Objective: To explore whether the presence of Chlamydia trachomatis antibodies is associated with the severity of neoplastic lesions in women with cervical dyskaryosis.
Methods: In a cross sectional study in two groups of women referred for an abnormal Papanicolaou smear (group A: 296, group B: 331 women) blood samples were analysed for antichlamydial antibodies by enzyme immunoassay. Cervical neoplasia was graded histologically.
Results: In group A no association was found between increasing grade of CIN and the presence of antichlamydial antibodies. The proportion (93%) of women with antichlamydial antibodies was higher in 14 women with (micro)invasive carcinoma than in women with CIN (35%). As the high prevalence of antichlamydial antibodies in women with cervical carcinoma is not consistent with prevalences reported in recent literature, we analysed a second group of women in which indeed the high prevalence was not confirmed
Conclusion: Our results suggest that the presence of circulating antichlamydial antibodies is not associated with the severity of neoplastic lesions and it seems unlikely that C trachomatis has a role in the progression of cervical neoplasia.

Introduction: This study employs bulk RNA sequencing, PCR, and ELISA assays to analyze the pathological factors affecting the outcomes of ocular infections in koalas. It investigates the immune responses and gene expression profiles associated with various stages of koala ocular chlamydiosis.
Methods: A cohort of 114 koalas from Queensland, Australia were assessed, with 47% displaying clinical signs of ocular disease.

Background: There is evident inter-individual variability in women's responses to Chlamydial infections and reproductive tract problems. Women's genetic variations within the Interleukin-10 (IL-10) gene have been linked to variances in response to infection. This study was aimed to demonstrate the profound association of IL-10 with infertility and demonstrate the role of IL-10 (-592 C/A rs1800872) and (-1082 A>G rs1800896) single nucleotide polymorphism (SNPs) gene in the susceptibility and severity of a infection.

Aim - to identify deviations in immune parameters in patients with reactive chlamydial spondyloarthritis, allowing more targeted correction of immune status and improve the quality of treatment of these patients. A comparative immunological examination of 14 patients with reactive spondyloarthritis of chlamydial etiology before and after specific treatment and practically healthy people was carried out.
