Babesia divergens in splenectomised rats

Research in Veterinary Science, 1984
Babesia divergens, from a bovine, was passaged through two gerbils before being injected into splenectomised rats. By repeated passage every three or four days through splenectomised rats higher parasitaemias were gradually obtained. By passage 28 parasitaemias of 60 per cent were recorded.

Inhibition of Babesia divergens in cattle by oxytetracycline

Veterinary Record, 1986
The effects of continuous oxytetracycline administration on the development of parasitaemia of Babesia divergens during both natural and artificial infections were studied. During natural exposure on grazing heavily infested with Ixodes ricinus, seven out of 42 cattle with no previous exposure to tick-borne diseases were injected every four days with a

Acquired Resistance to Babesia divergens in Experimental Calves

The Journal of Protozoology, 1967
SYNOPSIS. One intact and 2 splenectomized calves were infected with Babesia divergens and the persistence of the parasites in the blood was followed by periodic subinoculations into susceptible splenectomized calves. After periods varying from 3–7 years the parasites failed to be demonstrable by this method.

The experimental transmission of Babesia divergens by Ixodes ricinus

Experimental Parasitology, 1963
Abstract A strain of Babesia divergens , previously maintained by needle passage in splenectomized calves, has been transmitted in the laboratory by larvae and on one occasion by nymphs of Ixodes ricinus . The infection appeared to be transmitted most readily by larvae after infection of the previous adult stage. The techniques described could be

Babesia major in Britain: cross-immunity trials with Babesia divergens in splenectomised calves

Research in Veterinary Science, 1976
Splenectomised calves infected with Babesia major were shown to have no resistance to challenge with Babesia divergens; however, initial infection with B divergens provided a good protection against subsequent challenge with B major. It is suggested that this might mean that B divergens would be the dominant and most commonly encountered species in ...

Babesia divergens: Characterization of a 17-kDa Merozoite Membrane Protein

Experimental Parasitology, 1993
Large amounts of viable merozoites were purified from in vitro cultures of Babesia divergens by a two-step sieving procedure. A monoclonal antibody produced against B. divergens merozoites, mAb DG7, stained the merozoite plasma membrane and an intra-parasitic linear organelle in indirect immunofluorescence.

Babesia divergens: cloning of a Ran binding protein 1 homologue

Veterinary Parasitology, 2003
Babesia divergens is an Apicomplexa transmitted to bovines by its acarian vector, the tick I. ricinus. Babesia divergens merozoites have an intraerythrocytic development in the blood of infected mammals. The nucleocytoplasmic transport system in this parasite is not yet characterized and no protein involvement in such transport has been described.

Babesia divergens in splenectomised calves: titration of the infective dose

Research in Veterinary Science, 1977
Two experiments were carried out in which Babesia divergens was titrated in splenectomised calves. In the first experiment, a linear relationship was observed between infective dose (10(5)--10(9)) parasites) and onset of disease. In the second experiment, a similar trend was observed for infective doses of 10(2)--10(6) parasites, but 10(3) parasites ...

Comparative infectivity of Babesia divergens and a zoonotic Babesia divergens-like parasite in cattle.

The American journal of tropical medicine and hygiene, 2006
Babesia divergens-like parasites identified in human babesiosis cases in Missouri and Kentucky and in eastern cottontail rabbits (Sylvilagus floridanus) on Nantucket Island, Massachusetts, share identical small subunit ribosomal RNA gene sequences. This sequence is 99.8% identical to that of Babesia divergens, suggesting that the U.S. parasite may be B.

Babesia divergens: the immunisation of splenectomised calves using irradiated piroplasms

Research in Veterinary Science, 1979
Groups of three splenectomised calves were inoculated with 1 . 2 x 10(10) Babesia divergens-infected erythrocytes irradiated at 24, 28, 32, 36 and 40 kilorads. Control calves were inoculated with 1 . 2 x 10(7) or 1 . 2 x 10(4) non-irradiated parasites. While control animals all experienced severe reactions, animals receiving blood irradiated at 24, 28 ...
