概括
在苏丹,杆菌仍然是一个主要问题,在卡萨拉州,杆菌的患病率很高. 目前基于学校的大规模药物管理 (MDA) 不足,需要更广泛的控制策略.
科学领域:
- 公共卫生 公共卫生
- 传染性疾病 传染性疾病
- 热带医学 热带医学
背景情况:
- 尽管全球采取了控制措施,但苏丹仍然面临istosomiasis作为一个重大的公共卫生挑战.
- 全国范围的调查显示,持续存在的"热点"地区需要有针对性的干预.
- 基于学校的大规模药物管理 (MDA) 是卫生当局实施的主要控制策略.
研究的目的:
- 评估苏丹卡萨拉州高endemic社区中Schistosoma mansoni和Schistosoma haematobium感染的流行率和强度.
- 为了确定与杆菌病相关的人口和环境风险因素.
- 评估目前在持久传播区域的控制策略的有效性.
主要方法:
- 在新哈尔法和纳尔阿特巴拉地区的40个村庄进行了基于社区的横截面调查.
- 从3,889名居民收集了便和尿液样本,以诊断S. mansoni (Kato-Katz) 和S. haematobium (尿液离心).
- 使用双重障碍模型建模了患病率和强度;通过家庭访谈收集了社会人口统计和行为数据.
主要成果:
- 曼索尼菌的流行率在新哈尔法是28.0%,在纳尔阿特巴拉是24.3%,其中一个村庄的流行率达到68.2%.
- 在40个被调查的村庄中,有25个村庄超过了S. mansoni的20%流行率值,这表明广泛的高特有性.
- S. haematobium 的流行率很低 (2.1%在新哈尔法,没有在纳尔阿特巴拉),但在两个村庄超过10%.
- 在20岁及以上的个体中观察到高感染率,这表明传染超出了学龄儿童.
结论:
- 目前针对学龄儿童的仅使用MDA的方法不足以控制持续性杆菌病的传播.
- 有效的控制需要更新国家指导方针,扩大微型规划的MDA,社区范围内的宣传活动,以及改善水和卫生基础设施.
- 民间冲突和药物获取的减少加剧了杆菌病的情况,突显了迫切需要国际支持的需要.

Fungal Phylum Microsporidia
395
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Factors Affecting the Risk of Infection
13.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
