Using uniplex RT-PCR we screened honey bee colonies for the presence of several bee viruses, including black queen cell virus (BQCV), deformed wing virus (DWV), Kashmir bee virus (KBV), and sacbrood virus (SBV), and described the detection of mixed virus infections in bees from these colonies. We report for the first time that individual bees can harbor four viruses simultaneously. We also deve...

Background and Aim: Recently, viral diseases of honey bees (Apis mellifera) have presented an increasing threat to beekeeping. This study aimed examine the presence bee viruses in Apis non-Apis species, mite Varroa destructor, pollinated plants Armenia. Materials Methods: Sampling was performed Tavush Province, northeast Republic Armenia, from August November 2019. Overall, 200 A. mellifera bee...

Bee venom (BV) was used from long time ago in the medical field as treatment of chronic joint affections. In the recent decades, the screening process of new sources of antimicrobials discovers its high advantageous characteristics for combating various types of microbes, as well as trials to discover its anti-cancer medicinal fields. Lumpy skin disease virus (LSDV) causes disease in cattle of ...

Triatomine assassin bugs comprise hematophagous insect vectors of Trypanosoma cruzi , the causative agent Chagas disease. Although microbiome these species has been investigated to some extent, only one virus infecting Triatoma infestans identified date. Here, we describe for first time seven (+) single-strand RNA viruses (RpV1-7) Rhodnius prolixus a primary vector disease in Central and South ...

Viruses from the family Iflaviridae are insect pathogens. Many of them, including slow bee paralysis virus (SBPV), cause lethal diseases in honeybees and bumblebees, resulting in agricultural losses. Iflaviruses have nonenveloped icosahedral virions containing single-stranded RNA genomes. However, their genome release mechanism is unknown. Here, we show that low pH promotes SBPV genome release,...

Bee samples were collected in French apiaries that displayed severe losses and mortality during the winter (from November 2007 to March 2008). They were screened for the presence of Israeli acute paralysis virus (IAPV) by using RT-PCR. Five out of 35 surveyed apiaries, located in two different geographical areas, were found positive. This represents the first reported detection of IAPV in Franc...

We investigated pathogens in the parasitic honeybee mite Varroa destructor using nanoLC-MS/MS (TripleTOF) and 2D-E-MS/MS proteomics approaches supplemented with affinity-chromatography to concentrate trace target proteins. Peptides were detected from the currently uncharacterized Varroa destructor Macula-like virus (VdMLV), the deformed wing virus (DWV)-complex and the acute bee paralysis virus...
