Incidence of Salmonellae in Captive and Wild Free‐Living Raptorial Birds in Central Spain     

M. P. Reche  P. A. Jimnez  F. Alvarez  J. E. García de los Ríos  A. M. Rojas  P. De Pedro 《Zoonoses and public health》2003,50(1):42-44

A total of 595 faecal samples from raptorial birds, either captive or free‐living, residing in GREFA Wildlife Hospital were bacteriologically examined using various selective media and an Automated Diagnostic Assay System for Salmonella detection. Serotype and phage type of the strains identified as Salmonella was determined. In the captive group, of the 285 samples examined, 21 (7.36%) were positive for Salmonella. Serotyping revealed that most of the individuals were infected by Salmonella serotype Havana. This result suggested that there could be a source of contamination in the Hospital although it could not be established. In the wild free‐living group, over 310 samples examined (4.19%) were positive for Salmonella. The Salmonella isolates showed a major variety of serotypes: Enteritidis, Adelaide, Brandenburg, Newport, Typhimurium, Hadar, Saintpaul and Virchow. Most of them are similar to those commonly described in isolates from human and domestic animals. These results indicate that wild birds could be involved in the dissemination of Salmonella in humans or domestic animals or vice versa.  相似文献

鸡球虫病的免疫控制   总被引：9，自引：0，他引：9  

Shirley M.W  蔡建平  谢明权 《中国家禽》2003,25(7):33-35

球虫一旦感染鸡并在其体内定居,就处于宿主免疫系统的监测下并设法建立寄生生活。球虫在鸡体内最长可持续生存14天,且几乎都位于宿主肠壁深层的细胞内,并完全依赖于宿主营养,最多可进行4代生长、增殖(无性生殖)的过程。鸡在感染后数小时即对球虫产生反应,大约4天即可产生特异性的保护性免疫反应,且足以限制再感染。免疫反应强度与许多因素有关,如感染剂量及感染虫种的特性等,但通常一次摄入少量卵囊即足以诱导能充分抵御再感染的免疫反应。虽然认为免疫接种是控制鸡球虫病的实用方法已有50多年,但在化学治疗的鼎盛时代,疫苗使用常被忽略,仅…  相似文献

藏系绵羊随机扩增多态性DNA最佳反应体系的研究   总被引：2，自引：1，他引：1  

杨晓军  赵有璋 《中国草食动物》2003,23(2):3-6

以高原型藏羊的基因组DNA为模板，通过对RAPD反应体系中的各种参数进行优化试验，建立了适宜于藏系绵羊RAPD分析的最佳反应体系：在PE2400型DNA扩增仪的25μL反应体系中，模板DNA的量为60－120ng，引物量为4－8pmol，Mg^2 浓度为2.0mM，Taq DNA聚合酶为1－2.5U,dNTP浓度为150－200μM;94℃预变性3分钟后35次循环的参数设定为：94℃1分钟，36℃1分钟，72℃2.5分钟，最后72℃延伸10分钟，利用这些条件对藏系绵羊的基因组DNA进行RAPD分析，其结果的重复性和可靠性大为提高。  相似文献   

Analysis of In vitro Fertilizing Capacity to Evaluate the Freezing Procedures of Boar Semen and to Predict the Subsequent Fertility     

E Sellés  J Gadea  R Romar  C Matás  S Ruiz 《Reproduction in domestic animals》2003,38(1):66-72

A porcine in vitro fertilization (IVF) system and seminal quality parameters of frozen–thawed boar semen were used to assess the effectiveness of two different thawing rates of frozen boar semen, and to address the question of whether differences between fertility of ejaculates could be predicted in a limited field trial. In the first experiment, two thawing procedures were analysed (37°C, 30 s; 50°C, 12 s) and no differences in sperm quality were found. However, when the procedure was 50°C, 12 s the IVF results showed a higher number of sperm per penetrated oocyte and a near 10 points higher rate of pronuclear formation. In the second experiment, the fertility results obtained in the limited field trial show to be efficient enough for application in a commercial use, especially for three of the employed boars (fertility ≥80%). In this limited study, the conventional seminal parameters are not accurate enough to discriminate good and bad boars in relation to fertility. On the contrary, parameters of in vitro penetrability are more precise to predict subsequent fertilities. As conclusion, the IVF fertilization system seems to be a good tool to evaluate the quality of frozen–thawed boar semen previous to its commercial way, to verify the bank semen storage quality and a good way to assay new sperm freezing procedures, as it is the more precise evaluating method in estimating the potential fertilizing ability.  相似文献
