Abstract

Over a one-year period, 1390 faecal samples were submitted to Aberystwyth Public Health Laboratory for routine microbiological examination. All were stained using a commercial trichrome method. Blastocystis hominis was detected in 96 (6.9%), making it the most common parasite found in the study. Of the B. hominis-positive specimens, 73% were missed on direct microscopy. Molecular typing of B. hominis has revealed extensive genetic diversity in morphologically identical strains and thus detection by microscopy alone may not be sufficient to confirm the role of this organism in human disease.

摘要

在一年的时间里，1390份粪便样本被送到阿伯里斯特威斯公共卫生实验室进行常规微生物学检查。所有样本均采用商用三色染色法进行染色。在96份（6.9%）样本中检测到了人芽囊原虫，这使其成为该研究中发现的最常见寄生虫。在人芽囊原虫阳性样本中，73%在直接显微镜检查中被漏检。人芽囊原虫的分子分型显示，形态相同的菌株存在广泛的遗传多样性，因此仅靠显微镜检查可能不足以确认该生物体在人类疾病中的作用。
