serological survey of selected pathogens of free-ranging foxes in southern argentina, 1998--2001.a serological survey was conducted in the patagonia region of argentina to estimate the prevalence of nine disease agents within the populations of free-ranging culpeo (dusicyon culpaeus) and grey (dusicyon griseus) foxes. the disease agents were aujeszky's disease virus (adv), brucella, canine adenovirus (cav), canine distemper virus (cdv), canine parvovirus (cpv), encephalitozoon cuniculi, leptospira, neospora caninum, and toxoplasma gondii. a total of 84 foxes were sampled (28 culpeo and 56 g ...200415861875
potential existence of a sylvatic cycle of taenia ovis krabbei in patagonia, deer (cervus elaphus) were introduced in southern latin america about a century ago and characteristics of the invasion raise concerns over their epidemiological role for various diseases. we report on the possible occurrence of taenia ovis krabbei established in a sylvatic cycle in patagonia. hook characters, size, appearance, and location of a cysticercus from a wild red deer are consistent with taenia ovis ovis or t. o. krabbei. although it is not possible to differentiate between t. o. o ...200616289565
epidemiological studies on intestinal helminth parasites of the patagonian grey fox (pseudalopex griseus) in tierra del fuego, patagonia argentina.the present work was performed to study the intestinal helminths of the patagonian grey fox (pseudalopex griseus) and to obtain information about its possible role in the sylvatic life cycle of echinococcu granulosus in tierra del fuego, patagonia argentina. eighty-one foxes were captured and subject to post-mortem analysis. thirty-one foxes (38.3%) harboured helminths. a total of six helminth species were recovered. only one adult of e. granulosus was found in the studied samples. the current s ...200616414190
detection of leishmania dna in wild foxes and associated ticks in patagonia, argentina, 2000 km south of its known distribution area.zoonotic visceral leishmaniasis (zvl) is a vector-borne disease affecting humans and other mammals and caused by the protozoan parasite leishmania (leishmania) infantum (syn. l. chagasi), belonging to the l. donovani complex. the regions in northern argentina (above 32 °s) are its southern distribution limit in south america.201627125871
management of protected areas and its effect on an ecosystem function: removal of prosopis flexuosa seeds by mammals in argentinian drylands.the ecological function of animal seed dispersal depends on species interactions and can be affected by drivers such as the management interventions applied to protected areas. this study was conducted in two protected areas in the monte desert: a fenced reserve with grazing exclusion and absence of large native mammals (the man and biosphere ñacuñán reserve; fr) and an unfenced reserve with low densities of large native and domestic animals (ischigualasto park; ufr). the study focuses on prosop ...201627655222
first isolation of leptospira interrogans from lycalopex griseus (south american gray fox) in argentina shows new mlva identify carriers of leptospira spp. in argentina, wild animals were trapped in buenos aires province during three nights, capturing 12 didelphis albiventris (white-eared opossum), six chaetophractus villosus (big hairy armadillo), five lycalopex griseus (south american gray fox), and two conepatus chinga (molina's hog-nosed skunk). all were tested by microscopic agglutination test, and five (two gray foxes, two armadillos, and one skunk) were positive for leptospira interrogans serovars cani ...201323307384
fleas and ticks in carnivores from a domestic-wildlife interface: implications for public health and wildlife.fleas and ticks are parasites of wild and domestic mammals, and can be vectors of several pathogens. in rural areas, domestic carnivores such as the domestic dog (canis lupus familiaris l.), may act as a "bridge" between natural areas and human settlements where ectoparasites can be used as a metric of such link. the aim of this study was to identify fleas, ticks, and rickettsia spp., collected from domestic and wild carnivores in a natural reserve and surrounding human settlements in central ch ...201627539151
diet, dietary selectivity and density of south american grey fox, lycalopex griseus, in central chile.the south american grey fox (lycalopex griseus) is a canid widely distributed in southern south america, however some aspects of its biology are still poorly known. we studied the diet and density of l. griseus in the lago peñuelas biosphere reserve, in central chile. the trophic niche breadth was b = 6.16 (bsta = 0.47) and prey diversity was h ' = 2.46 (hmax' = 3.17, j' = 0.78). the highest proportions of prey consumed in the diet were oryctolagus cuniculus (52.21%) and other mammals (32.78%). ...201728262006
comparison of chemical immobilization methods in wild foxes (pseudalopex griseus and pseudalopex culpaeus) in chile.we immobilized individuals of two species of free-ranging south american foxes, including 28 chilla foxes (pseudalopex griseus; 13 males and 15 females) and five culpeo foxes (pseudalopex culpaeus; four males and one female). animals were trapped and chemically immobilized with ketamine and medetominide (k-m), ketamine and xylazine (k-x), or tiletamine-zolazepam (z). heart and respiratory rates, hemoglobin oxygen saturation (spo2), rectal temperature, and palpebral and anal reflexes were measure ...201020966271
sarcoptic mange in a south american gray fox (chilla fox; lycalopex griseus ), chile.mange, a prevalent disease of dogs in chile, is also a serious threat to wildlife. we report a case of sarcoptic mange in a south american gray fox or chilla fox ( lycalopex griseus ). further research is needed to understand the impact of mange in wildlife populations.201627310169
