“…The prevalence of C. psittaci among wild birds and the risk of zoonotic infection appear to be low (Olsen et al 1998;Christerson et al 2010;Blomqvist et al 2012a, b), but may vary depending on species and location (Williams et al 1998;Telfer et al 2005;Herrmann et al 2006). Previous studies of penguins have not detected C. psittaci DNA (Travis et al 2006;González-Acuña et al 2013), but antibodies to C. psittaci have been found in 28 % of Adélie penguins (Pygoscelis adeliae) (Moore and Cameron 1969), in 62 % of Humboldt penguins (Spheniscus humboldti) (Smith et al 2008) and 89 % of Galapagos penguins (Spheniscus mendiculus) (Travis et al 2006).…”

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

et al. 2015

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

“…Other sources of infection are handling the plumage and tissues of infected birds, a bite from an infected bird, and in rare cases mouth-to-beak contact Smith et al, 2005). Even a short exposure to birds or bird wastes, as well as seemingly unrelated activities like gardening or lawn-mowing without a grass catcher, can result in infection (Telfer et al, 2005;Williams et al, 1998). Person-to-person transmission is possible but is considered rare (Hughes et al, 1997;Ito et al, 2002;Williams et al, 1998).…”

“…The role of Chlamydiaceae as pathogens in humans, mammalians and domestic birds is well established (Kaltenböeck et al 1993). However, little information is available on the role of wild birds as reservoirs of Chlamydiaceae (Yung and Grayson 1988;Williams et al 1998;Kaleta and Taday 2003;Zweifel et al 2009). This lack of data is at least partly due to the problems associated with the diagnosis of chlamydial infections because of the difficulties of culturing these obligate intracellular bacteria.…”

Few studies have investigated the role of raptors as natural reservoirs of Chlamydiaceae spp. and the preferred anatomical sites where these bacteria can be detected in non-symptomatic wild birds. We investigated the occurrence of Chlamydiaceae in 54 non-symptomatic adult free-living birds belonging to 14 species sampled upon reception in a raptor rehabilitation centre in Spain, and ten juvenile birds from five species born and reared in the centre for subsequent release into the wild. Swabs from conjunctivae, choanae and cloacae were taken to detect Chlamydiaceae DNA by a family-specific polymerase chain reaction (PCR) and a nested genus-and species-specific PCR. Chlamydiaceae DNA was detected in adult raptors belonging to 12 species (85.7%), mainly in conjunctival (40.6%) and, to a lesser extent, choanal (17.2%) swabs, but never in cloacal samples. Neither the genus nor the species of Chlamydiaceae could be confirmed by the nested PCR assay. Our results suggest that most of the raptor species investigated, especially the Common Kestrel (Falco tinnunculus) and Eurasian Griffon Vulture (Gyps fulvus), can be natural reservoirs of Chlamydiaceae spp. in the wild. Failure to identify the organisms at genus and species level might have been due to the poor quality and low concentration of DNA in the samples or to the presence of hitherto unclassified Chlamydiaceae species.
