 Cryptosporidium and Giardia are common causes of diarrheal illness worldwide, and can cause significant morbidity and mortality in some populations. These protozoan pathogens are often detected using antigen-based assays, which have been shown to miss up to 40% of cases when compared to molecular methods. In this study, researchers investigated the use of molecular methods to detect Cryptosporidium and Giardia infection in campylobacter positive individuals. They found that the use of molecular methods increased the detection rate of both protozoans with one method detecting 9% more cases than the other. Additionally, they found that the use of bee-beating prior to DNA extraction did not significantly improve the sensitivity of the molecular methods. This suggests that molecular methods should be used as the primary diagnostic tool for Cryptosporidium and Giardia infection in campylobacter positive individuals.
