2.2.1. Babesia divergens The first human babesiosis case was caused by B. divergens and it occurred in Croatia (Skrabalo and Deanovic, 1957). Human cases are typically severe, especially in splenectomized individuals. To date, approximately 40 cases have been reported, primarily from France, Ireland, and Great Britain with fewer cases reported from

The American Journal of Tropical Medicine and Hygiene, 2005
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.

Improved disease resistance after Babesia divergens vaccination
Parasitology Research, 1998The efficacy of a new inactivated vaccine against Babesia divergens was evaluated by means of inoculation tests. The infection was initiated by i.v. injection of blood containing 2 x 10(9) living parasites into splenectomized and non-splenectomized calves. Clinical status and hematological parameters were determined.

First report of Babesia divergens in Tunisia
Veterinary Parasitology, 1996Babesia divergens of bovine origin was isolated, for the first time in Tunisia, from a cow of a local breed (Bos taurus) from a locality in the north-west of the country. Gerbils (Meriones unguiculatus) were used for the isolation of the parasite which was inoculated into a splenectomised Friesian calf that developed a babesiosis, thus confirming the ...

Babesia divergens in splenectomised rats
Research in Veterinary Science, 1984Babesia 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, 1986The 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, 1967SYNOPSIS. 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, 1963Abstract 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, 1976Splenectomised 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, 1993Large 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.
