ticks (acari: ixodida) on wild carnivores in brazil.	the present study reports field data of ticks infesting wild carnivores captured from july 1998 to september 2004 in brazil. additional data were obtained from one tick collection and from previous published data of ticks on carnivores in brazil. during field work, a total of 3437 ticks were collected from 89 cerdocyon thous (crab-eating fox), 58 chrysocyon brachyurus (maned wolf), 30 puma concolor (puma), 26 panthera onca (jaguar), 12 procyon cancrivorus (crab-eating raccoon), 4 speothos venati ...	2005	16082932
rickettsia amblyommii infecting amblyomma auricularium ticks in pernambuco, northeastern brazil: isolation, transovarial transmission, and transstadial perpetuation.	this study investigated rickettsial infection in amblyomma auricularium ticks from the state of pernambuco, northeastern brazil. an engorged female of a. auricularium collected from a skunk (conepatus semistriatus) was sent alive to the laboratory, where the female was found through molecular analysis to be infected by rickettsia amblyommii. this engorged female oviposited, and its offspring was reared through three consecutive generations, always using tick-naïve rabbits to feed the ticks. pcr ...	2013	23705586
domestic, peridomestic and wild hosts in the transmission of trypanosoma cruzi in the caatinga area colonised by triatoma brasiliensis.	the role played by different mammal species in the maintenance of trypanosoma cruzi is not constant and varies in time and place. this study aimed to characterise the importance of domestic, wild and peridomestic hosts in the transmission of t. cruzi in tauá, state of ceará, caatinga area, brazil, with an emphasis on those environments colonised by triatoma brasiliensis. direct parasitological examinations were performed on insects and mammals, serologic tests were performed on household and out ...	2014	25165976

detection of rickettsia bellii and rickettsia amblyommii in amblyomma longirostre (acari: ixodidae) from bahia state, northeast brazil.	studies investigating rickettsial infections in ticks parasitizing wild animals in the northeast region of brazil have been confined to the detection of rickettsia amblyommii in immature stages of amblyomma longirostre collected from birds in the state of bahia, and in immatures and females of amblyomma auricularium collected from the striped hog-nosed skunk (conepatus semistriatus) and armadillos (euphractus sexcinctus) in the state of pernambuco. the current study extends the distribution of r ...	2015	26413074
exposure of free-ranging wild carnivores and domestic dogs to canine distemper virus and parvovirus in the cerrado of central brazil.	human population growth around protected areas increases the contact between wild and domestic animals, promoting disease transmission between them. this study investigates the exposure of free-ranging wild carnivores and domestic dogs to canine distemper virus (cdv) and parvovirus in emas national park (enp) in the cerrado savanna of central brazil. serum samples were collected from 169 wild carnivores, including the maned wolf (chrysocyon brachyurus), crab-eating fox (cerdocyon thous), hoary f ...	2016	27469023
mammalian carnivore occupancy is inversely related to presence of domestic dogs in the high andes of ecuador.	although the andes have long been occupied by people, habitat loss, fragmentation through deforestation, and other human activities such as introduction of invasive species have increased drastically during the past century. the ecuadorian andes are considered a biodiversity hotspot. however, the fauna and threats to the region are poorly studied, and understanding of factors that shape the distribution of species in habitats disturbed by human activities is needed to identify and mitigate regio ...	2018	29489855
clavicle in carnivorans: a forgotten bone.	the clavicle is a bone whose development is related to the versatility of the thoracic limbs in mammals. studies with vestigial structures are scarce and controversial, especially in the order carnivora. the objective of this study was to verify the presence and to investigate the shape and constitution of the clavicle in neotropical carnivores. in order to do this, 108 cadavers of 19 different species were collected dead on highways and were analyzed. the clavicles were submitted to dissections ...	2020	31633876
