The aim of this study was to identify antigens for a vaccine or drug target to control rabbit coccidiosis. A combination of 2-dimensional electrophoresis, immunoblotting, and mass spectrometric analysis were used to identify novel antigens from the sporozoites of Eimeria stiedae. Protein spots were
The invasion and replication of Eimeria tenella in the chicken intestine is responsible for avian coccidiosis, a disease that has major economic impacts on poultry industries worldwide. E. tenella is transmitted to naïve animals via shed unsporulated oocysts that need contact with air and humidity
Coccidiosis induced necrotic lesions impair digestive capacity and barrier function in concurrence with increased risks for secondary bacterial infections. The industry has been successful in controlling coccidiosis with anticoccidials and vaccination. However, concerns over Eimeria species
The Cathepsin-D proteinase was demonstrated immunohistochemically in cases of intestinal coccidiosis in chickens; its expression concerned almost the cyto-invasive stages of reproductive cycle of several strains of coccidia (merozoites of the II-nd generation and also microgametes). The authors
Chicken coccidiosis, a disease caused by seven species of Eimeria (Apicomplexa: Coccidia), inflicts severe economic losses on the poultry industry. Eimeria tenella is the one of the most virulent species pathogenic to chickens. Many parasitic protozoans are parasitised by double-stranded (ds) RNA
BACKGROUND
Coccidiosis caused by protozoans of genus Eimeria is a chicken parasitic disease of great economical importance. Conventional disease control strategies depend on vaccination and prophylactic use of anticoccidial drugs. Alternative solution to prevent and treat coccidiosis could be
Apical membrane antigen 1 (AMA1) is a receptor protein on the surface of Toxoplasma gondii that plays a critical role in host cell invasion. The ligand to which T gondii AMA1 (TgAMA1) binds, TgRON2, is secreted into the host cell membrane by the parasite during the early stages of invasion. The
BACKGROUND
The protozoan Eimeria tenella is a common parasite of chickens, causing avian coccidiosis, a disease of on-going concern to agricultural industries. The high prevalence of E. tenella can be attributed to the resilient oocyst stage, which is transmitted between hosts in the environment. As
Motion is an intrinsic property of all living organisms, and each cell displays a variety of shapes and modes of locomotion. How structural proteins support cellular movement and how cytoskeletal dynamics and motor proteins are harnessed to generate order and movement are among the fundamental and
Avian coccidiosis, caused by Eimeria spp., is one of the major parasitic diseases in birds. Cysteine protease is a major virulence factor in parasitic protozoa, and it may be a suitable chemotherapeutic target and vaccine candidate molecule. A 100 amino acid (aa.) partial sequence of cathepsin L,
Rhoptries are specialized secretory organelles that are uniquely present within protozoan parasites of the phylum Apicomplexa. These obligate intracellular parasites comprise some of the most important parasites of humans and animals, including the causative agents of malaria (Plasmodium spp.) and
Chicken coccidiosis is caused by Eimeria spp., particularly Eimeria tenella, and is characterized by watery or hemorrhagic diarrhea, resulting in death in severe cases. Precociously attenuated live vaccines are widely used to control the disease, and these are produced by serially passaging virulent
