‘Candidatus Aquirestis calciphila’ and ‘Candidatus Haliscomenobacter calcifugiens’, filamentous, planktonic bacteria inhabiting natural lakes

Citation
Hahn et al. (2007). International Journal of Systematic and Evolutionary Microbiology 57 (5)
Names
Ca. Haliscomenobacter calcifugiens Ca. Aquirestis calciphila
Abstract
Filamentous bacteria frequently occurring in the pelagic zone of natural freshwater lakes and ponds were previously identified as being related to Haliscomenobacter hydrossis based upon their 16S rRNA gene sequences. These bacteria exhibit a specific morphology characterized by the formation of straight, stick-like filaments of variable length (5 to >100 μm) and quite stable, but narrow, width (0.25 to 0.35 μm). Bacteria with these morphological characteristics form a monophyletic but broad p

Transmission of ‘Candidatus Phytoplasma aurantifolia’ to Bakraee (Citrus reticulata Hybrid) by Feral Hishimonus phycitis Leafhoppers in Iran

Names
Ca. Phytoplasma aurantifolia
Abstract
Witches'-broom disease of lime (WBDL) caused by ‘Candidatus Phytoplasma aurantifolia’ is a devastating disease in the Sultanate of Oman, United Arab Emirates, and southern Iran. The disease primarily affects lime (Citrus aurantifolia), but in Iran, it is also found in bakraee, a natural C. reticulata hybrid. The disease has been experimentally transmitted from lime to several citrus cultivars by grafting and to a number of herbaceous hosts by dodder. However, the natural vector of ‘Ca. P. auran

First Report of a Natural Infection of Opuntia sp. by a ‘Candidatus Phytoplasma asteris’-Related Phytoplasma in China

Citation
Wei et al. (2007). Plant Disease 91 (4)
Names
Ca. Phytoplasma asteris
Abstract
Cacti (Opuntia spp.) are perennial, evergreen, succulent plants native to arid areas of the Americas. Because of their aesthetic appearance, many cacti have been cultivated and introduced to other parts of the world as ornamentals. Cacti are susceptible to phytoplasma infections and develop witches'-broom (WB) disease. Currently, all reported cactus WB cases are associated with infections by phytoplasmas in the peanut witches'-broom group (16SrII) (1,2,4). During a phytoplasma diversity survey

“ Candidatus Helicobacter heilmannii” from a Cynomolgus Monkey Induces Gastric Mucosa-Associated Lymphoid Tissue Lymphomas in C57BL/6 Mice

Names
Ca. Helicobacter heilmannii
Abstract
ABSTRACT Both Helicobacter pylori and “ Candidatus Helicobacter heilmannii” infections are associated with peptic ulcers, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphomas. However, good animal models of H. pylori clinical diseases are rare. In this study, we aimed to establish an animal model of “ Candidatus Helicobacter heilmannii” gastric

Methanobrevibacter millerae sp. nov. and Methanobrevibacter olleyae sp. nov., methanogens from the ovine and bovine rumen that can utilize formate for growth

Names
“Methanocatella millerae”
Abstract
Four formate-utilizing methanogens were isolated from ovine (strain KM1H5-1PT) and bovine (strains AK-87, OCP and ZA-10T) rumen contents. Based on 16S rRNA gene sequence analysis, the methanogen strains were found to belong to the order Methanobacteriales in the genus Methanobrevibacter. Strains ZA-10T and KM1H5-1PT gained energy for growth by the reduction of CO2 to CH4 using H2 or formate exclusively as electron donors. Increasing formate concentrations to 220 mM in batch cultures increased th
