“…Previous studies also based on molecular detection and in species with significant sample numbers (about 30 birds) reported a prevalence of 11% on average (ranging from Ͻ1 to 38% depending on the species) (21,22,26,32). Regarding Laridae, Christerson et al (26) reported an average prevalence of 17%.…”

“…Cloacal shedding of Chlamydiaceae was detected here in four bird families, including the Sulidae family, never studied before. To date, Chlamydiaceae species had been detected in the Stercoraccidae, Procellaridae, Scolopacidae, Alcidae, Anatidae, Sternidae, and Laridae families (21,22,25,26,32). At the bird species level, the present study revealed the occurrence of Chlamydiaceae in six seabird species, with three of them being more represented in significant numbers (European herring gulls, northern gannets, and common murres, in rank order) and more frequently admitted into WRCs from the French coasts of the Bay of Biscay and the Channel (Union Française des Centres de Sauvegarde, unpublished data).…”

“…Outbreaks of disease with relatively high morbidity and mortality have been described (8,18,24,29,30). Although domestic birds are the most common source of infection in humans, wild birds have also been reported to be a source of C. psittaci infection in the wild (31)(32)(33) or in wildlife rescue centers (WRCs) (25).…”

f Birds are the primary hosts of Chlamydia psittaci, a bacterium that can cause avian chlamydiosis in birds and psittacosis in humans. Wild seabirds are frequently admitted to wildlife rescue centers (WRC) at European Atlantic coasts, for example, in connection with oil spills. To investigate the extent of chlamydial shedding by these birds and the resulting risk for animals in care and the medical staff, seabirds from a French WRC were sampled from May 2011 to January 2014. By use of a quantitative PCR (qPCR), 195 seabirds belonging to 4 orders, 5 families and 13 species were examined, of which 18.5% proved to be Chlamydiaceae positive. The highest prevalence of shedders was found in northern gannets (Morus bassanus) (41%), followed by European herring gulls (Larus argentatus) (14%) and common murres (Uria aalge) (7%). Molecular characterization and phylogenetic analysis of qPCR-positive northern gannet samples revealed two variants of a strain closely related to C. psittaci. In European herring gulls and in one common murre, strains showing high sequence similarity to the atypical Chlamydiaceae-like C122 previously found in gulls were detected. Our study shows that seabirds from the northeastern Atlantic Ocean carry several chlamydial organisms, including C. psittaci-related strains. The staff in WRCs should take protective measures, particularly in the case of mass admissions of seabirds.

“…Although the different species show a high degree of host specificity, other hosts may also be susceptible to infection as these organisms have been isolated from a variety of mammals (4,6,17), birds (10,11), and reptiles (3,6). Chlamydia trachomatis (C. trachomatis) and Chlamydophila pneumoniae (Cp.…”

Infections caused by members of the Chlamydiaceae family have long been underestimated due to the requirement of special laboratory facilities for the detection of this group of intracellular pathogens. Furthermore, new studies of this group of intracellular pathogens have revealed that host specificity of different species is not as clear as recently believed. As most members of the genus Chlamydophila have shown to be transmissible from animals to humans, sensitive and fast detection methods are required. In this study, SYBR green-based real-time assays were developed that detect all members of Chlamydiaceae and differentiate the most prevalent veterinary Chlamydophila species: Cp. psittaci, Cp. abortus, Cp. felis, and Cp. caviae. By adding bovine serum albumin to the master mixes, target DNA could be detected directly in crude lysates of enzymatically digested conjunctival or pharyngeal swabs or tissue specimens from heart, liver, and spleen without further purification. The assays were evaluated on veterinary specimens where all samples were screened using a family-specific PCR, and positive samples were further tested using species-specific PCRs. Cp. psittaci was detected in 47 birds, Cp. felis was found in 10 cats, Cp. caviae was found in one guinea pig, and Cp. abortus was detected in one sheep. The screening assay appeared more sensitive than traditional microscopical examination of stained tissue smears. By combining a fast, robust, and cost-effective method for sample preparation with a highly sensitive family-specific PCR, we were able to screen for Chlamydiaceae in veterinary specimens and confirm the species in positive samples with additional PCR assays.

“…Further, both C. psittaci and non-classified members of Chlamydiae have been found in seabird and penguin species (Herrmann et al 2000(Herrmann et al , 2006Kaleta and Taday 2003;Barbosa and Palacios 2009;Christerson et al 2010); however, the true range and breadth of presence and prevalence are unknown. As is the case for C. psittaci, seabirds may act as transmission vehicles, migrating over large distances and often sharing their habitats with humans.…”

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

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.
