The prevalence of chlamydial DNA determined by PCR and in-situ hybridisation (ISH) in fresh tissue specimens (endometrium, fallopian tube and ovary) was investigated in 33 women presenting with ectopic pregnancy (EP), 14 women with tubal factor infertility (TFI) and 50 control patients from the UK and the West Indies. In the UK EP group, chlamydial DNA was detected by PCR in 56% of patients; similar results were found in the Trinidad EP group (67%). In the TFI group, chlamydial DNA was detected in (71%) of patients by PCR. The detection of Chlamydia trachomatis DNA by ISH was highest in the TFI group (43%). Women presenting with EP and TFI showed evidence of previous or current genital C. trachomatis infection, underlining the importance of this microorganism in the development of these conditions. Importantly, chlamydial DNA could be detected in DNA preparations from the endometrium, fallopian tube and ovary of EP and TFI patients at the time of surgery.

Background: Sexually transmitted infections (STIs) rank among the most prevalent acute infectious conditions and remain a major global public health concern. Notable STI pathogens include Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), and Neisseria gonorrhoeae (NG). Early detection and diagnosis are crucial for controlling the spread of STIs.

Objectives: Chlamydia trachomatis is the most commonly diagnosed bacterial sexually transmitted infection (STI) worldwide. Diagnosis relies on nucleic acid amplification techniques, such as PCR, which does not distinguish between viable pathogens and residual bacterial DNA, leading to potential overdiagnosis and overtreatment. PCR with confirmation of pathogen viability has not been widely explored in the STI field.

Chlamydias are zoonotic pathogens, broadly present in several bird species and responsible for economic losses in animal production. Our study focused on assessing the prevalence of Chlamydial species posing zoonotic risks in farm animals within the highly biodiverse Argentine, Brazil, and Paraguay tri-border area, characterized by significant human interaction. We surveyed nine farms in an area and nasally swabbed a total of 62 animals, that included cattle, horses and pigs.

Characterising functional diversity is a vital element to understanding a species' immune function, yet many immunogenetic studies in non-model organisms tend to focus on only one or two gene families such as the major histocompatibility complex (MHC) or toll-like receptors (TLR). Another interesting component of the eukaryotic innate immune system is the antimicrobial peptides (AMPs). The two major groups of mammalian AMPs are cathelicidins and defensins, with the former having undergone species-specific expansions in marsupials.

Sexually transmitted proctitis, a prevalent concern among men who have sex with men (MSM) is frequently caused by a range of pathogens, including herpes simplex virus (HSV), and While HSV-associated proctitis typically presents with visible lesions, cases without external manifestations remain evasive. We report the case of an MSM in his early 30s presenting with dyschezia and perineal discomfort after unprotected anoreceptive intercourse. Despite initial inconspicuous findings, rectal swabs revealed HSV-2 infection.
