Tetanus in a Camel (Camelus dromedarius) – A Case Report     

Wernery U  Ul-Haq A  Joseph M  Kinne J 《Tropical animal health and production》2004,36(3):217-224

Twenty days after an open castration, a 5-year-old dromedary was presented to the Dubai Camel Hospital with severe central nervous symptoms. The dromedary showed the following signs: off feed, stiff gait with extended neck, external swelling of the preputial sheath and groin region, and foamy saliva drooling from the mouth. The dromedary was unable to swallow. Three days after admission, the camel developed lockjaw, and on the fifth day it was unable to stand owing to paralysis of the hindquarters. Because of the severity of the disease and because it did not respond to treatment, the camel was euthanized 26 days after the operation and submitted to the Central Veterinary Research Laboratory for further investigation. Both castration wounds were closed and spermiducts were filled with necrotic masses from which Clostridium tetani was isolated. Two mice, which were injected with the filtrate of the thioglycolate broth, developed typical signs of tetanic spasm of the hind leg. Faecal samples from camel and horse paddocks that were only 50 metres apart were negative for C. tetani. However, C. tetani was isolated from two soil samples of the horse paddock. It is recommended that camels should be vaccinated against tetanus prior to castration.  相似文献   

Species of Ticks on Camels and Their Seasonal Population Dynamics in Eastern Ethiopia     

Zeleke M  Bekele T 《Tropical animal health and production》2004,36(3):225-231

A study was conducted to identify the species of ticks found on camels (Camelus dromedarius) and their seasonal population dynamics in Eastern Ethiopia. Collection and identification of the ticks were undertaken at 2-month intervals from December 1997 to August 1999. On each occasion, all the visible adult ticks were collected from one side of the body of each of the same 17 camels. The most abundant species of ticks on the camels were Rhipiephalus pulchellus (85.2%), Hyalomma dromedarii (5.9%), Amblyomma gemma (4.0%) and Amblyomma variegatum (1.8%). The average tick load per camel was higher during rainy months than during dry months. The smallest number of ticks per camel was observed during the driest month (December), whereas the highest was recorded in the wettest month (August). Any strategy intended to mitigate problems of tick infestation of camels in this area should take into account the identified tick species and their season of abundance.  相似文献   

The Zinc and Copper Content of the Plasma of Sudanese Camels (Camelus dromedarius)     

Mohamed HE 《Veterinary research communications》2004,28(5):359-363

A study was undertaken to investigate the variations in the content of zinc and copper in the plasma of Sudanese camels (Camelus dromedarius). A total of 993 Arabi camels, aged 0.5-8 years, were used to assess the effect of season, age, sex and physiological status on the plasma concentrations of copper and zinc. There was an increase in the concentration of Cu and a decrease in the concentration of Zn in the plasma with age. The concentrations of both Cu and Zn in the plasma were higher in the rainy season than in the dry season. The plasma copper concentrations in pregnant, low-lactating and high-lactating camels were 81.3 +/- 4.7, 59.7 +/- 6.1 and 61.3 +/- 5.5 microg/100 ml, respectively. The corresponding values for zinc were 51.0 +/- 8.9, 53.4 +/- 6.4 and 67.1 +/- 5.5 microg/100 ml, respectively. However, there was no effect of sex on the content of these minerals in the plasma.  相似文献

本文探讨了公驼宝克对氢化可的松注射液所致肾阳虚大鼠的影响.采用氢化可的松注射液肌肉注射14d建立肾阳虚大鼠模型后,以宝克作为受试物进行灌胃干预14d.观察大鼠外观、称量造模前后体重变化和睾丸病理组织学变化.同时检测肾阳虚大鼠血清中睾酮(T)、促甲状腺激素(TSH)、血肌酐(Scr)、尿素氮(BUN)、—氧化氮(NO)、超氧化物歧化酶(SOD)的含量.结果显示宝克对肾阳虚大鼠所表现出的“耗竭”现象逐渐减轻,同时发现宝克具有增加体重,升高T,降低TSH、Scr和BUN含量,提高SOD和NO含量,减轻睾丸病理改变的特性.实验表明宝克能明显改善肾阳虚大鼠的症状.  相似文献   

Regional and circadian variations of sweating rate and body surface temperature in camels (Camelus dromedarius)     

Khalid A. ABDOUN  Emad M. SAMARA  Aly B. OKAB  Ahmed A. AL‐HAIDARY 《Animal Science Journal》2012,83(7):556-561

It was the aim of this study to investigate the regional variations in surface temperature and sweating rate and to visualize body thermal windows responsible for the dissipation of excess body heat in dromedary camels. This study was conducted on five dromedary camels with mean body weight of 450 ± 20.5 kg and 2 years of age. Sweating rate, skin and body surface temperature showed significant (P < 0.001) circadian variation together with the variation in ambient temperature. However, daily mean values of sweating rate, skin and body surface temperature measured on seven regions of the camel body did not significantly differ. The variation in body surface temperature compared to the variation in skin temperature was higher in the hump compared to the axillary and flank regions, indicating the significance of camel's fur in protecting the skin from daily variation in ambient temperature. Infrared thermography revealed that flank and axillary regions had lower thermal gradients at higher ambient temperature (T_a) and higher thermal gradients at lower T_a, which might indicate the working of flank and axillary regions as thermal windows dissipating heat during the night. Sweating rate showed moderate correlation to skin and body surface temperatures, which might indicate their working as potential thermal drivers of sweating in camels.  相似文献

Bactrian camel (Camelus bactrianus) integrins αvβ3 and αvβ6 as FMDV receptors: Molecular cloning, sequence analysis and comparison with other species     

Junzheng Du  Shandian Gao  Huiyun Chang  Guozheng Cong  Tong Lin  Junjun Shao  Zaixin Liu  Xiangtao Liu  Xuepeng Cai   《Veterinary immunology and immunopathology》2009,131(3-4):190-199

Integrins are heterodimeric adhesion receptors that participate in a variety of cell–cell and cell–extracellular matrix protein interactions. Many integrins recognize RGD sequences displayed on extracellular matrix proteins and the exposed loops of viral capsid proteins. Four members of the αv integrin family of cellular receptors, αvβ3, αvβ6, αvβ1 and αvβ8, have been identified as receptors for foot-and-mouth disease virus (FMDV) in vitro, and integrins are believed to be the receptors used to target epithelial cells in the infected animals. To analyse the roles of the αv integrins from a susceptible species as viral receptors, we have cloned Bactrian camel αv, β3 and β6 integrin cDNAs and compared them to those of other species. The coding sequences for Bactrian camel integrin αv, β3 and β6 were found to be 3165, 2289 and 2367 nucleotides in length, encoding 1054, 762 and 788 amino acids, respectively. The Bactrian camel αv, β3 and β6 subunits share many structural features with homologues of other species, including the ligand binding domain and cysteine-rich region. Phylogenetic trees and similarity analyses showed the close relationships of integrin genes from Bactrian camels, pigs and cattle, which are each susceptible to FMDV infection, that were distinct from the orders Rodentia, Primates, Perissodactyla, Carnivora, Galliformes and Xenopus. We postulate that host tropism of FMDV may in part be related to the divergence in integrin subunits among different species.  相似文献
