India ABSTRACT During the period of two years i.e. from june-2007 to May 2009 a total number of 2636 goat samples were examined. 528 of these were positive for coccidial infection, the percentage of prevalence being about 20.03%. The present study twelve species of Eimeria from goats were found. Out of twelve species, Nine species are redescribed and three are new species. The commonest was E. arloingi, it was found 15.15% of the total sample examined. Followed by E. crandallis 13.63%, E. parva 12.12%, E. ninakohlyakimovae 11.17%, E. intricata 10.41%,. E. christenseni, 8.90%, E. ahsata 7.57%, E. hirci 6.62%, E. parbhaniensis 5.68%,. Three new species are recorded. E. straightatus 3.97%, E. susheelensis 2.84% and Eimeria leafii 1.32% examined. During the period of two years i.e. from june to May 2009 a total number of 2462 sheep samples were examined. 594 of these were positive for coccidial infection, the percentage of prevalence being about 24.12%. The present study ten species of Eimeria from sheep were found. Out of ten species in sheep eight species are redescribed and two are new species. Eimeria crandallis was the most frequent, being found in 108 out of 594 positive samples 18.18% of the total samples examined. followed by Eimeria parva 15.15%, Eimeria weybridgensis 13.80%, Eimeria ninakohlyakimovae 12.62%, Eimeria intricata 10.26%, Eimeria ahsata 9.25%, Eimeria ovina 6.90%, Eimeria ajantai 5.72%. Two new species are recorded, Eimeria balloonii and Eimeria beedatus. Eimeria balloonii 4.37%, Eimeria beedatus 3.70% of the positives samples examined. KEY WORDS: Eimeria, Coccidia, oocyst, sporocyst, sporozoite INTRODUCTION Coccidian parasites infect the intestinal tracts of animals, and are largest group of protozoa. Eimeria is a genus of apicomplexan parasites that includes various species responsible for the disease coccidiosis. These species cause pathological damage and mortality in poultry, cattle, sheep, goat, pig, rabbit and other animals. The genus Eimeria Schneider, 1975, with more than 1400 species described to date, is the largest genus, and may be the most specious genus of all animal genera. Coccidia have a complex life cycle and other unusual characteristics which have stimulated investigations by increasing number of biologists. The studies of fine ultra structure of coccidia have indicated that they are related to plasmodium, which causes malaria, and to other blood sporozoa. The studies also proves that closer relationship between coccidia and toxoplasma, the organism which causes toxoplasmosis, and to other similar organism, such as Sarcosytis was suggested by these studies. The discovery in 1970 shows that toxoplasma gondii undergoes a cycle of stages in the intestine of cats similar to those of coccidia and is transmissible by oocysts discharged in the feces of cats; the coccidian nature of this organism was proved. The coccidia have enhanced medical as well as veterinary and general biological importance. MATERIALS AND METHODS The material for the study of coccidia of goats and sheep was obtained from various slaughter houses as well as from different fields in and around Beed (M.S.). Different parts of the intestine of slaughtered goats were examined and processed within 4-5 hours after collection. The faecal contents were diluted with distilled water and sieved to remove the large faecal debris. After repeated washing the oocysts were concentrated by centrifugation at 3000 rpm for 10 minutes. The oocysts were then spread out in shallow petri dishes and covered with 2.5% solution of potassium dichromate for sporulation. OBSERVATION AND RESULTS During the present study twelve species of Eimeria are found in goats. Nine species are redescribed and three are new species. The commonest was E. arloingi, it was found in 80 of 528 positive samples, showing a prevalence of 15.15% of the positive samples or 3.03% of the total sample examined. E. ninakohlyakimovae was the fourth found 59 out of 528 positive samples representing 11.17% of the positive samples and 2.23% of the total samples examined.

2 During the study ten species of Eimeria are found in sheep, eight species are redescribed and two are new species. Eimeria crandallis was the most frequent, being found in 108 out of 594 positive samples 18.18% or 4.38% of the total samples. Eimeria ninakohlyakimovae was the fourth found in 75out of 594 positive samples, representing 12.62% of the positive samples and 3.04% of the total samples examined. Description of the oocyst of Eimeria ninakohlyakimovae The oocysts collected from the goats are subspherical with micropyle but without micropylar cap.

3 The oocyst wall is double layered and 2.5µm thick. The outer layer is smooth, yellowish brown in colour, 1.3µm thick. The inner layer is light yellow, 1.2µm thick. The micropyle measures 1µm wide. One or more polar granules are present, the oocystic residuum is absent. The unsporulated oocyst shows the presence of spherical sporoblast which measures about 11 18µm in diameter. The sporocysts are spindle shaped and without stieda body. Sporocystic residuum is present, composed of many scattered granules. Sporozoites are elongate, laying length wise in the sporocyst. Each has a conspicuous refractile globule. The oocysts collected from the sheep are similar in size than that of goat. The oocyst wall is double layered and about 2.2µm thick. The outer layer is smooth and reddish to brown in colour, 1.2µm thick. The inner layer is dark green, 1.0µm thick. Micropyle is present, micropylar cap is absent. Polar granules are present, but the oocystic residuum is absent. The unsporulated oocyst shows the presence of spherical sporoblast measures about µm in diameter. The sporocysts are ovoid and with the small stieda body. Sporocystic residuum is present, composed of many scattered granules. Sporozoites are elongate and with a refractile globule.

5 it was reported by Chhabra and Pande (1991), Jalila et.al (1998), Koudela et.al (1998), Faizal and Rajapakse (2001), Serder et.al (2003), Kumar lalan et.al (2005), Daie et.al (2006), Abdurrahman Gul (2007), Bandra et.al (2007), Sharma et.al (2009). From sheep it was described by Jackson (1934), Christenson (1938), Singh (1963), Shah (1963), Chevailer (1965), Bali (1972), Bawazir (1980), and Nikam (1983). It was also reported by Varghese and Yayabu (1985), O Callaghan et.al (1987), Barutzki et.al (1990), Dasilva et.al (1991), Maingi and Munyua (1994), Balika Ramize (1999), Arslan et.al (1999), Galip Kaya (2004), Fawazia H. Toulah (2007), Gul A (2007), Karl Skirnisson (2007), Mohammad Yakhchali and Eqbal Golami (2008). Other workers like Balozet (1932), Rao and Hiregaudar (1954), Svanbaev (1957), Ray (1961), Bhatia and Pande (1970) described this species without specifying whether the material was from goats or sheep. Comparison of the oocysts from goats and sheep of present author with the previous workers is given in Table No.1 After the observation of dimensions of the various workers it has seen that the oocysts of goats of present author are larger than Shah and Jyoshi (1963), Singh (1964), Nikam (1983) and Jadhav (2002) but smaller in size than Kshirsagar (1976). Present author observed micropyle in this species which was also recorded by Nikam (1983) and Jadhav (2002) but it was absent in the species recorded by Kshirsagar (1976). In present species sporocysts are without stieda body as Kshirsagar (1976), also recorded sporocysts without stieda body while Nikam (1983) and Jadhav (2002) recorded sporocysts with small stieda body. The oocysts of sheep of present author are smaller in size than Christensen (1938), Singh (1963), Rastani (1966), Levine and Ivens (1970), Bhatia and Pande (1970), Bawazir (1980). Nikam (1983). Bawazir (1980) and Nikam (1983) reported a micropyle and also reported by present author. A small stieda body was observed by Nikam (1983) and present author while it was absent in the species recorded by Bawazir (1980).
