| 'candidatus rhabdochlamydia porcellionis', an intracellular bacterium from the hepatopancreas of the terrestrial isopod porcellio scaber (crustacea: isopoda). | intracellular bacteria were observed in the hepatopancreas of the terrestrial isopod porcellio scaber. comparative 16s rrna gene sequence analysis and electron microscopic observations were used to determine the taxonomic position of these intracellular bacteria. phylogenetic analysis and a complex developmental cycle affiliate these bacteria to the order chlamydiales, within which they form a distinctive lineage, close to the family simkaniaceae. they share <92 % 16s rrna gene sequence similari ... | 2004 | 15023973 |
| pathogenic potential of novel chlamydiae and diagnostic approaches to infections due to these obligate intracellular bacteria. | novel chlamydiae are newly recognized members of the phylum chlamydiales that are only distantly related to the classic chlamydiaceae, i.e., chlamydia and chlamydophila species. they also exhibit an obligate biphasic intracellular life cycle within eukaryote host cells. some of these new chlamydiae are currently considered potential emerging human and/or animal pathogens. parachlamydia acanthamoebae and simkania negevensis are both emerging respiratory human pathogens, waddlia chondrophila could ... | 2006 | 16614250 |
| 'candidatus rhabdochlamydia crassificans', an intracellular bacterial pathogen of the cockroach blatta orientalis (insecta: blattodea). | the genus rickettsiella comprises various intracellular bacterial pathogens of arthropods, exhibiting a chlamydia-like developmental cycle. species may be divided into two main groups, the r. popilliae-r. grylli group and the r. chironomi group. previous phylogenetic studies based on the 16s ribosomal rna encoding gene showed that two rickettsiella species, one from each group, belong in reality to two distantly related lineages, the gamma-proteobacteria (r. grylli) and the chlamydiales ('candid ... | 2007 | 16934426 |
| emerging role of chlamydia and chlamydia-like organisms in adverse pregnancy outcomes. | this review considers the roles of chlamydia spp. and newly identified chlamydia-like organisms in miscarriage, stillbirths and preterm labour in both animals and humans. | 2008 | 18192789 |
| chlamydia-like bacteria in respiratory samples of community-acquired pneumonia patients. | chlamydia-like bacteria, obligate intracellular relatives of chlamydia trachomatis and chlamydophila pneumoniae, are widely distributed in nature. using a two-step nested and semi-nested pcr approach targeting the 16s rrna gene, we found dna of chlamydia-like bacteria in respiratory samples from patients with community-acquired pneumonia. of 387 cases tested, four (1.03%) tested positive if only sequences showing less than 99.9% 16s rrna gene sequence similarity to known chlamydiae were consider ... | 2008 | 18312573 |
| novel chlamydiales strains isolated from a water treatment plant. | chlamydiae are obligate intracellular bacteria infecting free-living amoebae, vertebrates and some invertebrates. novel members are regularly discovered, and there is accumulating evidence supporting a very important diversity of chlamydiae in the environment. in this study, we investigated the presence of chlamydiae in a drinking water treatment plant. samples were used to inoculate acanthamoeba monolayers (acanthamoeba co-culture), and to recover autochthonous amoebae onto non-nutritive agar. ... | 2009 | 18793313 |
| parachlamydia acanthamoebae, an emerging agent of pneumonia. | parachlamydia acanthamoebae is a chlamydia-like organism that easily grows within acanthamoeba spp. thus, it probably uses these widespread free-living amoebae as a replicative niche, a cosmopolite aquatic reservoir and a vector. a potential role of p. acanthamoebae as an agent of lower respiratory tract infection was initially suggested by its isolation within an acanthamoeba sp. recovered from the water of a humidifier during the investigation of an outbreak of fever. additional serological an ... | 2009 | 19220336 |

| chlamydia-related bacteria in respiratory samples in finland. | chlamydiarelated bacteria, new members of the order chlamydiales, are suggested to be associated with respiratory disease. we used real-time pcr to investigate the prevalence of parachlamydia acanthamoebae, protochlamydia spp., rhabdochlamydia spp., simkania negevensis and waddlia chondrophila in samples taken from patients with suspected respiratory tract infections. of the 531 samples analyzed, the subset of 136 samples contained 16 (11.8%) samples positive for rhabdochlamydia spp. dna. p. aca ... | 2011 | 21612765 |
