Virulence Associated Morphology of Different Strains of Melissococcus plutonius, a Brood Pathogen of Honey Bees. [PDF]
Environ Microbiol RepThis study explores the diversity in cell morphology and growth behaviours of three Melissococcus plutonius strains, the causative agent of European foulbrood, employing electron microscopy and expression analysis of glycan‐binding protein candidate genes. Our results illustrate the mechanism of cell separation and the formation of individual cocci and

Wake Up and Smell the Infected Bees: Volatile Cues of <i>Vairimorpha</i> Infection in Honey Bees. [PDF]
Ecol EvolInfection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Epidemiological study for detection of the main and secondary agents of European foulbrood disease in the apiaries of Iran. [PDF]
Vet Res ForumInfecting to Melissococcus plutonius, the primary cause of the European foulbrood (EFB) disease, can be followed by infecting to the secondary bacteria, such as Enterococcus faecalis and Brevibacillus laterosporus. The aim of this research was to diagnose EFB disease by tracking the causes of the disease in apiaries all over Iran.
