“…Domestic animals, including pets, are responsible for spreading pathogens to humans and sympatric wildlife [1][2][3]. Notable examples include dogs transmitting rabies to humans [4] or cattle transmitting Cryptosporidium parvum to humans and sympatric wild ruminants [5,6].…”

Who let the cats out? A global meta-analysis on risk of parasitic infection in indoor versus outdoor domestic cats (Felis catus)

Parasitic infection risks in domestic animals may increase as a result of outdoor activities, often leading to transmission events to and from owners, other domestic animals and wildlife. Furthermore, outdoor access has not been quantified in domestic animals as a risk factor with respect to latitude or parasite transmission pathway. Cats are an ideal model to test parasitic infection risk in outdoor animals because there have been many studies analysing this risk factor in this species; and there is a useful dichotomy in cat ownership between indoor-only cats and those with outdoor access. Thus, we used meta-analysis to determine whether outdoor access is a significant risk factor for parasitic infection in domestic pet cats across 19 different pathogens including many relevant to human, domestic animal and wildlife health, such as Toxoplasma gondii and Toxocara cati . Cats with outdoor access were 2.77 times more likely to be infected with parasites than indoor-only cats. Furthermore, absolute latitude trended towards significance such that each degree increase in absolute latitude increased infection likelihood by 4%. Thus, restricting outdoor access can reduce the risk of parasitic infection in cats and reduce the risk of zoonotic parasite transmission, spillover to sympatric wildlife and negative impacts on feline health.

“…Helminthology research on rodents began more than a century ago (POUPIN, 1897); however, articles on this topic are scarce, most of which have adopted a taxonomic approach (ÁLVAREZ, 1960;DENKE & MURÚA, 1977;ALCAÍNO & GORMAN, 1990) and only occasionally provided a description of the ecological background (CATTAN et al, 1992;LANDAETA-AQUEVEQUE et al, 2018). Given that the Chilean territory is a biogeographic island, the assembly of rodents (and their parasites) has resulted from historical interactions and ecological factors on several temporal scales (CATTAN et al, 1992;LANDAETA-AQUEVEQUE et al, 2014a, 2018.…”

Helminth parasites are still not a well-known component of animal biodiversity. In this study, we describe and compare the endoparasite assemblages of three native rodent species from a semiarid Mediterranean ecosystem. A total of eight species of gastrointestinal helminth parasites were detected. The endoparasitic communities of the rodents Phyllotis darwini (5 species), Octodon degus (4 species), and Abrothrix olivaceus (3 species) were described in terms of their prevalence and mean abundance. In addition, endoparasite records by rodent species were submitted to rarefaction analyses to verify sampling robustness and used to compare richness and similarity among rodent species. O. degus presented the highest prevalence and parasitic load, but was of low diversity, while P. darwini presented the highest diversity, but had a low prevalence rate. Conversely, A. olivaceus presented the lowest prevalence and diversity. This study contributes to the existing knowledge of the endoparasitic fauna of rodent species from semiarid Mediterranean zones.

“…However, few surveys have studied factors that favour host switching of parasites between native and introduced hosts (e.g. Landaeta-Aqueveque et al 2014). Regarding phylogenetic factors, although generalist native parasites have been found in introduced rodent species belonging to different families (Pisanu et al 2009), some studies show that there is a decrease in the probability of transmission as an effect of increase in the taxonomic distance between hosts (Wells et al 2015; Young et al 2017).…”

“…In continental Chile, a region of a substantially isolated nature (see Landaeta-Aqueveque et al 2014), there is evidence of parasite transmission between native and introduced rodents (Landaeta-Aqueveque et al 2007 a , b ). Rodents in Central Chile belong to two suborders, Myomorpha, including the families Muridae (introduced species) and Cricetidae (native species), and Hystricomorpha (native species, hereafter non-cricetid) including the families Octodontidae and Abrocomidae (Muñoz-Pedreros, 2009).…”

Phylogenetic and ecological factors affecting the sharing of helminths between native and introduced rodents in Central Chile

In order to analyse the effect of hosts' relationships and the helminthic load on the switching of parasites between native and introduced hosts, we sampled rodents belonging to two suborders from Central Chile. We compared the number of helminthic species shared between murids (introduced) and cricetid (native, same suborder) rodents to those shared between murids and hystricomorphs (native, different suborder), and we assessed the association between parasitic presence, abundance and geographical dispersion in source hosts to the presence and abundance in recipient hosts. Introduced rodent species shared more helminth species with cricetid rodents than with non-cricetids. Presence and abundance in recipient hosts was not associated with the prevalence and mean abundance in source hosts' population. The mean abundance of parasites in source hosts throughout the territory and wider dispersion was positively associated with the likelihood of being shared with a recipient host. Closer relationships between native and introduced hosts and high parasitic abundance and dispersion could facilitate host switching of helminths between native and introduced rodents. This work provides the first documentation of the importance of parasitic abundance and dispersion on the switching of parasites between native and introduced hosts.
