Rapid Movement of ‘Candidatus Liberibacter asiaticus’ on ‘Hamlin’ Sweet Orange and ‘Swingle’ Citrumelo Trunks

Citation
Pulici et al. (2023). PhytoFrontiers™ 3 (2)
Names
Ca. Liberibacter asiaticus
Abstract
Huanglongbing (HLB), caused by phloem-limited ‘ Candidatus Liberibacter asiaticus’ (CLas), is the primary limiting factor of production in most citrus regions of the world. After infection, CLas is transported systemically throughout the phloem tissues following the source-sink movement. Split-root rhizoboxes and one-sided graft inoculation above the split trunk was used to understand if the vertical distance of the inoculum source and different anatomical structures (grafted or seedling trees)

Detección de Candidatus Phytoplasma trifolii en plantas de chile para secado con síntomas de yema grande

Citation
Velásquez-Valle et al. (2023). Revista Chapingo Serie Zonas Áridas 21 (2)
Names
Ca. Phytoplasma trifolii
Abstract
El cultivo de chile en el norte centro de México es dañado por la infección causada por Candidatus Phytoplasma trifolii. Los síntomas de la enfermedad incluyen clorosis, deformación foliar, enanismo y sobredesarrollo floral (yema grande) con necrosis de pistilo y anteras. La distribución de yemas grandes en la planta es irregular. Ello sugiere que el patógeno o sus efectores se moverían irregularmente dentro de la planta. Por lo tanto, el objetivo de este trabajo fue determinar la presencia de C

Candidatus Subterrananammoxibiaceae,” a New Anammox Bacterial Family in Globally Distributed Marine and Terrestrial Subsurfaces

Citation
Zhao et al. (2023). Applied and Environmental Microbiology 89 (8)
Names
Ca. Subterrananammoxibiaceae
Abstract
Microorganisms called anammox bacteria are efficient in removing bioavailable nitrogen from many natural and human-made environments. They exist in almost every anoxic habitat where both ammonium and nitrate/nitrite are present.

First report of ‘Candidatus Phytoplasma asteris’ associated with yellowing, scorching and decline of almond trees in India

Citation
Gupta et al. (2023). PeerJ 11
Names
Ca. Phytoplasma Ca. Phytoplasma asteris
Abstract
The almond, a commercially important tree nut crop worldwide, is native to the Mediterranean region. Stone fruit trees are affected by at least 14 ‘Candidatus Phytoplasma’ species globally, among which ‘Candidatus Phytoplasma asteris’ is one of the most widespread phytoplasma infecting Prunus dulcis, causing aster yellows disease. Recently, almond plantations of Nauni region were consistently affected by phytoplasma, as evidenced by visible symptoms, fluorescent microscopic studies and molecular

Microscopic and metatranscriptomic analyses revealed unique cross-domain symbiosis betweenCandidatusPatescibacteria/candidate phyla radiation (CPR) and methanogenic archaea in anaerobic ecosystems

Citation
Kuroda et al. (2023).
Names
“Paceibacteria” Ca. Patescibacteria “Yanofskyibacteriota”
Abstract
AbstractTo verify the parasitic lifestyle ofCandidatusPatescibacteria in the enrichment cultures derived from a methanogenic bioreactor, we applied multifaceted approaches combining cultivation, microscopy, metatranscriptomic, and protein structure prediction analyses. Cultivation experiments with the addition of exogenous methanogenic archaea with acetate, amino acids, and nucleoside monophosphates and 16S rRNA gene sequencing confirmed the increase in the relative abundance ofCa. Patescibacter

Mycoplasma hominis and Candidatus Mycoplasma girerdii in Trichomonas vaginalis: Peaceful Cohabitants or Contentious Roommates?

Citation
Margarita et al. (2023). Pathogens 12 (9)
Names
Ca. Mycoplasma girerdii
Abstract
Trichomonas vaginalis is a pathogenic protozoan diffused worldwide capable of infecting the urogenital tract in humans, causing trichomoniasis. One of its most intriguing aspects is the ability to establish a close relationship with endosymbiotic microorganisms: the unique association of T. vaginalis with the bacterium Mycoplasma hominis represents, to date, the only example of an endosymbiosis involving two true human pathogens. Since its discovery, several aspects of the symbiosis between T. v

Association of SFG Rickettsia massiliae and Candidatus Rickettsia shennongii with Different Hard Ticks Infesting Livestock Hosts

Names
Ca. Rickettsia shennongii
Abstract
Ixodid ticks are responsible for the transmission of various intracellular bacteria, such as the Rickettsia species. Little Information is available about the genetic characterization and epidemiology of Rickettsia spp. The current study was designed to assess the tick species infesting various livestock hosts and the associated Rickettsia spp. in Pakistan. Ticks were collected from different livestock hosts (equids, cattle, buffaloes, sheep, goats, and camels); morphologically identified; and s

Molecular Characterization of Mitogenome of Cacopsylla picta and Cacopsylla melanoneura, Two Vector Species of ‘Candidatus Phytoplasma mali’

Citation
Šafářová et al. (2023). Agronomy 13 (9)
Names
Ca. Phytoplasma mali
Abstract
The mitochondrial genomes of two vector psyllids of the ‘Candidatus Phytoplasma mali’, Cacopsylla picta and C. melanoneura, were sequenced using high-throughput sequencing on the Illumina platform. The main objective of the study was to describe their mitogenome and characterize their genetic variability and the potential changes in the context of the observed global warming. The four complete sequences for C. picta, 14,801 bp and 14,802 bp in length, two complete and one partial sequence for C.

Genomic characterization of a novel, widely distributed Mycoplasma species “Candidatus Mycoplasma mahonii” associated with the brittlestar Gorgonocephalus chilensis

Citation
Aroh et al. (2023). PLOS ONE 18 (8)
Names
Ca. Mycoplasma mahonii
Abstract
Symbiotic relationships are ubiquitous throughout the world’s oceans, yet for many marine organisms, including those in the high latitudes, little is understood about symbiotic associations and functional relationships. From a recently determined genome sequence of a filter-feeding basket star from Argentina, Gorgonocephalus chilensis, we discovered a novel Mycoplasma species with a 796Kb genome (CheckM completeness of 97.9%, G+C content = 30.1%). Similar to other Mycoplasma spp. within Mycoplas

“Candidatus Intestinibacterium parameciiphilum”—member of the “Candidatus Paracaedibacteraceae” family (Alphaproteobacteria, Holosporales) inhabiting the ciliated protist Paramecium

Abstract
AbstractProtists frequently host diverse bacterial symbionts, in particular those affiliated with the order Holosporales (Alphaproteobacteria). All characterised members of this bacterial lineage have been retrieved in obligate association with a wide range of eukaryotes, especially multiple protist lineages (e.g. amoebozoans, ciliates, cercozoans, euglenids, and nucleariids), as well as some metazoans (especially arthropods and related ecdysozoans). While the genus Paramecium and other ciliates
