The geographical distribution of Babesia bovis and Babesia bigemina antibodies in communal herds in northern and eastern Zimbabwe was determined using the ELISA technique. The animals in different herds in the study region had different levels of natural exposure to B. bovis (mean 32%, range 0-79%) and B. bigemina (mean 52%, range 5-92%) infections. The majority of herds (90%) were endemically ...

The study was aimed at determining the cause of the diseases in three horses exhibiting symptoms of fever, ataxia, mucus membrane paleness, haematuria and thrombocytopenia. The PCR technique revealed the presence in the blood of 18S RNA Babesia/Theileria spp. genetic material. DNA amplification using primers RLB F2 and RLB R2 produced 430 bp size products. The sequences of these PCR products de...

Mice injected intravenously with a commercially available extract of Coxiella burnetii prepared for use as the antigen in the complement fixation diagnostic test for Q fever were subsequently resistant to infection with Babesia microti, Babesia rodhaini, and Plasmodium vinckei petteri. The parasites appeared to die inside circulating erythrocytes. Protection was unaffected by exposing the pretr...

A total of 4190 blood smears were collected between January and December 2007 from dogs exhibiting clinical signs of haemoprotozoan infections. On blood smear examination 485 blood smears were found to be positive for various haemoprotozoa and rickettsia. Among the positive cases , the majority of haemoprotozoans identified were Babesia gibsoni 84.9%, followed by Ehrlichia canis 6 %, Hepatazoan...

Outbreaks of tick-borne disease cases in Santa Catarina, Brazil are known, but the presence of the pathogen DNA has never been determined. In this study, the first survey of Anaplasma marginale, Babesia bigemina, and Babesia bovis DNA on blood samples of 33 cattle from an outbreak in Ponte Alta Municipality, Santa Catarina, Brazil, has been carried out. A multiplex PCR detected 54.5% of animals...

The geographical distribution of Babesia equi and Babesia caballi and their tick vectors is discussed. Control of infections with these protozoa is hampered by the lack of a suitable antiprotozoal drug and a reliable serological test. No vaccine is available. Ehrlichia risticii (the causal agent of Potomac horse fever) and E. equi are rickettsial parasites which are difficult to control. Little...

OVERVIEW Babesiosis is a tick-borne protozoan disease caused by parasites of the genus Babesia that belong to the Piroplasmida. The disease is named after the Romanian bacteriologist Victor Babeş. Babesiosis is also known as piroplasmosis (from Latin pirum, meaning 'pear', and plasma, 'image, formation'). INFECTION Babesiosis affects domestic and wild animals and humans worldwide. While the d...

To identify tick-borne pathogens in blood samples from 68 dogs were examined for Babesia, Anaplasma/Ehrichia, Mycoplasma, and Hepatozoon spp. by using a molecular tool. The detection of DNA was performed using specific primers for partial 16S rRNA or 18S rRNA sequence, and amplicon sequences were analyzed. Our investigation detected Babesia gibsoni (26 dogs) and Anaplasma sp. AnHl446 (2 dogs), ...

In Europe, most reported human cases of babesiosis have been attributed, without strong molecular evidence, to infection with the bovine parasite Babesia divergens. We investigated the first known human cases of babesiosis in Italy and Austria, which occurred in two asplenic men. The complete 18S ribosomal RNA (18S rRNA) gene was amplified from specimens of their whole blood by polymerase chain...

Babesiosis is a vector-borne, tick-borne disease of worldwide distribution (Otranto, et al. [1]), caused by protozoa the genus Babesia, infecting both domestic and wild animals (Uilenberg, [2-5]).
