“…The disease transmission dynamics are assumed to be frequency dependent. In utero transmission of Bovine Babesiosis is known to have been observed, namely by Yeruham et al (2003), but they first state that vertical transmission is most likely rare and accidental and seems to require actual physiological change to the cattle, so vertical transmission in cattle is unlikely and improbable (Hall et al 1968;Spickler et al 2010). Thus, in our models, we assume that there is no vertical transmission in cattle.…”

“…As stated before, according to Bock et al (2004), Hall et al (1968) and Zintl et al (2005), infected calves are asymptomatic and once recovered (we assume that this is the maturation rate) have natural immunity against reinfection. Since B. taurus cattle are more susceptible to infection by both B. bovis and B. bigemina than B. indicus cattle (Bock et al 1999a;Jonsson et al 2008), perhaps when calves are present it becomes feasible to only vaccinate B. taurus cattle in order to eradicate Bovine Babesiosis.…”

Bovine Babesiosis in cattle is caused by the transmission of protozoa of Babesia spp. by ticks as vectors. Juvenile cattle (<9 months of age) have resistance to Bovine Babesiosis, rarely show symptoms, and acquire immunity upon recovery. Susceptibility to the disease varies between breeds of cattle. Models of the dynamics of Bovine Babesiosis transmitted by the cattle tick that include these factors are formulated as systems of ordinary differential equations. Basic reproduction numbers are calculated, and it is proved that if these numbers are below the threshold value of one, then Bovine Babesiosis dies out. However, above the threshold number of one, the disease may approach an endemic state. In this case, control measures are suggested by determining target reproduction numbers. The percentage of a particular population (for example, the adult bovine population) needed to be controlled to eradicate the disease is evaluated numerically using Columbia data from the literature.

“…A major role for host-protective antibodies in acquired immunity to babesiosis has been proposed. Immunity is transferred passively from immune mothers to their offspring, presumably by antibody in colostrum (Hall 1960, Hall et al 1968). Also the highly susceptible splenectomized calf may be protected from the severe consequences of homologous B.bovis infection by passive immunization with hyperimmune sera from multiply exposed intact animals (Mahoney 1972, Mahoney et al 1979.…”

“…Apesar de utilizar bezerros isentos de anticorpos contra Babesia sp., presumivelmente sensíveis ao parasito (Hall et al 1968); uma quantidade de inóculo superior aos empregados em outros trabalhos (Mangold et al 1992, Böck et al 1997 e, a via subcutânea como local de inoculação, os animais, do presente estudo, não manifestaram clinicamente os sintomas característicos de babesiose (Purnell 1981, Radostits et al 2000.…”
