Understanding the genetic variation within a parasitic species is crucial to implementing successful control programs and preventing the dispersal of drug resistance alleles. We examined the population genetics and structure of canine heartworm (Dirofilaria immitis) by developing a panel of 11 polymorphic microsatellite loci for this abundant parasite. In total, 192 individual nematodes were op...

between july and august 2009, a total of two hundred crossbreed dogs in three contiguous littoralprovinces of guilan, mazandaran and golestan were sampled. circulating antigens and/or microfilariae ofdirofilaria immitis were found in 25.5% of dogs in the whole studied area. the highest infection rate wasfound in guilan (51.42%), followed by golestan and mazandaran provinces (15.38% and 7.69%, r...

background: heartworm ( dirofilaria immitis ) is mosquito-borne filarial nematode capable of causing serious cardiopulmonary disease in canines and felines, and pulmonary dirofilariasis in man. this research was conducted with the objectives of determining the incidence and assessing possible risk factors of canine heartworm in the southeast of iran. methods: from october 2012 to september 2013...

background: the sole published data on feline heartworm infection in the philippines was reported four decades ago. the study therefore endeavoured to assess and provide an update on the current status of heartworm infection in domesticated feline species using serologic and parasitological ex-amination methods. methods: a total of 46 males and 54 females cats showing clinical signs of dirofila...

The canine heartworm, Dirofilaria immitis, is among the most important parasites of dogs in United States and worldwide, may cause severe potentially fatal disease. Current diagnostic recommendations rely on serological detection an adult female antigen, visualization microfilariae blood. Therefore, a reliable diagnosis can be only performed approximately six months post-infection. There growin...

A safer, more effective adulticidal treatment and a safe method for reducing microfilaremia and breaking transmission of heartworm disease early in the treatment are needed. The present study evaluated efficacy of ivermectin (IVM) and doxycycline (DOXY) alone or together (with or without melarsomine [MEL]) in dogs with induced adult heartworm infection and assessed the ability of microfilariae ...
