Article
Full-text available
Strategies to control goat coccidiosis traditionally rely on the use of management practices combined with anticoccidial treatments, and limited effort has been made, so far, to address immunological control of caprine Eimeria infections. Previously, we showed that monospecific immunization with X-Rad-attenuated Eimeria ninakohlyakimovae oocysts in...
Article
Eimeria ninakohlyakimovae represents a highly pathogenic coccidian parasite causing severe haemorrhagic typhlocolitis in goat kids worldwide. NETosis was recently described as an efficient defense mechanism of polymorphonuclear neutrophils (PMN) acting against different parasites in vitro and in vivo. In vitro interactions of caprine PMN with paras...
Article
Continuous use of anticoccidial treatments against Eimeria infections has resulted in the development of drug resistance. This study aimed to evaluate the anticoccidial efficacy of a methanolic extract derived from the endemic Canary rue (Ruta pinnata) plant of the Canary Islands, Spain, against Eimeria ninakohlyakimovae using in vitro assays. Fres...
Article
Bituminaria bituminosa (C.H. Stirt.) is a drought tolerant legume that grows spontaneously in subtropical areas: Canary Islands (Spain) and in North African and Mediterranean regions, traditionally used as forage for ruminants. The aim of this research was to investigate the potential of B. bituminosa as a high protein resource for poultry feed by...
Article
Both the immune response developed in ruminants against Eimeria spp. and the ability to bear patent infections seems to be dependent on the age of the host. In the present study we have evaluated the influence of the age in the development of protective immune responses against Eimeria ninakohlyakimovae. For this purpose, 3, 4 and 5-week-old goat k...
Article
During the first schizogony, the goat coccidia Eimeria ninakohlyakimovae develops macroschizonts in lacteal duct endothelial cells, whose rupture leads to severe ileal damage and clinical signs during the prepatent period. The immune response elicited against early stages of the parasite development still requires to be investigated. In the present...
Article
Although cellular immune reactions seem to be crucial for protective immune responses in Eimeria spp. infections, there are also evidences on an active involvement of the humoral counterpart. In the present study, we have analyzed the humoral response of goat kids subjected to primary and challenge infections with Eimeria ninakholyakimovae. Specifi...
Article
Full-text available
Eimeria ninakohlyakimovae is an important coccidian parasite of goats which causes severe diarrhoea in young animals. Specific molecules that mediate E. ninakohlyakimovae host interactions and molecular mechanisms involved in the pathogenesis are still unknown. Although strong circumstantial evidence indicates that E. ninakohlyakimovae sporozoite i...
Article
The limitations associated with the use of anthelmintic drugs in the control of gastrotintestinal nematodosis, such as the emergence of anthelmintic resistance, have stimulated the study of the immunological control of many parasites. In the case of Haemonchus contortus, several vaccination trials using native and recombinant antigens have been con...
Article
Full-text available
Caprine coccidiosis, affecting mainly young goat kids around the weaning period, is worldwide the most important disease in the goat industry. Control of caprine coccidiosis is increasingly hampered by resistances developed against coccidiostatic drugs leading to an enhanced need for anticoccidial vaccines. In the current study we conducted an oral...
Article
Coccidiosis caused by the apicomplexan protozoa Eimeria ninakohlyakimovae has a high impact on animal health and profitability of the goat industry worldwide. Primary E. ninakohlyakimovae infections induce clinical disease mainly in goat kids, as homologous re-infections are commonly under immunological control. Nevertheless, there is evidence of f...
Article
Full-text available
The current study was conducted to isolate a field strain of Eimeria ninakohlyakimovae, characterize its infectivity and the response to challenge under experimental conditions. The isolated strain (GC) induced a prepatent period of 14-15days p.i., a patency of 7±2days and a noticeable pathogenicity in infected goat kids. Challenge trials resulting...
Article
Full-text available
Coccidiosis is probably the main parasitic disease affecting goat kids around the weaning period, leading to high economic losses in goat production due to deaths and delayed growth rates of infected animals. A total of 101 kids of 2-4 weeks of age, naturally infected with Eimeria spp., were divided into five groups and studies were conducted to an...
Article
Infections with Eimeria ninakohlyakimovae represent important coccidian diseases of goats severely affecting animal health and profitability of goat industry. For the development of suitable vaccination strategies basic research is needed for which one important prerequisite is the establishment of in vitro cultures guaranteeing the availability of...
Article
Radial immunodiffusion was used to determine immunoglobulin (Ig)-G concentrations in 16 mammary secretions from uninfected udder halves and in 10-14 secretions from halves subclinically infected with coagulase-negative staphylococci in goats throughout lactation. IgG concentrations in samples from uninfected halves decreased rapidly during the firs...

A 16-year-old, male, Hanoverian horse had a three-month history of weight loss, hirsutism and polyuria/polydypsia. Examinations revealed neutrophilia, lymphopenia, hyper glycaemia and abnormalities in hepatic function. A tentative diagnosis of hyperadrenocorticism was made. The results of thyroid-releasing hormone and combined dexamethasone suppres...
