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 ...

A Clinical and Epidemiological Investigation of the First Reported Human Infection With the Zoonotic Parasite Trypanosoma evansi in Southeast Asia [PDF]

, 2016
Background. Trypanosoma is a genus of unicellular parasitic flagellate protozoa. Trypanosoma brucei species and Trypanosoma cruzi are the major agents of human trypanosomiasis; other Trypanosoma species can cause human disease, but are rare.

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.

Time-dependent RNA transcriptional profiling of abomasal mucosa in cattle infected with Ostertagia ostertagi

Scientific Data
In this study, we infected Holstein calves with Ostertagia ostertagi stage 3 larvae (L3) and determined gene expression profiles of abomasal fundic and pyloric mucosa by RNA sequencing (RNA-seq) at 3–5, 7–9, 10, and 21 days post-infection (dpi), which ...
