“…Regarding the parasitological evaluation of the crab-eating fox, non-embryonated ascarid-type eggs (51.21 × 51.57 μm) with a thick eggshell and a coarsely pitted surface containing multiple excavations were observed (Figure 3A). The morphological traits of the egg correspond well to Lagochilascaris minor, previously described in South American wild carnivore definitive hosts (37,38). Additionally, parasite stages (i.e., adults and eggs) of the diphyllobothriidean species Spirometra mansoni were detected.…”

Neglected zoonotic helminthiases in wild canids: new insights from South America

et al. 2023

The global threat of neglected tropical diseases (NTDs) constitutes a public health issue in underdeveloped countries. Zoonotic helminthiases are the most common human NTD agents in developing countries in sub-Saharan Africa, Asia, and the Americas, causing a global burden of disease that exceeds that of more recognized infectious diseases such as malaria and tuberculosis. Wild canids are well-known mammals that act as natural reservoirs of zoonotic-relevant helminthiasis worldwide, thus playing a pivotal role in their epidemiology and transmission to humans. Here we evaluate the occurrence of zoonotic gastrointestinal helminths in two Neotropical wild canid species from the Amazonian and Andean regions of Colombia, i.e., the bush dog (Speothos venaticus) and the crab-eating fox (Cerdocyon thous). We recovered tapeworm proglottids from bush dog fecal samples and identified them molecularly as the canine-specific lineage of Dipylidium caninum by using cytochrome c oxidase subunit I (cox1) gene sequences. Moreover, examination of a crab-eating fox during necropsy revealed the presence of non-embryonated eggs of the neglected nematode Lagochilascaris cf. minor, in addition to eggs and gravid proglottids of the cestode Spirometra mansoni. These findings represent the first report of zoonotic-relevant cestodes, i.e., D. caninum (“canine genotype”), S. mansoni, and the nematode L. cf. minor, in bush dogs and crab-eating foxes as final hosts. The occurrence of these zoonotic helminthiases in wild canid species calls for regular monitoring programs to better understand the epidemiology and transmission routes of neglected dipylidiasis, lagochilascariosis, and sparganosis in South America.

Abstract The aim of the present study was to evaluate the state of knowledge about the helminthology of wild mammals in Argentine Patagonia and its link with the conservation of parasite species and biodiversity. To this end, the information included in the previously reported checklist of the helminths found in terrestrial wild mammals of Argentine Patagonia was completed and updated. The methodology used for the search was the same as that previously used, with slight modifications. Eighty-two species of mammals currently inhabit the region, and an additional six species are considered to have become extinct before the 20th century. The reports used to complete and update the information correspond to research done since 2015 to date. Considering the number of records analysed in the previously reported checklist and those of the current update, a total of 1918 helminthological reports for current Patagonian mammals and 2141 on mammal species that inhabited Patagonia before the 20th century were accounted for. It is important to point out that 41% of the 82 species of wild mammals currently inhabiting Patagonia have not been studied helminthologically; 38% of these without helminthological records are either threatened or do not have categorization, and 79% of mammals without helminthological studies have some degree of endemism. Therefore, in order to evaluate conservation priorities, the information about the parasitic richness in Patagonian wild mammals should be substantially increased, especially in those endangered or endemic.

“…Human Lagochilascariasis can also be found in cats and dogs. This disease is considered an emerging zoonosis in America distributed from Mexico to Argentina and the Caribbean islands (Barrera-Pérez et al 2012;Christello Trindade et al 2019). It is a silent and chronic disease, and over the course of years the symptoms may be hidden.…”

Zoonoses Associated with Geohelminthiases

This chapter presents a general and updated overview of the different zoonoses associated with soiltransmitted helminth infections. The topics presented in the chapter are: Angiostrongyliasis; Ascariasis; Capillariasis; Lagochilascariasis; Mammomonogamiasis; Strongyloidiasis; Cutaneous larva migrans. In this context, zoonotic diseases are a major public health problem because animals are the source of human pathogens. The emergence and re-emergence of zoonotic diseases have been attributed to a number of anthropogenic and natural factors, including vector biology, urbanization, climate change, animal migration and trade, travel and tourism, among others. Animals are the origin of a large number of infectious diseases that affect humans. About 60% of newly discovered human infections are zoonotic. Because of this, it is important to consider the areas where we live and the risks of latent diseases in the regions. In addition, it is extremely important to give importance to common wound accidents, because it is better to prevent silent diseases that can be hidden for years through good food and wound asepsis and go to the doctor.
