SB-C holds a contract by CAM and NextGenerationEU Funds (27-UAH-INV).The observation reported here is noteworthy because it represents a rare case of double heterogeneric (co)infection in a single host erythrocyte. The low frequency of these observations in the sample suggests that the co-occurrence of one Schellackia sporozoite and one Karyolysus gametocyte within a single host erythrocyte would not benefit either the parasites or the host. We conclude that it represents a stochastic event of single host cell coinfection.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://www.biotaxa.org/hn/article/view/81141open access576.89598.112CoinfectionKaryolysusSchellackiaPsammodromus algirusParasitesParasitología (Veterinaria)Reptiles2401.12 Parasitología Animal2401.16 Herpetología
