Occurrence of antibodies against Leptospira spp in dogs from Teresina, Piauí, Brazil

Abstract

A leptospirose é uma doença sistêmica causada por bactéria Leptospira spp. que afeta seres humanos, animais domésticos e selvagens. O presente trabalho investigou a presença de anticorpos anti-Leptospira spp. na população canina da cidade de Teresina-Piauí, e os respectivos sorovares predominantes. Amostras de sangue de 425 cães foram coletadas no Centro de Controle de Zoonoses de Teresina, no período de julho de 2010 a janeiro de 2012, e submetidas à prova de Soroaglutinação Microscópica (SAM). Este estudo encontrou uma taxa de infecção média com 17,41% (IC 95%; 13,8 – 21,0) e 11 sorovares reagentes, sendo os prevalentes Canicola (18,9%), Autumnalis (16,2%), Icterohaemorrhagiae (12,1%) e Butembo (12,1%). As questões levantadas neste estudo indicam a ocorrência de infecção por Leptospira spp em cães da cidade de Teresina-Piauí, Brasil.

Evidence of exposure to Leptospira spp. in dogs at a zoonosis control center in Brazil

“…Lower seroprevalences than the current results were reported by Oliveira et al (2012), Paz et al (2015) and Silva et al (2017), who found seroprevalences ranging from 17.41% to 53.8% in dogs from ZCC in Brazil.…”

“…in dogs from zoonosis control centers. Among them are the serological surveys of Oliveira et al (2012), Paz et al (2015) and Silva et al (2017), which reported seroprevalences ranging from 17.41 to 53.8%, and the molecular genetic studies by Meira et al (2011) and Oliveira et al (2012) reporting 4% and 7.7% positive results for Leptospira spp. in blood samples, respectively.…”

Cross-sectional survey for canine leptospirosis in an Atlantic Rainforest area of the semiarid of Paraíba state, Northeastern Brazil

“…The predominance of the serogroup Icterohaemorrhagiae is not a common finding when compared to studies carried out in recent years in other regions of Brazil. In the Southern region, the most common serogroups were Canicola and Autumnalis (Morikawa et al 2015, Oliveira et al 2016, Hafemann et al 2018, Pinto-Ferreira et al 2019, in Minas Gerais the serogroups Autumnalis, Tarassovi, Canicola and Grippotyphosa (Castro et al 2015), in Pará, Canicola, Semaranga and Icterohaemorrhagiae (Paz et al 2015), and in Piauí, the serogroups Canicola, Autumnalis and Australis were the most frequent (Silva et al 2017a).…”
