Chlamydia trachomatis, C. pneumoniae, and C. psittaci, the three Chlamydia species known to cause human disease, have been collectively linked to several pathologies, including conjunctivitis, trachoma, respiratory disease, acute and chronic urogenital infections and their complications, and psittacosis. In vitro, animal, and human studies also established additional correlations, such as between C. pneumoniae and atherosclerosis and between C. trachomatis and ovarian cancer. As part of their survival and pathogenesis strategies as obligate intracellular bacteria, Chlamydia spp. modulate all three major types of epigenetic changes, which include deoxyribonucleic acid (DNA) methylation, histone post-translational modifications, and microRNA-mediated gene silencing. Some of these epigenetic changes may be implicated in key aspects of pathogenesis, such as the ability of the Chlamydia spp. to induce epithelial-to-mesenchymal transition, interfere with DNA damage repair, suppress cholesterol efflux from infected macrophages, act as a co-factor in human papillomavirus (HPV)-mediated cervical cancer, prevent apoptosis, and preserve the integrity of mitochondrial networks in infected host cells. A better understanding of the individual and collective contribution of epigenetic changes to pathogenesis will enhance our knowledge about the biology of Chlamydia spp. and facilitate the development of novel therapies and biomarkers. Pathogenic Chlamydia spp. contribute to epigenetically-mediated gene expression changes in host cells by multiple mechanisms.

Infectious keratoconjunctivitis is an infectious disease that negatively affects animal welfare causing systemic or local clinical signs in small ruminants and causes significant economic losses in herds. It is important to determine the etiologic agent causing the infection in the development of the protection and control strategies against the disease. The aim of this study was to determine the presence of infectious keratoconjunctivitis cases in small ruminants raised in Siirt province in Türkiye.

This study examines the distribution of microbial communities and antibiotic resistance genes (ARGs) across various vectors in poultry farm environments. The results show that airborne particulate matter (PM) and soil harbor the highest counts of microbial genes, exceeding those found in poultry visceral samples, which display lower microbial diversity and ARG levels. This highlights environmental vectors, particularly soil and PM, as major reservoirs for ARGs.

The obligate intracellular bacterial pathogen, (Ct), has a distinct DNA topoisomerase I (TopA) with a C-terminal domain (CTD) homologous to eukaryotic SWIB domains. Despite the lack of sequence similarity at the CTDs between TopA (CtTopA) and TopA (EcTopA), full-length CtTopA removed negative DNA supercoils and complemented the growth defect of an mutant. We demonstrated that CtTopA is less processive in DNA relaxation than EcTopA in dose-response and time course studies.

Molecular survey for Chlamydia among southern greater gliders (Petauroides volans) from southeastern New South Wales, Australia.

Southern greater gliders (Petauroides volans) are endangered Australian marsupials for which there is little health data currently available. Chlamydia pecorum is the only reported pathogen of greater gliders and infects a broad range of hosts, including other marsupials, ruminants, swine and birds. Conjunctival and cloacal swabs collected from thirty-two southern greater gliders across southeastern New South Wales, Australia were screened for Chlamydia spp.
