犬细小病毒病发病情况调查与流行分析 总被引：1，自引：0，他引：1
对吉林市2009—2010年犬细小病毒病的发病情况进行了调查和分析。收集9个动物医院2年接诊的5684例疑似犬细小病毒病犬,通过临床检查及实验室诊断,确诊4124例患犬发生不同类型的犬细小病毒病。研究表明,本病发生多以肠炎型为主,占总发病数的49.64%;犬品种影响犬细小病毒病的发生,纯种犬的发病率最高,占62.85%,土种犬发病率最低,占11.99%;1~3月龄的幼犬多发,占发病数的65.11%;一年四季均有发病,多发于气温骤变的11~12月和2~3月;免疫次数也影响了犬细小病毒病的发生,每年2次免疫可以显著降低犬细小病毒病的发生。因此,选择高质量的疫苗,增加免疫次数,选择合理的饲养环境,加强多发季节和多发年龄段对犬的保护是减少本病发生的关键。 相似文献

在众多犬疾病中,犬细小病毒病是威胁犬群生命安全的最主要流行病之一.本人对秦皇岛康健宠物医院和昌黎爱康宠物医院2014年1~12月诊治的共317例犬细小病毒病例,就其发病及治疗情况做以调查,以了解犬细小病毒病的流行现状.结果显示:犬细小病毒感染发病急,病程短,对6月龄以下幼犬危害更大,国内报道该病的发病率为90%,死亡率为50.7~66.7%,本病主要发生在6月龄以下幼犬,冬季发病较多,其次为初春或深秋,夏季发病较少.疫苗对该病的防治有一定的效果,由于养犬密度、动物的流行性不断加大及种种原因导致的免疫失败,本病在临床仍居犬病之首. 相似文献

犬细小病毒病的流行现状调查 总被引：3，自引：0，他引：3
对犬细小病毒病流行现状进行调查,为本病的预防、诊断和治疗提供依据。 用犬细小病毒抗原检测试剂盒对2008年门诊的具有腹泻、呕吐、粪便带血等体征的189只患犬作病原检测,对犬细小病毒阳性病例兼有发热、咳嗽体征的16例病犬同时作犬瘟热病毒抗原检测。结果犬细小病毒阳性病例共137只,发病年龄从1个月～15岁各年龄段均有分布,以6月龄以下幼龄动物发病较多,占65.7%。流行季节差异不大,以春季病例略多,占27.0%。犬细小病毒与犬瘟热病毒混合感染的有12例,占8.8%。对在疫苗接种免疫保护期内的4只患犬进行检测,3只犬细小病毒阳性。结论：①免疫力尚未建立是幼犬发病的主要原因;②不按规定的免疫程序对动物进行加强免疫是成年犬发病的主要原因;③在部分发病幼犬中存在犬细小病毒与犬瘟热病毒的混合感染;④老龄动物对免疫的应答能力下降可导致免疫失败。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献
