Comparison of the Standard AGID Test and Competitive ELISA for Detecting Bluetongue Virus Antibodies in Camels in Gujarat,India     

Chandel BS  Chauhan HC  Kher HN 《Tropical animal health and production》2003,35(2):99-104

The performance of the standard agar gel immunodiffusion (AGID) test and the competitive enzyme-linked immunosorbent assay (cELISA) for the detection of serum antibody against bluetongue virus (BTV) in clinically healthy and diseased camels in Gujarat state were compared. Out of 176 sera tested, 22 (12.5%) and 34 (19.3%) were positive for group-specific bluetongue antibodies by AGID and cELISA, respectively. Maximum seropositivities of 18.0% by AGID and 25.8% by cELISA were recorded in the Kutchhi breed, and of 6.9% and 12.6%, respectively, in the Marwari breed. The seroprevalence detected by AGID and cELISA in clinically healthy and diseased camels did not differ significantly with regard to bluetongue disease in these breeds.  相似文献   

The Arterial Supply of the Metacarpophalangeal Joint in the Bactrian Camel (Camelus bactrianus)     

Wang  Jianlin  Cuisheng 《Veterinary research communications》1998,22(6):365-372

The arterial supply of the six metacarpophalangeal joints was studied in Bactrian camels. The arterial branches supplying the metacarpophalangeal joints were derived from the metacarpal distal perforating, medial and lateral branches of the palmar metacarpal artery III, medial and lateral branches of the palmar common digital artery III and the abaxial palmar proper digital arteries III and IV. These arterial branches were the proximal dorsoaxial distal metacarpal, distal dorsoaxial distal metacarpal, abaxial distal metacarpal, palmar distal metacarpal, interosseous distal metacarpal, dorsoaxial proximal proximal phalangeal, palmoaxial proximal proximal phalangeal, palmoabaxial proximal proximal phalangeal and dorsoabaxial proximal proximal phalangeal branches. They linked with each other around the metacarpophalangeal joint.  相似文献   

双峰驼髋关节解剖特征   总被引：2，自引：0，他引：2  

孟昭权  谢铮铭 《中国兽医学报》1998,18(5):510-511

运用大体解剖学方法,结合活体Ｘ射线透视及光学摄影术,观察了双峰驼的髋关节。与马、牛、羊、猪、犬及人的对等器官比,双峰驼的髋关节囊纤维层增厚,形成髂股、坐股及耻股３条韧带,分别类似于人的同名韧带;关节囊纤维层有少量弓形及半环形纤维,但未形成轮匝带;股骨头韧带始于髋臼切迹及髋臼窝,与人（始于髋臼横韧带及髋臼切迹两侧）、马（始于近髋臼切迹的耻骨下沟）均不同;髋关节无副韧带（与牛同）。  相似文献

内蒙古阿拉善盟双峰驼驼乳理化性质研究   总被引：2，自引：0，他引：2  

赵电波  吉日木图  刘红霞  邵亚东  张和平 《乳业科学与技术》2005,27(3):112-117

本文研究了10峰内蒙古阿拉善盟双峰驼不同泌乳时间驼乳的一般理化性质。其比重及pH值与已有报道的单峰驼驼乳结果基本一致,而酸度(%)高于单峰驼。电导率与乳中Na+、K+和Cl-含量之和有关,随三者之和的增减而增减。驼乳的蛋白质、脂肪、乳糖、干物质、灰分和钙的含量均高于牛乳,磷的含量比牛乳略低。驼乳的缓冲性与牛乳有差异:当乳样先酸化后用碱回滴时,驼乳和牛乳分别在pH4.4～6.6和pH5.0～6.6范围内出现典型的“弧形线”,驼乳的最大缓冲作用发生在pH近似4.4处,牛乳的最大缓冲作用在pH近似5.1处,但驼乳在pH4.9处仍有一个缓冲峰。双峰驼驼乳的酒精稳定性(75±2.0)%稍低于牛乳的酒精稳定性(77±1.0)%,驼乳与牛乳的酒精稳定性的变化趋势基本一致,加入Na+、K+都引起酒精稳定性降低,游离Ca2+浓度的降低或pH值的上升都会导致酒精稳定性的增加。  相似文献   

