鹦鹉热(Psittacosis)又称鸟疫(Ornithosis),是由鹦鹉热衣原体(Chlamydia psittaci,简称Cp)引起的人、鸟共患的自然疫源性疾病。同时该病原体不仅侵及鹦鹉类,还可使鸡、鸭、鸽、火鸡等受染。该病也可以传染给人,人类多因接触鸟类或羽毛制品而感染,病程较长,反复发作或变为慢性病,是典型的动物源性传染病。家禽多为隐性感染,主要特征为结膜炎、鼻炎及腹泻。本病广泛分布于世界各地,我国20世纪60年代初期即证实有本病存在,一般呈散发,偶有小范围的暴发或流行。所以必须加强对鹦鹉热的防治。 相似文献

马、驴衣原体病是由鹦鹉热衣原体和沙眼衣原体引起的一类危害严重的自然疫源性人畜共患病。该病呈地方性流行,以流产和关节炎、结膜炎等多种炎症病型为主要特征,是造成云南畜牧业经济损失的主要病原。为了摸清易门县马、驴衣原体病的感染情况,以便提供有效防控措施,笔者于2013年9月至2014年2月,随机采取10份马血清和83份驴血清进行衣原体病血清学调查,结果如下。 相似文献

弓形虫病(Toxoplasmosis)是由真球虫目、肉孢子虫科、弓形虫亚科、弓形虫属刚第弓形虫(Toxo-plasma gondii)寄生在猪、牛、羊、猫等动物和人的有核细胞内所引起的一种人畜共患的自然疫源性原虫病,又称弓形体病、弓浆虫病。该病呈全球性分布,其宿主范围相当广泛,目前已知200多种动物可被感染[1]。据国外报道,全世界约有5亿~10亿人感染弓形虫病,人群平均感染率约25%~50%[2,3]。动物感染本病后多数不呈明显的临床症状。在肉用畜禽中,猪、牛、羊、鸡均可感染,但对猪易感性最高,致病力最强,具有高度致死性,如防治不当可引起暴发或成批死亡,危… 相似文献

钩端螺旋体病也称细螺旋体病,是一种重要而复杂的人畜共患病和自然疫源性传染病。在家畜中主要发生于猪,牛、犬、马、羊次之。临床表现形式多样,大多数呈隐性感染,少数急性病例表现发热、黄疸、血红蛋白尿、贫血、水肿、流产、出血性素质、皮肤和粘膜坏死等特征。钩端螺旋体病的病原是一类形态相似、抗原性和遗传性各异,细小、能运动、需氧且有致病性的钩端螺旋体。1临床症状绝大多数猪无明显临床症状,小仔猪和怀孕母猪最有可能遭受临床感染,一般潜伏期在2~20d。亚临床型是大多数猪所表现的形式,主要见于集约化饲养的育肥猪,通常有轻微或不… 相似文献

Behavior and behavior-associated issues are an important part of psittacine medicine. However, many veterinarians have an approach to parrots from the basics of handling and restraint to their assessment of behavioral issues (e.g., feather plucking), that fails to take into account the importance of understanding a bird’s natural behavior in the wild, and how these actions can be adapted to optimize interactions between the bird and their human owners. Understanding how to influence parrot behavior by positive reinforcement rather than punishment is key to improving the welfare of these captive birds and their owners. 相似文献

2007年12月~2008年8月,通过进行笼内环境生态化布置、改变食物投喂方式、投放玩具等方式,对上海动物园葵花凤头鹦鹉实施了丰容试验,并通过对3只葵花凤头鹦鹉的行为观察进行了丰容效果的评价。结果表明:丰容促进了鹦鹉身体各部位协调性;休息行为减少,活动行为增加;异常行为减少;丰容区域利用率大于非丰容区。针对动物园鹦鹉饲养中存在的一些问题,本文提出了几点建议:保证视线无障碍设施的防撞、防逃逸、通风、保洁'加强饲养员的专业知识培训和责任性教育i针对不同物种采取不同丰容方式并定期维护及更换丰容设施;经常开展国际交流,提升丰容水平等。 相似文献

Behavior modification training, like veterinary medicine, is an exacting science, requiring a knowledge of not only wild avian behavior, but of child and adult human behavior as well. It is important to note that absolutely any changes in a bird's or its owner's environment may trigger a vast assortment undesirable behaviors. Some behavior problems are simple, but most have multiple causes and each of those causes must be determined and corrected before a high rate of success is evident. As in veterinary medicine, some birds respond to general "shotgun" techniques; however, parrots are intelligent and complex creatures. They consider themselves an integral part of their human "flock" and respond as such. Most commonly seen negative behaviors can be altered, at least to some extent, and, in most cases, they can be alleviated completely. Yelling at the bird, striking it, or any other type of confrontational behavior modification technique is virtually useless and can actually worsen most situations. A high percentage of success involves extensive history taking, an understanding of human and wild animal flock behavior, and the time to create a complete program for each individual and its owner. 相似文献
