Antibody Detection. Diagnosis of Babesia infection should be made by detection of parasites in patients’ blood smears. However, antibody detection tests are useful for detecting infected individuals with very low levels of parasitemia (such as asymptomatic blood donors in transfusion-associated cases), for diagnosis after infection is cleared by therapy, and for discrimination between ...
Quintao-Silva MG, Melo MN, Ribeiro MF. 2007. Comparison of duplex PCR and microscopic techniques for the identification of Babesia bigemina and Babesia bovis in engorged female ticks of Boophilus microplus. Zoonoses and Public Health, [fecha de acceso marzo 27, 2019]; 54: 147-151. DOI: 10.1111/j.1863-2378.2007.01037.x [ Links ] Riek RF. 1964.
The disease is also called Texas fever, redwater, piroplasmosis, or tick fever in cattle. Babesiosis may be caused by six or more species of Babesia that are divided morphologically into large or small types. The major large species is Babesia bigemina, and the major small species is Babesia bovis. The disease is seen primarily in tropical and ...
La infección asintomática por Babesia puede persistir varios meses o años y no provocar síntomas durante toda su evolución en personas sanas, en especial < 40 años.. Cuando es sintomática, la babesiosis suele comenzar después de un período de incubación de 1 a 2 semanas con síntomas inespecíficos como malestar general, fatiga, escalofríos, fiebre, cefalea, mialgia y artralgia.
Babesia show host specificity, allowing many different subspecies of Babesia to emerge, each infecting a different kind of vertebrate organism. While B. bovis and Babesia bigemina prefer to infect cattle in tropical environments, they can infect other animals, such as the white-tailed deer.
フタゴバベシア（ Babesia bigemina ）は、寄生性の単細胞 真核生物で、ピロプラズマの1種。 オウシマダニ(Rhipicephalus microplus)などマダニ類が媒介し、ウシなどに溶血性貧血・血色素尿などを主徴とするピロプラズマ症（ダニ熱）を引き起こす。
Babesia bovis was significantly inhibited by 10 nM epoxomicin, while a 5 nM epoxomicin treatment inhibited the growth of Babesia bigemina, Babesia ovata, Babesia caballi, and Theileria equi. Moreover, in the presence of 50 nM epoxomicin, the growth of B. bigemina and T. equi was completely suppressed.
