First Report of “Candidatus Liberibacter psyllaurous” or “Ca. Liberibacter solanacearum” Associated with Severe Foliar Chlorosis, Curling, and Necrosis and Tuber Discoloration of Potato Plants in Honduras

Ca. Liberibacter psyllaurous “Liberibacter solanacearum”
Abstract
From 2006 to 2009, all commercial potato fields in Azacualpa F.M. Honduras were heavily infested with the potato psyllid Bactericera cockerelli (Sulc.). Plants exhibited interveinal chlorosis, vein-greening, downward curling, stunting, above ground tuber formation, and brownish flecks in some tubers. Disease incidence ranged from 50 to 95%. Leaf samples and psyllids were collected from seven fields in two potato-growing regions of Honduras. Total DNA was purified from the leaves of 30 symptomat

Screening Molecules for Control of Citrus Huanglongbing Using an Optimized Regeneration System for ‘Candidatus Liberibacter asiaticus’-Infected Periwinkle (Catharanthus roseus) Cuttings

Ca. Liberibacter asiaticus
Abstract
Citrus huanglongbing is one of the most destructive diseases of citrus worldwide. The disease is associated with three different species of ‘Candidatus Liberibacter’, of which ‘Ca. L. asiaticus’ is the most widely distributed. An optimized system using ‘Ca. L. asiaticus’-infected periwinkle cuttings was developed to screen chemical compounds effective for controlling the bacterial population while simultaneously assessing their phytotoxicity. The optimal regeneration conditions were determined

The Genome of the Amoeba Symbiont “ Candidatus Amoebophilus asiaticus” Reveals Common Mechanisms for Host Cell Interaction among Amoeba-Associated Bacteria

Names
Ca. Amoebophilus asiaticus
Abstract
ABSTRACT Protozoa play host for many intracellular bacteria and are important for the adaptation of pathogenic bacteria to eukaryotic cells. We analyzed the genome sequence of “ Candidatus Amoebophilus asiaticus,” an obligate intracellular amoeba symbiont belonging to the Bacteroidetes . The genome has a size of 1.89 Mbp, encodes 1,557 proteins, and shows massive proliferation of IS elements (24% of all genes), although the g

Thiohalobacter thiocyanaticus gen. nov., sp. nov., a moderately halophilic, sulfur-oxidizing gammaproteobacterium from hypersaline lakes, that utilizes thiocyanate

Abstract
A moderately halophilic, obligately chemolithoautotrophic, sulfur-oxidizing bacterium, designated strain HRh1T, was obtained from mixed sediment samples from hypersaline chloride–sulfate lakes in the Kulunda Steppe, in south-western Siberia (Russia), using aerobic enrichment culture at 1 M NaCl with thiocyanate as substrate. Cells of the isolate were short, non-motile rods with a Gram-negative type of cell wall. The bacterium was an obligate aerobe capable of chemolithoautotrophic growth with th
