黑叶猴群发附红细胞体病

<正>黑叶猴是目前国内动物园常见的珍稀灵长类观赏动物之一,其头顶有黑色直立的毛冠,两颊至耳基部有白毛,成体全身乌黑色,所以又称乌猿或乌叶猴,目前仅产于广西、贵州,分布区域狭窄,数量很少。附红细胞体病是由附红细胞体寄生于动物红细胞表面及血浆中引起动物发生高热、贫血、黄疸为主要症状的一种传染病。该病一般发生于每年的5—9月份,主要传播途径有接触性、血源性、垂直性及吸血媒介昆虫,该病在家畜中多发于猪、牛、羊、兔、犬     

马附红细胞体病的诊治

附红细胞体病是由附红细胞体寄生于人和动物红细胞表面或游离在血浆中引起的一种以贫血、黄疸、发热为主要特征的人兽共患病.近年,猪附红细胞体病发生和流行呈上升趋势,牛、羊发病也有报道,但马发生附红细胞体病还鲜有报道.     

一起猪群发附红细胞体病的警示

猪附红细胞体病并不是一种新病，早在1932年印度就有报道，但一直未受到关注。近几年，该病有蔓延增多的趋势，在全国许多地区，特别是养猪密集地区的发生与流行较为广泛。该病的主要特征是贫血、黄疸和发热。其危害性是引起母猪繁殖力下降、猪只生产性能降低以致死亡，给养猪业所带来的经济损失较为严重。     

附红细胞体及附红细胞体病

附红细胞体病（Eperythrozoonosis）是由寄生于血液内的原核生物——附红细胞体（Eperythrozoon）引起的，以溶血性贫血、黄疸、发热为主要特征的人兽共患病。临床上该病又被称为“黄疸性贫血病”、“类兽体病”、“猪红皮病”等。附红细胞体病在国外的流行报道较少，但该病对我国的畜牧生产及人民健康都已造成了严重的威胁，在局部地区已呈暴发流行的趋势。从目前的流行病学来看，人、各种动物和鱼以及禽类都可有附红细胞体病原感染或寄生。大多数动物感染后呈慢性带菌，临床上以贫血为主要症状。近年来，该病在我国有不断扩大流行的趋势，从各种家畜到人都有大量感染的报道。在某些局部地区已成为家畜（尤其是仔猪和犊牛）大批死亡的主要原因。尽管对感染人的病原还没有准确定位，但由于该病主要常见于动物养殖业者，因此附红细胞体病很可能是一类尚未引起人类重视，但具有潜在威胁的新发人兽共患病。目前，国内外对附红细胞体病的研究尚不深入，尤其在国内，对该病的认识还一直停留在临床诊断方面。为了制定有效的控制和预防措施，减少危害，有必要开展对附红细胞体病及病原的更为深入的基础研究。     

附红细胞体病

世界上对附红细胞体病的研究大约起于 2 0世纪 2 0年代。而我国对此病的研究较晚 ,1 981年以后才相继出现有关畜禽及人体感染附红细胞体病的报道。 2 0 0 2年 8月在大连市甘井子区某养猪场由于注射猪瘟疫苗时违规操作又爆发了猪附红细胞体病 ,造成一百多头猪死亡。由于此病对畜牧经济的影响很大 ,也严重危害人体健康 ,这种人畜共患传染病已逐渐引起畜牧界及卫生界的关注。1　附红细胞体的研究附红细胞体病是由附红细胞体感染而引起的人畜共患传染病。附红细胞体 (简称附红体 )为立克次体目血虫体属微生物 ,寄生于红细胞表面、血浆及骨髓中。…

Equine strongyles II. Occurrence of anthelmintic resistance in Switzerland

The occurrence of anthelmintic resistance in strongyles was investigated in 440 horses on 90 farms in Switzerland. The egg hatch assay suggested that benzimidazole (BZ)-resistance was present in 40 of 82 farms (49%). Faecal egg count reduction after pyrantel-treatment was above 96% in 14 of 15 farms. In the remaining farm the efficacy was only 80%. Ivermectin efficacy was investigated on 5 farms and the efficacy was recorded at 98-100%. Faecal cultures undertaken after treatment revealed almost exclusively larvae of the family Cyathostominae. Data about management practices, pasture hygiene and anthelmintic usage were obtained with a questionnaire. Horses were treated on average 3.5 times per year. In 75% of the farms BZ were a component of the seasonal treatment schedule. Only the use of BZ had a significant correlation with the presence of BZ-resistance (P < 0.01). Recommendations for the control of equine strongyles should include measures that minimize the risk of resistance developing against remaining effective anthelmintics.     

Perception of Equine Practitioners Regarding the Occurrence of Selected Equine Neurologic Diseases in the Northeast Over a 10-Year Period

A survey was developed to examine the perception of equine practitioners regarding the occurrence of five equine neurologic diseases in the northeastern United States over the 10-year period between June 1, 1997 and June 1, 2007. This information was then compared with trends at Cornell University's Equine Hospital during the same time span, which in general agreed with practitioners' opinions. Equine herpes virus-1 (EHV-1) neurologic disease, equine motor neuron disease (EMND), and equine protozoal myelitis (EPM) have historic and current relevance. Results showed that the frequency of EMND and EPM has remained relatively stationary or decreased somewhat, whereas the frequency of the neurologic strain of EHV-1 may have increased slightly over the last decade. Less historical information on clinical disease associated with Borrelia burgdorferi infection (Lyme disease) and Parelaphostrongylus tenuis exists; however, results suggest that P. tenuis in the equine is presently emergent. Opinions regarding the existence and rate of occurrence of clinical borreliosis in horses appear divided. A better understanding of the frequency with which these diseases occur, as well as possible associated positive risk factors, will aid the equine practitioner in making an appropriate diagnosis in cases of neurologic disease in their equine patients.     

Occurrence of Equine Coital Exanthema in Mares from an Embryo Transfer Center

Equine coital exanthema (ECE) is an acute, venereal disease caused by equid herpesvirus 3 (EHV-3), characterized by the formation of papules, vesicles, pustules, and ulcers on the vaginal and vestibular mucosa as well as on the skin of the penis, prepuce, and perineal region of mares and stallions. The present work describes an outbreak of ECE characterized by typical lesions around the anus and on the perineal skin, discomfort, and anorectal lymphadenopathy, which occurred in a large number of donor and recipient mares at an embryo transfer center in Argentina. We found that the horses' movement pattern, the environmental conditions, and the management procedures could have favored the introduction and/or reactivation from latency and spread of EHV-3. Although this is the first report of an outbreak of ECE in an embryo transfer facility, it reinforces the need to introduce additional hygienic and preventive measures to avoid EHV-3 spread and future ECE outbreaks.

全球马流感发生的风险状况研究

目的开展在全球尺度上的马流行性感冒(马流感)发生状况的分析。方法基于数据挖掘方法,借鉴地理风险分析和Kolmogorov-Smirnov统计检验的方法,开展对全球马流感发生态势的分析。结果统计分析认为:(1)全球马流感近十年以来发生涉及范围和区域扩大,发病数量增多,发病频次高,发病态势严重。(2)全球马流感发生的区域特征显著,美洲和欧洲是全球马流感发病态势比较严重的区域,而亚洲相对较美欧的发病态势为弱。(3)在近十年以来,全球尺度上马流感的发生在空间和时间上保持较强的连续性和比较平稳的发展态势,但局部时段的马流感的发生呈现较大的跳跃性。结论美洲和欧洲是目前马流行性感冒发生和流行的主要区域,从该区域输入马匹等马属动物及其产品会带来一定的释放风险.
