“…Regarding the diagnosis, the blood smear is the most used method on the veterinary clinical routine to direct identification of morulae in blood platelets. It is a practical, fast and with reduced costs method, with a proper specificity during the acute phase, mainly when peripheral blood and buffy coat are used (DANTAS-TORRES et al, 2006;PINTO et al, 2018). However, it presents reduced sensibility due to low parasitemia, with the possibility to occur false negatives (NAKAGHI et al, 2008;RAMOS et al, 2009).…”

“…The animals affected by A. platys can develop asymptomatic cases or present nonspecific clinical signs, such as anorexia, apathy, pale mucous, hyperthermia and increased lymph nodes (DYACHENKO et al, 2012;ZOBBA et al, 2014;ANDRÉ et al, 2015;NAIR et al, 2016;PINTO et al, 2018). As for the laboratory findings, it is possible to visualize thrombocytopenia, macro blood platelets and anemia (SANTARÉM et al, 2005;FERREIRA et al, 2007).…”

“…A. platys has been reported occasionally in domestic felines in Brazil (CORREA et al, 2011;PINTO et al, 2018;RODRIGUES et al, 2021). The sporadic diagnosis might be related to the following factors: reduced agent's pathogenicity; limitation of knowledge regarding infirmities transmitted by ticks in cats and problems identifying the parasite due to variable parasitemia (STUBBS et al, 2000;ZOBBA et al, 2014;ANDRÉ et al, 2015).…”

“…It is known that felines are less predispose to present ticks when compared to dogs and it is believed that they can present resistance to the development of diseases which the arthropods can transmit (CORREA et al, 2011). The knowledge surrounding diseases transmitted by these parasites in cats is considerably lower than in other species (PINTO et al, 2018).…”

“…Due to the fact that cat is a domestic animal that adapts the most to the human being routine, the number of felines by residence has been increasing each year (PINTO et al, 2018). The Brazilian Institute of Geography and Statistics (2020) estimated that 19.3% of Brazilian domiciles possess at least one cat.…”

Anaplasmose é uma hemoparasitose causada pelo Anaplasma platys, uma bactéria gram-negativa, intracelular obrigatória que parasita as plaquetas do hospedeiro. A infecção ocorre principalmente pela picada do carrapato Rhipicephalus sanguineus e os sinais clínicos, quando presentes, costumam ser inespecíficos, como anorexia, apatia, mucosas pálidas, hipertermia e linfonodos aumentados. Na análise do sangue, o principal achado é a trombocitopenia. Portanto, o objetivo deste trabalho foi descrever um caso de anaplasmose em felino doméstico no município de Pelotas no estado do Rio Grande do Sul, Brasil. A amostra de sangue analisada foi procedente de um felino, adulto, fêmea, e sem raça definida. Na avaliação clínica, foi observado a presença de pulgas e carrapatos. No hemograma, as únicas alterações observadas foram trombocitopenia e eosinofília, e no exame bioquímico não foram detectadas alterações. No esfregaço sanguíneo foram visualizadas estruturas compatíveis com mórulas em plaquetas, característico de Anaplasma platys. A partir do diagnóstico, instituiu-se o tratamento com doxiciclina a cada 12 horas por via oral, durante 14 dias, e para controle dos ectoparasitos foi utilizado ectoparasiticida tópico a base de Selamectina. Ao término do tratamento, foi realizado novo esfregaço sanguíneo, não sendo mais observadas mórulas de A. platys, indicando eficácia do tratamento. Palavras chave: Gatos. Hemoparasito. Diagnóstico.

The infection occurs mainly by the bite of the Rhipicephalus sanguineus tick and the clinical signs, when present, are nonspecific, such as anorexia, apathy, pale mucous membranes, hyperthermia and increased lymph nodes. On the blood analysis, the main finding is thrombocytopenia. Therefore, the aim of this work was to describe a case of anaplasmosis in a domestic feline in the city of Pelotas in the state of Rio Grande do Sul, Brazil. The analyzed blood sample came from a feline, adult, female and without defined race. On the clinical evaluation, it was observed the presence of fleas and ticks. On the hemogram, the only alterations observed were thrombocytopenia and eosinophilia, and in the biochemical exam there were no alterations. On the blood smear there were visualized structures compatible with morulae in blood platelets, a characteristic of Anaplasma platys. Following the diagnosis, the treatment with doxycycline was instituted every 12 hours with oral administration, during 14 days, and for the ectoparasites control an ectoparasiticide based on Selamectine was used. At the end of the treatment, a new blood smear was performed, no longer being observed morulae of A. platys, indicating the efficacy of the treatment. Keywords: Cats. Blood Parasite. Diagnosis. Blood Platelets.
