“…Anaemia and thrombocytopenia were the primary haematological abnormalities in the Babesia gibsoni -infected dogs, consistent with previous reports [ 5 , 20 ]. The average hematocrit was 28.7%.…”

“…The average hematocrit was 28.7%. About 86.9% of the dogs had anaemia, similar to Liu’s [ 20 ] survey of 60 client-owned dogs. However, the severe anaemia in this study was only approximately 20%, much less than in Liu’s study.…”

“…Therefore, a correct diagnosis before treatment is crucial. According to previous studies [ 5 , 20 ], B. gibsoni -infected dogs had various clinical signs, such as fever, vomiting, diarrhoea, pale mucous membranes, splenomegaly, and icterus. The most common hematologic abnormalities were anaemia, thrombocytopenia, hyperglobulinemia, and hyperbilirubinemia [ 20 ].…”

The most common hematologic abnormalities were anaemia, thrombocytopenia, hyperglobulinemia, and hyperbilirubinemia [ 20 ]. In contrast, B. vogeli -naturally infected dogs generally showed asymptomatic or mild clinical signs [ 21 , 22 ], and a similar finding was also reported in Wang et al [ 23 ].…”

The objective of our study was to survey Babesia infection rates by PCR and tick species on stray dogs to correlate the distribution of Babesia with the distribution of ticks infesting dogs in Taiwan. Three hundred eighty-eight blood samples and 3037 ticks were collected from 388 roaming, and free-ranging owned dogs at residential sites in Taiwan between January 2015 and December 2017. The prevalence of B. gibsoni and B. vogeli was 15.7% (61/388) and 9.5% (37/388), respectively. Most positive B. gibsoni dogs were found in the northern part of the country 56/61 (91.8%), whereas a few were found in the middle 5/61 (8.2%). Babesia vogeli infection rates were 10%, 3.6%, and 18.2% in the northern, central, and southern regions, respectively. Five species of ticks were found: Rhipicephalus sanguineus (throughout Taiwan), Rhipicephalus haemaphysaloides (in the north), Haemaphysalis hystricis (in the north and middle of Taiwan), and Amblyomma testidunarium and Ixodes ovatus (both in the north). None of the dogs in the south were infected with B gibsoni, which correlated with the absence of H. hystricis, a tick recently identified as the local vector for B gibsoni. Babesia vogeli was more equally distributed, coinciding with R. sanguineus, a tick that is present throughout Taiwan. Anaemia was detected in 86.9% of infected dogs; among these dogs, approximately 19.7% showed severe anaemia (HCT < 20). These findings provide useful advice for owners regarding outdoor activities with their dogs and local veterinarians with a regional differential diagnosis of babesiosis in Taiwan.

“…Asymptomatic B. canis infections also seem to be quite common [58]. A significant proportion of B. gibsoni-infected dogs are also subclinical [31][32][33][34]. A description of 58 cases of B. vulpes infections from Spain describes a severe disease, with no mention of asymptomatic infection [19].…”

Babesia species infect a very wide range of mammal hosts across the globe and zoonotic infections are of growing concern. Several species of the Babesia genus infect dogs and some of these cause significant morbidity and mortality. The Apicomplexan parasite resides within the red cell and infections result in direct damage to the host through intra- and extravascular hemolysis. An exuberant inflammatory response by the host to some species of Babesia parasites also result in significant collateral damage to the host. Canine infections have been the subject of much study as the wellbeing of these companion animals is increasingly threatened by the spread of tick vectors and an increasingly mobile dog population. There are no widely available and effective vaccines and effective treatment can be challenging. Understanding disease pathogenesis underlies the development of new treatments. The varying pathogenicity of the various Babesia parasite species that infect dogs offers an opportunity to explore the molecular basis for the wide range of disease caused by infection with this parasite genus. In this review we focus on what has been reported about the clinical presentation of Babesia infected dogs in an attempt to compare the severity of disease caused by different Babesia species.
