This study aimed to report the prevalence of Babesia canis vogeli in dogs and ticks in the urban and rural areas of Petrolina, Pernambuco. Serum and peripheral blood samples of 404 dogs were tested by indirect immunofluorescence assay (IFA) and by blood smears, respectively. The presence of tick infestation was evaluated, and some specimens were submitted to DNA amplification by polymerase chain reaction (PCR). The presence of antibodies anti-B. canis vogeli was determinate in 57.9% (234/404) of dogs. The direct detection of Babesia spp was obtained in 0.5% (2/404) dogs by visualization of intraerythrocytic forms. Infestation by Rhipicephalus sanguineus sensu lato was observed in 54.5% (220/404) of dogs in both urban and rural areas. DNA of Babesia canis vogeli were obtained by PCR in 6% individual (3/50) and 8.7% of pool of ticks (7/80). The risk factors for the presence of anti-B. canis vogeli antibodies, as determined through the application of logistic regression models (P<0.05), were the following: medium breed size variables (P<0.001); contact with areas of forest (P=0.021); and access on the street (P=0.046). This study describes, for the first time, the confirmation of infection of B. canis vogeli in dogs and ticks in the semiarid region of Pernambuco, Brazil.

The aim of this survey was to determine the seropositivity and risk factors forLeishmania 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.

Investigou-se a prevalência de leptospirose em cães da cidade de Campina Grande, PB, e realizou-se um estudo de fatores de risco para a infecção. Foram examinadas 285 amostras de soro sangüíneo de cães colhidas durante a campanha de vacinação anti-rábica animal, conduzida em setembro de 2003. O diagnóstico da leptospirose foi realizado pela técnica de soroaglutinação microscópica, utilizando-se uma coleção de 22 sorovares. Para a caracterização do sorovar mais provável, levou-se em conta a titulação e a freqüência. A prevalência encontrada foi de 21,4% (IC 95% = 16,8%-26,6%), com maior freqüência dos sorovares autumnalis (7,4%), copenhageni (6%) e canicola (2,1%). A análise de regressão logística multivariada mostrou que os fatores de risco para a leptospirose foram: idade superior a um ano (odds ratio = 3,00; P = 0,006), raça não definida (odds ratio = 4,02; P = 0,011) e ocorrência de enchentes (odds ratio = 2,32; P = 0,039).
