正一、我国临床常见流行猪病的分类目前我国临床常见猪病主要有三大类,即:呼吸系统疾病、消化系统疾病和繁殖障碍性疾病。猪群三大系统疾病表现形式多样,病原复杂,主要呼吸系统疾病主要由病毒、细菌、寄生虫和肺炎支原体引起。消化系统疾病则主要由病毒、细菌、寄生虫引起。繁殖障碍性疾病则主要由病毒、寄生虫引 相似文献

中国动物园圈养鹤类现状调查及分析 总被引:1,自引:0,他引:1
报道了中国动物园协会主要饲养鹤类会员单位的鹤类调查结果,目的是更好地了解中国动物园圈养鹤类的种群数量及目前会员单位鹤类饲养管理的现状、存在的问题与相关需求,从而提高鹤类饲养管理水平,最终形成健康的、可持续发展的种群。本调查于2011年8月向中国动物园协会120家会员单位发出了调查问卷,截止到2011年10月11日共收到中国动物园协会主要饲养鹤类的56家会员单位(包括动物园、野生动物园与自然保护区)的回复(回收率为46.7%)。在回复的56家单位中共饲养鹤类12种1 836只(8只杂交鹤除外)。种群数量比1997年增加了58.4%。近一半的单位认为饲养设施处于一般水平。近80%的鹤类向游客展出,并且大部分都采用成群饲养的展出方式。有85%的单位能够实现个体识别,更多的单位选择脚环和芯片标识鹤类。在人工育雏过程中,雏鹤的腿病和由于混养引起打斗而造成的外伤是存在的主要问题。疾病是造成全国圈养鹤类死亡的主要原因,其次是由于外伤造成骨折引起的死亡。各会员单位希望今后能够开展鹤类性别鉴定、人工育雏、人工授精的培训。根据本次调查结果,提出了8项建议。 相似文献

中国鹤类动物发生疾病统计分析 总被引:2,自引:0,他引:2
依据已有文献资料记载,分析了中国近25a来鹤类动物发生的疾病。丹项鹤、白鹤、黑颈鹤、白枕鹤、灰鹤、蓝鹤、蓑羽鹤、白头鹤,共8种鹤有发病资料,丹项鹤疾病占统计总数的64.12%。营养因素、寄生虫、细菌是引起鹤发病的主要原因,有机磷中毒是造成野生鹤大批死亡的主要原因,球虫病、血液原虫病是造成圈养鹤大批死亡的主要疾病。幼鹤腿部疾病和痛风是主要的营养性疾病,吸虫、球虫、住白细胞原虫是导致发病主要的寄生虫,巴氏杆菌、大肠杆菌是引起发病的主要细菌,有机磷是造成中毒的主要原因,新城疫病毒、马立克病毒、疱疹病毒亦可引起鹤发病。加强饲养管理与合作,改善环境条件,提高饲养人员的业务素质,完善保护法律和落实措施,是减少疾病发生和死亡有效措施。 相似文献

2011年秋季,浙江省淳安县的桑园大面积发生一种罕见的桑叶特大病斑病害。病叶呈现菌核病的典型症状:叶面形成灰褐色轮纹水渍状病斑,病斑随着病情发展以同心圆状向外延伸,颜色由里到外逐渐变深;叶背的灰色圆形病斑可见多个同心圆形绒毛状菌丝体和分生孢子。病斑与病斑外的部分组织以及病斑同心圆上的绒毛状组织于光学显微镜下可观察到菌丝体与分生孢子形态,病斑边缘组织块在PDA培养基上分离培养的病原菌都可观察到菌丝体形成的菌核。依据以上症状和病原真菌分离培养的形态特征,初步诊断该病为桑叶菌核病,病原为富克尔核盘菌[Sclerotinia fuckeliana(de Bary)Fuck.]。调查16个样点的480株桑树,株发病率为81.25%,叶发病率为37.63%,发病指数18.5。9~10月份气温24.4~18.7℃,多阴雨天,加之连片桑园通风透光能力较弱且相对湿度较大的环境条件,病原菌繁衍迅速,病害呈流行之势。尚未发现有明显抗性的桑树品种。 相似文献

