“…After the sporulation process, the samples were centrifuged for 10 minutes at a rotation of 595.1 g, and were then placed between a slide and cover slip and observed under a microscope at magnifications of up to 400X (HOFFMAN, 1987). The species were differentiated from each other in terms of the oocyst characteristics of shape, color, size and presence or absence of micropyles and micropylar hoods, along with the morphological characteristics of the sporocysts, in accordance with the parameters of Amarante and Barbosa (1992).…”

The frequency of species of the genus Eimeria in a dairy herd in the municipality of Boa Esperança, Southern region of the State of Minas Gerais was assessed. From 37 females of the Friesian breed aged three to seven months, 259 feces samples were analyzed between May and September 2008. The examinations to quantify oocysts per gram of feces (OPG) and identify Eimeria species were conducted at the Veterinary Parasitology Laboratory of the Federal University of Lavras. Eleven species of Eimeria were identified, namely: E. bovis (23.2%), E. zuernii (22.6%), E. ellipsoidalis (20.3%), E. cylindrica (14.1%), E. subspherica (5.4%), E. canadensis (3.5%), E. alabamensis (2.4%), E. auburnensis (2.4%), E. pellita (2.1%), E. brasiliensis (2%) and E. bukidnonensis (1.9%). E. bovis, E. zuernii and E. ellipsoidalis were the most frequent and the ones with the highest oocyst shedding over time (p < 0.05). Differences in OPG counts were found between most months studied (p < 0.05). The large number of Eimeria species found, in particular E. bovis and E. zuernii, indicates that Eimeria sp. has significant pathogenic potential in dairy cattle in the South of Minas Gerais.

“…For specifi c identifi cation, one hundred oocysts of each species were measured with a Leica LAS light microscope coupled to a computer system. Species differentiation was performed according to shape, color, presence or absence of micropyle and micropilar cap, oocyst size, and morphological characteristics of sporocysts following the criteria established by VERCRUYSSE (1982), AMARANTE & BARBOSA (1992), SOMMER et al (1998), andDAUGSCHIES &NAJDROWSKI, (2005).…”

“…This disease leads to economic losses due to high mortality and morbidity, low growth performance; reduce in productivity and treatment costs (Kaya 2004;Temizel et al 2011). Surveys based on the examination of ruminant faeces have shown that most animals are infected with a wide variety of Eimeria species from an early age (Vercruysse 1982;O'Callaghan et al 1987;Amarante and Barbosa 1992). In sheep, several species of Eimeria have been recognized including E. ahsata, E. bakuensis, E.crandallis, E. faurei, E. granulosa, E. gonzalezi, E. gilruthi, E. intricata, E. marsica, E. ovinoidalis, E. pallida, E. parva, E. punctata and E. weybridgensis.…”

This study was undertaken to determine the prevalence of Eimeria infection in sheep in Rudsar, North of Iran, in period of 1 year (March 2011 to March 2012. The samples (approximately 3-5 grams of faeces) were collected from the rectum of 270 sheep and transferred to the parasitology laboratory. Eimeria species were identified following sporulation of faeces in a thin layer of 2.5 % potassium dichromate for one or 2 weeks at 27°C. Out of 270 faecal samples examined, 170[(63.0 %; 95 % Confidence Interval (CI) 56.9-68.7)] were positive for Eimeria spp. Five species of Eimeria, including E. ahsata, E. ovina, E. crandallis, E. parva and E. ovinoidalis were identified in faecal samples by modified McMaster technique. The most frequent species was E. crandallis. Sheep were considered in four age groups (less than 1 year old, 1-2 years old, 2-3 years old and over 3 years old).The results also indicated that less than 1 year old sheep have greater infection ratio as compare with older animals. Female had significantly higher prevalence of Eimeria than male. Higher infection was seen in females compare to males and in winter compare to summer. Parasitological gross and microscopic examinations revealed Eimeria infection is common in sheep of Rudsar, North Iran.