Random Amplification of Polymorphic DNA Fingerprinting of Trypanosoma evansi     

Basagoudanavar  S.H.  Rao  J.R.  Singh  R.K.  Butchaiah  G. 《Veterinary research communications》1999,23(4):249-255

The total genomic DNAs from Trypanosoma evansi isolates of bubaline, equine and cameline origin were amplified by polymerase chain reaction using eight arbitrarily selected 10-base primers. Informative band patterns were obtained for all isolates analysed. Depending upon the T. evansi isolate–primer combination, between 1 and 11 reproducible DNA fingerprints of 205 to 3016 bp were amplified, suggesting minor and major differences in their RAPD (random amplified polymorphic DNA) profiles.  相似文献

何静  李国伟  海勒  吉日木图 《西北农业学报》2019,28(11):1750-1759

旨在从双峰驼粪便中筛选能够分解纤维素的菌株,并对分离菌株进行鉴定和酶学特性分析。采用羧甲基纤维素平板法初筛和摇瓶发酵法复筛,从双峰驼粪便中分离筛选到1株能够降解纤维素的纤维素分解菌;采用形态学观察、生理生化特性以及16S rRNA基因序列同源性分析,初步鉴定该菌株为纤维化纤维微菌(Cellulosimicrobium cellulans)。根据该菌株的产酶特性评定其产酶能力;从其发酵产纤维素酶的适宜pH、温度、时间和接种量来评价该菌株的酶学特性。结果显示,该菌株最适酶反应条件为50℃,pH为6.0,且该菌株产生的纤维素酶具有较好的热稳定性。该菌株的最佳产酶条件为接种量10%,初始pH为7.0,培养温度为30℃,发酵时间为72 h。所筛选菌株产生的酶具有一定的耐碱性和耐热性,可应用于食品行业或废料处理等方面。  相似文献

The anatomy of the atrioventricular bundle in the heart of camels (Camelus dromedarius)     

S. R. Ghazi  M. Tadjalli 《Veterinary research communications》1993,17(6):411-416

The anatomy and histology of the atrioventricular bundle (AVB) was studied in the heart of six camels (Camelus dromedarius). The trunk of the atrioventricular bundle (bundle of His) was a direct continuation of the atrioventricular (AV) node with no sharp line of demarcation between the node and the bundle. The atrioventricular bundle ran through the fibrous trigone and entered the lower part of the interventricular membranous septum, beneath the right endocardium, then lay over or slightly to the side of the centre of the muscular interventricular crest. The AVB of camels measured 4.12±1.00 mm in length, 3.66±1.13 mm in width and 1.13±1.85 mm in thickness, its maximum sectional area being 12.68±6.13 mm².Histologically, the AVB in the heart of camels comprised multiple strands of Purkinje cells separated by collagen fibres and surrounded by connective tissue. It resembled that in human beings and dogs except that, in camels, intercalated discs were present at the intercellular connections in the AVB.Abbreviations AVB trunk of the atrioventricular bundle - AV node atrioventricular node  相似文献   

双峰驼肝脏弥漫性脂肪瘤的发现及其与微量元素关系的探讨     

马卓  刘宗平  陈怀涛  杨德兵 《畜牧兽医学报》1995,(1)

１９９１～１９９２年，在内蒙古阿拉善右旗和甘肃省民勤县双峰驼肝脏发现一种罕见的脂肪瘤。眼观，这种脂肪瘤呈大小不一的结节状，弥漫分布于整个肝脏。镜下，它由成熟的脂肪细胞和少量纤维结缔组织构成，其间夹杂变性、坏死的肝细胞。流行病学调查表明，该肿瘤主要发生于荒漠和半荒漠草原全年放牧的双峰驼，发病率高达２７．６％。病变肝组织的元素分析发现，Ｃｕ含量明显降低，且Ｆｅ与Ｃｕ含量呈强负直线相关（ｒ＝－０．７１０），表明该肿瘤的发生与低Ｃｕ有关，这种低铜可能是由于高Ｆｅ所引起的。  相似文献
