“…Furthermore, one vertebrate host may be infected by several different piroplasmid species, and likewise "vertebrate host specificity" is not a reliable taxonomic criterion. Currently, numerous parasite species are usually found in a single animal species by molecular methods, and the differentiation of the parasite species by microscopic observation is not always possible (11,12,17,18,22). The mixed infection with other parasites which was observed in our study is in accordance with Rabana et al (20) and Ismael et al (10).…”

Clinical, haematological, and biochemical changes induced by naturally occurring babesiosis in dromedary camels were described. Of 258 dromedary camels studied, 34 camels suffered from fever, appetite loss, weakness, depression, and reluctant movement; abortion and/or infertility were also observed. Parasitological blood examinations were performed using Giemsastained blood smears. The clinically affected animals were diagnosed with babesiosis, with 13.17% overall morbidity. Camels that suffered from babesiosis were subjected to haematological and biochemical analyses and the affected group was compared with a control group containing 34 healthy camels. The affected animals showed a highly significant (P<0.001) reduction of the total red blood cell (RBC) count, haemoglobin (HGB) concentration, and mean corpuscular volume (MCV) as well as a highly significant reduction (P<0.01) of haematocrit (HCT) and a significant reduction of (P<0.05) mean corpuscular haemoglobin (MCH). Additional, highly significant increases (P<0.01) in white blood cell (WBC) count and plateletcrit (PCT) percentage were detected. However, other haematological parameters were not significantly altered. There was a very significant reduction (P<0.001) of the blood iron level and a very significant increase (P<0.001) in blood urea nitrogen (BUN) and lactate dehydrogenase (LDH) in the affected camels. Additionally, significant increases in total protein, albumin, γ-glutamyltransferase (GGT), aspartate aminotransferase (AST), and total bilirubin were observed in the affected camels. It was concluded that babesiosis highly affects the haematobiochemical parameters of dromedary camels, including the liver, kidney, and muscle functions. These results represent novel findings concerning natural babesiosis in camels.

“…Two H. japonica ticks carried Babesia genetic variants (Kh-Hj441 and Kh-Hj540, Fig. 2) similar to the only Babesia sequence detected in a Japanese bear (Jinnai et al, 2010), and two other H. japonica ticks (Kh-Hj143, Fig. 2) had sequences similar to those sequences of wild raccoons and American minks piroplasms in Japan (Jinnai et al, 2009;Hirata et al, 2013).…”

“…Em linces-vermelhos (Lynx rufus), considerados reservatórios de C. felis na América do Norte, o parasita apresenta possivelmente uma esquizonia mais limitada, embora existam casos relatados de óbito por cytauxzoonose nesta espécie animal (Blouin et al, 1987;Nietfeld e Pollock, 2002). Embora os espécimes de Lynx rufus possam permanecer cronicamente infectados, eles não são imunes a reinfecções com amostras diferentes de C. felis (Zieman et al, 2018 (Jakob e Wesemeier, 1996;Ketz-Riley et al, 2003;Reichard et al, 2005;Joyner et al, 2007;Criado-Fornelio et al, 2009;Jinnai et al, 2010;Carli et al, 2012;Carli et al, 2014;Kelly et al, 2014;LeClaire et al, 2014;Rassouli et al, 2015;Zaeemi et al, 2015;Alho et al, 2016;Gallusová et al, 2016;Veronesi et al, 2016;Díaz-Regañón et al, 2017;Legroux et al, 2017;Hodžić et al, 2018;Nentwig et al, 2018;Zou et al, 2019).…”

Infecção por Cytauxzoon spp. em felinos domésticos

Cytauxzoon spp. são piroplasmas hemoparasitos que parasitam espécimes da família Felidae. A cytauxzoonose é uma enfermidade caracterizada principalmente por sinais clínicos inespecíficos e súbitos. Tem como reservatórios os felídeos silvestres, no entanto já existem relatos de parasitemia crônica em felinos domésticos. A transmissão ocorre principalmente por vetores como carrapatos na América do Norte; já na América do Sul, Europa e Ásia os vetores são ainda desconhecidos. A patogenia decorre da fase de esquizogonia do parasito em macrófagos que causa obstrução de vasos sanguíneos. O tratamento é baseado nos cuidados de suporte e a combinação terapêutica de atovaquona associada à azitromicina tem demonstrando bons resultados. A profilaxia consiste na restrição do acesso de gatos domésticos em áreas arborizadas que possuam a presença de carrapatos e no uso de repelentes-acaricidas. Com esta revisão de literatura, objetivou-se analisar os aspectos epidemiológicos, clínicos e patológicos que permitam subsidiar o médico veterinário atuar com rapidez em casos suspeitos de cytauxzoonose.
