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

Abstract: 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 … Show more

“…Information on total number of chicks sampled, number of positives, age of chicks at sampling, and type of PCR performed are not included in the reports. An unclassified Chlamydiaceae -like bacteria was identified by real-time PCR from fresh Southern Giant Petrel faeces (1/6) in the Antarctic Peninsula (Isaksson et al 2015). I. uriae ticks (3/41) from Black-browed Albatross breeding in Campbell Island, New Zealand, were positive for the vector-borne bacteria Borrelia garinii DNA by PCR (Olsen et al 1995).…”

“…The failure to isolate C. psittaci despite relatively high CFT seroprevalences (Travis et al 2006; Gonzá lez-Acuña et al 2013) suggests cross-reactivity with antigenicallysimilar organisms. Chlamydia psittaci was demonstrated to infect captive Little Penguins (Eudyptula minor; Gedye et al 2018), but other yet unidentified Chlamydiales are also known to infect wild penguins (Isaksson et al 2015). A high prevalence (32.3%) of Chlamydiaceae species other than C. psittaci was recently detected in cloacal swabs of Magellanic Penguins in Argentina, and some of these were related to a strain previously found in feces of seabirds from the northern hemisphere (Gallo-Vaulet et al 2017).…”

“…The genotypes described were identical to poultry strains from a sympatric area, suggesting a potential cross-host transmission event and/or a genotype specific to this region. Adding to this list of novel avian chlamydial species, several novel unclassified chlamydial species were also reported in faecal specimens in wild seabirds such as penguins and gulls [28] , [29] . These taxa are closely related despite their geographically distinct locations.…”
