Introduction Anisakis simplex sensu stricto (s. s.) is one of the most widespread parasitic nematodes marine organisms, with humans as accidental hosts. While many studies have explored nematode biology and host interactions, role extracellular vesicles (EVs) signaling molecules in less understood. Materials methods Therefore, proteins present EVs A. (Anis-EVs) were identified. In addition, a cross-talk proteomic approach was used to identify differentially regulated (DRPs) proteome human...

Anisakis simplex L3 larvae infect fish and other seafood species such as squids or octopuses; therefore, humans consuming raw undercooked may become accidental hosts for this parasite. These are induced to enter hypometabolism by cold temperature. It is assumed that sugars (in particular trehalose glycogen) instrumental survival under environmental stress conditions. To elucidate the mechanisms of response in A. simplex, we observed effects starvation temperature on glycogen content,...

The activity of glycogen phosphorylase and carbohydrate hydrolyzing enzymes α-amylase, glucoamylase, trehalase, sucrase was studied in the development Carniolan honey bee, Apis mellifera carnica Pollman (Hymenoptera: Apidae), from newly hatched larva to freshly emerged imago worker drone. Phosphorolytic degradation significantly stronger than hydrolytic all developmental stages. Developmental profiles hydrolase were similar both sexes brood; high found unsealed larvae, lowest prepupae...

Abstract The pathogenesis of varroasis has not been fully explained despite intensive research. Earlier studies suggested that parasitic infections caused by Varroa destructor mites were accompanied immunosuppression in the host organism. objective this study was to analyse influence on one immune pathway Apis mellifera measured expression prophenoloxidase (proPO) gene and enzymatic activity gene’s product, phenoloxidase (EC 1.14.18.1). An evaluation done five developmental stages honey bee...

Trehalose and glycogen metabolism plays an important role in supporting life processes many nematodes, including Anisakis simplex. Nematodes, cosmopolitan helminths parasitizing sea mammals humans, cause a disease known as anisakiasis. The aim of this study was to investigate the expression genes encoding enzymes involved trehalose glycogen-trehalose-6-phosphate synthase (TPS), trehalose-6-phosphate phosphatase (TPP), (GS), phosphorylase (GP)-in stage L3 L4 larvae A. mRNA all four genes,...

Introduction: Anisakis simplex are parasitic nematodes that cause anisakiasis. The possibility of infection with this parasite is through consumption raw or undercooked fish products. A. infections often misdiagnosed, especially in subclinical cases do not present typical symptoms such as urticaria, angioedema, and gastrointestinal allergy. resulting allergic reactions range from rapid-onset potentially fatal anaphylactic to chronic, debilitating conditions. While there have been numerous...

Anisakis simplex s. is a parasitic nematode of marine mammals and causative agent anisakiasis in humans. The cuticle intestine the larvae are tissues most responsible for direct indirect contact, respectively, parasite with host. At L4 larval stage, tissues, such as intestine, fully developed functional, contrast to L3 stage. As such, this work provides first time tissue-specific proteome A. Statistical analysis (FC ≥ 2; p-value ≤ 0.01) showed that 107 proteins were differentially regulated...
