概括

在患有淋巴腺炎的狗中发现了Mycobacterium avium complex (MAC) 和Mycobacterium tuberculosis (MTB),这突出了潜在的动物感染威胁. 这项研究强调了诊断这些被低估的犬类淋巴腺炎细菌病因的重要性.

科学领域:

兽医医学兽医医学兽医医学
微生物学微生物学
动物传播疾病动物传播疾病

背景情况:

菌复合体 (MAC) 是人类免疫抑制性疾病的重要原因,也是新兴的动物传染病威胁.
马克越来越多地对人类的非结核菌菌 (NTM) 感染和动物的病原性感染负责.
虽然狗通常具有耐药性,但MAC感染可能导致全身性疾病,并对所有者构成动物感染风险,特别是通过便传播.

研究的目的:

调查患有淋巴腺病的狗中MAC和其他Mycobacteria的患病率.
为了强调这些细菌在犬类淋巴腺炎中的作用.

主要方法:

分析了123个样本 (淋巴结吸附物,组织,血液) 来自83只疑似淋巴腺炎和其他慢性疾病的狗.
使用Ziehl-Neelsen染色的细胞学和显微镜检查.
在Middlebrook 7H11介质上培养细菌,并通过三重嵌聚合酶链反应 (nPCR) 进行分子检测.

主要成果:

细胞学检查显示了淋巴结组织中的炎症性炎症和酸性快速生物.
在83只狗中,在8只狗中检测到Mycobacterium物种.
其中三例确诊为MAC,五例属于Mycobacterium结核综合体 (MTB综合体).

结论:

马克和MTB复合体是低估的细菌病原体,有助于动物的淋巴腺炎.
这些发现凸显了Mycobacterial感染对伴侣动物的潜在动物传染性影响.

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
