“…Our results are in agreement with those of previous investigations, showing the efficacy of plant extracts against mixed or individual Eimeria infections, which can be used as potential anticoccidials in broiler chickens [ 60 ]. In addition, another study suggested the use of a combination of plant extract multi-compounds induces a good response, as an immunostimulatory effect, to destroy the oocyst of Eimeria or interfere with their life cycle [ 61 ]. It has also been reported in the literature that phenolic components demonstrate a wide range of biological properties, such as antibacterial, anticancer, antiproliferative, and anti-inflammatory properties [ 62 , 63 , 64 ].…”

The objective of the present study is to identify the biochemical compounds extracted from OFI flowers using ultra-high-performance liquid chromatography–electrospray ionization quadrupole time-of-flight mass spectrometry and to evaluate their in vitro antioxidant activities and anticoccidial effects on the destruction of Eimeria oocysts isolated from naturally infected chickens. A domestic microwave was used with a refrigerant to condense the vapors generated during the extraction. The flavonoid and phenolic compound contents of the OFI flowers were determined according to standard methods. DPPH radical and H2O2 scavenging capacities were used to assess the antioxidant activity. Regarding the anticoccidial activity, the Eimeria spp. oocysts used were isolated from the fresh feces of infected broilers and were determined in triplicate by incubation at an ambient temperature for 24 h. The results highlighted the considerable influence of the optimized acetone concentration, ratio, irradiation time, and microwave power parameters on the phenolic content and antioxidant activities. Our results revealed significant matches between the predicted and experimental values of the models. Molecular analysis revealed the presence of several biophenol classes such as quercetin, isorhamnetin 3-O-rutinoside, and quercetin-3-O-rutinoside. OFI flower extracts inhibited sporulation and damaged the morphology of Eimeria oocysts compared with normal sporulated Eimeria oocysts containing sporocysts. In conclusion, the optimized conditions were validated and found to fit very well with the experimental values. These findings suggest that the flowers of OFI should be considered sources of antioxidants. The results of the present study revealed that OFI flower extracts have anticoccidial activities against Eimeria-spp.-induced infection in broiler chickens.

“…A lot of natural herbs and their extracts were also practiced against coccidiosis like Trachyspermum ammi (Ajwain) by Abbas et al [13] but they have no significance as compared to chemotherapy. These compounds can act a little against some Eimeria species but not all due to huge genetic variability, which degrades their effect [14,15].…”

Coccidiosis is a fatal disease of poultry, caused by Eimeria species and considered the most prominent and destructive disease within all protozoal diseases. Chemotherapy is considered the main preventive strategy against coccidiosis. Chemotherapy is partially successful and has many drawbacks as it is practiced after the outbreak of disease, until then coccidiosis causes huge production and health losses. As an alternative, prophylactic measures like vaccination and management betterment are of eminent importance and can help to overcome this disease. Vaccination can induce antibody-mediated immunity, cell-mediated immunity or both. However, ordinary vaccines do not offer enough potential to overcome Eimeria species at its full extent. Different research trials and studies have shown that DNA vaccines can induce both antibody and cell-mediated immunity. Several DNA vaccines have been tested in the last few years with marvelous results but still no vaccine is available commercially. Here we will discuss different types of vaccines against Eimeria, especially in poultry. A comparative analysis along with the recent advancements will reveal the types of vaccines that bear sufficient potential to overcome Eimeria species to its full extent. This review will also describe the fruitful and advanced steps towards the synthesis of molecular vaccines in the future.

“…Eimeria tenella is one of the most pathogenic protozoan parasites of the genus Eimeria, causing chicken coccidiosis worldwide (Quiroz-Castañeda, 2018). E. tenella infection is known to occur in the medial and distal parts of the chicken's cecum (Matsubayashi et al, 2012).…”

This study was conducted to evaluate the effects of four dosages of oocyst inoculation (1×102, 1×103, 1×104, and 1×105 oocysts/chick) on oocyst patterns in feces, lesion score, and the endogenous phase of Eimeria tenella in the tissue of infected chickens. Oocysts in feces were collected daily from 4 to 10 day-post-infection (dpi). Chickens were killed at 0, 3, 5, and 10 dpi to evaluate the lesion score and the endogenous phage in the tissue by hematoxylin and eosin staining. The results showed that chickens in the highest dosage group discharged oocysts the earliest (5 dpi), while oocysts were detected in the other 3 groups 1 day later (6 dpi). The results of the histopathological examination showed that the time to detect the development stages of E. tenella in the tissue was similar among the experimental groups. Specifically, the asexual stages (1st and 2nd schizonts) were detected at 3 dpi, and immature oocysts were found in the cecum tissue at 5 dpi in all experimental groups. Overall, the results indicated that the oocyst dosages do not affect the replication of E. tenella in intestinal epithelial cells but may influence the excretion of oocysts from the intestinal tissue.
