“…Out of the nine found, the most common were the genera E. crandalis, E. ovina and E. ashata that were most prevalent with 22.85%, 18.30% and 21.42% respectively. This corresponds with the findings of (Adeyemi et al, 2021;Akerejola et al, 1979;El-Alfy et al, 2020;Hashemnia et al, 2012;Yakhchali & Golami, 2008).

Coccidiosis is a disease that destroys the intestinal mucosa which is caused by the protozoa parasites of the genus Eimera or Isospora species. The symptoms include diarrhoea, fever, weight loss, emaciation and consequently, death. Many infections are subclinical (that is, not severe enough to cause readily observable symptoms). Coccidiosis is an economically important disease of cattle, sheep, goats, pigs, poultry and also rabbits, in which the liver and intestine are affected. In dogs, cats, and horses, coccidiosis is less often diagnosed but can result in clinical illness.

“…However, it may persist in the herds without showing any clinical signs. The current study revealed that E. crandallis parasitized the nucleus of host intestinal epithelial cells and ultimately divides them by cell synchronization [ 10 ].…”

“…Eimeria crandallis ( E. crandallis ) is considered a pathogenic species associated with weight loss. With respect to animals under stress, such as during transit, aggregation in new feedlots, or the initiation of dietary changes, a clinical-stage may evolve quickly [ 10 ]. E. crandallis are considered the most pathogenic because they can grow in Lieberkühn-crypt cells [ 11 ].…”

Coccidiosis is a protozoan disease that is characterized by diffuse diarrhea, dehydration, emaciation accompanied by moderate morbidity and mild mortality in animals and birds. The current study targeted the molecular characterization of Eimeria isolates in captive deer from different localities in Lahore. The host species was the Cervidae family, such as Hog deer (Axis porcinus) and Punjab urial (Ovis aries vignei). The Eimeria crandallis was isolated from zoo animals. The DNA was extracted from oocysts and amplified by using reported oligonucleotide primers that exhibited the 809 bp product. These were analyzed by using the small subunit 18S rRNA gene-based evolutionary relationship with 36 other Eimeria species reported in caprine, cervinae, bovines, avians, and rodents. Light microscopic examination exhibited 3.29% (7/213) Eimeria-positive fecal samples with morphological features, including sub-spherical forms, the presence of micropyle with polar cap, and oocysts diameters (μm) ranging from 24.32 ± 1.61 to 18.94 ± 1.51. The phylogenetic tree constitutes four distinct clusters with relatively higher values. The evolutionary network showed that sequences were clustered in the monophyletic group of Eimeria species reported in caprine and cervinae. The nucleotide and amino acid sequence similarity matrix analysis exhibited 99.5–99.9% identity of the study isolates with Eimeria crandallis (AF336339). This study provides relevant baseline data to develop strategic control measures for coccidiosis in zoo animals. However, further investigations are required to place the hog deer and Punjab urial-derived E. crandallis into the caprine-originated cluster.

“…The most prevalent species in this study were E. ovinoidalis and E. crandallis. These species are commonly reported in sheep worldwide (Saratsis et al, 2011;Lopes et al, 2013;El-Alfy et al, 2020;Olmos et al, 2020;Al-Neama et al, 2021), and the predominance could be due to their higher reproductive efficiency compared to other species (Catchpole et al, 1976). Eimeria ovinoidalis and E. crandallis are pathogenic, and they are responsible for clinical coccidiosis, even in adult sheep (Olmos et al, 2020).…”

The present study aimed to perform an epidemiological and morphological identification of Eimeria infection in sheep in Brazil. Fecal samples from sheep were collected from 20 farms in northern Paraná, Brazil. An epidemiological questionnaire was used to evaluate the risk factors. Fecal samples containing oocysts per gram of feces (OoPG) ≥1000 were subjected to the modified Willis-Mollay method to perform oocyst identification. Sporulated oocysts were observed microscopically for morphological identification. A total of 807 fecal samples were collected. Based on the morphological characteristics of the sporulated oocysts, 10 species of Eimeria were identified, with main species observed: Eimeira ovinoidalis (98.1%), Eimeria crandallis (87.6%), Eimeria parva (79.1%), and Eimeria bakuensis (60.8%). Only 2.6% (7/268) of the sheep were infected with a single species, 4.8% (13/268) contained two different species, and 92.5% (248/268) were infected with three or more species. The analysis of risk factors showed that an intensive rearing, no rotation of pasture, dirt, and slatted floors, and age up to 12 months were associated with infection. This study showed a high prevalence of Eimeria natural infection in sheep from northern Paraná, Brazil. Furthermore, based on the risk factors, good management and hygiene practices must be employed to avoid infection.
