Ocorrência de leishmaniose tegumentar em cães de área endêmica no Estado do Paraná

Abstract

RESUMO

Presence of antibodies against Leishmania spp. in domestic dogs from Toledo, Paraná, Brazil

“…Large numbers of dogs seropositive for Leishmania spp. have been documented in this state, with a rate of 38.73% (67/173) recorded in the municipality of Umuarama (GERÔNIMO et al, 2014), 18.2% (24/132) in Jussara and Terra Boa (SILVEIRA et al, 1996), 19% (24/126) in Mariluz (LONARDONI et al, 2006), 6.6% (11/169) in Cianorte (CERINO et al, 2010), 45.4% (222/489) in Bela Vista do Paraíso (REIS et al, 2011), and 55.2% (37/67) (ZANZARINI et al, 2005) and 24% (12/50) (PITTNER et al, 2009) in the Maringá region. Such high estimates stress that elevated seropositivity is due to the region's ecosystem and its status as an area endemic for American CL in humans.…”

“…Dogs can harbor high levels of parasitism, favoring infection of sand flies (DINIZ et al, 2008). The role of canines in the CCL chain of infection remains an active area of research; however, it has been observed that in areas endemic for the human form of this disease, dogs are also infected with protozoa (FALQUETO et al, 1986;PITTNER et al, 2009). …”

“…However, this approach has been questioned because in endemic areas, cases of CVL have increased despite continued efforts to control epidemics. Regarding CL, canine euthanasia is not recommended, owing to a lack of studies concerning the actual role of dogs as a reservoir of the disease (WHO, 2010) Clinical manifestations of VL are similar in dogs and humans, and include non-specific signs, such as irregular fever over long periods, anemia, progressive weight loss, and cachexia in its final stages (PUMAROLA et al, 1991). As the infection and disease progress, many dogs exhibit clinical signs including alopecia, scaling and ulcers, weight loss, increased serum liver enzyme activity, and elevated urea and creatinine levels (CIARAMELLA et al, 1997).…”

Leishmaniasis in dogs from recycling centers and from a neighborhood with adjacent forest in an urban area of Londrina, Paraná, Brazil

“…Zulpo et al (2012) and Caldart et al (2015) studied animals from Londrina and found 11.6% (13/112) and 1.2% (3/236) of seropositivity using IFAT method with 1:40 as a cutoff, respectively; the low prevalence of 1.2% found by the authors may be explained because this study population consisted of clinically healthy animals undergoing elective castration surgery. Pittner et al (2009) (CASTRO et al, 2007;PEREIRA, 2005, HOFFMANN et al, 2012. Several phlebotomine species are present in the same State, and the dominant vector species found infected is Nyssomyia whitmani (MEMBRIVE et al, 2004;OLIVEIRA et al, 2000) wich is involved in the transmission of L. (V.) braziliensis; however, L. (L.) amazonensis vectors have never been found in Paraná.…”

Ocorrência de anticorpos contra Leishmania spp., Neospora caninum E Toxoplasma gondii em soros de cães atendidos no Hospital Veterinário da Universidade Estadual de Londrina-Pr

“…O papel do cão na transmissão da LV é bem conhecido, sendo estes animais considerados o principal reservatório da infecção para os humanos (ALVAR; YACTAYO;BERN, 2006). Dentro da cadeia epidemiológica da leishmaniose cutânea o papel do cão é ainda objeto de estudo, no entanto, observa-se que nas áreas endêmicas os cães também apresentam infecção pelo protozoário (FALQUETO et al, 1986;PITTNER et al, 2009).…”
