Chlamydiaceae-like bacterium, but no Chlamydia psittaci, in sea birds from Antarctica

摘要: Within the growing order of Chlamydiales, there are a number pathogens. One is Chlamydia psittaci, zoonotic pathogen, with birds as natural hosts that may be transmitted to humans and cause severe respiratory disease, psittacosis. The prevalence this pathogen in Antarctic almost unknown well ramifications its potential spread naive bird populations. To investigate chlamydia organisms, cloacal fecal samples were collected from 264 penguins 263 seabirds on Peninsula Southern Chile. No C. psittaci could detected by 23S rRNA real-time PCR. However, DNA sequencing 16S 298-bp signature sequence revealed Chlamydiaceae-like bacterium previously found subarctic zone, demonstrating not yet fully characterized widespread. In conclusion, among wild seems low, but other types chlamydial organisms common. Further studies required taxonomically define finally understand role these non-classified Chlamydiae.
