Background: The Protozoan pathogen Eimeria is a significant issue in poultry production. Scientists are concerned with finding alternative strategies due to the spread of resistance against the commonly employed coccidiostats. This study examined how well myrrh extract (MyE) protected domesticated pigeons from an experimental Eimeria labbeana-like infection.

In this study, we aimed to investigate the inhibitory mechanisms of β-glucuronidase by flavonoids derived from Alhagi graecorum through both experimental and computational approaches. The activity of β-glucuronidase was assessed using an in vitro enzyme inhibition assay, where myricetin and chrysoeriol were identified as potent inhibitors based on their low IC values. Kinetic studies were conducted to determine the inhibition type, revealing that both compounds exhibit noncompetitive inhibition of β-glucuronidase-catalyzed hydrolysis of PNPG.

Introduction: Coccidiosis is a serious parasitic disease in camels caused by an intestinal protozoan parasite of the genus , which is linked to significant causes of reduced milk and meat production. In Saudi Arabia, scare literature focused on the coprological investigation of dromedary camels (). To determine the taxonomic status of camel parasite species, we performed morphological characterization of oocysts and genetic analysis ( and gene regions) of species collected from camels in Riyadh, Saudi Arabia.

Introduction: Tobacco use is a major global health issue linked to psychiatric illnesses and high mortality rates. Nicotine, the primary compound absorbed during smoking, causes harm to various organs, particularly the brain. The current study examined the modulatory effect of Teucrium polium extract (TPE) on nicotine-induced biochemical and histological changes in the brains of mice.

Vanillin, a key flavor compound found in vanilla beans, is widely used in the food and pharmaceutical industries for its aromatic properties and potential therapeutic benefits. This study presents a comprehensive quantum chemical analysis to elucidate the interaction mechanisms of vanillin with CYP450 enzymes, with a focus on mechanism-based inactivation. Three potential inactivation pathways were evaluated: aldehyde deformylation, methoxy dealkylation, and acetal formation.

Article Synopsis
  • The study explores the anticoccidial properties of Olea europaea (olive tree) stem and leaf extracts against drug-resistant Eimeria spp., harmful parasites in poultry.
  • Gas chromatography-mass spectrometry analysis identified 12 phytochemical compounds in the leaf extract and 9 in the stem extract, with both being rich in beneficial chemicals like phenols and flavonoids.
  • In vitro tests showed that both extracts effectively inhibited the sporulation of Eimeria papillata oocysts at a high concentration (200 mg/ml), outperforming commercial products, suggesting their potential for further research as a cost-effective treatment.

Introduction: Recently, the use of botanicals as an alternative to coccidiostats has been an appealing approach for controlling coccidiosis. Therefore, this study was conducted to evaluate the potential role of aqueous methanolic extract (200 mg/kg) of (roots) (KLRE) against infection induced by .

Methods: A total of 25 male C57BL/6 mice were divided into five groups (I, II, III, IV, and V).

Coccidiosis is a protozoan parasitic disease caused by Eimeria species and affects wild and domestic animals. Coccidiostats are currently available to control this disease, although drug resistance has been confirmed for all of them. As a result, there is an urgent need to identify eco-friendly agents to control and treat this disease.

Article Synopsis
  • - Coccidiosis is a disease caused by protozoa that impacts poultry globally, and this study aimed to identify the specific Eimeria species affecting broiler chickens in Saudi Arabia using both morphological and molecular techniques.
  • - Researchers collected 25 fecal samples from chickens and found that 32% tested positive for coccidiosis, identifying the oocysts as Eimeria acervulina based on their size and shape characteristics.
  • - The study emphasized the effectiveness of molecular tools, alongside traditional morphological methods, for accurately identifying Eimeria species, which can help develop better strategies for controlling coccidiosis in poultry.

Coccidiosis is the most prevalent disease-causing widespread economic loss among farm and domestic animals. Currently, several drugs are available for the control of this disease but resistance has been confirmed for all of them. There is an urgent need, therefore, for the identification of new sources as alternative treatments to control coccidiosis.

Coccidiosis, caused by apicomplexan Eimeria species, is a protozoan disease that affects various species of wild and domestic animals. However, data available on Eimeria diversity in ruminants in Saudi Arabia is meagre. Therefore, this study was designed to investigate some eimerian parasites infecting sheep (Sawakni and Harrie breeds) using microscopy and molecular methods for the first time in Saudi Arabia.

Although several anticoccidial medications have long been used to prevent coccidiosis, their adverse effects necessitate the use of alternative control methods. In this study, was used to infect the mouse jejunum, and the response of the liver to induced coccidiosis on treatment with nanosilver synthesized from (NS) and the reference anticoccidial drug amprolium was compared. Mice were infected with 1000 sporulated oocysts to induce coccidiosis.
