“…The commercially available D. immitis antigen tests reliably identify infections with more than one female adult parasite and are nearly 100% specific. Differences in sensitivity exist, especially in cases with low worm burdens and/or low antigenemia (Atkins, 2003;Fernandes et al, 1999). These antigen tests are also used to verify the success of adulticidal therapy and can be performed after five months of the therapy (Fernandes et al, 1999).…”

Heartworm disease is a health problem for dogs and cats, especially in tropical and subtropical coastal regions of the world. Some studies have compared the efficacy of the diagnostic techniques used to detect this parasitosis. Therefore, the aim of this study was to compare parasitological optical microscopy (POM), serological and molecular techniques for diagnosing canine heartworm infection. Samples were collected between July 2015 and April 2016 from 103 dogs in Cabo Frio, RJ, Brazil. The wet fresh blood, thick smears, thin smears and modified Knott’s test were used to detect microfilariae. ELISA (Snap™ 4Dx ® IDEXX) was used to detect antigens and the polymerase chain reaction (PCR) was used to detect DNA and enable sequencing for species differentiation and confirmation. 19.4% of samples were positive according to microscopy. Through PCR, 15.5% of the total were positive. Using ELISA, the positivity rate was 29.1%. Occult heartworm infection was detected in 11.6% of the samples. ELISA sensitivity was shown to be higher than PCR or microscopy (P = 0.001). Sequencing of samples confirmed the presence of Dirofilaria immitis and Acanthocheilonema reconditum . ELISA was more effective for serological diagnosis canine heartworm and should be used in clinical and epidemiological studies.

“…No Brasil, a maior prevalência da infecção nos animais é relatada em áreas costeiras, estando presente, também, distante do litoral (FERNANDES et al, 1999;FERNANDES et al, 2000;SOUZA & LARSSON, 2001;CAVALLAZZI et al, 2002;GARCEZ et al, 2006;SIMÓN et al, 2007) Além disso, a freqüência de viagens para áreas endêmicas e as condições precárias de higiene como destino inadequado do lixo, esgotos a céu aberto e acúmulo de água devem ser considerados (THEIS, 2005;SIMÓN et al, 2005).…”

“…Infecções ocultas (animais amicrofilarêmicos) podem ser causadas por helmintos imaturos em filhotes com menos de seis meses de idade, infecções por um único helminto, infecções com um único sexo de helminto, além de reações imunológicas do hospedeiro contra as microfilárias. Nesses casos, o teste do antígeno é necessário para determinar a situação do cão, a fim de controlar mensalmente a infecção (FERNANDES et al, 1999;SOUZA & LARSSON, 2001;DILLON, 2007).…”

“…The intermediate hosts are mosquitoes from several genera, such as Culex, Aedes and Anopheles. The parasite has a worldwide distribution, and several endemic areas have been described in Brazil 2,3,5,8,10,15,16,18,21,22,36,40 . Canids are the most adapted definitive hosts and are the primary reservoir for parasite transmission, but reports about feline and human infection are becoming more frequent, including in Brazil 4,6,24,33,39,42 .…”

SUMMARYReport of two canine dirofilariosis cases of ectopic location in the state of Rio de Janeiro. This is the first report of erratic migration for this parasitosis in dogs in the state, calling attention to the short period of time between the two cases. The fact that the area is endemic for this parasite, its zoonotic potential and the report of human cases in the state, demonstrates that authorities should be alerted to the control programs of dirofilariosis along with the pathogenic profile of the infections.
