prevalence of canine dirofilariosis in the city of buenos aires and its outskirts (argentina).during the past 10 years, the prevalence of canine dirofilariosis in the city of buenos aires and its outskirts, particularly in the northern and southern areas, has increased significantly. in the present work, studies were carried out in dogs living in the city and in its northern, western and southern outskirts from 1997 to 2001. for this purpose, 782 blood samples were collected and analyzed to determine circulating antigen, processed with the witness merial antigen test. the samples resulte ...200212423937
dirofilariasis in argentina: historical review and first report of dirofilaria immitis in a natural mosquito population.argentina is one of the four south american countries where the presence of dirofilaria immitis is currently confirmed. the objective of this study was to review information on dirofilariasis in the country, and to report our recent findings on mosquito vectors. since the first report of dogs with unidentified microfilariae in 1926, d. immitis was found in seven provinces and canine prevalence ranged 0-71% at local scale. national prevalence was 8% by the end of the 1980s and current information ...200616310953
pcr detection of dirofilaria immitis in aedes aegypti and culex pipiens from urban temperate argentina.dirofilariasis, a mosquito-borne disease of dogs caused by the nematode dirofilaria immitis (leidy; spirurida: onchocercidae), has now become a growing zoonotic concern. based on direct microscopical observation, aedes aegypti (l.) and culex pipiens l. (diptera: culicidae) have been previously incriminated as potential vectors of d. immitis in urban temperate argentina. in this study, an effort was made to provide evidence for this assumption by screening of mosquitoes for d. immitis infection u ...201021072539
epidemiology of canine heartworm in its southern distribution limit in south america: risk factors, inter-annual trend and spatial patterns.this study was aimed at understanding some aspects of the canine heartworm epidemiology in the southern distribution limit of the parasite in south america. with this objective, 19,298 blood samples of owned dogs from 65 localities of 13 municipalities of buenos aires province were tested for dirofilaria immitis circulating microfilariae and/or female antigens. the overall heartworm prevalence was 1.63% by microhematocrit tube technique (n=19,136), 3.65% by modified knott (n=713), and 14.41% by ...201021093157
