Complete Genome Sequence of Strain JB001, a Member of Saccharibacteria Clade G6 (“ Candidatus Nanogingivalaceae”)

Citation

Names
“Nanogingivalaceae”
Abstract
At least 6 highly diverse clades of Saccharibacteria inhabit the human oral cavity. However, all oral Saccharibacteria strains with currently available complete genome sequences or cultured isolates belong to clade G1, leaving clades G2 through G6 poorly understood. Here, a complete genome sequence of JB001, a clade G6 (“ Candidatus Nanogingivalaceae”) Saccharibacteria strain, is reported.

First report of 'Candidatus Phytoplasma trifolii' associated with leaf reddening and upright growth in pears (Pyrus communis L.)

Citation
Usta et al. (2021). Plant Protection Science 57 (No. 3)
Names
Ca. Phytoplasma trifolii
Abstract
The natural occurrence of 'Candidatus Phytoplasma trifolii' in pear trees (Pyrus communis Linnaeus) is reported here for the first time. In 2017, a total of thirty-five pear trees, two of them exhibiting leaf rolling along the midvein, reddening, bushy appearance, and upright growth symptoms were sampled in different locations in Van province, Turkey. The total deoxyribonucleic acid was extracted from symptomatic and asymptomatic plants. The purified DNA served as a template in nested polymerase

High Co-Infection Rate of Trichomonas vaginalis and Candidatus Mycoplasma Girerdii in Gansu Province, China

Citation
Xu et al. (2021). Healthcare 9 (6)
Names
Ca. Mycoplasma girerdii
Abstract
Trichomonas vaginalis (Tv) is a flagellated protist parasite that infects the human urogenital tract. The symbiotic relationship between Tv and Mycoplasma hominis has been reported. Recent studies have identified a new Mycoplasma strain, Candidatus Mycoplasma girerdii (Ca. M. girerdii), present in the vaginal secretions of women and have shown that this strain may be related to trichomoniasis. Here, we evaluated the presence of Tv, M. hominis and Ca. M. girerdii in 312 clinical samples from adul

Early Population Dynamics of “Candidatus Liberibacter asiaticus” in Susceptible and Resistant Genotypes After Inoculation With Infected Diaphorina citri Feeding on Young Shoots

Names
Ca. Liberibacter asiaticus
Abstract
Huanglongbing is a highly destructive citrus disease associated with “Candidatus Liberibacter asiaticus” (Las), a phloem−limited and non-culturable bacterium, naturally transmitted by the psyllid Diaphorina citri. Although diverse approaches have been used to understand the molecular mechanisms involved in the pathogen–host interaction, such approaches have focused on already infected and/or symptomatic plants, missing early events in the initial days post-inoculation. This study aimed to identi

Molecular Detection of Novel Borrelia Species, Candidatus Borrelia javanense, in Amblyomma javanense Ticks from Pangolins

Citation

Names
Ca. Borrelia javanense
Abstract
A novel Borrelia species, Candidatus Borrelia javanense, was found in ectoparasite ticks, Amblyomma javanense, from Manis javanica pangolins seized in anti-smuggling operations in southern China. Overall, 12 tick samples in 227 (overall prevalence 5.3%) were positive for Candidatus B. javanense, 9 (5.1%) in 176 males, and 3 (5.9%) in 51 females. The phylogenetic analysis, based on the 16S rRNA gene and the flagellin gene sequences of the Borrelia sp., exhibited strong evidence that Candidatus B.

The Mechanism of Citrus Host Defense Response Repression at Early Stages of Infection by Feeding of Diaphorina citri Transmitting Candidatus Liberibacter asiaticus

Names
Ca. Liberibacter asiaticus
Abstract
Citrus Huanglongbing (HLB) is the most devastating disease of citrus, presumably caused by “Candidatus Liberibacter asiaticus” (CaLas). Although transcriptomic profiling of HLB-affected citrus plants has been studied extensively, the initial steps in pathogenesis have not been fully understood. In this study, RNA sequencing (RNA-seq) was used to compare very early transcriptional changes in the response of Valencia sweet orange (VAL) to CaLas after being fed by the vector, Diaphorina citri (Asia

Alborzia kermanshahica gen. nov., sp. nov. (Chroococcales, Cyanobacteria), isolated from paddy fields in Iran

Citation
Nowruzi, Soares (2021). International Journal of Systematic and Evolutionary Microbiology 71 (6)
Names
Alborzia kermanshahica T Alborzia
Abstract
In Iran, polyphasic studies of unicellular cyanobacteria are still scarce, with more emphasis being placed on filamentous cyanobacteria in paddy fields and fresh water regions. In an effort to increase the knowledge of the diversity of unicellular cyanobacteria from paddy fields in Iran, we have isolated and characterized a new unicellular cyanobacterium strain. The strain was studied using a polyphasic approach based on morphological, ecological and phylogenetic analyses of the 16S–23S ITS rRNA

Candidatus Phytoplasma pini (pine witches'-broom phytoplasma)

Citation
Davis, Zhao (2021).
Names
Ca. Phytoplasma pini
Abstract
Abstract 'Ca. Phytoplasma pini' is a member of phytoplasma 16S rRNA gene RFLP group XXI, subgroup XXI-A. It has been identified in a number of European countries, including Germany, Poland, Lithuania, Spain, Czech Republic and Croatia. Outside of Europe it has been identified in China and Mozambique. A related strain has also been identified in Maryland, USA. In the USA, favourable climatic conditions and wide availability of potential host plants of the phytoplasma, suggest that the pot

Abstract
Abstract.We tried to determine the epidemiology and species of human dirofilariasis observed at two tertiary care hospitals in Kerala. We searched the hospital database to identify cases of dirofilariosis from January 2005 to March 2020. Along with human isolates, one dog Dirofilaria isolate was also subjected to PCR and sequencing of pan filarial primers cytochrome oxidase subunits 1 and 12S rDNA. We documented 78 cases of human dirofilariosis. The orbit, eyelid, and conjunctiva were the most c
