ABSTRACT: Vector-borne diseases are currently one of the biggest public health concerns worldwide. Dogs, being the closest companion animals to humans, are considered the main reservoir of some of these diseases in the urban environment. Therefore, the study of the disease behavior in dogs can help to understand the disease affecting human health. Serological and molecular diagnoses of Babesia vogeli, Rangelia vitalli, Leishmania infantum, and other trypanosomatids, were performed by immunochromatographic and PCR assays, respectively, on dogs in a dog shelter located in an Atlantic Forest fragment near the Billings Dam, São Bernardo do Campo, São Paulo-Brazil. Our molecular diagnostic results showed a high prevalence of Babesia vogeli, at 20.9% (17/81). No other protozoan was detected in any of the tests. Determining the prevalence of major vector-borne diseases is essential to establish preventive and control measures for zoonotic diseases in animals kept in shelters, in order to minimize the impact of vector-borne diseases on animal health.

Dogs, being the closest companion animals to humans, are considered the main reservoir of some of these diseases in the urban environment, and studying the behavior of the disease in dogs can help in our understanding of the disease as a whole and of how it integrates within human health (DANTAS-TORRES, 2008; DANTAS-TORRES et al, 2014)
We performed serological and molecular diagnoses of some protozoans with importance to health that are transmitted by different arthropods, such as Babesia vogeli, Rangelia vitalli, and Leishmania infantum, in a dog shelter located in an Atlantic Forest fragment in the influential area of Billings Dam in the Riacho Grande district, São Bernardo do Campo, São Paulo-Brazil

Summary

INTRODUCTION

Vector-borne diseases are one of the biggest public health problems (DANTAS-TORRES, 2008; MAGGI et al, 2019). V.50, n.9, which all clinical signs of the disease are caused by erythrocyte lysis (SOARES et al, 2018; DANTASTORRES et al, 2019) It is transmitted by the tick Rhipicephalus sanguineus sensu lato, which has a cosmopolitan distribution, nesting behavior, and adapts to changes in temperature and humidity (WALKER et al, 2000; MORAES-FILHO et al, 2011; DANTAS-TORRES et al, 2019). The causative agent of canine rangeliosis, is a protozoan piroplasma that infects erythrocytes, leukocytes, and endothelial cells in dogs (CARINE et al, 1914; FIGHERA et al, 2010; MONGRUEL, 2018) It is more common in wild canids because its unique vector, the tick Amblyomma aureolatum, is exclusively found in areas of the Atlantic rainforest where the temperature and humidity conditions are favorable for its development (SOARES et al, 2018; DANTAS-TORRES et al, 2019). We performed serological and molecular diagnoses of some protozoans with importance to health that are transmitted by different arthropods, such as Babesia vogeli, Rangelia vitalli, and Leishmania infantum, in a dog shelter located in an Atlantic Forest fragment in the influential area of Billings Dam in the Riacho Grande district, São Bernardo do Campo, São Paulo-Brazil
