Interleukin-6-deficient (IL-6(-/-)) knockout mice had significantly increased Chlamydia trachomatis levels in lung tissue and increased mortality compared to B6129F2/J controls early after intranasal infection. Gamma interferon production and chlamydia-specific antibody levels were consistent with a decreased but reversible Th1-like response in IL-6(-/-) mice. IL-6 is needed for an optimal early host response to this infection.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection typically caused by serovars L1-L3 of . These serovars are tissue-invasive with a preponderance for lymphatic spread and can be acquired via unprotected oral, anal, or vaginal sex. We present the case of a 23-year-old with a prior history of syphilis admitted with four weeks of progressively enlarging painful right cervical lymphadenopathy.

Introduction: Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.

Exploring Bidirectional Causal Relationships between Antibody-Mediated Immune Responses to Infectious Agents and Systemic Lupus Erythematosus through Mendelian Randomization and Meta-Analyses.

Background: Previous investigations into the causal relationship between infections and systemic lupus erythematosus (SLE) have yielded controversial results. This study delves into the bidirectional causal relationships between various infectious agents and SLE, employing two-sample Mendelian randomization (MR) from an immunological perspective.

Methods: Utilizing genome-wide association study (GWAS) data for 46 antibody-mediated immune responses (AMIRs) to 13 pathogens and three distinct SLE datasets, we employed Bayesian Weighted MR (BWMR) and inverse variance weighted (IVW) methods to ascertain causal links, supplemented by meta-analysis to resolve inconsistencies.

Studies in humans indicate that certain serovars are more pathogenic than others. Specifically, several studies concluded that serovars from the C-complex are more pathogenic than those from the B-complex, although there are reports that do not support this finding. To investigate these results in an animal model, the eight genitourinary serovars were tested in two strains of mice: C3H/HeN and BALB/c.

Purpose Of Review: Antimicrobial resistance in sexually transmitted infections (STIs) has become an urgent global public health threat, raising the specter of untreatable infections. This review summarizes the determinants of resistance among the five most common curable STIs Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Treponema pallidum, and Trichomonas vaginalis, as well as strategies to mitigate the spread of resistance.

Recent Findings: Genetic mutations are key drivers of resistance for N.
