New species of Eimeria (Apicomplexa: Eimeriidae) from the domesticated goat Capra hircus in New Zealand

Abstract

Three new species of the genus Eimeria Schneider, 1875 are described from the faeces of domesticated goats in New Zealand. Orcysts of E. capralis n. sp. are ellipsoidal, 29.2 x 19.7 (25-34 x 17-24) Ixm, with a distinct micropylar cap. The sporocysts are broadly ovoid, the Stieda body is present and the sporocyst residuum consists of many scattered granules. Sporozoites lie lengthwise head to tail in the sporocyst. Orcysts of E. rnasseyensis n. sp. are broadly ellipsoid to ovoid, 22.3 x 17.4 (18-25 x 15-19) ixm, with a distinct micropylar cap. The polar granules are shattered into fine granules, the sporocysts are elongate ovoid and the Stieda body is present. Orcysts of E. charlestoni n. sp. are ellipsoidal, 22.9 x 17.4 (20-25 x 16-19) p~m, with no micropylar cap. Its orcysts are distinctive, with elongate sporocysts containing very prominent refractile bodies.

Coccidiosis of Goats in Florida, USA

“…Samples were then concentrated by the Sheather's sugar flotation technique. Oocysts were differentiated on the basis of oocyst and sporocyst morphology according to the descriptions and illustrations given by [8,9]. Measurements were made using an ocular micrometer.…”

Antiparasitic efficacy of Artemisia absinthium, toltrazuril and amprolium against intestinal coccidiosis in goats

“…The disease in goats is chiefly confined to females and young animals up to 6 months of age (Soliman and Zalat 2003) and has been reported from different states of India viz., Chattisgarh, Tamil Nadu, Patna (Tiwari and Roy 2004;Senthilvel et al 2004;Kumar et al 2005Kumar et al , 2007. A total of 16 species of Eimeria have been reported as cause of caprine coccidiosis (Soe and Pomroy 1992;Smith and Sherman 1994). Prevention of reduced productivity and losses from coccidiosis in young animals depends on maintenance of hygiene and effective treatment to reduce the level of environmental contamination by infective occysts.…”

Toxoplasmaand other protozoan infections of economic importance in New Zealand

“…Fifteen species of Eimeria have been described from goats in New Zealand (Soe 1989) including three previously undescribed species (Soe & Pomroy 1992). Sporadic outbreaks of disease occur but are seldom documented and often complicated by other infections.…”
