Integrated bacterial transcriptome and host metabolome analysis reveals insights into “ Candidatus Liberibacter asiaticus” population dynamics in the fruit pith of three citrus cultivars with different tolerance

Citation
Li et al. (2024). Microbiology Spectrum 12 (4)
Names
Ca. Liberibacter asiaticus
Abstract
ABSTRACT “ Candidatus Liberibacter asiaticus” (CLas), the causal agent of citrus Huanglongbing (HLB), is able to multiply to a high abundance in citrus fruit pith. However, little is known about the biological processes and phytochemical substances that are vital for CLas colonization and growth in fruit pith. In this study, CLas-infected fruit pith of three citrus cultivars (“Shatangju” mandarin, “Guanxi” pomelo, and

Candidatus Methanosphaera massiliense sp. nov., a methanogenic archaeal species found in a human fecal sample and prevalent in pigs and red kangaroos

Citation
Pilliol et al. (2024). Microbiology Spectrum 12 (2)
Names
Ca. Methanosphaera massiliense
Abstract
ABSTRACT Methanosphaera stadtmanae was the sole Methanosphaera representative to be cultured and detected by molecular methods in the human gut microbiota, further associated with digestive and respiratory diseases, leaving unknown the actual diversity of human-associated Methanosphaera species. Here, a novel Methanosphaera species, Candidatus Methanosphaera massilie

Indications for a genetic basis for big bacteria and description of the giant cable bacterium Candidatus Electrothrix gigas sp. nov

Citation

Names
Electrothrix gigas Electronema Electrothrix Electrothrix communis Ts Electrothrix arhusiensis
Abstract
ABSTRACT Bacterial cells can vary greatly in size, from a few hundred nanometers to hundreds of micrometers in diameter. Filamentous cable bacteria also display substantial size differences, with filament diameters ranging from 0.4 to 8 µm. We analyzed the genomes of cable bacterium filaments from 11 coastal environments of which the resulting 23 new genomes represent 10 novel species-level clades of Candidatus Electrothrix and two clades that putat

The plant pathogenic bacterium Candidatus Liberibacter solanacearum induces calcium-regulated autophagy in midgut cells of its insect vector Bactericera trigonica

Citation
Sarkar et al. (2023). Microbiology Spectrum 11 (5)
Names
“Liberibacter solanacearum”
Abstract
ABSTRACT Autophagy plays an important role against pathogen infection in many organisms; however, little has been done with regard to vector-borne plant and animal pathogens, that sometimes replicate and cause deleterious effects in their vectors. Candidatus Liberibacter solanacearum (CLso) is a fastidious gram-negative phloem-restricted plant pathogen and vectored by the carrot psyllid, Bactericera trigonica . The plant dise

Pathogenicity and Transcriptomic Analyses of Two “ Candidatus Liberibacter asiaticus” Strains Harboring Different Types of Phages

Citation
Zheng et al. (2023). Microbiology Spectrum 11 (3)
Names
Ca. Liberibacter asiaticus
Abstract
Citrus Huanglongbing (HLB), also called citrus greening disease, is a highly destructive disease threatening citrus production worldwide. “ Candidatus Liberibacter asiaticus” is one of the most common putative causal agents of HLB. Phages of “ Ca . Liberibacter asiaticus”

Metabolic Versatility of the FamilyHalieaceaeRevealed by the Genomics of Novel Cultured Isolates

Citation

Names
Litorirhabdus singularis Ts Marimicrobium litorale Litorirhabdus Seongchinamella marina Paraluminiphilus aquimaris Ts Paraluminiphilus
Abstract
Although the familyHalieaceae(OM60/NOR5 clade) is an abundant and cosmopolitan clade widely found in coastal seas and involved in interactions with phytoplankton, a limited number of cultured isolates are available. In this study, we isolated six pure culturedHalieaceaestrains from coastal seawaters and performed a comparative physiological and genomic analysis to give insights into the phylogeny and metabolic potential of this family.

Environmental Factors Affect the Bacterial Community in Diaphorina citri , an Important Vector of “ Candidatus Liberibacter asiaticus”

Citation
Jiang et al. (2023). Microbiology Spectrum 11 (2)
Names
Ca. Liberibacter asiaticus
Abstract
The Asian citrus psyllid (ACP) is an important vector of the HLB pathogen, which is a major threat to citrus production around the world. Bacterial communities harbored by insects could be affected by different environmental factors.

Genetic Diversity of “ Candidatus Liberibacter asiaticus” Based on Four Hypervariable Genomic Regions in China

Citation
Gao et al. (2022). Microbiology Spectrum 10 (6)
Names
Ca. Liberibacter asiaticus
Abstract
The hypervariable genomic regions derived from 35 published C Las genomes were used to decipher the genetic diversity of C Las strains and identify 10 new strains with high variations in prophage regions. Characterizing these variations in the C Las bacteria might provide insight into their evolution and adaptation to host plants and insects in China.

Mutual Exclusion of Methanobrevibacter Species in the Human Gut Microbiota Facilitates Directed Cultivation of a Candidatus Methanobrevibacter Intestini Representative

Citation

Abstract
Methanogens are important hydrogen consumers in the gut and are associated with differing host health. Here, we determine the prevalence and abundance of archaeal species in the guts of a multi-ethnic cohort of healthy Singapore residents.
