7 results about "Eimeria" patented technology

Eimeria is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry, and smaller ruminants including sheep and goats. Eimeria species are considered to be monoxenous because the life cycle is completed within a single host, and stenoxenous because they tend to be host specific, although a number of exceptions have been identified. Species of this genus infect a wide variety of hosts. Thirty-one species are known to occur in bats (Chiroptera), two in turtles, and 130 named species infect fish. Two species (E. phocae and E. weddelli) infect seals. Five species infect llamas and alpacas: E. alpacae, E. ivitaensis, E. lamae, E. macusaniensis, and E. punonensis. A number of species infect rodents, including E. couesii, E. kinsellai, E. palustris, E. ojastii and E. oryzomysi. Others infect poultry (E. necatrix and E. tenella), rabbits (E. stiedae) and cattle (E. bovis, E. ellipsoidalis, and E. zuernii). For full species list, see below.

Phytogenic additive and application thereof in promoting growth and combating coccidiosis and / or necrotic enteritis

PCT designated stageWO2026117596A1Digestive systemAnimal feeding stuffProtozoaDisease
The present disclosure provides a method of reducing, preventing or treating an intestinal infection, preventing or treating a disease associated with protozoan parasite of the genus Eimeria, inhibiting an oocyst sporulation of a protozoan parasite or preventing a sporozoite invasion or reproduction, preventing or treating coccidiosis, promoting growth performance, controlling, treating and / or preventing necrotic enteritis in a subject, comprising administering to the subject an effective amount of a composition comprising a Crassocephalum rabens (CR), a bioactive extract thereof (CRE), an active ingredient(s) contained in a CR (CR_API) or CRE (CRE_API), a combination of two or more of a CR, a CRE, a CR_API and a CRE_API, or one or more of a-linolenic acid, citric acid, lactic acid, mannitol, palmitic acid, aspartic acid and 1-monomyristin.

A nanobody specifically binding eimeria subspores and uses thereof

The application belongs to the technical field of biotechnology and veterinary medicine, and particularly relates to a nano-antibody specifically combined with Eimeria stiedai sporozoite and application thereof. The nano-antibody comprises an amino acid sequence shown in SEQ ID NO:1. Experiments show that the nano-antibody can be efficiently combined with Eimeria stiedai sporozoite, and significantly inhibit invasion of the sporozoite into rabbit intrahepatic bile duct epithelial cells. The nano-antibody provides a new type of efficient biological preparation candidate for preventing and controlling rabbit Eimeria stiedai disease, and has important diagnostic application value.

Kit for the discovery and application of lyso-phosphatidylcholine (lpc) with anticoccidial effect

ActiveCN120847277BCurative effectEimeria
The application provides a lysophosphatidylcholine (LPC) kit with anti-coccidiosis effect, and discloses a diagnosis marker for Eimeria tenella infected chicken, which is characteristic phospholipid and sphingolipid molecules, and specifically phosphatidylcholine (PC), lysophosphatidylcholine (LPC) and sphingomyelin (SM). Meanwhile, the application provides a medicine composition for improving the survival rate of chicks infected with Eimeria tenella, which is characterized by containing effective amounts of 18:2 LPA, 18:1 LPC, 22:0 LPC, 16:0 18:1 PC, 16:0 18:2 PC and d18:1 16:0 SM. The application screens characteristic phospholipid and sphingolipid molecules in the cecum tissue of chicken infected with Eimeria tenella for the first time, and verifies the curative effect of phosphatidylcholine (PC), lysophosphatidylcholine (LPC) and sphingomyelin (SM) on acute infection of chicks with Eimeria tenella, which has great market development prospect.

Method for improving gene editing efficiency of eimeria tenella, tool and application thereof

PendingCN122128340AProtozoaMicroorganism based processesExogenous DNAEimeria
This invention provides a method, tool, and application for improving the gene editing efficiency of *Eimeria tenella*. The *Eimeria tenella* strain with KU80 deletion is obtained by knocking out the KU80 gene in *Eimeria tenella* using a CRISPR-Cas9 gene editing system. Compared with existing technologies, the tool and method of this invention can significantly improve gene-targeted integration efficiency, significantly reduce random integration events of exogenous DNA, and improve the accuracy and stability of gene editing. It is a universal gene editing platform that can be widely applied to gene knockout, gene knock-in, and endogenous marker research. The strain using this tool can significantly shorten the screening cycle for positive recombinant strains, improve experimental reproducibility, and provide important technical support for functional genomics research on *Eimeria tenella*.
