Citation

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

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

‘Candidatus Rickettsia andeanae’ and Probable Exclusion of Rickettsia parkeri in Ticks from Dogs in a Natural Area of the Pampa Biome in Brazil

Abstract
Spotted fever illness caused by the tick-borne pathogen Rickettsia parkeri has emerged in the Pampa biome in southern Brazil, where the tick Amblyomma tigrinum is implicated as the main vector. Because domestic dogs are commonly parasitized by A. tigrinum, this canid is also a suitable sentinel for R. parkeri-associated spotted fever. Herein, we investigate rickettsial infection in ticks, domestic dogs and small mammals in a natural reserve of the Pampa biome in southern Brazil. The ticks A. tig

Identificación de proteínas en Candidatus Liberibacter asiaticus para desarrollar un método de detección inmunoenzimático

Citation
Rodríguez-Quibrera et al. (2022). Revista Mexicana de Ciencias Agrícolas 13 (8)
Names
Ca. Liberibacter asiaticus
Abstract
El objetivo de este trabajo fue identificar en el genoma de Candidatus Liberibacter asiaticus (CLas), proteínas de membrana externa con potencial para el desarrollo y optimización de un método de detección inmunoenzimático. El estudio se realizó durante 2019 y se utilizó el servidor web Predict Protein, así como las bases de datos HhPred/HhSearch y Pfam. Se detectaron 52 proteínas de membrana externa en el genoma completo de CLas, de las cuales, 11 no habían sido caracterizadas previamente. Los

Nuevos haplotipos de Diaphorina citri, vector de Candidatus Liberibacter en zonas citrícolas de México

Abstract
Se identificaron nuevos haplotipos de Diaphorina citri también conocido como el psílido asiático de los cítricos, denominados DcitACC-1, DcitACC-2 y DcitACC-3. Los estudios se basaron en la amplificación de ADN del gen COI mitocondrial y se utilizaron individuos de diferentes zonas citrícolas del país, en algunas zonas productoras del país no se han realizado muestreos con anterioridad, específicamente en los municipios de Acatlán de Pérez, Oaxaca, Misantla y Tantoyuca, Veracruz y Huejutla, Hida

Detection and Multigene Typing of ‘Candidatus Phytoplasma solani’-Related Strains Infecting Tomato and Potato Plants in Different Regions of Turkey

Citation
Çağlar, Şimşek (2022). Pathogens 11 (9)
Names
Ca. Phytoplasma solani
Abstract
‘Candidatus Phytoplasma solani’ (‘Ca. P. solani’) is a crop pathogen that is a member of the 16SrXII-A ribosomal subgroup. It is also known as stolbur phytoplasma and causes yield losses in several important crops, especially in Solanaceous crops. Different strains of the pathogen are regularly reported all over the world, particularly in the Mediterranean region. In this study, the determination of genetic diversity for the pathogen infecting tomatoes and potatoes was carried out by using multi

Survey for ‘Candidatus Liberibacter’ and ‘Candidatus Phytoplasma’ in Citrus in Chile

Citation
Quiroga et al. (2021). Pathogens 11 (1)
Names
Ca. Phytoplasma Liberibacter
Abstract
The considerable economic losses in citrus associated with ‘Candidatus Liberibacter’ and ‘Candidatus Phytoplasma’ presence have alerted all producing regions of the world. In Chile, none of these bacteria have been reported in citrus species. During the years 2017 and 2019, 258 samples presenting symptoms similar to those associated with the presence of these bacteria were examined. No detection of ‘Ca. Liberibacter’ associated with “huanglongbing” disease was obtained in the tested samples; the

Application of TaqMan Real-Time PCR for Detecting ‘Candidatus Arsenophonus Phytopathogenicus’ Infection in Sugar Beet

Citation

Names
Ca. Arsenophonus phytopathogenicus Arsenophonus
Abstract
The γ-proteobacterium ‘Candidatus Arsenophonus phytopathogenicus’ is assigned as the major pathogen of “Syndrome des basses richesses”, a sugar beet disease characterised by a reduction in the sugar content of taproots and biomass yield. Despite the economic impact of this bacteriosis, diagnostics for this important pathogen currently rely on end-point PCR detection. Herein, we introduce a TaqMan qPCR for diagnostics of the agent targeting genes encoding a heat shock protein of the Hsp20 family

Interactions between Indigenous Endophyte Bacillus subtilis L1-21 and Nutrients inside Citrus in Reducing Huanglongbing Pathogen Candidatus Liberibacter Asiaticus

Abstract
Huanglongbing (HLB) pathogen Candidatus Liberibacter asiaticus (CLas) brings a great concern about the phloem nutrient transport in diseased plants. There is an urgent need to find the best management strategies to reduce the losses in the citrus industry worldwide. Endophytic bacteria are negatively affected by CLas pathogen, and these endophytes are associated with improved availability of nutrients and pathogen resistance. This study underpins the relationship between CLas pathogen, endophyte
