Objective: To determine the prevalence, richness and parasitic load in wild mammals of Tangamanga I and II Parks in San Luis Potosí, SLP. To assess whether infections are related to the type of feeding and weather seasons.
Design/methodology/approach: Analysis of fresh feces collected for three consecutive days at two sampling stations. Passive flotation techniques with sodium nitrate (qualitative) and McMaster (quantitative) were used.
Results: The overall prevalence observed was 36% (n=242). The parasitic wealth is formed by protozoa: Eimeria sp., Isospora sp. and Cystoisospora sp.; by the cestode Moniezia expansa, nematodes: Toxocara sp., Toxascaris sp., Ancylostoma sp./Uncinaria sp., Strongyloides sp., Trichuris suis and Strongylid eggs. The parasite load in the case of protozoa was in the range of 0 – 8505 oocysts per gram of faeces, and 0 – 1400 eggs per gram of faeces in the case of helminths. Statistical analyses showed that the prevalence of parasites does not depend on the climatic season, and only in Tangamanga II Park is the prevalence dependent on the type of feeding (herbivores).
Study limitations/implications: The conservation method used limits the stool test techniques that can be employed (stool culture or sporulation).
Findings/conclusions: Endoparasitic infections can be a potential risk to the health of animals. In particular to those of great genetic value such as species threatened with extinction. In addition, the potentially zoonotic parasites observed pose a threat to the health of caregivers
