Abstract

CEREZO RAMIREZ, Lizbeth Aracely  and  CARBALLO MAMANI, Victor Hugo. Methods for Concentrating and Detecting Parasites in Drinking Water. Gac Med Bol [online]. 2025, vol.48, n.2, pp.132-137.  Epub Dec 31, 2025. ISSN 1012-2966.  https://doi.org/10.47993/gmb.v48i2.1002.

Objective:

The presence of parasites in drinking water poses a critical challenge in disease prevention, underscoring the importance of rigorous water quality monitoring. To ensure the accurate identification of these parasites, standardized concentration methods are essential. Proficiency in applying these concentration and identification techniques is crucial for obtaining precise and reliable results.

Material and Methods:

A reference standard was developed, and various dilutions were prepared to evaluate the efficacy of different parasite concentration methods: spontaneous sedimentation and centrifugation. Statistical tests using SPSS version 22, specifically the Kruskal-Wallis test, were employed to assess the efficiency of the parasite concentration methods and detect significant differences in the number of parasites recovered.

Results:

A significant difference was found between the two methods. The results indicated that centrifugation, in general, allowed for the recovery of a higher number of parasites compared to the sedimentation method.

Conclusions:

This difference highlights the importance of selecting the appropriate method for parasite concentration, as it can directly impact the accuracy of identification and, ultimately, the safety of drinking water. Choosing the most effective concentration method not only improves parasite detection but also significantly contributes to public health protection.
