Abstract
Huanglongbing (HLB) disease, also known as citrus greening disease, was first reported in the US in 2005. Since then, the disease has decimated the citrus industry in Florida, resulting in billions of dollars in crop losses and the destruction of thousands of acres of citrus groves. The causative agent of citrus greening disease is the phloem limited pathogen Candidatus Liberibacter asiaticus. As it has not been cultured, very little is known about the structural biology of the organism. Liberib

The status Candidatus for uncultured taxa of Bacteria and Archaea: SWOT analysis

Citation

Abstract
The status Candidatus was introduced to bacterial taxonomy in the 1990s to accommodate uncultured taxa defined by analyses of DNA sequences. Here I review the strengths, weaknesses, opportunities and threats (SWOT) associated with the status Candidatus in the light of a quarter century of use, twinned with recent developments in bacterial taxonomy and sequence-based taxonomic discovery. Despite ambiguities as to its scope, philosophical objections to its use and practical problems in implementat

Relevance of Candidatus Nitrotoga for nitrite oxidation in technical nitrogen removal systems

Abstract
Abstract Many biotechnological applications deal with nitrification, one of the main steps of the global nitrogen cycle. The biological oxidation of ammonia to nitrite and further to nitrate is critical to avoid environmental damage and its functioning has to be retained even under adverse conditions. Bacteria performing the second reaction, oxidation of nitrite to nitrate, are fastidious microorganisms that are highly sensitive against disturbances. One importan

‘Candidatus Xiphinematincola pachtaicus' gen. nov., sp. nov., an endosymbiotic bacterium associated with nematode species of the genus Xiphinema (Nematoda, Longidoridae)

Names
Ca. Glomeribacter gigasporarum Ca. Xiphinematincola pachtaicus Ca. Xiphinematincola
Abstract
An intracellular bacterium, strain IAST, was observed to infect several species of the plant-parasitic nematode genus Xiphinema (Xiphinema astaregiense, Xiphinema incertum, Xiphinema madeirense, Xiphinema pachtaicum, Xiphinema parapachydermum and Xiphinema vallense). The bacterium could not be recovered on axenic medium. The 16S rRNA gene sequence of IAST was found to be new, being related to the family Burkholderiaceae, class Betaproteobacteria. Fungal endosymbionts

Molecular detection of Theileria species, Anaplasma species, Candidatus Mycoplasma haemobos, Trypanosoma evansi and first evidence of Theileria sinensis-associated bovine anaemia in crossbred Kedah-Kelantan x Brahman cattle

Ca. Mycoplasma haemobos
Abstract
Abstract Background Serious disease outbreaks in cattle are usually associated with blood pathogens. This study aims to detect blood pathogens namely Theileria species, Anaplasma species, Candidatus Mycoplasma haemobos and Trypanosoma evansi, and determine their phylogenetic relationships and haemato-biochemical abnormalities in naturally infected cattle. Methods Molecular analysis was achieved by PCR amplification an

Abstract
La papa Solanum tuberosum L pertenece a la familia de las solanáceas, es el cuarto cultivo sembrado en más de 100 países incluyendo Nicaragua, en este país existe un consumo por persona de hasta unos 8 kg anuales, la papa se cultiva en Nicaragua entre 800 a 1 200 hectáreas y se obtiene una producción que representa de 35 % a 40 % de la demanda nacional. El objetivo del presente estudio fue determinar la fluctuación poblacional de  Bactericera cockerelli e incidencia de punta morada (Candidatus l
