“…Reis et al (2011) found 222 (45.4%) seropositive dogs by IIF among 489 examined in the municipality of Bela Vista do Paraíso, Paraná. None of these animals showed characteristic lesions, which contrasts findings by Madeira et al (2000) in the region of Itaipu, Rio de Janeiro, where 37 (11.9%) of 310 dogs participating in a rabies vaccination campaign were positive by IIF. In the present study, 2 (50%) of 4 dogs with ATL lesions were positive by IIF; this variable was significantly associated (p = 0.0138) with the positive IIF result.…”

Seroepidemiology of Leishmania spp. in dogs residing in Telêmaco Borba, Paraná, Brazil

Leishmaniasis is an important metazoonosis caused by protozoa of the genus Leishmania and has a heteroxenic life cycle involving invertebrate and vertebrate hosts. Transmission occurs during the blood meal of infected phlebotomine sand flies in wild species, domestic animals, and humans. The dog is a reservoir for the parasite causing visceral leishmaniasis (VL), whereas in American tegumentary leishmaniasis (ATL), dogs are erratic hosts that are accidentally infected, as in humans. Dogs are considered an important indicator of the parasite and its vectors in the environment, thus highlighting the importance of diagnosis in these animals. This study aimed to assess the seroepidemiology of Leishmania spp. in dogs in the municipality of Telêmaco Borba that were part of a castration campaign. Blood samples from 191 dogs were collected, and their owners were surveyed on various epidemiological variables. Serological analysis was performed using indirect immunofluorescence (IIF) and rapid immunochromatography (DPP®). Screening by IIF identified 13 (6.81%) positive animals, none of which were positive for the DPP® test, which is specific for VL. Statistical analysis of the questionnaire responses indicated a significant association between seropositivity and the presence of stacked or composting leaves in the backyard (p = 0.0498), forest areas (squares, woods, parks) near the residence (p = 0.0015), and poorly healing ulcerated or nodular epidermal lesions in the dog (p = 0.0138). This study revealed the presence of anti-Leishmania spp. IgG antibodies in dogs residing in Telêmaco Borba, suggesting the presence of the parasite and vector in the environment. In addition, the existence of stacked or composting leaves in the backyard, forest areas near the residence, and epidermal lesions in dogs are factors associated with Leishmania spp. infection in pet dogs. ResumoA leishmaniose é uma importante metazoonose causada por protozoários do gênero Leishmania, com ciclo de vida heteroxênico que envolve hospedeiros invertebrados e vertebrados. A transmissão ocorre durante o repasto sanguíneo do flebotomíneo infectado em animais domésticos e silvestres e no homem. O cão é caracterizado como reservatório do protozoário na leishmaniose visceral, já na leishmaniose tegumentar americana é um hospedeiro errático que, assim como o homem, se infecta acidentalmente. O cão ainda pode ser considerado um importante sinalizador da presença do protozoário e dos vetores no ambiente, assinalando assim a importância do diagnóstico nestes animais. Este trabalho teve como objetivo conhecer a soroepidemiologia da Leishmania spp. em cães do Município de Telêmaco Borba que participaram de um mutirão de castração. Foram coletadas amostras de sangue de 191 cães e aplicado um questionário epidemiológico a seus proprietários. A análise sorológica foi realizada pelas técnicas Imunofluorescência Indireta (IFI) e Imunocromatografia rápida (DPP®). A triagem realizada pela IFI revelou 13 (6,81%) animais reagentes, destes nenhum apresentou positiv...

“…Observou-se que dos 53 cães que não apresentavam lesão, 25 (47,2%) tiveram a IFI positiva para LTA. A presença de cães sem lesão e com sorologia positiva em áreas endêmicas tem sido reportada por outros autores 5,11,17,18 . Em inquérito sorológico realizado nos municí-pios de Jussara e Terra Boa, região noroeste do Estado do Paraná, Silveira et al 8 encontraram 18,2% dos cães com sorologia positiva.…”

A leishmaniose tegumentar americana (LTA) é endêmica no norte do Estado do Paraná, Brasil, afetando tanto o homem como os cães. O objetivo deste trabalho foi estudar a ocorrência da doença na população canina em áreas endêmicas de LTA. No período de setembro de 1999 a julho de 2002, foram investigados cães em sete localidades rurais de cinco municípios onde ocorreram casos humanos autóctones da doença, utilizando métodos parasitológicos e sorológicos. Dos 67 cães estudados, 14 (20,9%) tinham lesões sugestivas de LTA, dos quais 3 (21,4%) estavam infectados por Leishmania sp. Trinta e sete (55,2%) cães apresentaram imunofluorescência indireta positiva para Leishmania (Viannia) braziliensis. Os resultados mostram a ocorrência simultânea de leishmaniose humana e canina e indicam a necessidade de estudos adicionais para esclarecer o papel do cão no ciclo de transmissão do parasito nessas áreas.

“…Dogs that were infected by the parasite but exhibited no lesions have been frequently found in endemic areas (Madeira et al, 2000;Santos et al, 2005), suggesting that the presence of asymptomatic dogs for ACL does not indicate the absence of the infection (Barbosa et al, 1999).…”

A survey was carried out to detect American cutaneous leishmaniasis (ACL) among dogs in an area where a human outbreak had occurred in the state of Pernambuco, in northeastern Brazil. Domiciled dogs living in the district of Três Ladeiras, Igarassu were used in the present study. The following procedures were performed: The Polymerase Chain Reaction (PCR) (n = 126); the Immunofluorescence Antibody Test (IFAT) (n = 80); and a parasitological examination to detect amastigote forms of Leishmania sp. in skin lesions (n = 43). Associations between the infection in animals and the clinical and epidemiological factors were analyzed using Fisher's exact test or the Pearson's chi-squared test. In total, 46.8% (59/126) of the samples tested were PCRpositive. Although a higher frequency of positivity was detected among males (46.3 %) and animals aged between 3 and 4 years (50.0 %), no significant associations were recorded for these variables (p> 0.05). Similarly, the clinical signs and aspects related to the environment in which the animal lives did not differ significantly, but differences were recorded for the variable locality. In the IFAT, only 6.2% (5/80) of the dogs were positive and no amastigote forms of Leishmania sp. were detected.
