Effects of three methods of restraint an in rhesus and african green monkeys intravenous glucose tolerance testing

The intravenous administration of 0.75 gm glucose per kg and the measurement of serum glucose pretest and at 10, 20, 30, 60, 90 and 120 minutes constitute a satisfactory protocol for intravenous glucose tolerance testing of Rhesus (Macaca mulatto) and African Green (Cercopithecus aethiops) monkeys. No significant differences were noted between animals restrained with ketamine hydrochloride and those restrained with sodium pentobarbital, but the African Green males and females and the male Rhesus monkeys yielded significantly different results while being manually restrained.

非洲猪瘟疫情背景下兽医公共卫生学课程的教学策略

兽医公共卫生学是利用一切与人类和动物健康问题有关的理论知识、实践活动和物资资源,为人类健康事业服务的一门综合性应用学科,在动物性食品安全、动物疫病及人兽共患病方面发挥着重要的防线作用。针对当前我国发生的非洲猪瘟疫情,在阐述兽医公共卫生学重要性的基础上,分析了兽医公共卫生学课程的教学策略,以期打破对兽医专业认识的局限性,强化理解兽医公共卫生的意义,提升兽医公共卫生学的课程价值,并为优化教学内容、提高教学质量提供指导。     

The importance of manual white blood cell differential counts and platelet estimates in elephant hematology: blood film review is essential

Unique features of elephant hematology are known challenges in analytical methodology like two types of monocytes typical for members of the Order Afrotheria and platelet counts of the comparatively small elephant platelet. To investigate WBC differential and platelet data generated by an impedance-based hematology analyzer without availability of validated species-specific software for recognition of elephant WBCs and platelets, compared to manual blood film review. Blood samples preserved in ethylenediaminetetraacetic acid (EDTA) of 50 elephants (n = 35 Elephas maximus and n = 15 Loxodonta africana) were used. A Mann-Whitney test for independent samples was used to compare parameters between methods and agreement was tested using Bland-Altman bias plots. All hematological variables, including absolute numbers of heterophils, lymphocytes, monocytes, eosinophils, basophils, and platelets, were significantly different (p < 0.0001) between both methods of analysis, and there was no agreement using Bland-Altman bias plots. Manual review consistently produced higher heterophil and monocyte counts as well as platelet estimates, while the automated analyzer produced higher lymphocyte, eosinophil, and basophil counts. The hematology analyzer did not properly differentiate elephant lymphocytes and monocytes, and did not accurately count elephant platelets. These findings emphasize the importance of manual blood film review as part of elephant complete blood counts in both clinical and research settings and as a basis for the development of hematological reference intervals.     

浅谈非洲猪瘟生物安全防控策略

非洲猪瘟是猪的一种急性、烈性传染病,一旦发病,致死率达100%,会给整个养猪业和社会经济造成巨大损失,目前尚没有效疫苗和特效治疗药物,因此非洲猪瘟的生物安全防控对于预防该病的发生具有重要意义。文章从非洲猪瘟的病原学特点流行现状、诊断方法、疫苗研制和生物安全防控要点等几方面进行叙述,旨在为该病的生物安全防控提供一定的理论参考价值。     

猪场生物安全体系中十个通道的设计应用

2018年8月开始,非洲猪瘟在我国快速多点发生,该病是高度接触性传染性疾病,目前无有效的疫苗和药物控制,各大公司和养殖户开始了猪场生物安全体系的升级改造。两年后我国大部分猪场的成功复产,全国生猪出栏量的大幅提升,证明了生物安全措施巨大效力;同时在严格的生物安全措施下创新了精准剔除、快速复产等操作,进一步证明了生物安全措施的有效作用。文章主要介绍猪场生物安全体系中入口(大门)和出口(后门)最为关键防线处的通道设计,方便所有的生物安全操作能够高效落实,切断病原轻易进出猪场的途径。

规模化猪场非洲猪瘟防控

非洲猪瘟疫情已经成为制约养猪业发展的头号杀手,生猪稳产保供任务引起高度重视,因此,防控非洲猪瘟疫情是各级政府和养猪企业的重点工作之一,该文主要论述规模化猪场非洲猪瘟防控措施。     

非洲猪瘟疫情防控难点与对策

目前肉制品的健康情况备受人们关注,而猪肉是人们餐桌上必不可少的肉制品之一,猪只的安全饲养对人类的生命健康有重要的影响。在饲养猪只中,可发生多种传染病,其中最主要的一种是非洲猪瘟,该传染病不仅具有高热性的特点,还具有高度接触性的特点,再加上目前对于该种疾病还没有特效的疫苗,以及有效的治疗措施,因此,做好该种疾病的预防工作至关重要。该文主要论述非洲猪瘟进行论述,并制定相应的防控措施。为减少猪只发病几率奠定良好的基础。
