canine distemper virus in wild felids of costa rica.several highly infectious diseases can be transmitted through feces and cause elevated mortality among carnivore species. one such infectious agent, canine distemper virus (cdv; paramyxoviridae: morbillivirus), has been reported to affect wild carnivores, among them several felid species. we screened free-ranging and captive wild carnivores in costa rica for cdv. between 2006 and 2012, we collected 306 fecal samples from 70 jaguars (panther onca), 71 ocelots ( leopardus pardalis ), five jaguarun ...201626967127
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 ...201627469023
first evidence of canine distemper in brazilian free-ranging felids.serum samples from 19 jaguars (panthera onca), nine pumas (puma concolor), and two ocelots (leopardus pardalis) were collected between january 1999 and march of 2005 and tested for presence of canine distemper virus (cdv). all cats were free-ranging animals living in two protected areas in the brazilian atlantic forest. in addition, 111 domestic dogs from nearby areas were sampled for cdv. our results show the first evidence of cdv exposure in brazilian free-ranging felids. from the 30 samples a ...200919259737
risk factors for exposure to feline pathogens in california mountain lions (puma concolor).the primary challenge to mountain lion population viability in california is habitat loss and fragmentation. these habitat impacts could enhance disease risk by increasing contact with domestic animals and by altering patterns of exposure to other wild felids. we performed a serologic survey for feline pathogens in california mountain lions (puma concolor) using 490 samples from 45 counties collected from 1990 to 2008. most mountain lions sampled were killed because of depredation or public safe ...201323568903
molecular detection of viral agents in free-ranging and captive neotropical felids in brazil.we describe molecular testing for felid alphaherpesvirus 1 (fhv-1), carnivore protoparvovirus 1 (cppv-1), feline calicivirus (fcv), alphacoronavirus 1 (feline coronavirus [fcov]), feline leukemia virus (felv), feline immunodeficiency virus (fiv), and canine distemper virus (cdv) in whole blood samples of 109 free-ranging and 68 captive neotropical felids from brazil. samples from 2 jaguars ( panthera onca) and 1 oncilla ( leopardus tigrinus) were positive for fhv-1; 2 jaguars, 1 puma ( puma conc ...201728677421
factors associated with pathogen seroprevalence and infection in rocky mountain cougars.serological and genetic material collected over 15 years (1990-2004) from 207 cougars (puma concolor) in four populations in the rocky mountains were examined for evidence of current or prior exposure to feline immunodeficiency virus (fiv), feline parvovirus (fpv), feline coronavirus (fcov), feline calicivirus (fcv), canine distemper virus (cdv), feline herpesvirus (fhv), and yersinia pestis. serologic data were analyzed for annual variation in seroconversions to assess whether these pathogens a ...200617092891
