First Report of Caprine Abortions Due to Chlamydia Abortus in Argentina

In this paper, we describe an abortion outbreak in goats caused by Chlamydia abortus. Seventy out of 400 goats aborted. Placental smears stained with modified Ziehl-Neelsen stain showed many chlamydia-like bodies within trophoblasts. One stillborn fetus was necropsied and the placenta was examined. No gross lesions were seen in the fetus, but the inter-cotyledonary areas of the placenta were thickened and covered by fibrino-sup- purative exudate. The most consistent microscopic finding was found in the placenta and consisted of fibrinoid necrotic vasculitis, with mixed inflammatory infiltration in the tunica media. Immunohistochemistry of the pla- centa was positive for Chlamydia spp. The results of polymerase chain reaction targeting 23S rRNA gene per- formed on placenta were positive for Chlamydia spp. An analysis of 417 amplified nucleotide sequences revealed 99% identity to those of C. abortus pm225 (GenBank AJ005617) and pm112 (GenBank AJ005613) isolates. To the best of our knowledge, this is the first report of abortion associated with C. -

Molecular studies have revealed that this pathogen is genetically diverse with certain isolates In vitro growth linked to different disease outcomes. Limited in vitro or in vivo data exist to support these observations, further Genetically distinct hampering efforts to improve our understanding of C. pecorum pathogenesis. In this study, we evaluated whether Developmental cycle genetically distinct C. pecorum isolates (IPA, E58, 1710S, W73, JP-1-751) display different in vitro growth phenotypes in different mammalian epithelial and immune cells. In McCoy cells, shorter lag phases were ob- served for W73 and JP-1-751 isolates. Significantly smaller inclusions were observed for the naturally plasmid- free E58 isolate. C. pecorum isolates of bovine (E58) and ovine origin (IPA, W73, JP-1-751) grew faster in bovine cells compared to a porcine isolate (1710S). -

Sera from 36 flocks of sheep and 20 flocks of goats were collected randomly. The results showed that 433 (21.8%) out of 1 984 ovine sera, and 82 (11.4%) out of 721 caprine sera, were seropositive for C. abortus infec- tion, as indicated by a titre ≥ 1:40. However, all the tested sheep flocks and goat flocks (100%) revealed at least one seropositive animal. There was a strong association (P < 0.05) between the rate of C. abortus infection and the size of the sheep flock, when larger flocks had higher infection rates. However, in goats, the flock size had no relation- ship with seropositivity. Age had no significant (P > 0.05) impact on C. abortus seropositivity. In sheep, there was a significant difference (P < 0.05) between the rates of the chlamydial infection in the four studied areas of northern Jordan. The highest infection rate in sheep (31.2%) was recorded in Mafraq area, while the rates in Irbid, Ajloun and Jerash were 18.5%, 11.2% and 13.9%, respectively. -
Plasmid-Cured Chlamydia Caviae Activates TLR2- Dependent Signaling and Retains Virulence in the Guinea Pig Model of Genital Tract Infection

The more genetically distant C. caviae GPIC is a natural pathogen of guinea pigs and induces upper genital tract pathology when inoculated intravaginally, modeling human disease. To examine the contribution of pCpGP1 to C. caviae pathogenesis, a cured derivative of GPIC, strain CC13, was derived and evaluated in vitro and in vivo. Transcriptional profiling of CC13 revealed only partial conservation of previously identified plasmid-responsive chromosomal loci (PRCL) in C. caviae. However, 2-deoxyglucose (2DG) treatment of GPIC and CC13 resulted in reduced transcription of all identified PRCL, including glgA, indicating the presence of a plasmid- independent glucose response in this species. In contrast to plasmid-cured C. -

Koala Immunogenetics and Chlamydial Strain Type Are More
www.nature.com/scientificreports OPEN Koala immunogenetics and chlamydial strain type are more directly involved in chlamydial disease progression in koalas from two south east Queensland koala populations than koala retrovirus subtypes Amy Robbins1,2, Jonathan Hanger2, Martina Jelocnik1, Bonnie L. Quigley1 & Peter Timms1* Chlamydial disease control is increasingly utilised as a management tool to stabilise declining koala populations, and yet we have a limited understanding of the factors that contribute to disease progression. To examine the impact of host and pathogen genetics, we selected two geographically separated south east Queensland koala populations, diferentially afected by chlamydial disease, and analysed koala major histocompatibility complex (MHC) genes, circulating strains of Chlamydia pecorum and koala retrovirus (KoRV) subtypes in longitudinally sampled, well-defned clinical groups. We found that koala immunogenetics and chlamydial genotypes difered between the populations. Disease progression was associated with specifc MHC alleles, and we identifed two putative susceptibility (DCb 03, DBb 04) and protective (DAb 10, UC 01:01) variants. Chlamydial genotypes belonging to both Multi-Locus Sequence Typing sequence type (ST) 69 and ompA genotype F were associated with disease progression, whereas ST 281 was associated with the absence of disease. We also detected diferent ompA genotypes, but not diferent STs, when long-term infections were monitored over time. By comparison, KoRV profles were not signifcantly associated with disease progression. These fndings suggest that chlamydial genotypes vary in pathogenicity and that koala immunogenetics and chlamydial strains are more directly involved in disease progression than KoRV subtypes. Chlamydial disease is a signifcant contributing factor afecting population viability in some declining northern Australian koala populations 1. -

Wilkins4,10,30, Peter Timms29,30 and Katherine Belov2,30,31 The koala, the only extant species of the marsupial family Phascolarctidae, is classified as ‘vulnerable’ due to habitat loss and widespread disease. We sequenced the koala genome, producing a complete and contiguous marsupial reference genome, including centromeres. We reveal that the koala’s ability to detoxify eucalypt foliage may be due to expansions within a cyto- chrome P450 gene family, and its ability to smell, taste and moderate ingestion of plant secondary metabolites may be due to expansions in the vomeronasal and taste receptors. -

FROM MANY CHLAMYDIAE TO ONE HEALTH Nicole Borel1 and Yvonne Pannekoek2 1Dept. of Pathobiology, Institute of Veterinary Pathology, Vetsuisse Faculty, University of Zurich, Zurich, Switzerland 2Dept. of Medical Microbiology, Academic Medical Center, Amsterdam, The Netherlands. Introduction The order Chlamydiales harbours members known for their relevance as human and animal pathogens. Until the 1990s it was thought that the Chlamydiaceae, represented as the only family of the order Chlamydiales, contained only one genus Chlamydia comprised of nine species. Research over the last 20 years, however, has resulted in the recognition and description or proposal of thirteen additionally families of genetically related organisms collectively referred to as ‘Chlamydia-related bacterias’ (CRBs)(1). New research has also revealed that expanded taxonomic diversity even exists within the well described genus Chlamydia (2-4). Many of the previously classified and newly described Chlamydiae are well recognized pathogens of humans and animals. While the zoonotic implications of many of these classified species is well known, recent research has uncovered new examples of their zoonotic potential either from existing known reservoirs or indeed new infection sources. Examples of this include the recent observation of zoonotic Chlamydia caviae presenting as severe community- acquired pneumonia (5) and the detection of Chlamydia suis in humans (6,7) exemplify the emergence of new risks and point to novel virulence properties for these microorganisms. Similarly the identification of novel Chlamydia abortus strains as zoonotic and abortive species in cattle and small ruminants (8) and the emerging role of Chlamydia psittaci in equine abortion (9), point both to the potential unrecognised impacts on animal health with significant potential for zoonotic risk.
