Seroprevalence for brucellosis and leptospirosis in dogs from Belém and Castanhal, State of Pará, Brazil

Abstract: Brucellosis and leptospirosis are widely spread bacterial infections and dogs are the most important source of infection and reservoir for diseases. Dogs can disseminate the agents in the environment and transmit them to humans and/or other animals. The objective of this study was assess the occurrence of reactive to antibodies anti-Leptospira spp., Brucella canis and B. abortus in Belém and Castanhal, State of Pará, Amazon, Brazil. A total of 156 samples were randomly collected in the city of Belém and 158 sa… Show more

“…Higher results were obtained by Paz et al (2015) in Pará, PA; Castro et al (2011) in the municipality of Uberlândia, MG; Azevedo et al (2011) in Patos, PB; Lemos et al (2010) in the municipality of Aracajú, SE; Aguiar et al (2007) in the municipality of Monte Negro, RO;and Batista et al (2005) in the city of Campina Grande, PB; who observed, respectively, 17%, 28.4%, 19.74%, 37%, 27.3%, and 21.4% seropositivity. These differences in positivity can be explained by the variety of factors that influence the occurrence of leptospirosis, particularly with regard…”

“…In certain regions, different serotypes of Leptospira are prevalent and are associated with one or more maintenance hosts that act as reservoirs of the agent; reservoirs are usually wild species but may occasionally include companion and production animals (BOLIN, 1996). Dogs can be infected by a wide variety of serotypes; Autumnalis, and Grippotyphosa (AZEVEDO et al, 2011;CASTRO et al, 2011;FERNANDES et al, 2013;LAVINSKY et al, 2012;MASCOLLI et al, 2016;PAZ et al, 2015). Dogs are infected by direct contact with urine and tissues from infected animals, or indirectly by contact with water contaminated with the urine of infected animals (ADLER et al, 2011), and may be used as sentinel of the presence of Leptospira in the environment (GHNEIM et al, 2007).…”

“…The serovar Canicola (21.8%) was the second most frequent. Castro et al (2011) reported a similar finding in a study carried out in the city of Uberlândia, MG. Paz et al (2015), Coiro et al (2011) and Magalhães et al (2007) also reported that the serovar Canicola appeared with the highest frequency. This serovar, whose natural hosts are dogs but which is also found in commercially available vaccines, causes the animal to present moderate clinical symptoms, but with a marked condition of leptospiremia, making it an important source of infection for humans (HAGIWARA et al, 2004).…”

“…Reactivity to Semaranga (serovar Patoc), the second most common serogroup in our study, has been reported incaptive Geochelones spp. And Trachemys scripta (pond slider) (ESTEVES et al, 2005;SILVA et al, 2010).Despite originatingfrom the non-pathogenic and saprophytic Leptospira biflexa, detecting Semaranga has important implications for anthropozoonosis because its presence may stimulate an immune response and trigger crossreactions with other pathogenic serovars (MYERS, 1976;PAZ et al, 2015). This might be the reason why Semaranga and Bataviae serogroups had the highest titers (3200).…”
