Effect of Dietary Curcuma, Capsicum, and Lentinus, on Enhancing Local Immunity against Eimeria acervulina Infection

The Journal of Poultry Science, 2010
The protective effect of orally administered Curcuma longa (turmeric), Capsicum annuum and C. frutescens (hot pepper), and Lentinus edodes (shiitake mushroom) on avian coccidiosis was evaluated in young broilers.

Identification of protective peptides of Fasciola hepatica-derived cathepsin L1 (FhCL1) in vaccinated sheep by a linear B-cell epitope mapping approach

Parasites & Vectors, 2020
Background Fasciolosis is one of the most important parasitic diseases of livestock. The need for better control strategies gave rise to the identification of various vaccine candidates.

Expression of free radicals by peritoneal cells of sheep during the early stages of Fasciola hepatica infection

Parasites & Vectors, 2018
Background The majority of vaccination studies against infection with F. hepatica in a natural host have been conducted at the late stage of the infection when the host's immune response is already immunomodulated by the parasite towards a Th2 non ...

Direct-Fed Microbials and Their Impact on the Intestinal Microflora and Immune System of Chickens

The Journal of Poultry Science, 2010
Direct-fed microbials (DFMs) are live microorganisms which confer a health benefit to the host. The mode of action of DFMs involves multiple mechanisms, including direct inhibition of enteric pathogens and indirectly through competitive exclusion of ...

Efficacy of a multivalent vaccine against Fasciola hepatica infection in sheep

Veterinary Research, 2021
In this work we report the protection found in a vaccination trial performed in sheep with two different vaccines composed each one by a cocktail of antigens (rCL1, rPrx, rHDM and rLAP) formulated in two different adjuvants (Montanide ISA 61 VG (G1) and ...

Intrinsic Factors Influencing the Infection by Helminth Parasites in Horses under an Oceanic Climate Area (NW Spain)

Journal of Parasitology Research, 2009
A coprological survey to determine the influence of some intrinsic factors (breed, age, and sex) on the infection by helminth parasites in equine livestock (n=418) under an oceanic climate area (NW Spain) was conducted.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
