The reliable production of marine fish larvae is one of the major bottlenecks in aquaculture due to high mortalities mainly caused by infectious diseases. To evaluate if the compound poly-beta-hydroxybutyrate (PHB) might be a suitable immunoprophylactic measure in fish larviculture, its capacity to improve immunity and performance in European sea bass (Dicentrarchus labrax) yolk-sac larvae was explored. PHB was applied from mouth opening onwards ...

Viruses and plasmids (invasive mobile genetic elements (iMGEs)) have important roles in shaping microbial communities, but their dynamic interactions with CRISPR-based immunity remain unresolved. We analysed generation-resolved iMGE-host dynamics spanning one and a half years in a microbial consortium from a biological wastewater treatment plant using integrated meta-omics. We identified 31 bacterial metagenome-assembled genomes encoding ...

The spatial distribution of PRRSV-1 subtypes in Europe is quite stable, most probably due to a strong population immunity induced by the local PRRSV strains. In this study, we evaluated the potential of the immunity induced by several West European subtype 1 PRRSV strains (2007 isolate 07V063 and 2013 isolates 13V091 and 13V117) to provide a protection against the highly virulent East European subtype 3 PRRSV strain Lena. Eleven-week-old pigs ...

The immune system is one of the most important adaptations that has evolved to protect animals from a wide range of pathogens they encounter from early life onwards. During the early developmental period this is particularly true for the innate immunity, as other components of the immune system are, as yet, poorly developed. But innate immunity may not only be crucial for early life survival, but may also have long-lasting effects, for example ...

Varicella-zoster virus (VZV) is the causative agent of both varicella (chickenpox) and herpes zoster (HZ) (shingles). After varicella infection, the virus remains dormant in the hosts dorsal ganglia and can reactivate due to waning cell-mediated immunity, causing HZ. Exposure of varicella-immune persons to VZV may boost the hosts immune response, resulting in a protective effect against HZ. In this study, we used mathematical models of VZV ...

This Special Issue of The FEBS Journal consists of 20 reviews covering various aspects and new developments in 'Infection and Immunity'. The issue includes expert views on the role of different immune cell populations, on the regulation of innate and adaptive immune responses, and novel concepts in host defence and inflammatory signalling. Many reviews in this issue also highlight potential targets for future therapeutic interventions that aim ...

One of the strategies to maintain optimal gut health in animal production in the absence of antibiotic growth promoters is to support the active immunity of the animal. Immunity at the level of the digestive system is concentrated in the mucosal immune system of the gut associated lymphoid tissue (GALT). Therefore, the GALT is the obvious target if we want to increase intestinal immunity. M cells and dendritic cells sample the intestinal ...

The concept of Sweet Immunity postulates that sugar metabolism and signaling influence plant immune networks. In this study, we tested the potential of commercially available inulin-type fructans to limit disease symptoms caused by Botrytis cinerea in lettuce. Spraying mature lettuce leaves, with inulin-type fructans derived from burdock or chicory was as effective in reducing grey mold disease symptoms caused by Botrytis cinerea as spraying ...
