| Babes-Ernst granule | <microbiology> Metachromatic intracellular deposits of polyphosphate found in Corynebacterium diphtheriae when the bacteria are grown on sub optimal media. The granules stain reddish with methylene blue or toluidine blue. (02 Jan 1998) |

| babesia | A genus of tick-borne protozoan parasites that infests the red blood cells of mammals, including humans. There are many recognised species, and the distribution is world-wide. (12 Dec 1998) |
| Babesia argentina | A species of protozoa that is a cause of bovine babesiosis. Ticks of the genera boophilus, rhipicephalus, and ixodes are the chief vectors. (12 Dec 1998) |
| Babesia berbera | A species of protozoa that is a cause of bovine babesiosis. Ticks of the genera boophilus, rhipicephalus, and ixodes are the chief vectors. (12 Dec 1998) |
| Babesia bigemina | Species that is a cause of bovine babesiosis, transmitted by Boophilus ticks. (05 Mar 2000) |
| babesia bovis | A species of protozoa that is a cause of bovine babesiosis. Ticks of the genera boophilus, rhipicephalus, and ixodes are the chief vectors. (12 Dec 1998) |
| Babesia caballi | Species that is a cause of equine babesiosis in many parts of the world, including the southeastern U.S.; vector ticks are species of Dermacentor, Hyalomma, and Rhipicephalus. (05 Mar 2000) |
| Babesia canis | Species found in dogs, wolves, and jackals in many tropical and subtropical areas of the Americas, Europe, Asia, and Africa; it is most pathogenic in dogs, causing mild to severe canine babesiosis, the severest disease occurring in dogs imported into areas where the disease is enzootic; the most important vector is Rhipicephalus sanguineus. (05 Mar 2000) |
| Babesia divergens | Commonest species of Babesia in western and central Europe, causing a disease of cattle similar to that produced by Babesia bovis; vector tick is Ixodes ricinus; it has caused human babesiosis in splenectomised individuals in France, Ireland, Scotland, Croatia, Georgia, a part of the former Soviet Union, and Sweden; also found in reindeer. (05 Mar 2000) |
| Babesia equi | Species that occurs in horses, mules, donkeys, and zebras; it has a geographic distribution similar to that of Babesia caballi, but is smaller and more pathogenic, causing equine babesiosis. (05 Mar 2000) |
| Babesia felis | Species found in domestic and wild members of the cat family, chiefly in Africa and India, causing babesiosis less severe than that caused by Babesia canis. (05 Mar 2000) |
| Babesia gibsoni | Species that infects dogs, wolves, and jackals, chiefly in India, Sri Lanka, and China, and is smaller than Babesia canis; only slightly pathogenic for the natural host, the jackal, but highly pathogenic in the dog. (05 Mar 2000) |
| Babesia microti | A malaria-like protozoan naturally parasitizing certain rodents (Peromyscus and Microtus spp.) in North America; a number of human cases have been reported from Nantucket and Martha's Vineyard islands and nearby coastal New England. The local tick vector is Ixodes dammini, whose numbers and infection levels have greatly increased in recent years with the increase in the deer population, which serves as an abundant blood source for I. Dammini. See: Borrelia burgdorferi. (05 Mar 2000) |
| Babesia motasi | Species that causes acute or chronic disease of sheep and goats in southern Europe, Africa, the Middle East, the area formerly known as the U.S.S.R., and other areas; transmitted by ticks of the genera Rhipicephalus, Haemaphysalis, and Dermacentor. (05 Mar 2000) |
| Babesia ovis | Species described from sheep and goats in many tropical and subtropical areas of the eastern hemisphere as a cause of icterohematuria; it is smaller and less pathogenic than Babesia motasi, and immunologically distinct. (05 Mar 2000) |
