats than it is in dogs and may respond positively to treatment with corticosteroids. 相似文献

Cisplatin Toxicity in Cats 总被引：2，自引：1，他引：1
Deborah W. Knapp DVM Ralph C. Richardson DVM Dennis B. DeNicola DVM PhD Gerald G. Long DVM PhD William E. Blevins DVM MS 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1987,1(1):29-35
Cisplatin (cis-diamminedichloroplatinum; Platinol, Bristol, Syracuse, NY) was administered to 11 cats, divided into three groups of experimental and clinical patients. In group 1, cisplatin was administered at a dose of 60 mg/m2 to four cats. In an attempt to avoid renal toxicity, saline diuresis was induced by administering 0.9% saline solution intravenously at a rate of 20 ml/kg/hr for 4 hours before and 2 hours after cisplatin administration. All four cats became dyspneic and died 48-96 hours after cisplatin administration. Postmortem findings included severe hydrothorax, pulmonary edema, and mediastinal edema. In group 2, four experimental cats entered a trial comparing the effects of saline diuresis and cisplatin (60 mg/m2) with the effects of saline diuresis and placebo (0.9% saline solution). The cats in the saline control group remained completely normal, while the cats that received cisplatin developed clinical signs and gross postmortem pulmonary changes identical to those in the first group of cats. Histopathologic examination showed that the alveolar septa were thickened and congested, and contained macrophages, occasional neutrophils, thrombi, and small foci of necrosis and fibrin. Microangiopathic changes were seen in the alveolar capillaries. In the third group, three additional cats were treated with a lower dose of cisplatin. Two cats that received 40 mg/m2 of cisplatin developed pulmonary changes similar to, but less severe than, those seen in the cats that received the higher dose of cisplatin. One cat treated with 20 mg/m2 of cisplatin showed no pulmonary changes ante mortem or post mortem. This series of 11 clinical and experimental cases identifies an apparent species-specific, dose-related, primary pulmonary toxicity of cisplatin in cats. 相似文献

Acromegaly in 14 Cats 总被引：3，自引：0，他引：3

Acromegaly was diagnosed in 14 middle-aged to old cats of mixed breeding. Thirteen (93%) of the cats were male and one was female. The earliest clinical signs in the 14 cats included polyuria, polydipsia, polyphagia, all of which were associated with untreated diabetes mellitus. All developed severe insulin resistance within a few months; peak insulin dosages required to control severe hyperglycemia ranged from 20 to 130 U per day. Other clinical findings weeks to months after diagnosis included enlargement of one or more organs (e.g., liver, heart, kidneys, and tongue) (n = 14), cardiomyopathy (n = 13), increase in body size and weight gain (n = 8), nephropathy associated with azotemia and clinical signs of renal failure (n = 7), degenerative arthropathy (n = 6), and central nervous system signs (i.e., circling and seizures) caused by enlargement of the pituitary tumor (n = 2). The diagnosis of acromegaly was confirmed by demonstration of extremely high basal serum growth hormone concentrations (22 to 131 micrograms/l) in all cats. Computerized tomography disclosed a mass in the region of the pituitary gland and hypothalamus in five of the six cats in which it was performed. Two cats were treated by cobalt radiotherapy followed by administration of a somatostatin analogue (octreotide), whereas two cats were treated with octreotide alone. Treatment had little to no effect in decreasing serum GH concentrations in any of the cats. Eleven of the 14 cats were euthanized or died four to 42 months (median survival time, 20.5 months) after the onset of acromegaly because of renal failure (n = 2), congestive heart failure (n = 1), concomitant renal failure and congestive heart failure (n = 3), progressive neurologic signs (n = 2), persistent anorexia and lethargy of unknown cause (n = 1), the owner's unwillingness to treat the diabetes mellitus (n = 1), or unknown causes (n = 1). Results of necropsy examination in ten cats revealed a large pituitary acidophil adenoma (n = 10), marked left ventricular and septal hypertrophy (n = 7), dilated cardiomyopathy (n = 1), arthropathy affecting the shoulder, elbow, or stifle (n = 5), and glomerulopathy characterized by expansion of the mesangial matrix and variable periglomerular fibrosis (n = 10). 相似文献

Propofol was administered to forty nine cats to induce anaesthesia. The mean dose required was 6.8 mg/kg and this was not affected by prior administration of acepromazine maleate. In 27 cases, propofol was also used as the principal maintenance agent (mean dose rate 0.51 mg/kg/minute). Inductions were very smooth and problem free. Intubation was easily achieved in 15 cats with the aid of local desensitization by lignocaine spray or neuromuscular relaxation by suxamethonium. Heart rate did not vary significantly during induction or maintenance of anaesthesia but respiratory rates did fall significantly. 相似文献
