Apicomplexa tick-borne hemoparasites, including Babesia bovis, Babesia microti, and Theileria equi are responsible for bovine and human babesiosis and equine theileriosis, respectively. These parasites of vast medical, epidemiological, and economic impact have complex life cycles in their vertebrate and tick hosts. Large gaps in knowledge concerning the mechanisms used by these parasites for ge...

Babesiosis is a tick-transmitted disease that causes severe economic losses to the cattle industry in Brazil. Water buffaloes (Bubalus bubalis) are often carriers of Babesia spp., but there are no studies that provide an accurate estimation of this infection in animals raised in regions of endemic stability. This study was conducted to investigate Babesia bovis and B. bigemina infections in 108...

Two TaqMan-based real-time polymerase chain reaction (PCR) assays devised for the detection of two bovine Babesia parasites, Babesia bovis and B. bigemina, were evaluated for their diagnostic utility using cultured parasites and 92 field bovine blood samples collected from cattle living in Brazil. The real-time PCR assays were compared with previously established nested-PCR assays. The detectio...

OBJECTIVE To review the evidence available on the degree and duration of immunity provided by Australian tick fever vaccines against Babesia bovis, B. bigemina and Anaplasma marginale infections in Australia and overseas. BACKGROUND Vaccines containing attenuated strains of B bovis and B bigemina as well as A. centrale grown in splenectomised calves have been used in Australia since 1964 to i...

SOME ASPECTS OF THE EPIDEMIOLOGY OF BABESIA BOVIS IN SANTANA DO LIVRAMENTO, SOUTHERN BRAZIL. Some aspects of the epidemiology of Babesia bovis were studied in Santana do Livramento, Rio Grande do Sul, Brazil by analysing cattle raising practices applied to 101 herds and by diagnosing B. bovis antibodies in cattle of about 11 months old using an enzyme linked immunosorbent assay. Herds with prev...

POT9IE~ER, F . T. & VAN VUUREN, A. S., 1974. The transmission of Babesia bovis using frozen infective material obtained from Boophilus microplus larvae. Onderstepoort J. vet. Res., 41 , .... (1974) Bo~philus microplus larvae infected with Babesia bovis were removed from a susceptible ox approximately 72hours after attachment, triturated and stored in a liquid nitrogen refrigerator with dlm,:thy...

Babesia bovis, un parásito protozoario intraeritrocítico transmitido por garrapatas, es uno de los agentes etiológicos la babesiosis bovina, una enfermedad altamente prevalente en las regions tropicales y subtropicales que causa morbilidad mortalidad significativas el Ganado. Para poder eventualmente comparar genomas cepa virulenta atenuada B. objetivo este estudio fue secuenciar ensamblar borr...

In an outbreak of Babesia bovis in a large herd of Friesian x Malawi Zebu cattle, which occurred after an interruption of intensive dipping, clinical or fatal babesiosis occurred in 54/299 (18.1%) animals which had never been vaccinated, as compared to 9/153 (5.9%) vaccinated animals. Eight of the nine affected vaccinates had been vaccinated more than 27 months previously. Sera were collected e...

A total number of 450 blood samples were collected from 45 different randomly selected cattle herds. Light microscopic examination of blood smears revealed Babesia spp. infection in 4.2%, while 8.9% of blood samples were positive using PCR. Upon multiplex-PCR (mPCR), B. bigemina and B. bovis infections were detected in 37/40 (92.5%) and 3/40 (7.5%) samples, respectively. 530 ticks of 10 Ixodid ...

The availability of a stage-specific Babesia bovis expression profile can facilitate the identification of candidate vaccine antigens. In addition, highly expressed genes during a particular developmental stage may suggest their relevance during that stage. In this study, we generated and validated a custom B. bovis high density oligonucleotide microarray that can be used to examine gene expres...
