Identification of “ Candidatus Thioturbo danicus,” a Microaerophilic Bacterium That Builds Conspicuous Veils on Sulfidic Sediments

Citation
Muyzer et al. (2005). Applied and Environmental Microbiology 71 (12)
Names
Ca. Thioturbo danicus
Abstract
ABSTRACT Molecular analysis of bacteria enriched under in situ-like conditions and mechanically isolated by micromanipulation showed that a hitherto-uncultivated microaerophilic bacterium thriving in oxygen-sulfide counter-gradients (R. Thar and M. Kühl, Appl. Environ. Microbiol. 68:6310-6320, 2000) is affiliated with the ε-subdivision of the Proteobacteria . The affiliation was confirmed by the use of whole-cell hybridization with newly designed s

Evaluation of Antibiotic Treatment against “ Candidatus Helicobacter suis” in a Mouse Model

Citation
Hellemans et al. (2005). Antimicrobial Agents and Chemotherapy 49 (11)
Names
Ca. Helicobacter suis
Abstract
ABSTRACT “ Helicobacter heilmannii ” (proposed name) type 1 colonizes the human stomach. It has been shown to be identical to“ Candidatus Helicobacter suis,” a Helicobacter species colonizing the stomachs of >60% of slaughter pigs. This bacterium has not been isolated in vitro until now. Antibiotic susceptibility testing of “ Candidatus Helicobacter suis” has not been carried

‘Candidatus Phytoplasma graminis' and ‘Candidatus Phytoplasma caricae’, two novel phytoplasmas associated with diseases of sugarcane, weeds and papaya in Cuba

Citation

Names
Ca. Phytoplasma graminis Ca. Phytoplasma caricae
Abstract
During 2003, surveys of sugarcane yellow leaf disease and papaya bunchy top-like disease were carried out on plantations in Havana province, Cuba, to determine the roles of weeds and Auchenorrhyncha insects in the epidemiology of these diseases. More than 250 plant and insect samples were collected and indexed by using a nested PCR for phytoplasma 16S rDNA with the generic primer pairs P1/P7 and R16F2n/R16R2. The PCR products were further characterized by restriction fragment length polymorphism

Diversity of “ Candidatus Liberibacter asiaticus,” Based on the omp Gene Sequence

Citation
Bastianel et al. (2005). Applied and Environmental Microbiology 71 (11)
Names
Ca. Liberibacter asiaticus
Abstract
ABSTRACT Huanglongbing (yellow dragon disease) is a destructive disease of citrus. The etiological agent is a noncultured, phloem-restricted alpha-proteobacterium, “ Candidatus Liberibacter africanus” in Africa and “ Candidatus Liberibacter asiaticus” in Asia. In this study, we used an omp -based PCR-restriction fragment length polymorphism (RFLP) approach to analyze the genetic variability of “

‘Candidatus Protochlamydia amoebophila’, an endosymbiont of Acanthamoeba spp

Citation
Collingro et al. (2005). International Journal of Systematic and Evolutionary Microbiology 55 (5)
Names
Ca. Protochlamydia amoebophila
Abstract
The obligately intracellular coccoid bacterium UWE25, a symbiont of Acanthamoeba spp., was previously identified as being related to chlamydiae based upon the presence of a chlamydia-like developmental cycle and its 16S rRNA gene sequence. Analysis of its complete genome sequence demonstrated that UWE25 shows many characteristic features of chlamydiae, including dependency on host-derived metabolites, composition of the cell envelope and the ability to thrive as an energy parasite within the cel

‘Candidatus Liberibacter americanus’, associated with citrus huanglongbing (greening disease) in São Paulo State, Brazil

Citation
Teixeira et al. (2005). International Journal of Systematic and Evolutionary Microbiology 55 (5)
Names
Ca. Liberibacter americanus
Abstract
Symptoms of huanglongbing (HLB) were reported in São Paulo State (SPS), Brazil, in March 2004. In Asia, HLB is caused by ‘Candidatus Liberibacter asiaticus' and in Africa by ‘Candidatus Liberibacter africanus’. Detection of the liberibacters is based on PCR amplification of their 16S rRNA gene with specific primers. Leaves with blotchy mottle symptoms characteristic of HLB were sampled in several farms of SPS and tested for the presence of liberibacters. ‘Ca. L. asiaticus' was detected in a smal
