parasitology and serology of free-ranging coyotes (canis latrans) in north carolina, usa.coyotes (canis latrans) have expanded recently into the eastern us and can serve as a source of pathogens to domestic dogs (canis lupus familiaris), livestock, and humans. we examined free-ranging coyotes from central north carolina, us, for selected parasites and prevalence of antibodies against viral and bacterial agents. we detected ticks on most (81%) coyotes, with amblyomma americanum detected on 83% of those with ticks. fifteen (47%) coyotes were positive for heartworms (dirofilaria immiti ...201525984773
regional seroreactivity and vector-borne disease co-exposures in dogs in the united states from 2004-2010: utility of canine surveillance.vector-borne disease (vbd) pathogens remain an emerging health concern for animals and humans throughout the world. surveillance studies of ticks and humans have made substantial contributions to our knowledge of vbd epidemiology trends, but long-term vbd surveillance data of dogs in the united states is limited. this seroreactivity study assessed us temporal and regional trends and co-exposures to anaplasma, babesia, bartonella, borrelia burgdorferi, dirofilaria immitis, ehrlichia spp., and spo ...201425325316
prevalence of naturally occurring dirofilaria immitis infection among nondomestic cats housed in an area in which heartworms are determine prevalences of heartworm exposure (ie, positive heartworm antibody test results) and heartworm infection (ie, positive heartworm antigen test results or identification of mature heartworms at necropsy) among nondomestic cats housed in an area in rural north carolina where dirofilaria immitis is known to be endemic and among nondomestic cats housed in areas with a low prevalence of dirofilariasis or in an area considered to be free from heartworms.200516013550

variation of mosquito (diptera: culicidae) relative abundance and dirofilaria immitis (nematoda: filarioidea) vector potential in coastal north an enzootic focus of dirofilaria immitis in coastal north carolina, mosquito populations were sampled june-september 1985 and on several occasions during august-october 1986 and june-august 1987, to identify local vectors and to determine relative abundance and d. immitis infection rates. predominant species collected were anopheles bradleyi king (66.6%), culex salinarius coquillett (15.9%), aedes taeniorhynchus (wiedemann) (8.2%), and aedes sollicitans (walker) (4.9%). population abundance v ...19938096249
relative suitability of aedes albopictus and aedes aegypti in north carolina to support development of dirofilaria immitis.the relative suitability of two colonies established from local strains of aedes albopictus (wilmington and rockingham) and a local (raleigh) and laboratory (liverpool) strain of ae. aegypti to support development of dirofilaria immitis was investigated. high levels of mortality occurred 1-2 days after mosquitoes fed on a heavily microfilaremic (28,617 microfilariae/ml) dog but not when mosquitoes were fed on a dog exhibiting a moderate microfilaremia (3,300 microfilariae/ml). at 15-16 days post ...19892584971
survey for heartworm, dirofilaria immitis, and dipetalonema reconditum (nematoda:filarioidea) in dogs from virginia and north carolina.random-source dogs (n = 100) in virginia and north carolina were surveyed for the microfilariae of dirofilaria immitis. microscopic examination of fresh thin-films and modified knott preparations were made. dirofilaria immitis and dipetalonema reconditum were found in 19% and 6% of the animals, respectively. there was no animal that harbored both species. prevalence was significantly higher in north carolina (28.6%) than in virginia (13.6%) (p less than 0.025). mean pcv was significantly lower ( ...19827200339
