A study of 251 stool samples collected from patients in Angola has noted a high prevalence of multiple parasites. In this study, researchers used genetic tools to genotype each of the parasites detected, creating one of the few studies to provide genotyping of multiple parasitic infections in a single paper. The researchers report that, “Prevalences of S. stercoralis, G. duodenalis, Cryptosporidium spp., and Blastocystis spp. were estimated at 21.4% (95% CI: 17.1-25.7%), 37.9% (95% CI: 32.8-43.0%), 2.9% (95% CI: 1.1-4.5%) and 25.6% (95% CI: 21.18-30.2%), respectively.” The study was published in BMC Parasites and Vectors.
