Bovine babesiosis is a tick-transmitted disease caused by different species of Babesia. The white yak is a unique yak breed that lives only in Tianzhu in the Tibetan Autonomous County, Gansu Province, in northwestern China. Previous research using the ELISA method has confirmed that the white yak could become infected with B. bigemina. The objective of this study was the molecular detection and...

To develop an ELISA technique for the detection of antibodies against Babesia ovis, the infectederythrocytes were lysed and the supernatant soluble antigen, after sonication and ultracentrifugation of thelysate was used as antigen. Optimal dilution of the antigen was determined by checkerboard titrations, usingpositive and negative control sera. A correlation of 85% was observed between the res...

BACKGROUND Borrelia burgdorferi, the causative agent of Lyme disease (LD), and Babesia, Bartonella, and Ehrlichia species (spp.) are recognized tick-borne pathogens in humans worldwide. Using serology and molecular testing, the incidence of these pathogens was investigated in symptomatic patients from Australia. METHODS Sera were analyzed by an immunofluorescent antibody assay (IFA) followed ...

Rangelia vitalii is a protozoon described from dogs in the south and southeast regions of Brazil. It is phylogenetically related to Babesia spp. that infects dogs, but data on this enigmatic parasite is still limited. The aim of this work was to detect piroplasm species in dogs in the state of Rio de Janeiro, Brazil, by 18S rRNA gene-based PCR assay, restriction fragment length polymorphism (RF...

In this preliminary study, a novel DNA microarray system was tested for the diagnosis of bovine piroplasmosis and anaplasmosis in comparison with microscopy and PCR assay results. In the Dakahlia Governorate, Egypt, 164 cattle were investigated for the presence of piroplasms and Anaplasma species. All investigated cattle were clinically examined. Blood samples were screened for the presence of ...

Babesia gibsoni and Babesia canis are the etiological agents of canine babesiosis, a protozoal hemolytic disease with global significance. Canine babesiosis has been diagnosed by microscopic identification of intra-erythrocytic trophozoites in blood smear, and by serological testing. Here we developed a quantitative fluorescence resonance energy transfer (FRET)-PCR that amplifies a fragment of ...

The objective of this study was to report for the first time infection by Hepatozoon spp. and Babesia spp. in 10 dogs from the city of Cuiabá, State of Mato Grosso, central-western Brazil. A pair of primers that amplifies a 574 bp fragment of the 18S rRNA of Hepatozoon spp., and a pair of primers that amplifies a 551 bp fragment of the gene 18S rRNA for Babesia spp. were used. Six dogs were pos...

BACKGROUND Babesiosis is a haemoparasitic disease of domestic and wild animals caused by species of the genus Babesia. Babesia bigemina, B. bovis and B. divergens are known to be pathogenic in cattle. The disease is transmitted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. Ixodid ticks are vectors in the trans...

Recent publications highlighting autochthonous Babesia canis infection in dogs from Essex that have not travelled outside the UK are a powerful reminder of the potential for pathogen emergence in new populations. Here the authors use electronic health data collected from two diagnostic laboratories and a network of 392 veterinary premises to describe canine Babesia cases and levels of Babesia c...

Combined inoculation of cattle with vaccine strains of Babesia bigemina and Babesia bovis induced lower antibody titers to B. bigemina than to B. bovis (previous study). Three groups of heifers were used to detect if the low antibody level was due to competition between Babesia species: individuals of G1 and G2 were inoculated with 10 million B. bigemina and B. bovis, respectively, and those of...
