“…Apesar existirem poucos estudos sobre as alterações hematológicas, normalmente a maioria os autores citam anemias associadas às Rickettsioses em felinos (Charpentier et al 1986;Buoro et al 1989;Beauϐils et al 1995e 1999, Almosny 1998, Davenport et al 1998, Gaunt 2000, Stubbs et al 2000, Aguirre et al 2004, no entanto neste estudo, anemia ou qualquer outra alteração na série vermelha do hemograma não foram associadas à presença de A. platys nos gatos pesquisados. Santiago (2010) relata que os gatos soropositivos para Ehrlichia canis, também não desenvolveram anemia, mas apresentaram hematócrito aumentado, possivelmente devido à desidratação, que também foi observado por Bouloy et al (1994) e Beauϐils et al (1999).…”

ABSTRACT.-Corrêa E.S., Paludo G.R., Scalon M.C., Machado J.A., Lima A.C.Q., Pinto A. Ehrlichia sp. and Anaplasma platys are Gram-negative micro-organisms, obligate intracellular parasites, residing in cytoplasmic vacuoles of leukocytes and platelets, found in peripheral blood or tissue. Few reports have been made about ehrlichiosis and anaplasmosis in cats in Brazil, which are based on the presence of morulae in leukocytes and platelets, or by detecting antibodies. The objective of this study was to investigate the natural infection with Ehrlichia sp. and A. platys in cats in Campos dos Goytacazes-RJ, by hematoscopia and DNA detection of these agents. Samples of whole blood and serum from 91 cats, regardless of race, gender and age. Blood count, serum biochemistry and PCR using primers for Ehrlichia sp. and A. platys were perfomed. Data from hematoscopia showed 9.89% of morulae only in platelets. The DNA of A. platys was detected in 13.18% of the 91 samples and 44.44% of the positive at hematoscopia. The DNA of Ehrlichia sp. was not detected in any sample. All animals studied did not show clinical signs neither positive laboratory results. The data suggest that domestic cats can serve as potential reservoirs for A. platys as asymptomatic form of related diseases.

“…Feline ehrlichiosis has been increasingly recognized worldwide since the first case due to natural infection was reported in France (Charpentier and Groulade, 1986). There appears to be at least two forms of feline ehrlichiosis or anaplasmosis, one attributed to E. canis , with inclusions in mononuclear cells, and the other to A. phagocytophilum , which is associated with inclusions in neutrophils (Foley et al, 1999; Lappin et al, 2004; Lewis et al, 1975).…”

The ehrlichioses have been subject to increasing interest from veterinary and public health perspectives, but experimental studies of these diseases and their etiologic agents can be challenging. Ehrlichia canis, the primary etiologic agent of canine monocytic ehrlichiosis, is relatively well characterized and offers unique advantages and opportunities to study interactions between a monocytotropic pathogen and both its vertebrate and invertebrate hosts. Historically, advances in tick-borne disease control strategies have typically followed explication of tick-pathogen-vertebrate interactions, thus it is reasonable to expect novel, more sustainable approaches to control of these diseases as the transmission of their associated infections are investigated at the molecular through ecological levels. Better understanding of the interactions between E. canis and its canine and tick hosts would also elucidate similar interactions for other Ehrlichia species as well as the potential roles of canine sentinels, reservoirs and models of tick-borne zoonoses. This article summarizes natural exposure studies and experimental investigations of E. canis in the context of what is understood about biological vectors of tick-borne Anaplasmataceae.

The aim of the present study was to estimate the occurrence of Ehrlichia canis in cats from the semiarid region of Northeast of Brazil. Sera of 101 healthy cats were submitted by Indirect Immunofluorescence Assay (IFA), and considered positive when antibody titers ≥ 40 were obtained. Seroprevalence of 35.6% (36/101) was found, with the following titers: 40 (15 animals); 160 (6); 320 (1); 640 (3), and 2,560 (11). No statistical differences were observed when comparing county of origin, gender, age, breed, and modus vivendi (pet and stray cats), and no ticks were observed in any of the cats. This study revealed exposure to E. canis in cats of the Semiarid Northeast of Brazil. Keywords: Caatinga; ehrlichiosis; feline; hemoparasite; semiarid. ResumoO objetivo do presente estudo foi estimar a ocorrência de Ehrlichia canis em gatos na região semiárida do Nordeste. Soros de 101 gatos saudáveis foram submetidos à Reação de Imunofluorescência Indireta (RIFI), sendo considerados positivos títulos ≥ 40. Soroprevalência de 35,6% (36/101) foi encontrada, com os seguintes títulos: 40 (15 animais); 160 (6); 320 (1); 640 (3) e 2560 (11). Não foram observadas diferenças estatísticas quanto ao município de origem, gênero, faixa etária, raça e modus vivendi (gatos domiciliados e errantes) e não foram observados carrapatos em qualquer um dos animais testados. Este estudo revelou exposição de gatos a E. canis na região semiárida do nordeste brasileiro.
