“…(2013) 26 with dogs naturally infected by Trypanosoma cruzi showed a prevalence of 4.08% in the rural area of the municipality of Patos , located in the semiarid region of the nearby Paraiba State, a significantly lower prevalence in comparison with that found in SJPI (7.7%). The contextualization of the problem and the production of data on these diseases in the municipality of SJPI will bring a better understanding of epidemiological issues and pertinent entomological, political and administrative discussions.…”

SUMMARYChagas disease and the leishmaniases are endemic zoonoses of great importance to public health in the state of Piauí, Brazil. The domestic dog (Canis familiaris) is a major reservoir, host of Trypanosoma cruzi and Leishmania spp. in both urban and rural areas, playing an important role in the transmission of these parasites. The present study evaluated the prevalence of both infectious diseases in dogs of a rural area in the municipality of São João do Piauí, Piauí State. One hundred twenty-nine blood samples were collected for serological assessment: for the leishmaniases, 49 (38%) animals tested positive by the Dual-Path Platform technology (DPP), nine (6%) by the Enzyme-linked Immunosorbent Assay (ELISA), and 19 (14.7%) by the Indirect Fluorescent Antibody test (IFA); while for American Trypanosomiasis, 36 (28%) dogs were reagent by ELISA and 21 by IFA. Of the 129 dogs sampled, 76 were submitted to xenodiagnosis, bone marrow aspiration and skin biopsy to perform parasitological tests whose results showed only one (2.3%) positive skin sample for Trypanosoma caninum and one positive xenodiagnosis for T. cruzi, both results confirmed by molecular assays. Three hundred triatomines of the species Triatoma brasiliensis and 552 phlebotomines - 509 (97%) of the species Lutzomyia longipalpis, were also captured.

“…This value differs from that (22.7%) described by Souza et al (2009), which analyzed the seroprevalence of T. cruzi infection in dogs from Mato Grosso do Sul using IFAT and ELISA. Mendes et al (2013) found a prevalence of 4.08% using IFAT, ELISA and indirect hemagglutination (IHA), in Patos, PB. The higher frequencies could probably be attributed to the predominantly rural survey areas, which are the usual ecotopes of disease vectors.…”

The aim of this survey was to determine the seropositivity and risk factors for Leishmania spp. and Trypanosoma cruzi in dogs in the State of Paraíba, Northeastern Brazil. A total of 1,043 dogs were tested, and the serological diagnoses of Chagas disease (CD) and canine visceral leishmaniasis (CVL) was performed by the indirect fluorescent antibody test (IFAT). Animals that tested seropositive for both diseases (by IFAT) were further subjected to ELISA. Of the 1,043 dogs 81 (7.8%; 95% CI = 6.1-9.4%) tested seropositive for Leishmania spp., while 83 were seropositive for T. cruzi (7.9%; 95% CI = 6.3-9.6%). Simultaneous serological reactions were detected in 49 animals (4.6%; 95% CI= 3.6-6.2%). Semi-domiciled housing (OR = 2.044), free housing (OR = 4.151), and soil (OR = 3.425) and soil/cement (OR = 3.065) environmental conditions were identified as risk factors for CVL seropositivity. The risk factors identified for CD seropositivity were semi-domiciled (OR = 2.353) or free housing (OR = 3.454), and contact with bovine (OR = 2.015). This study revealed the presence of dogs in the Paraíba State seropositive for CVL and CD, suggesting the need for revisiting and intensification of disease control measures through constant monitoring of the canine population.Keywords: Dogs, Leishmania infantum, Trypanosoma cruzi, risk factors, Northeastern region of Brazil. ResumoO objetivo do presente trabalho foi determinar a soropositividade para Leishmania spp. e Trypanosoma cruzi em cães do Estado da Paraíba, Nordeste do Brasil, bem como identificar fatores de risco. Foram utilizados 1.043 cães e, para o diagnóstico sorológico de doença de Chagas (DC) e leishmaniose visceral canina (LVC), foi utilizada a reação de imunofluorescência indireta (RIFI). Animais positivos para ambas as doenças (pela RIFI) foram submetidos ao ELISA. Dos 1.043 cães investigados, 81 foram soropositivos para Leishmania spp., resultando em prevalência de 7,8% (IC 95% = 6,1-9,4%) e, para T. cruzi, 83 (7,9%; IC 95% = 6,3-9,6%) animais foram soropositivos. Quarenta e nove animais (4,6%; IC 95% = 3,6-6,2%) apresentaram sororeatividade mista. Criação semidomiciliar (OR = 2,044), criação solta (OR = 4,151), ambiente de terra (OR = 3,425) e ambiente de terra/cimento (OR = 3,065) foram apontados como fatores de risco para LVC, e criação semidomiciliar (OR = 2,353), criação solta (OR = 3,454) e contato com bovinos (OR = 2,015) para DC. Conclui-se que LVC e DC estão presentes em cães do Estado da Paraíba, o que sugere revisão e intensificação das medidas de controle através do constante monitoramento da população canina.Palavras-chave: Cães, Leishmania infantum, Trypanosoma cruzi, fatores de risco, Nordeste do Brasil.

The state of Paraiba is endemic for CVL and presents confirmed cases of CD in dogs (BRITO et al, 2016;MENDES et al, 2013).

This study aimed to determine the prevalence and risk factors associated with Leishmania spp. and Trypanosoma cruzi infections in dogs presented at veterinary clinics in the city of João Pessoa, Paraíba state, northeastern Brazil. A total of 384 dogs from 34 veterinary clinics were sampled between April 2015 and May 2016. For serological diagnosis of canine visceral leishmaniasis and Chagas disease, the indirect fluorescent antibody test was used. Reactive sera were submitted to a confirmatory test using the S7 ELISA. The seroprevalence of Leishmania spp. was 2.8% (11/384), and that of T. cruzi was 1.5% (6/384). Two animals were positive for both parasites. The variable “access to the street” was identified as a risk factor for Leishmania spp. infection (OR = 4.81; 95% CI = 1.23–18.75). We concluded that a significant proportion of dogs presented at veterinary clinics in João Pessoa are seropositive for Leishmania spp. or T. cruzi infections, and we suggest that greater care be taken with dogs that have access to the street.
