“…Domestic cats are obligate carnivores and annually consume billions of birds and small mammals as prey [ 22 ]. In addition, rodents that coexist with wild felines were found to have high T. gondii infection rates [ 32 ]. Feral cats do not have specific owners and are thus not subjected to prophylactic programs and do not receive treatment against parasites.…”

The present study investigated the prevalence of Toxoplasma gondii and other intestinal parasites in cats in the Tokachi subprefecture in Japan. A total of 365 household cats were included in the study, and 353 serum and 351 fecal samples were collected and analyzed. T. gondii IgG antibodies were detected in the sera of 16.14% of cats based on Latex agglutination test and ELISA. For ELISA, T. gondii RH strain tachyzoites lysate and T. gondii SAG2 recombinant protein were used as antigens. Low seropositivity was detected in cats younger than one year and older than 11 years; outdoor and hunter cats showed significantly high seropositivities. Neutering either in male or female cats, but not gender, had a considerable effect on seroprevalence. Toxoplasma gondii oocysts were detected in one fecal sample. The overall parasitic infestation in cats was 12.5%. Other detected parasites included Toxocara species, which showed the highest prevalence of 7.7%, followed by Isospora spp. (2%), Taenia spp. (1.7%), and Ancylostoma spp. (0.9%). Spirometra spp. was detected in only one sample. Outdoor cats comprised 50% of all 44 parasite-infested cats. Although T. gondii oocysts were detected in only one sample, the relatively high seroprevalence of T. gondii indicated that it can pose significant risks to the environment. Our findings highlighted the potential of outdoor cats as a source of T. gondii and other parasites.

To assess the prevalence of Toxoplasma gondii infection in native and commensal rodents as indicators of environmental pollution, we analyzed brain tissue from small mammals collected on legal and illegal waste sites in the Slovenian and Croatian parts of Istria. A total of 136 animals and five species of the family Muridae were analyzed: black rat (Rattus rattus), domestic mouse (Mus musculus), wood mouse (Apodemus sylvaticus), striped field mouse (Apodemus agrarius), and yellow-necked mouse (Apodemus flavicollis). Using quantitative Polymerase Chain Reaction (qPCR), T. gondii DNA was detected in four homogenized brain tissue samples (2.94%), from all of the analyzed species, except black rat. Out of these, two samples, domestic mouse (Mus musculus) and wood mouse (Apodemus sylvaticus) had sufficient DNA for genotyping of T. gondii isolates in which we demonstrated the presence of clonal type II using RFLP PCR with four markers (SAG1, SAG2, GRA6 and GRA7). Three of four infected animals (75%) were collected on dumpsites.

“…Antibodies to T. gondii were detected by the complement fixation test in opossums ( D. virginiana ), rock squirrels ( Spermophilus variegatus ), ringtails ( Bassariscus astutus ) and skunks ( Spilogale gracilis ) on a Mexico City natural reserve (Suzan and Ceballos, 2005). In northern Mexico, using an in-house indirect ELISA, antibodies were detected in two wild rodents ( Sigmodon hispidus and Liomys irroratus ) of five species analysed (Rendón-Franco et al ., 2014 c ). Using the latex agglutination test, parasite antibodies were detected in two wild felid species ( Leopardus wiedii and Lynx rufus ), two wild canids ( Canis latrans and Urocyon cinereoargenteus ), a procyonid ( N. narica ) and an opossum ( Didelphis sp.…”

The continual rise of anthropogenic disturbance of ecosystems has been associated with an increasing incidence of emerging diseases. The largest amount of data on emerging diseases relates to bacterial and viral pathogens, but there is a lack of parasite data, especially from wildlife. Monitoring wildlife parasitic diseases should be considered a priority, especially in high biodiversity regions with strong anthropogenic impacts, like Mexico, where the wildlife/livestock/human interface is associated with increased risk of disease transmission. Mexico belongs to the top-ten megadiverse countries and is located between two biogeographic regions. This situation makes Mexico a favourable region for the spillover of animal pathogens to human beings, causing pandemics, such as the one recently caused by influenza virus A (H1N1). The current state of knowledge of Mexican wildlife parasites is scarce and focuses mainly in Neotropical fauna. Moreover, this knowledge is heterogeneous for different parasite groups, especially concerning their pathologic effects and epidemiology. The goals of this review are to compile information on Mexican wildlife parasites and to identify knowledge gaps in order to stimulate research on pending epidemiological, public health, ecological and pathological areas, and to encourage the creation of more specialized groups from the perspective of the One-Health concept.
