Population genetic diversity and dynamics of the honey bee brood pathogen Melissococcus plutonius in a region with high ...

Published in Journal of invertebrate pathology

European foulbrood (EFB) is a honey bee brood disease caused by the bacterium Melissococcus plutonius. Large-scale EFB outbreaks have been reported in several countries in recent decades, which entail costly sanitation measures of affected apiaries to restrict the spread of this contagious pathogen. To mitigate its impact, a better understanding of...

Cordycepin, a metabolite of Cordyceps militaris, reduces immune-related gene expression in insects.

Published in Journal of invertebrate pathology

Hypocrealean entomopathogenic fungi (EPF) (Sordariomycetes, Ascomycota) are natural regulators of insect populations in terrestrial environments. Their obligately-killing life-cycle means that there is likely to be strong selection pressure for traits that allow them to evade the effects of the host immune system. In this study, we quantified the e...

Invertebrate RNA virus diversity from a taxonomic point of view.

Published in Journal of invertebrate pathology

Invertebrates are hosts to diverse RNA viruses that have all possible types of encapsidated genomes (positive, negative and ambisense single stranded RNA genomes, or a double stranded RNA genome). These viruses also differ markedly in virion morphology and genome structure. Invertebrate RNA viruses are present in three out of four currently recogni...

Budded baculovirus particle structure revisited

Published in Journal of Invertebrate Pathology

Baculoviruses are a group of enveloped, double-stranded DNA insect viruses with budded (BV) and occlusion-derived (ODV) virions produced during their infection cycle. BVs are commonly described as rod shaped particles with a high apical density of protein extensions (spikes) on the lipid envelope surface. However, due to the fragility of BVs the co...

Differential oxidative stress responses in castor semilooper, Achaea janata.

Published in Journal of Invertebrate Pathology

Balance between reactive oxygen species (ROS) and the antioxidant (AO) defense mechanisms is vital for organism survival. Insects serve as an ideal model to elucidate oxidative stress responses as they are prone to different kinds of stress during their life cycle. The present study demonstrates the modulation of AO enzyme gene expression in the in...

Reverse transcription loop-mediated isothermal amplification for rapid and quantitative assay of covert mortality nodavi...

Published in Journal of Invertebrate Pathology

A disease known as covert mortality disease has become an increasing problem in the shrimp farming industry in recent years in China and several countries of Southeast Asia, leading to serious losses in production. Litopenaeus vannamei (also known as Pacific white shrimp) is affected by this disease that leads to a range of clinical symptoms includ...
