“…Also, (Yakhchali and Golami, 2008) founded that sex affects the infection rate of ovine coccidiosis. On the other hand, our finding disagrees with (Lakew and Seyoum, 2016;Daugschies and Najdrowski, 2005;Rezaei, 2010 andCraig et al, 2007). This may be due to some factors related to sex, such as pregnancy and lactation in females make ewes to be more susceptible to infection with coccidia (Heidari et al, 2014).…”

Ovine coccidiosis is an enteric protozoal disease caused by obligatory intracellular Eimeria spp. (Family: Eimeridae) and cause severe economic losses in sheep industry. The present studywas conducted in Menoof district, Menoufia, Egypt from January to December 2019 to determine the prevalence of sheep coccidiosis and to identify the recovered Eimeria spp. Faeces of 610 randomly selected sheep were collected directly from rectum and subjected to parasitological examination (floatation technique). The results revealed that Eimeria spp. were detected in 33.3 % (203 out of 610). The prevalence was significantly influenced by season, age and sex of the examined sheep. Six Eimeria species were identified: Eimeria parva 78 (38.4%), Eimeria ahasta 30 (14.8%), Eimeria granulosa 29 (14.3%), Eimeria pallida 43 (21.2%), Eimeria fauri 10 (4.9%) and Eimeria crandalis 13 (6.4%). This is the first report of ovine coccidiosis in Menoufia, Egypt. Further studies as molecular diagnosis is required to easily discriminate different Eimeria species infecting sheep.

“…Conversely, Sulaiman et al [32] observed that the highest infection rate was 58.3% in males and 37.11% in females, Idris et al [47] elucidated that male lambs were more susceptible (4.66%) to the infection than females (4.15%) and Dabasa et al [42] recorded a higher infection rate in males (31%) than females (10.4%). While Ali [40], Yakhchali and Rezaei [48], Gizachew et al [44], Lakew and Seyoum [49], Yonas and Goa [46] recorded that the sex of sheep had no significant effect on the prevalence of Eimeria spp. In the authors' opinion, the higher prevalence of coccidiosis in female sheep might be referred to the nature of immune status of females as well as the stress caused by pregnancy and lactation.…”

Background Coccidiosis is a potential protozoal disease of economic importance in sheep worldwide. The current study aimed to detect the prevalence of ovine coccidiosis and identification of the recovered species in Minya, Egypt. Three hundred and fifty sheep from Minia, Egypt, were coprologically examined for the occurrence of Eimeria species oocysts by using the standard floatation technique. Results Oocysts were detected in 180 (51.43%) animals. Mixed infection was recorded in 37.14% (130/350) and single infection was revealed in 14.29% (50/350) sheep. The prevalence of coccidiosis was significantly higher in young sheep. Fourteen Eimeria species were detected; Eimeria bakuensis, E. webybridgensis, E. ahusta, E. intricata, E. granulosa, E. faurei, E. ninakohlyakim-ovae, Eimeria coitae-like, E. parva, E. pallida, E. marsica, E. crandallis, E. ovinoidalis and E. arloingi. The most predominant Eimeria species was Eimeria parva (14.57%; 51/350) followed by E. ovinoidalis (14.0%; 49/350), E. granulosa (8.29%; 29/350), E. bakuensis (7.14%; 25/350), E. intricata (5.43%; 19/350), E. faurei and E. webybridgensis (4.86%; 17/350 each), E. pallida (4.0%; 14/350), E. ninakohlyakim-ovae (3.71%; 13/350), E. crandallis and E. ahsata (3.43%; 12/350 each), E. marsica and E. arloingi (1.71%; 6/350 each). The least abundant species was E. coitae-like (1.14%; 4/350). Conclusion Fourteen Eimeria species were recovered from sheep in Minya, Egypt; Eimeria bakuensis, E. webybridgensis, E. ahusta, E. intricata, E. granulosa, E. faurei, E. ninakohlyakim-ovae, Eimeria coitae-like, E. parva, E. pallida, E. marsica, E. crandallis, E. ovinoidalis and E. arloingi. Eimeria parva was the most common while E. coitae-like was the least. To the best of our knowledge, this is the first report for the occurrence of E. coitae-like in sheep in Egypt. Prevention and effective control programs should be strictly followed to avoid economic losses resulted from the coccidian infection.

“…On the other hand, this result disagreed with Sulaiman et al, (2005) who observed that the highest infection rate was in males (58.3%) than females (37.11%), Idris et al (2012) who observed that male lambs (4.66%) were more susceptible to infection than females (4.15%), and Dabasa et al, (2017) who recorded males more infected (31%) than females (10.4%). While Ali (2005) in Sudan, Nasr et al, (2008) in Sharkia, Yakhchali and Pezaei (2010), Gizachew et al (2014), Lakew and Seyoum (2016), Yonas and Goa (2017) recorded that the sex of sheep had no significant effect on prevalence of Eimeria. Higher incidence in females may be attributed to nature of immune status of females as well as stress caused by pregnancy and lactation.…”

Sheep coccidiosis is an infection of economic and medical importance and have been observed in almost all alive sheep rearing in the world. Examination of 928 sheep fecal samples from different localities in Kaloubia Governorate for detection of Eimeria infection revealed a prevalence rate of 72.5% (n= 673/928). The identified Eimeria species oocysts were Eimeria candelas (78.3%), E. granulosa (63%), E. ovinoidalis (41%), E. parva (31.5%), E. pallida (22.1%), E. intricata (6.8%), E. faurei (6.2%) and E. ahasta (4.9%). The prevalence rate was high in females (76.3%) as compared to males (68.3%). The incidence of infection peaked in winter (83.1%) followed by spring (80.8%), while the lowest rate was in summer (61.0%). High prevalence rate was recorded in ages > 6 months (90.8%), followed by 6-12months (73.6%), while the lowest rate was in sheep over 1 year of age (55.6%). Single infection was recorded in 26.6% of infected sheep. Double infection rate was in 29.7% while mixed infection rate was in 43.7%. With regard to breeds, Rahmany and Osemy breed showed the highest infection rate (80.9% and 73.9%; respectively). On the other hand, Baladi breed showed the lowest infection rate (58.3%). Immunized dam with UV attenuated Eimeria oocysts and their progeny showed a significant increase in both IgG and IgM as compared to non-immunized control group. Biochemical analysis Immunized dams and their progeny showed high level of albumin, Beta and Gamma concentration levels as compared to control dams and their progeny. Conclusion, it could be concluded that Egyptian sheep was infected by 8 species of Eimeria with predominant of Eimeria crandalis and Eimeria granulosa. New born lambs from immunized ewes have high serum immunoglobulin especially IgG compared to those from non-immunized ewes. Recommendation, Immunization of pregnant ewes by two doses UV irradiated Eimeria oocysts one month before parturition to give protection to their progeny.
