“…Actively surveyed Andean foxes (n = 67) were captured with leg‐hold traps (Oneida Victor Soft Catch No. 1.5, USA), anaesthetised with a ketamine‐dexmedetomidine combination, and reversed with atipamezole (Chirife et al ., 2020). Foxes were released at the capture point after microchip implantation and full recovery.…”

Wild and domestic carnivores share ectoparasites, although molecular evidence is lacking. The goals of this study were to describe tick and flea infestation in sympatric free‐ranging dogs Canis lupus familiaris (Linnaeus, 1758) (Carnivora: Canidae) and Andean foxes Lycalopex culpaeus (Molina, 1782) (Carnivora: Canidae) and to determine whether interspecific transmission occurs. Fleas and ticks retrieved from 79 foxes and 111 dogs in the human‐dominated landscapes of central Chile were identified and a subset of specimens characterized by PCR and amplicon sequencing. Each ectoparasite species was clearly associated with a host: abundance and occurrence of Rhipicephalus sanguineus (Latreille 1806) (Acari: Ixodidae) and Ctenocephalides spp. (Siphonaptera: Pulicidae) were significantly higher in dogs than in foxes, whereas the opposite was true for Amblyomma tigrinum (Koch, 1844) (Acari: Ixodidae) and Pulex irritans (Linnaeus, 1758) (Siphonaptera: Pulicidae). Genetic analyses of a subset of ectoparasites revealed that dogs and foxes shared a limited number of nucleotide sequence types, suggesting that the interspecific transmission of these ectoparasites happens infrequently. Data also indicated that the ecological association and biological cycles of ticks and fleas determine the ectoparasite fauna of sympatric carnivores. In conclusion, our study shows that cross‐species transmission should be assessed at a molecular level.

“…For active sampling, leg-hold traps (Oneida Victor Soft Catch No. 1.5, Cleveland, Ohio, USA) or tomahawk-like live traps baited with tuna or chicken were used, and foxes were anaesthetized following previous published protocols [ 25 , 26 ]. Passive surveillance (25 grey foxes and 60 Andean foxes) included foxes admitted to animal rehabilitation centers or road-killed animals.…”

Blood samples of 626 rural dogs, 140 Andean foxes (Lycalopex culpaeus), and 83 South American grey foxes (L. griseus) from six bioregions of Chile spanning 3000 km were screened for Mycoplasma DNA by conventional PCR and sequencing. Risk factors of infection were inferred using Generalized Linear Mixed Models and genetic structure by network analyses. Overall, Mycoplasma haemocanis/Mycoplasma haemofelis (Mhc/Mhf) and Candidatus Mycoplasma haematoparvum (CMhp) observed prevalence was 23.8% and 12.8% in dogs, 20.1% and 7.2% in Andean foxes, and 26.5% and 8.4% in grey foxes, respectively. Both hemoplasmas were confirmed in all the bioregions, with higher prevalence in those where ticks from the Rhipicephalus sanguineus species group were absent. Candidatus M. haematominutum and a Mycoplasma sp. previously found in South American carnivores were detected in one fox each. Although the most prevalent Mhc/Mhf and CMhp sequence types were shared between dogs and foxes, network analysis revealed genetic structure of Mhc/Mhf between hosts in some regions. Male sex was associated with a higher risk of Mhc/Mhf and CMhp infection in dogs, and adult age with CMhp infection, suggesting that direct transmission is relevant. No risk factor was identified in foxes. Our study provides novel information about canine hemoplasmas with relevance in distribution, transmission routes, and cross-species transmission.

“…Active capture of foxes was carried out with leghold traps (Oneida Victor Soft Catch No. 1.5, USA) baited with tuna or chicken, and anesthesia was performed following Chirife et al (2020) and Acosta-Jamett et al (2010) protocols. For passive surveillance, animals admitted to rehabilitation centers or road killed were included.…”
