Irisin, a novel peptide, was initially been shown to be expressed explicitly in the muscle tissues. We studied the presence of irisin immunoreactivity in porcupine adrenal glands and kidneys. Immunocytochemistry showed that irisin was localised both in the adrenal cortex and adrenal medulla. In organs, irisin immunoreactivity was found in the tubular and collecting system of the nephron. The functional role of irisin in the adrenal gland and kidney has not been precisely yet. However, irisin might have a paracrine and autocrine function as do other locally produced peptides. 相似文献

不同公母配比对提高豪猪繁殖性能的影响 总被引:1,自引:1,他引:0
为探讨不同公母配比对提高豪猪产仔数、存活数等繁殖性能的影响。选取2岁左右、胎次及产仔数相近的成年豪猪92只(32公60母),随机分为5组,每组4个重复,分别按1公1母、1公2母、1公3母、2公5母、3公4母搭配分成5种试验方案,各组采用相同的日粮进行饲喂,经过1年的试验,期间记录各组豪猪的流产母豪猪数、产仔母豪猪数、产仔数、食仔数、成活仔豪猪数。结果表明:5种不同的公母搭配中,公母配比为1公2母的产仔率和仔豪猪的成活率分别达到了87.50%、94.12%,平均产仔数为2.13只,繁殖性能和经济效益最理想。 相似文献

【目的】 查明引起福建省龙岩市某豪猪养殖场致豪猪腹泻死亡的病原菌及其特征,为该病的科学防控及合理用药提供参考依据。【方法】 分离腹泻死亡豪猪的病原,并结合形态特征、生理生化试验、16S rRNA基因扩增、种系发育分群鉴定分离菌株;通过毒力基因检测、动物致病性试验及药敏试验对分离菌株的致病性和耐药性进行研究。【结果】 从发病死亡豪猪肝脏组织中分离到1株大肠杆菌,命名为Fj/Porcupine2018,该分离菌株与22株不同来源的参考菌株16S rRNA序列之间的相似度为97.4%~99.8%,其中与禽源分离株(登录号:MN022583)和人源分离株(登录号:MW881377)的序列相似度高达99.8%;种系发育分群证实该分离菌株属于B1群。毒力基因检测结果显示,该分离菌株除检出肠侵袭型大肠杆菌毒力基因EinV外,还检出papC、iroC、Afa、luxs、stx2f及ompA 6种毒力相关基因。动物致病性试验显示,该分离菌株对小鼠具有较强的致病性,小鼠在攻毒后31 h内全部死亡,且肝脏、脾脏、肺脏及肠道等器官组织均有明显的病理损伤;在对常见抗菌药物的药敏试验中,该分离菌株对大环内酯类、四环素类、喹诺酮类、磺胺类、头孢类、氨基糖苷类、青霉素类7类11种药物表现出不同程度的耐药,耐药率为25%~100%,仅对头孢曲松和头孢西叮2种药物表现敏感。【结论】 本研究分离获得了1株腹泻死亡豪猪的病原菌大肠杆菌,通过一系列生物学特性研究证实该分离菌为1株具有较强致病力且呈现多重耐药性的B1群肠侵袭型大肠杆菌,为豪猪等野生动物大肠杆菌病的防控提供了重要的参考依据。 相似文献

This research study evaluated the effect of different additives on the bait consumption by Indian crested porcupine, a serious forest and agricultural pest, under field conditions. Different additives (saccharin, common salt, bone meal, fish meal, peanut butter, egg yolk, egg shell powder, yeast powder, mineral oil and coconut oil) at 2 and 5% each were tested for their relative preference, using groundnut–maize (1:1) as basic bait. All the additives were tested under a no‐choice test pattern. For control tests, no additive was mixed with the basic bait. Saccharin at 5% concentration significantly enhanced the consumption of bait over the basic bait, while 2% saccharin supplemented bait resulted in a non‐significant bait consumption. All other additives did not enhance the consumption of the bait material; rather, these worked as repellents. However, the repellency was lowest with the common salt, followed by egg yolk, egg shell powder, bone meal, peanut butter, mineral oil, fish meal and yeast powder, while coconut remained the most repellent compound. The present study suggested that groundnut–maize (1:1) supplemented with 5% saccharin was the preferred bait combination, and can be used with different rodenticides for the management of Indian crested porcupine. 相似文献

Uncoupling protein 1 (UCP-1) was believed to be an exclusive protein found in the brown adipose tissue of small rodents and humans; however, recent studies show that the expression of UCP-1 protein has been found in the sebaceous glands of the mouse tail and human skin. There are a few reports about the presence of UCP-1 in the sebaceous glands of other rodents, such as the Sunda porcupine (Hystrix javanica), a wild spiny rodent commonly found in Indonesia with a large sebaceous gland. The aim of this study was to identify the presence of UCP-1 in the sebaceous glands on the skin of the Sunda porcupine. The skin from three regions (thoracodorsal, lumbosacral and apex caudal) of eight adult Sunda porcupines was used to detect UCP-1-immunopositive cells through immunohistochemistry. All three regions were found immunopositive to anti-UCP-1 antibody in the sebaceous gland of quill and hair follicles, and the epidermal layer in quill and hair follicles with various intensities. The result of immunohistochemistry revealed that the thoracodorsal and apex caudal region was the most intense immunoreaction followed by the lumbosacral region. These findings proved that the presence of UCP-1 was also identified in the sebaceous glands of other rodent (Hystrix javanica) and regions of the body, which has not been reported previously. 相似文献
