背景情况:

狗病,由*Leishmania infantum*引起,是狗的重大病媒传播疾病,在地中海地区尤为普遍.
这种疾病会导致严重的健康恶化,如果不治疗,可能致命.
越来越多的野生动物报告Leishmaniasis,这表明潜在的传播超出了家禽种群.

研究的目的:

为了调查西北西班牙狼群中Leishmania infantum的存在,特别是西拉库莱布拉山脉附近的狼群.
为了记录该地区狼群中首次确诊的莱什曼病例.

主要方法:

使用聚合酶链反应 (PCR) 检测L. infantum的DNA.
分析了非侵入性样本,包括口腔粘膜,耳朵拭子和头发.
包括来自活狼 (21) 和尸体 (18) 的样本.

主要成果:

在39只被采样的狼中,在18只狼中检测到L. infantum* DNA,导致阳性率为46.1%.
证实了塞拉德拉库莱布拉地区狼群中寄生虫的存在.
检测在不同样本类型和动物来源 (活体与尸体) 中是一致的.

结论:

这项研究提供了西北西班牙狼群中莱什曼病的第一个证据.
这些发现凸显了狼在野生动物中作为Leishmania infantum*的宿主或储库的潜在作用.
需要进一步的研究来了解狼群中莱什曼病的流行病学影响及其对疾病传播动态的潜在影响.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Bacterial Phylum Spirochaetes

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...
