贾第虫。是在共寄生虫检查中发现的最常见的原生动物;它是胃肠道不适的原因,在儿童和低收入地区的患病率很高。本系统综述更新了有关贾第虫的分子鉴定的现有文献。2017年至2021年在拉丁美洲。
使用了系统审查和荟萃分析(PRISMA)的首选报告项目中建立的指南;该研究涵盖了2017年1月1日至2021年10月3日的时期;搜索集中在贾第鞭毛虫的分子鉴定上。在六个不同的科学数据库中。对发现的材料进行了审查,以仅选择符合纳入和排除标准的论文。
搜索产生了1036种出版物,但只有6个国家的19项调查(巴西,哥伦比亚,古巴,厄瓜多尔,墨西哥,和委内瑞拉)符合选择标准。大多数是在学龄儿童中进行的横断面研究,占主导地位的组合是A和B,而最常见的次级组合是AII,BIII和BIV,最常用的靶基因是tpi和gdh,关于显微镜,分子方法的患病率更高,贾第鞭毛虫病患病率最高的国家是巴西和古巴.
更多的拉丁美洲国家需要生成患病率数据,发病率,和贾第虫病的强度。还需要研究来估计贾第虫病对经济生产力和公共卫生的成本。本系统综述基于现有文献为贾第鞭毛虫的分子鉴定提供了证据。2017年至2021年在拉丁美洲。
Giardia spp. is the most common protozoan found in coproparasitoscopic tests; it is the cause of gastrointestinal discomfort, with a high prevalence in children and in low-income areas. This systematic review updates available literature on molecular identification of
Giardia spp. in Latin America during 2017 to 2021.
The guidelines established in Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used; the study covers the period from January 1, 2017 to October 03, 2021; the search focused on the \"molecular identification of
Giardia spp. in Latin America\" in six different scientific databases. The material found was reviewed to select only those papers that met the inclusion and exclusion criteria.
The search yielded 1036 publications, but only 19 investigations in 6 countries (Brazil, Colombia, Cuba, Ecuador, Mexico, and Venezuela) met the selection criteria. Most were cross-sectional studies carried out in school-age children, the dominant assemblages were A and B while the most frequent subassemblages were AII, BIII and BIV, the most used target genes were tpi and gdh, the prevalence by molecular methods was higher regarding microscopy, the countries with the highest prevalence percentages for Giardiosis were Brazil and Cuba.
More Latin America countries need to generate data of prevalence, incidence, and intensity of Giardiosis. Studies are also needed to estimate the costs of Giardiosis on economic productivity and public health. The present systematic review offers evidence based on the current literature available for the molecular identification of
Giardia spp. in Latin America during 2017 to 2021.
