Abstract

Strains of members of the genus Corynebacterium derived from ophthalmologic patients in Japan, Belgium and Switzerland and found to be closely related to-, but distinguishable from Corynebacterium mastitidis by 16S rRNA gene sequencing, were characterized using biochemical, chemotaxonomic, MALDI-TOF mass spectrometry and antimicrobial susceptibility methods and DNA-DNA hybridization as well as by whole-genome sequencing (WGS). Based on this investigation, we describe Corynebacterium lowii sp. nov. and Corynebacterium oculi sp. nov., derived from human ocular specimens, as well as emend the description of Corynebacterium mastitidis. Type strains for these species are: C. lowii R-50085(T) (=LMG 28276(T) =CCUG65815(T)) and C. oculi R-50187(T) (=LMG 28277(T) =CCUG65816(T)). DNA G+C content was found to be 62.2%(by HPLC) and 62.8%(by WGS) for C. lowii R-50085(T), 64.1%(HPLC) and 64.8%(WGS) for C. oculi R-50187(T) and 67.8%(HPLC) for C. mastitidis LMG 19040(T) [=S-8(T) =CCUG38654(T) =CECT 4843(T) =CIP 105509(T) =DSM44356(T) =IFO (NBRC) 16160(T) =JCM 12269(T)].

Convivina is a specialised core gut symbiont of the invasive hornet Vespa velutina

Amanda Hettiarachchi, Margo Cnockaert, Marie Joossens, David Laureys, Jessika De Clippeleer, Nicolas J. Vereecken, Denis Michez, Guy Smagghe, Dirk C. de Graaf, Peter Vandamme

Summary: This study analyzed the cultivable bacterial communities of different compartments in the invasive insect Vespa velutina, as well as the nest samples, using both cultivation and 16S rRNA amplicon sequencing. The bacterial symbionts in Vespa velutina were dominated by Convivina, Fructobacillus, Lactiplantibacillus, Lactococcus, Sphingomonas, and Spiroplasma. Lactococcus lactis and Lactiplantibacillus plantarum were generalist core lactic acid bacteria (LAB) symbionts, while Convivina species and Fructobacillus fructosus were highly specialized core LAB symbionts with reduced genome sizes. Sphingomonas and Spiroplasma were non-LAB core symbionts, but they were not isolated. Convivina bacteria were particularly enriched in the hornet crop and included Convivina intestini, a species adapted to amino acid metabolism, and Convivina praedatoris sp. nov., which was adapted to carbohydrate metabolism.

A phylogenomic and comparative genomic analysis of Commensalibacter, a versatile insect symbiont

Juliana Botero, Atena Sadat Sombolestani, Margo Cnockaert, Charlotte Peeters, Wim Borremans, Luc De Vuyst, Nicolas J. Vereecken, Denis Michez, Guy Smagghe, German Bonilla-Rosso, Philipp Engel, Peter Vandamme

Summary: This study provides insights into the diversity and function of Commensalibacter bacteria in various insect species. Through analysis of their whole-genome sequences, it was found that Commensalibacter strains can be classified into four species, which share similar genetic pathways for central metabolism. However, there are differences in genome size, G+C content, amino acid metabolism, and carbohydrate-utilizing enzymes among these species. Notably, the study on the Western honey bee symbiont, C. melissae, revealed its unique characteristics such as reduced genome size and a large number of species-specific gene clusters.

Potential for climate change driven spatial mismatches between apple crops and their wild bee pollinators at a continental scale

Leon Marshall, Nicolas Leclercq, Timothy Weekers, Insafe El Abdouni, Luisa G. Carvalheiro, Michael Kuhlmann, Denis Michez, Pierre Rasmont, Stuart P. M. Roberts, Guy Smagghe, Peter Vandamme, Thomas Wood, Nicolas J. Vereecken

Summary: Visitation by wild bee species is essential for apple production, but they are vulnerable to climate change. We modeled the distribution range shifts of key apple-pollinating bee species under different climate change scenarios and found that overall contractions in range are limited. However, under the worst-case scenario, some countries such as France and Italy may experience significant loss in bee populations and potential pollination services. Climate change is not the only threat to apple pollination, and future deficits will also depend on orchard management and ecological infrastructure.
