The species of coccidia occurring in cattle and sheep in the South-West of England

Abstract

A series of line drawings of the unsporulated and sporulated oocysts of the species of Eimeria found in cattle and sheep in Britain has been compiled.The incidence of the different species in faecal samples from animals, of which only a minority were known to be suffering from enteritis or diarrhoea, has been recorded. Samples from sheep frequently contained five or six different species among which those that are believed to be pathogenic (E. arloingi, E. crandallis, E. ninaekohlyakimovae) were the most common.The samples from cattle most frequently contained two or three species. E. bovis and E. zuerni, which are associated with acute disease, were the most common.

The prevalence and intensity of infection withEimeria species in sheep in Nyandarua district of Kenya

“…This sediment was suspended in a solution of potassium dichromate (2.5% w/v) and transferred into clean covered petri dishes, which were incubated at room temperature with constant aeration until the oocysts had sporulated. The oocysts were then identified on the basis of the morphological characteristics of the oocysts and sporocysts (Joyner et aL, 1966;Levine, 1973). A total of 50 oocysts were examined for each farm.…”

The seasonal incidence of coccidia infections in trade cattle, sheep, and goats in Nigeria

“…E. faurei in association with E. arloingi has been shown to produce temporary softening of the faeces but with apparent clinical signs of illness, whereas E. ninakohlyakimovae is capable of causing death (8,9). In view of the high incidence of E. faurei and E. ninakohlyakimovae in sheep and goats in Nigeria, it is,reasonable to attribute most of the clinical coccidioses to the presence of these two species, although E. arloingi is pathogenic on its own (5 The text of the paper should be arranged into sections. In general please follow the lay out and style of recent numbers of this journal.…”

Clinical coccidiosis in adult cattle

“…Infection occasionally occurs in calves over 6 months of age or even in adult cattle. Many cattle are sub clinically infected, resulting in considerable economic losses (Joyner et al 1966). It occurs commonly in overcrowded conditions, but also occurs in free-ranging conditions that have congregating areas, such as feed grounds and watering areas.…”
