概括
严重急性呼吸道综合征冠状病毒2 (SARS-CoV-2) 抗体在超过一半的患者中持续至少感染后一年,特别是尖端蛋白抗体,支持潜在的长期免疫力.
科学领域:
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 流行病学 流行病学
背景情况:
- 评估对2019年冠状病毒病 (COVID-19) 幽默免疫反应的持续时间对于有效的疫苗接种策略至关重要.
- 了解感染后抗体持久性,将为公共卫生政策和疫苗开发提供信息.
研究的目的:
- 评估感染后一年内在约旦北部患者中严重急性呼吸系统综合征冠状病毒2 (SARS-CoV-2) 抗体的持久性.
- 评估长期存在的抗体对尖端 (S) 和核囊 (N) 蛋白的存在.
主要方法:
- 进行了一项描述性的横截面研究,其中122名未接种疫苗的参与者感染了早期SARS-CoV-2变种.
- 对S和N蛋白的抗体水平使用定量和定性测试 (罗氏诊断) 来测量.
- 数据使用SPSS进行分析,并对协会进行千-平方测试.
主要成果:

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Sexually Transmitted Infections
1.4K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Pulmonary Tuberculosis II
1.8K
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Immunodeficiency Diseases
2.7K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Pulmonary Tuberculosis I
1.1K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
