BACKGROUND: Vector-borne diseases of dogs in Australian Aboriginal communities are relatively unexplored. These dogs represent a unique group with variable ecto- and endo-parasitic burdens, nutritional stresses and a general lack of veterinary intervention. We investigated haemoprotozoal and bacterial pathogen prevalences in relation to erythrocyte and platelet numbers in dogs from North-West New South Wales (N-W NSW) and the Northern Territory (NT; Central Australia). METHODS: Real-time PCR (qPCR) amplification of Anaplasma platys, Babesia vogeli, Mycoplasma haemocanis, Candidatus Mycoplasma haematoparvum and Bartonella spp...

Babesia bovis, a parasite infecting cattle and buffalo, continues to spread throughout the developing world. The babesial vaccine was developed to be a sustainable alternative treatment to control the parasite. However, genetic diversity is a major obstacle for designing and developing a safe and effective vaccine. The apical membrane antigen 1 (AMA-1) is considered to be a potential vaccine candidate antigen among immunogenic genes of B. bovis. To gain a more comprehensive understanding of B. bovis AMA-1 (BbAMA-1), three B...

This survey was conducted in four Brazilian cities, from three federative units (Pernambuco, Minas Gerais, and Federal District), representing different socioeconomic settings, to determine the presence of antibodies to or antigens and DNA of selected pathogens in privately owned dogs. From January to April 2015, blood and serum samples were collected and assayed using different tests. In particular, antibodies to Anaplasma spp., Borrelia burgdorferi sensu lato, and Ehrlichia spp., and antigens of Dirofilaria immitis were detected using a rapid enzyme-linked immunosorbent assay, whereas antibodies to Babesia spp...

Wild animals, especially canids, are important reservoirs of vector-borne pathogens, that are transmitted by the ticks and other bloodsucking arthropods. In total, 300 red foxes (Vulpes vulpes), shot by the hunters in eastern and northern Slovakia, were screened for the presence of vector-borne pathogens by PCR-based methods Blood samples were obtained from nine red foxes and tissue samples originated from 291 animals (the liver tissue samples from 49 foxes and spleen samples from 242 red foxes). Babesia vulpes and haemotropic Mycoplasma species were identified by amplification and sequencing of 18S rRNA and 16S rRNA gene fragments, respectively...

Babesia canis is the predominant Babesia species in dogs in Europe and is responsible for a severe and fatal disease. An increase in global pet tourism and a widening of the geographic distribution of the tick vector has led to the emergence of infections in areas where previously only imported cases have been reported. Due to the potential for rapid and serious disease progression, direct parasite detection by stained blood smears and light microscopy or DNA-based methods have traditionally been used for the diagnosis of acute infections...

Cultured Babesia bovis and Babesia bigemina were recovered from liquid nitrogen storage nearly 30 years after they were cryopreserved. Four cattle were compared as donors of erythrocytes and serum for microaerophilous stationary phase (MASP) cultures for recovery of B. bigemina. Erythrocytes and serum from only one (#913) of the four animals supported growth of B. bigemina. Two B. bigemina (frozen in 1986 and 1987) and two B. bovis (both frozen in 1986) cryostocks were recovered from liquid nitrogen storage and all four recovered and thrived in #913 erythrocytes and serum...

Babesiosis is an emerging tick-transmitted zoonosis prevalent in large parts of the world. This study was designed to determine the rates of Babesia microti infection among small rodents in Yunnan province, where human cases of babesiosis have been reported. Currently, distribution of Babesia in its endemic regions is largely unknown. In this study, we cataloged 1672 small wild rodents, comprising 4 orders, from nine areas in western Yunnan province between 2009 and 2011. Babesia microti DNA was detected by polymerase chain reaction in 4·3% (72/1672) of the rodents analyzed...

Babesia canis and Dirofilaria immitis are emerging and geographically overlapping vector-borne pathogens in dogs. Infection with B. canis leads to acute-phase response (APR) that can be mild to severe and results in either non-complicated or complicated forms of the disease. The aim of this study was to determine whether acute B. canis infection is more severe in dogs with underlying asymptomatic D. immitis infection. Dogs of both sexes, different ages and breeds, with naturally occurring mono-infections with B...

The goal of the study was to design a single tube PCR test for detection and differentiation of Babesia species in DNA samples obtained from diverse biological materials. A multiplex, single tube PCR test was designed for amplification of approximately 400 bp region of the Babesia 18S rRNA gene. Universal primers were designed to match DNA of multiple Babesia spp. and to have low levels of similarity to DNA sequences of other intracellular protozoa and Babesia hosts. The PCR products amplified from Babesia DNA isolated from human, dog, rodent, deer, and tick samples were subjected to high-resolution melting analysis for Babesia species identification...

