Latitudinal variability in the seroprevalence of antibodies against toxoplasma gondii in non-migrant and arctic migratory geese
Toxoplasma gondii is an intracellular coccidian parasite found worldwide and is known to infect virtually all warm-blooded animals. It requires a cat (family Felidae) to complete its full life cycle. Despite the absence of wild felids on the Arctic archipelago of Svalbard, T. gondii has been found i...
