| amoebal host-range, host-free survival and disinfection susceptibility of environmental chlamydiae as compared to chlamydia trachomatis. | the term "chlamydia-like organisms" encompasses obligate intra-cellular bacterial species phylogenetically close to chlamydiaceae. most are associated with free-living amoebae and several could be responsible for respiratory tract infections and abortion in human and animals. despite increasing concern about their pathogenic role, the prevalence, biodiversity, and ecology of chlamydia-related bacteria still remain largely unknown. in this study, six members of the chlamydiales were tested, inclu ... | 2011 | 22141597 |
| estrella lausannensis, a new star in the chlamydiales order. | originally, the chlamydiales order was represented by a single family, the chlamydiaceae, composed of several pathogens, such as chlamydia trachomatis, chlamydia pneumoniae, chlamydia psittaci and chlamydia abortus. recently, 6 new families of chlamydia-related bacteria have been added to the chlamydiales order. most of these obligate intracellular bacteria are able to replicate in free-living amoebae. amoebal co-culture may be used to selectively isolate amoeba-resisting bacteria. this method a ... | 2011 | 21816232 |
| 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 |
| 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 |
| criblamydia sequanensis, a new intracellular chlamydiales isolated from seine river water using amoebal co-culture. | accumulating evidence supports a role for chlamydia-related organisms as emerging pathogens for human and animals. assessment of their pathogenicity requires strain availability, at least for animal models and serological studies. as these obligate intracellular species are able to grow inside amoebae, we used co-culture with acanthamoeba castellanii in an attempt to recover new chlamydia-related species from river water. we isolated two strains from eight water samples. the first strain is a ne ... | 2006 | 17107554 |
