“…In the present study, some lambs grazed with adults in a communal grazing system, which exposed them to mild infection. In the studies conducted by Maingi and Munyua (1994), Craig et al (2006), andHashemnia et al (2014), nematode and coccidial infections of lambs were reported, which was consistent with the results of the current study. They explained that male sheep were prone to gastrointestinal helminths because of the production of androgen hormones, which seem to suppress the immune response of the male sheep.…”

The present study aimed to evaluate the effect of the agroecological zone, host age, and gender on the prevalence and faecal egg load of gastrointestinal parasites (GIPs) for six months (July to December) in the Maseru and Quthing districts, Lesotho. A total of 1919 faecal samples were examined using the McMaster technique. The data were analyzed through generalized estimating equations (GEE) under the binary logistic regression model to determine the significant differences for the GIPs prevalence. Moreover, faecal egg counts (FEC) data were analyzed for repeated measures using GEE. In total, three types of GIPs, namely nematodes, coccidia, and cestodes were identified in this study. The overall prevalence rates of nematodes, coccidia, and cestodes were 53.9%, 46.5%, and 4.3% in the Maseru district, respectively. Furthermore, the Quthing district indicated the prevalence rates of 65.0%, 38.2%, and 0.9% for nematodes, coccidia, and cestodes, respectively. In the Maseru district, the overall faecal egg counts for nematodes, coccidia, and cestodes were within the ranges of 0-20.3, 0-90, and 0-600 eggs per gram, respectively. Additionally, the faecal egg counts in the Quthing district ranged from 0 to 8.000, 6.700, and 2.000 eggs per gram for nematodes, coccidia, and cestodes, respectively. The majority of the Merino sheep (>69%) in both districts had lower faecal egg counts (100-800) per gram. The agroecological zone affected the nematode infestation in both districts. Coccidia in the Quthing was higher in the mountain areas. In the Maseru district, the nematode infestation was not age-dependent; however, in the Quthing district, the prevalence was higher in juveniles, compared to adults. Age and gender did not affect the prevalence and faecal egg counts of nematodes and coccidia. The coccidian faecal egg loads were higher in females, compared to males. Merino sheep in Lesotho are mostly infected with gastrointestinal nematodes and protozoal coccidia, which could have a tremendous impact on their health and productivity. It is, therefore, of significant importance to develop the deworming strategy for sheep of different age and gender groups in different agroecological zones.

“…Molecularly the results recorded five different species of Eimeria in sheep that which E. ahsata 33.33% E. weybridgensis 22.22%, E. ovinoidalis 16.66%, E. bovis 16.66% and E. auburnensis 11.11%, where the first three species are a specific for sheep, while the two later a specific for cattle. These results are agreed with the result of Platzer et al (21) who recorded three species included E. ovinoidalis, E. weybridgensis and E. ahsata in Austria, Hashemni et al (22) who recorded E. ahsata in Western Iran and Kara (23) who confirmed E. ovinoidalis in Turkey.…”

Sheep eimriosis is one of the most important and common disease which infects sheep in all ages but it is more effective in lambs. The diarrhea with or without blood is the main signs of infection. Eimeria protozoan required single host to complete its life cycle which pass in different stages including schizogony, gametogony and sporogony. The study was designed for detection of sheep Eimeria species through the molecular method. This study was conducted in Al-Diwanyah province during the winter months of 2019. In which 200 sheep fecal samples were collected and examined traditionally to investigate the Eimeria oocytsts. Ninety-seven samples of highly intensity infection with Eimeria oocysts were selected to subject for DNA extraction process. The extracted DNAs were tested through amplification of internal transcribed spacer 1 (ITS-1) gene by conventional PCR, and then phylogenetic analysis was made to diagnose the sheep Eimeria species. All samples that examined microscopically were showed positive results of infections with Eimeria protozoan. Out of 97 molecularly examined samples, forty-five (46.39%) were given positive result in conventional PCR technique, where Eimeria spp. detected through succeeded amplification of internal transcribed spacer 1 (ITS-1) gene. Then phylogenetic analysis referred to that there are five species of Eimeria confirmed in sheep in Al-Diwanyah province including 6 (33.33%) samples diagnosed as E. ahsata, 4 (22.22%) samples E. weybridgensis, 3 (16.66%) samples E. ovinoidalis, 3 (16.66%) samples E. bovis and 2 (11.11%) samples E. auburnensis. So, the Eimeria protozoan appears as an endemic parasite and can infect sheep with different species in study area. The sheep can infect with both specific and nonspecific species.

“…Also, disconformity with the findings from [21] which reported prevalence rate 67.5% of coccidia in sheep in the province of AL-Muthanna but in Garmiyan Province, Kurdistan region recorded a low ratio of coccidiosis in sheep about 31.30% [22] all these reports recorded in Iraq, as well as in sheep of other countries. In Iran, the rate of Eimeria in sheep was 240 positive, the total rate of coccidiosis in sheep was 19.2% [23] . And in the Colombian Northeastern Mountain [24] which recorded prevalence of Eimeria spp.…”

Coccidiosis is a parasitic disease caused by the Eimeria spp. that affects sheep and ruminants and leads to important economic losses. Studying of incidence of coccidiosis will help us to decrease the coccidiosis infection in the sheep flocks, and resulting in novel control programs. The Eimeria prevalence in sheep is taken in the Diwaniyah city from March 2017 to February 2018. 200 sheep were used in this study ( 95Lambs and 105 Adult) that tested clinically by taking fecal samples and examined by a routine microscopic examination and conventional PCR. Results revealed that 57.5% of sheep were infected by the Eimeria parasite. Adult female sheep were more infected 77.9% than adult male sheep 41.3%, but in Lambs the parasite was higher in males 62% than the male 44.4%, also the overall prevalence of Eimeria spp. according to age was higher in adult's 60.9% than that in Lambs 53.6%. In conclusion, gender significantly affected the prevalence and severity of the infection. Age, possibly, might be a significant factor adding to the notable losses in sheep in the Diwaniyah city in Iraq.
