Fatal Intestinal Coccidiosis in a Three-Week-Old Buffalo Calf (Bubalus bubalus)
Abstract The water buffalo (Bubalus bubalus) is important to the economy of several countries, especially in Asia and South America. Little is known regarding the impact of coccidiosis in buffaloes. Cattle and buffaloes are considered to have common species of Eimeria, but critical cross-transmissions have not been made because it is difficult to raise these hosts coccidian free. Clinical coccidiosis was confirmed post mortem in a 22-day-old buffalo calf that died after a 3- to 4-day illness. Oocysts morphologically identical to Eimeria bareillyi were found in the feces and in sections of small intestine. Oocysts were often pyriform, sometimes with asymmetrical sides. The shorter end was flattened and approximately 5–6 μm wide. Unsporulated oocysts in feces were 23.2–29.5 × 16.5–22 μm, with an average of 27.2 × 19.3 μm. Schizonts, gamonts, and oocysts were identified in sections of small intestine where they were located in enterocytes of the jejunum and ileum. No coccidian stages were seen in sections of colon. This is one of the first confirmed cases of clinical coccidiosis in water buffalo.
Re-evaluation of endogenous development of Eimeria bareillyi Gill, Chhabra and Lall, 1963 in water buffalo (Bubalus bubalis)
Abstract Water buffalo (Bubalus bubalis) is important for the economy of Asia, South America and parts of Europe. Coccidiosis is an important cause of neonatal mortality in livestock, including buffalo. Of more than 12 species of Eimeria in buffalo, Eimeria bareillyi is the most pathogenic. There are uncertainties concerning its asexual and sexual development. During a previously reported outbreak of fatal enteritis associated with E. bareillyi in buffaloes in the Netherlands, sections of small intestine were re-evaluated histologically and by transmission electron microscopy (TEM) to seek details of endogenous development. Profuse asexual multiplication occurred in the jejunum and ileum. Light microscopic examination revealed that parasites divided in two (probably endodyogeny) or more organisms. There were two or more generations of morphologically different merozoites; some of these observations were confirmed by TEM. Details of gametogonic development, including oocyst wall formation are provided. Schizogonic and gametogonic development described in the present study can serve as a guide for differential diagnosis of Eimeria species in histological sections of intestines of buffaloes.