BACKGROUND: Transfusion-transmitted babesiosis (TTB) has been rapidly increasing in incidence since the beginning of the 21st century. Asymptomatic individuals with Babesia infection are able to donate blood in the United States because of the lack of specific blood donation testing. Blood products collected in Babesia-endemic areas are distributed nationally; thus, clinicians in nonendemic states may fail to include babesiosis in the differential diagnosis of a patient who had a recent transfusion history and a fever of unknown origin...

Babesiosis is a globally important zoonotic disease caused by tick-borne intraerythrocytic protozoan of the genus Babesia (phylum apicomplexa). In China, there are five species that infect cattle buffalo and cause great economic loss, which include Babesia bigemina, B. bovis, B. major, B. ovata, and B. orientalis. Among them, B. orientalis is the most recently identified new Babesia species epidemic in China. This review summarized the work done in the past 33 years to give an overview of what learned about this parasite...

The intracellular parasites Babesia microti and Babesia duncani can be transmitted by blood transfusion and cause severe life-threatening hemolytic anemia in high-risk patients, including those with sickle cell disease. The rarity of the diagnosis, as well as its similar clinical presentation to delayed hemolytic transfusion reaction, may lead to a delay in diagnosis, as well as inappropriate treatment with steroids or other immunosuppressive agents. The morbidity caused by this disease in especially vulnerable populations justifies the need for a universal blood-screening program in endemic areas...

Babesia microti, a zoonotic intraerythrocytic parasite, is the primary etiological agent of human babesiosis in the United States (US). Human infection ranges from subclinical illness to severe disease resulting in death, with symptoms related to host immune status. Despite advances in our understanding and management of B. microti, incidence of infection has increased in the US. Therefore, research focused on eradicating disease and optimizing clinical management is essential. Herein, we review this remarkable organism with emphasis on the clinical, diagnostic, and therapeutic aspects of human disease...

Host cell invasion is the only step where Babesia parasites are extracellular, and their survival is menaced during this step. Therefore, interfering with this critical stage is a target for an anti-Babesia intervention strategy. In this regard, recombinant protein encoding Babesia divergens Erythrocyte Binding Protein (BdEBP) was produced in Escherichia coli in the current study, and its antiserum was prepared in mice for further molecular characterization. Western blotting and indirect fluorescent antibody test (IFAT) revealed the specific reaction of the anti-rBdEBP serum with a corresponding authentic protein of B...

Babesia spp. are globally distributed tick-borne protozoan parasites that infect the red blood cells of a wide range of vertebrate hosts, including humans. Diagnosis of babesiosis is often impeded by the transient presence of the parasites in peripheral blood, as well as by their pleomorphic nature. Given the reports of an expanding and, in some cases, sympatric geographical distribution of Babesia canis and Babesia vogeli in dogs and associated vectors, in Europe, the development of time-efficient and cost-effective diagnostic tools to detect and differentiate these two species is warranted...

Lyme borreliosis is associated with memory deficits. While this may be related to cerebral infection by Borrelia bacteria, it may also be caused by concomitant co-infection by Babesia protozoa. The anti-malarial artemisinin-derivative artesunate has been shown to be effective against a number of Babesia species and to have efficacy against human cerebral malaria. We hypothesised that concomitant administration of artesunate in Lyme borreliosis patients would help alleviate the severity of self-reported short-term memory impairment...

The development of gene manipulation techniques has been reported in many protozoan parasites over the past few years. However, these techniques have not yet been established for Babesia gibsoni. Here, we report for the first time, the successful transient transfection of B. gibsoni. The plasmid containing the firefly luciferase reporter gene (pBS-ELA) was transfected into B. gibsoni by an AMAXA 4D Nucleofector™ device. Transfection using program FA113 and Lonza buffer SF showed the highest luciferase expression...

Babesiosis is an emerging tick-borne disease transmitted by the hard tick Ixodes scapularis, which also transmits Lyme disease. Better gradation of prognostic indicators are needed to determine which patients may develop serious complications requiring hospitalization, and to provide early guidance on appropriate therapy. In this study, we evaluated 128 patients with smear or real time polymerase chain reaction-confirmed Babesia microti infections over a period of 16 years. Patients with asplenia or immunocompromising conditions were more likely to have severe infection (P < 0...
