Babesial infection in the Madagascan flying fox, Pteropus rufus É. Geoffroy, 1803

Babesiae are erythrocytic protozoans, which infect the red blood cells of vertebrate hosts to cause disease. Previous studies have described potentially pathogenic infections of Babesia vesperuginis in insectivor...

Abstract The diagnostic performance of a cocktail formula consisting of two Babesia (B.) bovis recombinant proteins, including spherical body protein 1 (BbSBP-1) and spherical body protein 4 (BbSBP-4), was evaluated in the present study for the global detection of B. bovis infection in cattle and for the differentiation between B. bovis and B. bigemina infections. The efficacy and the practicality of the rBbSBP-1 and rBbSBP-4 cocktail formula for differentiation between the infection caused by both parasites were assessed using indirect enzyme-linked immunosorbent assay (iELISA) with serum samples collected from c...

This study was set to evaluate the presence of EP parasites in domestic donkeys and in wild equids in Israel and the Palestinian Authority (PA). To assess subclinical EP infection in 98 domestic donkeys (Equus africanus asinus), 9 Asiatic wild donkeys (Equus hemionus), 8 zebras (Equus quagga), 7 African wild donkeys (Equus africanus) and 5 mules, were tested using PCR and qPCR. Positive samples were characterized by amplification and sequencing of a 1600 bp fragment of the 18S rRNA gene. Babesia caballi was not detected in any of the animals. Theileria equi was detected in 32% of the donkeys, 89% of Asiatic wild donkeys, 5...

Publication date: Available online 29 August 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Catarina Rosa, Masahito Asada, Hassan Hakimi, Ana Domingos, Madalena Pimentel, Sandra AntunesAbstractBabesia species, etiological agents of babesiosis, a recognized emerging tick-borne disease, are a significant animal and human health concern with a worldwide socio-economic impact. The development of genetic manipulation techniques, such as transfection technology, is pivotal to improve knowledge regarding the biology of these poorly studied parasites towards better disease control strategies. For Babesia ovis, responsible for...

Answer toParasite Case of the Week 558:Plasmodium falciparummalaria,>10% parasitemia. NEGATIVE rapid antigen.Sowhy is the rapid antigen test negative???As noted by our readers, there are many possible reasons for apositive blood smear and negative rapid malaria antigen test (RDT). Here are our options, along with the reasons why each is or isn't a likely explanation in this case:This is babesiosis, and not malaria. This is a very important consideration given the morphologic similarities betweenBabesiaspp. andPlasmodium falciparum.However, the moprhologic features in this case are highly consistent withP. falciparu...

The control of disease is mainly based on chemotherapy and preventing animals from tick infestation and to date no vaccine is available ...

SargisonAbstractPiroplasmosis is caused by tick-borne haemoprotozoa of the genera Theileria and Babesia. These parasitic infections can seriously impact on the health of livestock and production. Piroplasms of multiple species can be present in a single host, but reliable molecular diagnostic tools are needed in order to understand the composition of these complex paras...

Lobo, Alejandro Sánchez-Flores, Estrella Montero Babesiosis is considered an emerging disease because its incidence has significantly increased in the last 30 years, providing evidence of the expanding range of this rare but potentially life-threatening zoonotic disease.Babesia divergens is a causative agent of babesiosis in humans and cattle in Europe. The recently sequenced gen...

In this study, 13-15-months-old Holstein-Friesian steers were immunised with a subunit vaccine as a prime and a modified vaccinia Ankara vector as a boost, both expressing a chimeric multi-antigen (rMABbo – rMVA). This antigen includes the immunodominant B and T cell epitopes of three B. bovis proteins: merozoite surface antigen - 2c (MSA - 2c), rhoptry associated protein 1 (RAP - 1) and heat shock protein 20 (HSP20). Responses were compared with the Babesia bovis live attenuated vaccine used in Argentina (R1A). Eleven weeks after the first immunisation, all bovines were challenged by the inoculation of a virulent B....

Intensive contact between herdsmen and their livestock, together with the use of pastures without fencing, allows contact between wildlife, domestic animals and humans, thus creating ideal conditions for epizoonos...
