David Modrý Foto

David Modrý is the Head of Department of Pathology and Parasitology at UVPS and managing director of Veterinaires sans Frontieres Czechia. David is the holder of and participates in various training projects in developing countries. He has taken part in more than 20 field research and education missions to Near East and 20 to Central and East Africa. David devotes his research to parasites and parasitic diseases of primates (diagnostics, taxonomy, biology, ecology, EIDs, zoonotic infections), conservation medicine, ecology and evolution of protozoan parasites.


The Key Participants of the Lab Team

Cécile Néel is primatologist with a long-term experience with field work in Africa. Cécile has studied the socio-ecology of western lowland gorillas and central chimpanzees and worked on developing the non-invasive methods that would help studying the origin of HIV and malaria in these species. Cécile´s general research interests focus on zoonosis, pathogen transmission in relation to the social structure of the hosts, phylogeography, and modelling of disease spread using GIS and remote sensing technologies.

Rui Miguel Moutinho Sá Foto

Rui Sá is biological anthropologist working on chimpanzee genetics and parasitology in Africa (Guinea-Bissau). Rui has extensive experience in ethnoecology, non-invasive sampling techniques, diverse molecular and parasitological methods, genomic analyses, and ethnographic methodologies. Currently, Rui is focused on neglected and emergent gastrointestinal parasites of humans and other primates.


Senior Researchers

Klára J. Petrželková has been involved in great ape research in Africa since 2003. In collaboration with Primate Research Institute, Kyoto University, Japan, Klára carried out research focused on parasite fauna of chimpanzees: a project on introduced population at Rubondo Island National Park, Tanzania and a project in Kalinzu Forest Reserve, Uganda. In 2007, Klára initiated a long term on-going collaborative project in Dzanga Sangha Protected Areas which deals with diversity and ecology of parasites and bacteria of western lowland gorillas with respect to the impact of human pressure. Currently, Klára collaborates with Ugalla Primate Project to study parasites and viruses of savanna chimpanzees in Tanzania.

Martin Kváč Foto

Martin Kváč is the Head of Laboratory of Veterinary and Medical Protistology, Biology Centre, Academy of Sciences of the Czech Republic. Martin devotes his research to opportunistic protists, especially Cryptosporidium, microsporidia and Giardia in human, farm, captive and wild animals, including diagnostics, infectivity, pathogenicity, taxonomy, immunology and relation to hosts. Currently, Martin works mainly on co-evolution of Cryptosporidium species and genotypes with their host, transmissions of Cryptosporidium, microsporidia and Giardia of between both domestic and wild animals and great apes in Africa, and course of microsporidiosis in relation to host’s immunodeficiency in human.


Jan Votýpka is associated professor in the Department of parasitology (Charles University in Prague) and in the Institute of parasitology (Academy of Science in České Budějovice). Jan participates in various field researches and in training projects in Mediterranean basin (e.g. Israel, Turkey, Tunisia etc.) and in developing countries (e.g. Central African Republic, Kenya, Ghana etc.) and his teaching activity includes more than ten courses. Currently, Jan works mainly on parasite biodiversity, parasite-host interactions and transmissions of various pathogens by haematophagous insect.

Junior Researchers

Kateřina Pomajbíková Foto

Kateřina Pomajbíková participates on the several projects focused on the symbionts and parasitofauna of free-ranging great apes and humans. Kateřina´s research is focused mainly on diversity and cross-species transmissions of amoebas of the genus Entamoeba in wild African great apes, on the mutualistic and pathogenic ciliates (e.g. Troglodytella abrassarti or Balantidium coli), diversity of malaria protist of the genus Plasmodium in primates and parasitofauna of wild agile mangabeys in Central African Republic.


Bohumil Sak is a research scientist in Laboratory of Veterinary and Medical Protistology, Biology Centre, Academy of Sciences of the Czech Republic. His research is aimed to opportunistic protists, especially microsporidia in human, farm, captive and wild animals, and includes diagnostics, taxonomy and experimental infection studies. Currently, Bohumil works mainly on epidemiology and epizootology of microsporidia species, their possible transmissions between both human and wild animals including great apes in Africa and vice versa, and course of latent microsporidiosis in immunocompetent hosts in general.

Ilona Psenkova

Ilona Pšenková conducted her PhD study on entodiniomorphid ciliates of gastrointestinal tract of great apes, their diversity and hydrolytic activities and described their contribution to ape digestion. Currently Ilona is focused on monitoring of gastrointestinal parasites of Ugalla chimpanzees (in connection to SIV) and gorillas from Central African Republic (Dzanga-Ndoki National Park). Ilona also works on cross-transmission of strongylid nematodes between great apes and humans at several research sites in Africa.


Peter Vallo has been focusing since his PhD studies at molecular phylogenetics and taxonomy of Afrotropical bats at the Institute of Vertebrate Biology, Academy of Sciences of the Czech Republic, in Brno. In the past, Peter collaborated also with our veterinary parasitology team in a study on genetic variability of a ciliate Troglodytella abrassarti from chimpanzees. Currently, Peter is working on assessment of molecular genetic variation in strongylid nematodes of the genera Mammonogamus and Necator in African primates, and reconstruction of their phylogenetic relationships and possible transmission to other, human and non-primate hosts.

Dagmar Jirsová

Dagmar Jirsová finished her BSc. and MSc. at the Fakulty of Science, University of South Bohemia in České Budějovice specialized at phylogenetic relationships of trematodes of the families Opisthorchiidae and Heterophyidae. Currently, Dagmar works on population and evolution genetics of Wenyonia virilis from Nile basin, evolution and colonization of Hepatozoon sp. at Canary Islands, intraspecific competition of co-infections between T. brucei and T. evansi.
