“…In the coastal cities of the state of Bahia, the results were as follows: Ilhéus -no infected dogs detected (CARLOS et al, 2007); Lauro de Freitas -20.3%;and Salvador -20% (LABARTHE et al, 2014). In the coastal cities of the State of Pernambuco, the following results were reported: Itamaracá -49.5% and Recife 36.7% (LABARTHE et al, 2014) or 11.54% (RAMOS et al, 2016). In the largest region, the tropical North, which is where the rainforest comprises approximately 75% of the territory, and on the coastal areas of the state of Pará, including Marajó Island, the largest fluvial-maritime island of the world, heartworms infected dogs at different rates, ranging from 32.5% (FURTADO et al, 2009) to 53.5% (GARCEZ et al, 2006).…”

Dirofilaria immitis (LEIDY, 1856; RAILLET; HENRY, 1911) is a parasite that is widely disseminated around the globe, with a higher prevalence in warm, humid climates. The first report of its occurrence in South America is from 1878 in Brazil. At that time, reports were scarce and difficult to retrieve -therefore, gathering them will facilitate recordkeeping over time. Four databases were searched (Scopus, MEDLINE, LILACS, and PubMed) and the search keywords were "Dirofilaria" or "heartworm" and the countries' names. Four countries lacked reports (Bolivia, Ecuador, French Guiana, and Uruguay) and other three (Suriname, Guyana, and Paraguay) had only old reports. Chile was the only country in which studies were conducted over time, and no infected dogs were registered. For the other six countries (Mexico, Peru, Colombia, Venezuela, Argentina, and Brazil), reports showed that the infection frequency varied over time and with the surveyed area. Therefore, the information indicates that D. immitis is established, and veterinarians must institute preventive programs to optimally care for their patients and protect the health of their families. Keywords: Heartworm. Dog. Prevalence. Diagnostic. ResumoDirofilaria immitis (LEIDY, 1856; RAILLET; HENRY, 1911) é um nematoide de ampla distribuição geográfica, que ocorre com maior frequência em áreas quentes e úmidas do planeta. O primeiro registro de sua ocorrência na América do Sul foi realizado em 1878, no Brasil. Naquela época os registros eram poucos e raramente de fácil obtenção, razão pela qual reuni-los facilitará o acesso a tais informações. Quatro bases de dados (Scopus, MEDLINE, LILACS e PubMed) foram estudadas utilizando-se as palavras-chave "Dirofilaria" ou "heartworm", os nomes dos países da América do Sul e o México. Nenhum registro foi encontrado para quatro países (Bolívia, Equador, Guiana Francesa e Uruguai) e para outros três (Suriname, Guiana e Paraguai) os registros eram antigos. Apenas o Chile é o território onde houve estudos registrados com ausência do parasita. Os outros países (México, Peru, Colômbia, Venezuela, Argentina e Brasil) apresentam registros com frequência variável no tempo ou no espaço. Assim, as informações reunidas indicam que infecções por D. immitis ocorrem na maior parte da América do Sul e no México e que os médicos veterinários devem instituir programas preventivos para garantir cuidados médicos de qualidade aos pacientes e para proteger a saúde destes e de suas famílias.

“…Several filariae of domestic dogs have been reported around the world, such as Brugia pahangi (2) , Dirofilaria (Nochtiella) repens (3) , Dipetalonema dracunculoides (4) , Brugia malayi (5) , and Cercopithifilaria bainae (6) . The latter was recently reported in dogs in the Northeast region of Brazil (7) .…”

“…Regarding the morphology of microfilariae, positive samples for A. reconditum had larvae of typical appearance (7) , with rounded anterior and presence of "tooth," and some of them with a hooked tail ( Figure 2; Table 3). On the other hand, microfilariae of D. immitis were larger, with conical anterior portion and straight tails ( Figure 3; Table 3).…”

Occurrence of Filarid Parasites in Household and Sheltered Dogs in the City of Joinville – Santa Catarina, Brazil

Parasites from the Filariidae family are among the nematodes that can infest dogs. Some may be apathogenic, such as Acanthocheilonema reconditum, and others such as Dirofilaria immitis are potentially zoonotic and may lead dogs to death. Thus, the aim of this study was to perform a survey on filarid infection in dogs with a fixed domicile and wandering dogs temporarily sheltered in the city of Joinville, SC, Brazil. Blood samples from 429 animals were collected from 2015 to 2017 and submitted to screening for microfilariae and/or D. immitis antigens. Our results revealed that twenty-four samples (5.6%) displayed A. reconditum microfilariae and three samples (0.7%) were positive for D. immitis, totaling 27 (6.3%) positive animals for filarid parasites. Additionally, A. reconditum was more prevalent in dogs from shelters, whereas the three D. immitis positive samples were from household dogs that displayed no clinical signs of the presence of parasites. The occurrence of these parasites in dogs from Joinville indicates the importance of differential diagnosis of microfilaria species for the correct clinical management of infected dogs. Our epidemiological information may help the medical and veterinary community of the region regarding clinical suspicion of canine and human heartworm disease, as well as guide preventive actions targeting public and animal health.

Parasitic agents have been associated with keratitis, but a diagnosis of parasitic keratitis has not been commonly made in domestic animals. The purpose of this study was to describe the clinical and histopathological findings in seven dogs with chronic keratitis caused by microfilariae diagnosed in Brazil. All dogs presented with superficial corneal opacities of varying degrees affecting the perilimbal and central regions of the cornea, with other opaque areas appearing as crystalline deposits and corneal vascularization. The lesions were bilateral and were associated with mild-to-moderate conjunctival hyperemia. There was no history of blepharospasm or pruritus, and no subjects presented with epithelial erosions. Corneal biopsy revealed free microfilariae in the corneal stroma, with varying degrees of inflammation and collagen fiber destruction. The microfilariae were also found in skin lesions by skin snip technique. No adult worms were found in these dogs, and no dogs were on heartworm preventative before diagnosis. Monthly doses of oral ivermectin improved ocular and dermal lesions. One dog showed complete remission with the treatment. The species of the microfilariae was not identified.
