The transmission of Babesia bovis using frozen infective material obtained from Boophilus microplus larvae.
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...
متن کاملPCR-based detection of Babesia bovis and Babesia bigemina in their natural host Boophilus microplus and cattle.
PCR and nested-PCR methods were used to assess the frequency of Babesia bovis and Babesia bigemina infection in Boophilus microplus engorged females and eggs and in cattle reared in an area with endemic babesiosis. Blood and the engorged female ticks were from 27 naturally infested calves and 25 crossbred cows. The frequency of both Babesia species was similar in calves and cows (P>0.05). Babes...
متن کاملThe fine structure of merozoites of Babesia bovis in the gut epithelium of Boophilus microplus.
Electron microscopic studies on merozoites of Babesia bovis in epithelial cells of the gut of Boophilus microplus revealed that the pellicle apparently consists of 3 membranes, and an osmiophilic layer intimately associated with microtubules. Micropores in the pellicle were often associated with micronemes. An unidentified tubular structure extended from the anterior polar ring to the nuclear r...
متن کاملTransovarial transmission efficiency of Babesia bovis tick stages acquired by Rhipicephalus (Boophilus) microplus during acute infection.
The protozoan parasite Babesia bovis, a reemerging threat to U.S. cattle, is acquired by adult female ticks of the subgenus Boophilus and is transovarially transmitted as the kinete stage to developing larval offspring. Sporozoites develop within larvae and are transmitted during larval feeding on a bovine host. This study evaluated the efficiency of B. bovis infection within Rhipicephalus (Boo...
متن کاملProteomic profiling of Rhipicephalus (Boophilus) microplus midgut responses to infection with Babesia bovis.
Differences in protein expression in midgut tissue of uninfected and Babesia bovis-infected southern cattle ticks, Rhipicephalus (Boophilus) microplus, were investigated in an effort to establish a proteome database containing proteins involved in successful pathogen transmission. The electrophoretic separation of midgut membrane proteins was greatly improved by using liquid-phase isoelectric f...