牙周病(periodontal disease,PD)是由细菌在牙齿表面聚集形成的牙菌斑和牙结石逐渐侵蚀牙周组织,引发周围组织炎症的一类疾病。根据疾病的发展进程,可分为齿龈炎与牙周炎2个阶段。在小动物临床疾病中牙周病尤为常见,世界范围内约有80%的成年犬患有该病。由于饲主对于犬的口腔保健意识薄弱且该疾病隐秘性较高,患犬就诊时往往已出现牙周支持组织不可逆的损伤,细菌及其毒力因子通过血液循环进入全身从而引发系统性疾病的风险大大提高。但目前犬牙周病的核心致病菌属、菌群失调的原因与发病机制尚不明确。因此,笔者基于高通量测序方法的病原学研究结果,分析与疾病发展相关的微生物群。同时,整合目前世界通用的最新犬牙周病临床诊断分级标准及犬牙周病的中西医防治方案,分析犬牙周病与全身系统性疾病之间的相关性,系统综述犬牙周病在国内外小动物临床领域的研究进展,以期为该类疾病的临床诊疗提供理论参考,推进兽医师在临床实践中更高效地开展该类疾病的诊疗工作,并为犬牙周病相关的临床研究提供思路。 相似文献

From 1980 to 1988 235 koalas were necropsied and 67 were found to have urinary tract disease. Six affected koalas out of 48 were derived from wildlife parks around Sydney while 61 of 187 were derived from free living populations on the central and north coasts of New South Wales. Sixteen had cystitis alone, 5 had cystitis and associated renal disease only, 16 females had cystitis with genital disease, 23 had urinary disease in combination with other systemic disease and 7 had renal disease only. Overall 49 animals had cystitis (30 females and 19 males; 47 being free living) with 12 of these having renal extension (all free living). Cystitis tended to be active but chronic while associated renal disease was mainly designated as hydronephrosis and pyelonephritis. Other forms of renal disease included lymphosarcoma, oxalate nephrosis, acute and chronic nephritis, and microabscessation related to septicaemia. Female genital disease associated with cystitis was commonly vaginitis and metritis. Paraovarian cysts were detected with and without metritis. Other diseases occurring with urinary tract disease included conjunctivitis, dermatitis/stomatitis, pneumonia and hepatic disease. The higher prevalence of urinary tract disease in free living koalas, especially cystitis, is in contrast to captive koalas and may reflect the interaction between disease cause and habitat. 相似文献

BACKGROUND: Sinonasal disease is common in cats; chronic inflammatory disease and neoplasia are diagnosed most frequently. Radiographic and computed tomographic (CT) findings in nasal disease have been reported, although involvement of other cranial structures has not been fully described to our knowledge. HYPOTHESIS: We hypothesized that neoplastic or inflammatory obstruction of the auditory tube associated with sinonasal disease could result in CT evidence of effusive bulla disease in affected cats. ANIMALS: 46 cats with sinonasal disease, 18 control cats. METHODS: CT images acquired in cats with (n = 46) and without (n = 18) sinonasal disease were reviewed for evidence of concurrent bulla effusion. CT findings of soft tissue or fluid opacity within the tympanic bulla or thickening of the bone of the bullae were considered evidence of effusive bulla disease. RESULTS: The prevalence of bulla effusion in cats with sinonasal disease was 28% (13/46) and was significantly higher than that observed in cats without sinonasal disease (1/18, P = .043). CT findings that were found in association with effusive bulla disease included imaging features of sinusitis and nasopharyngeal disease. The most common neoplasm associated with bulla effusion was nasopharyngeal lymphoma. Bulla effusion was not observed in any cat with nasal carcinoma. CONCLUSIONS AND CLINICAL IMPORTANCE: Findings of this study suggest that auditory canal dysfunction may play a larger role in feline sinonasal disease than was previously recognized. The implications of these findings for management of cats with chronic inflammatory or neoplastic sinonasal disease require further investigation. 相似文献

Complex interactions between Chlamydia pecorum infection, the immune response and disease exist in the koala. We used quantitative polymerase chain reaction to investigate the relationship between C. pecorum infectious load and ocular and urogenital tract disease. Chlamydia pecorum shedding was generally higher in animals with chronic, active disease than in animals with inactive disease. The absence of ocular disease was generally associated with low levels of shedding, but relatively high levels of shedding in the urogenital tract were detected in some koalas without clinical disease signs. These results suggest a complex disease pathogenesis and clinical course in C. pecorum-infected koalas. 相似文献

牛结节性皮肤病是一种急性、亚急性传染性疾病。由于养殖户不科学地引种行为,造成该类疾病从其他国家引入本地区。牛结节性皮肤病又被称为牛结节疹、牛结节性皮炎或者牛疙瘩皮肤病,是由结节性皮肤病毒引发的一种急性亚急性传染性疾病。该类疾病被世界动物卫生组织规定为必须通报的疾病,我国将其划归为一类重大动物疫病。牛结节性皮肤病首先发生于新疆地区,随后由于不科学的运输和引种造成该类疾病,呈现逐渐扩大蔓延的趋势,带来的损失十分严重。需要掌握牛结节性皮肤病的具体流行特点、临床表现,做到及时发现及时处置,控制疫情的传播蔓延,确保我国牛养殖安全。该文主要论述牛结节性普皮肤病的诊断和防控。 相似文献
