Apis mellifera filamentous virus from a honey bee gut microbiome survey in Hungary.

In Hungary, as part of a nationwide, climatically balanced survey for a next-generation sequencing-based study of the honey bee (Apis mellifera) gut microbiome, repeated sampling was carried out during the honey production season (March and May 2019). Among other findings, the presence of Apis mellifera filamentous virus (AmFV) was detected in all samples, some at very high levels. AmFV-derived reads were more abundant in the March samples than in the May samples.

Natural diversity of the honey bee (Apis mellifera) gut bacteriome in various climatic and seasonal states.

As pollinators and producers of numerous human-consumed products, honey bees have great ecological, economic and health importance. The composition of their bacteriota, for which the available knowledge is limited, is essential for their body's functioning. Based on our survey, we performed a metagenomic analysis of samples collected by repeated sampling.

Permanent prevalence of Nosema ceranae in honey bees (Apis mellifera) in Hungary.

Nosema ceranae is present in honey bee (Apis mellifera L.) colonies worldwide. Studies on the comparative virulence of N.

First detection and dominance of Nosema ceranae in Hungarian honeybee colonies.

Microsporidiosis (nosema disease) of the European honeybee ( Apis mellifera L.) is present in bee colonies worldwide. Until recently, Nosema apis had been regarded as the causative agent of the disease, which may have many negative effects on the colony and cause heavy economic losses in apicultures.

Detection of Pseudomonas aeruginosa in water samples using a novel synthetic medium and impedimetric technology.

Aims: To investigate whether the use of a novel synthetic medium in conjunction with impedimetric technology could provide a rapid and automated detection of Pseudomonas aeruginosa in water samples.

Methods And Results: A selective synthetic medium (Z-broth) in which the only carbon and nitrogen source is acetamide was applied in direct impedimetric examination for the selective isolation of P. aeruginosa.
