Avaliação da coagulação plasmática e plaquetometria em cães não infectados e infectados experimentalmente com Ehrlichia spp.

Abstract: RESUMOAvaliou-se a ocorrência de distúrbios na coagulação plasmática e na plaquetometria de cães infectados por Ehrlichia spp., durante 15 semanas após o contágio. Doze cães, entre machos e fêmeas, nascidos em estação experimental e com idades entre um e dois anos, foram usados no experimento. Nove cães foram infectados experimentalmente com sangue de cão naturalmente portador de Ehrlichia spp. e três foram mantidos como controle. As alterações na coagulação plasmática não diferiram entre cães infectados e não… Show more

“…The acute stage lasts two to four weeks and has non-specific clinical signs that may include apathy, anorexia, vomiting, fever, ocular and nasal discharge, weight loss, ocular lesions, lymphadenopathy, hepatosplenomegaly, and dyspnea (MOREIRA et al, 2003(MOREIRA et al, , 2005CASTRO et al, 2004;AGUIAR et al, 2007b;ORIÁ et al, 2008;BORIN et al, 2009). Hematological findings in this phase may include normocytic normochromic anemia (MOREIRA et al, 2003(MOREIRA et al, , 2005CASTRO et al, 2004;BORIN et al, 2009) CASTRO et al, 2004;BORIN et al, 2009;XAVIER et al, 2009). Cardiomyocyte injury has been identifi ed in Brazilian dogs naturally infected with E. canis.…”

“…Laboratory fi ndings during the subclinical stage include nonregenerative anemia (MOREIRA et al, 2003(MOREIRA et al, , 2005ORIÁ et al, 2008;BORIN et al, 2009), leukopenia and thrombocytopenia (DAGNONE et al, 2003;BULLA et al, 2004;MOREIRA et al, 2005;ORIÁ et al, 2008;SANTOS et al, 2009;XAVIER et al, 2009). Altered platelet function is likely since dogs may present superfi cial bleeding such as epistaxis and petechia, even when platelet counts and coagulation profi les are within reference ranges (FRANK; BREITSCHWERDT, 1999;MOREIRA et al, 2005).…”

“…According to our data, it seems that levamisole associated with doxycycline does not change the usual profile of anemia, platelet counts, and hematocrit values observed in Ehrlichia-infected dogs. It has been shown that Ehrlichia-infected dogs slowly return to normal numbers of platelets from the seventh week after infection (31). The slow recovery from thrombocytopenia is attributed at least in part to Ehrlichia activation of a factor that inhibits platelet migration from the bone morrow to the peripheral blood, faster platelet death, and production of antibodies against platelets (19).…”
