RESUMEN
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. In March, a higher abundance of AmFV-originated reads was identified in samples collected from warmer areas compared to those collected from cooler areas. A lower proportion of AmFV-derived reads were identified in samples collected in March from the wetter areas than those collected from the drier areas. AmFV-read abundance in samples collected in May showed no significant differences between groups based on either environmental temperature or precipitation. The AmFV abundance correlated negatively with Bartonella apihabitans, Bartonella choladocola, and positively with Frischella perrara, Gilliamella apicola, Gilliamella sp. ESL0443, Lactobacillus apis, Lactobacillus kullabergensis, Lactobacillus sp. IBH004. De novo metagenome assembly of four samples resulted in almost the complete AmFV genome. According to phylogenetic analysis based on DNA polymerase, the Hungarian strains are closest to the strain CH-05 isolated in Switzerland.

Os autores relatam as recentes informaçöes sobre o ciclo alternativo dos mixosporeos (Myxozoa) comprovados nos últimos anos nos oligoquetas, estimulando pesquisas para estudar o desenvolvimento das numerosas espécies de parasitas de peixes conhecidos e desconhecidos dos mixosporeos no Brasil. Ao mesmo tempo, formas de actinosporeos, raabeia, eliminados pelos oligoquetas da família Ocnerodrilidae, foram relatadas pela primeira vez no Brasil
