Abstract

Cryptosporidium spp. and Giardia duodenalis are an important food borne parasites which cause gastrointestinal disease in animals and humans. Globally, they are ranked high among the most important foodborne pathogens by FAO and WHO. The overall objective of the present study is to use a multi-disciplinary, One Health approach to tackle issues associated with foodborne parasites, addressing existing gaps in our knowledge regarding occurrence, transmission, epidemiology, harmonization of methods, and prevention. Within present study we aimed to characterise the epidemiology of Cryptosporidium spp. and G. duodenalis and potential transmission routes by summarizing the available data about human cases of cryptosporidiosis and giardiasis in Latvia data from studies regarding Cryptosporidium spp. and G. duodenalis prevalence and molecular diversity in food producing and companion animals. Cryptosporidiosis cases in humans have only been reported since 2009, with a total of 71 cases being reported from then until 2020 (mean: 6 cases per year, range: 2–23 cases per year). Meanwhile, from 2000 to 2020, a total of 1,000 cases of giardiasis were reported (mean: 48 cases per year, range: 3–172 cases per year). Cryptosporidium spp. were shed by 33.8% of the investigated cattle and 15.2% of companion dogs, while G. duodenalis were shed by 5.9% of the investigated cattle and 11.9% of companion dogs. Findings of C. parvum species and most common subtype IIaA15G2R1 and presence of G. duodenalis assemblage A in animals highlights the zoonotic potential of those pathogens in Latvia. The zoonotic aspects of Cryptosporidium spp. and G. duodenalis needs to be taken into account, and need to be addressed in future studies. This study was funded by the European Regional Development Fund “1.1.1.2. “Post-doctoral research aid” “One Health” multidisciplinary approaches for epidemiology and prevention of selected parasitic zoonosis (OMEPPAZ), (1.1.1.2/VIAA/1/16/204)”.
