NewsA two-pronged vaccine approach to prevent genital herpes
Researchers have taken a significant step toward a genital herpes vaccine that in preclinical models prevented infection. This study extends the original “prime and pull” approach by developing a new nanoparticle that effectively induces local immunity.

NewsMachine-learning how to overcome antibiotic-resistant gonorrhea
An AI-enabled antibiotic discovery proves effective at identifying new chemical structures and targets in the constant fight against antibiotic-resistant gonorrhea.

NewsResearcher secures nearly $4 million NIH grant to advance therapeutic vaccine to help end genital herpes
University of California, Irvine immunologist Lbachir BenMohamed has been awarded a $3.93 million National Institutes of Health grant to develop and test a novel therapeutic vaccine designed to prevent recurrent genital herpes.

NewsStudy finds common infection does not increase risk of recurrent preterm birth
A new study has found that the common sexually transmitted infection, Mycoplasma genitalium, also known as MGen, does not appear to increase the risk of recurrent preterm birth. Earlier research suggested that certain Mycoplasma species might contribute to preterm labor, but those studies were limited.

NewsSeven European countries observe drop in chlamydia notifications especially among young people in 2024
After a decade of general increases in chlamydia cases across Europe, the first signs of a decline suggest a possible common driver. Is it a true reduction and will it be a sustainable one?

NewsSurvey highlights persistent uncertainty on STI vaccines
A nationally representative survey of empaneled adults finds that while most Americans understand how STIs spread, there are significant gaps in public knowledge about which infections can be prevented through vaccination.

NewsBacterial STIs reach record highs in Europe, and congenital syphilis cases nearly double
New figures indicate a surge in bacterial sexually transmitted infections (STIs) across Europe. In 2024, notifications of gonorrhoea and syphilis, alongside congenital syphilis, reached their highest levels in over a decade, reflecting sustained transmission across multiple countries.

NewsOne-fifth of pregnant women aren’t properly screened for syphilis
A new study found that 1 in 5 pregnant women in Ontario did not receive timely syphilis screening, which is critical for preventing syphilis infection in newborns. Sociodemographic and behavioural risk factors associated with being screened late may be related to an increased likelihood of inadequate prenatal care access.

NewsParaprobiotic counteracts damage to male fertility from BPA in plastic
BPA has been shown to impair sperm function, in part through increased generation of reactive oxygen species. Researchers investigated whether a paraprobiotic material derived from the lactic acid bacterium Enterococcus faecalis (known as FK‑23) protects against the sperm toxicity caused by BPA.

NewsMpox study reveals hidden infections may fuel spread
A study shows that in mid- to late 2024, mpox was far more common among men who have sex with men than previously thought. Individuals without symptoms accounted for most infections and likely played a prominent role in transmission, contrary to prior assumptions that people had to be symptomatic to spread the disease.

NewsMass mating event reveals how yeast find the perfect match
When choosing mates, yeast organisms tend to pick partners that may increase the chances of their offspring’s success, according to a new study which revealed a link between the success of the parents and the genetic distance between them, and the success of their offspring.

NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsAs syphilis cases rise, study links infection with higher risk of stroke, heart attack and other serious cardiovascular problems
Adults with later-stage syphilis are more likely to develop major cardiovascular problems – including stroke, heart attack or aortic aneurysm – than similar patients without the infection. The increased risk is primarily found in those whose infection progressed longer than a year.

NewsHPV vaccination uptake in adults shaped by knowledge and medical advice
A nationwide survey of HPV uptake in Switzerland found just over 27% of the approximately 3,850 adults aged 18 to 45 surveyed had received at least one dose of the vaccine. While nearly 59% of those aged 18 to 26 are vaccinated, the rate drops to around 16% among those aged 27 to 45.

NewsHow periodontitis-linked bacteria accelerate osteoporosis-like bone loss through the gut
Researchers reveal that salivary bacteria from gum disease alter gut metabolism, driving osteoclast activity and systemic bone loss. They analyzed salivary microbiota from individuals with advanced periodontitis and compared them with samples from periodontally healthy donors.

NewsTestosterone increases severity of bacterial skin infections
Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study is the first to reveal testosterone, present at higher levels in males, as a key driver of infection.

NewsFecal transplants from older mice significantly improve ovarian function and fertility in younger mice
A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome of the gut and ovarian health and function.

NewsAkkermansia muciniphila PROBIO therapy promotes arginine biosynthesis and reverses reproductive impairments in polycystic ovary syndrome rats
A research study investigated the therapeutic potential of Akkermansia muciniphila PROBIO (AP) in a dehydroepiandrosterone-induced PCOS rat model, revealing significant improvements in reproductive and metabolic parameters through modulation of gut microbiota and enhancement of arginine biosynthesis.

NewsHPV vaccination provides “sustained protection” against cervical cancer
Human papillomavirus (HPV) vaccination is associated with a significantly reduced risk of invasive cervical cancer, with no indication of waning protection up to 18 years after vaccination, finds a study.

NewsMeningococcal B vaccination does not reduce gonorrhoea, trial results show
Contrary to existing evidence from observational studies, the meningococcal B vaccine (4CMenB) has no effect on preventing the acquisition of gonorrhoea, according to the results of the world’s largest randomised control trial (RCT) into possible efficacy.
