Sulfonamide resistance gene sul4 is hosted by common wastewater sludge bacteria and found in various newly described contexts and hosts | Microbiology Spectrum Antibiotic resistance is an ancient phenomenon and a common trait of many environmental bacteria. However, human activities in the post-antibiotic era, coupled with the bacteria’s ability to exchange ...

Our latest article examines the sulfonamide resistance gene sul4. By using long-read metagenomics and methylation patterns, we show that sul4 appears in diverse genetic contexts and hosts, expanding our understanding of its environmental distribution.

Temporal dynamics and microbial interactions shaping the gut resistome in early infancy Nature Communications - Here the authors show that antibiotic resistance genes peak in the gut at the age of 6 months, and that beneficial bifidobacteria produce aromatic lactic acids that actively...

Nice paper on the temporal dynamics of early infancy. Once again, it was shown that Escherichia & Klebsiella correlate with higher ARG load, and their abundance is in turn negatively associated with Bifidos. Kudos to the authors for the excellent paper!

Proud of our group's newest publication!

Great thread from @antagomir.bsky.social about our latest collaborative study led by the brilliant @katammp.bsky.social on the antibiotic resistome in a representative Finnish population of n>6,500 individuals and factors associated with carriage.

We look at the risks and sociodemographic aspects of antimicrobial resistance, and its association with recent global urbanization and middle-class growth.

Thank you #ASMicrobe 2025 for an excellent conference in Los Angeles! It was great to meet new people and present our team's recent work with #AMR

International comparison reveals gender differences in antimicrobial resistance A recent study led by the University of Turku, Finland, analysed the DNA map of more than 14,000 gut metagenomes in a global dataset and found that there are differences in antibiotic resistance be

International comparison reveals gender differences in antimicrobial resistance - an analysis of more than 14,000 open gut metagenomes indicates that in high-income countries women had more antibiotic resistance than men www.utu.fi/en/news/pres... /w @katammp.bsky.social @mahkamehsalehi.bsky.social

Hi! One of the lead authors here. We think it is mostly because women have more antibiotics than men on average, but also other things like profession (nursing, teaching small children), as well as behaviours, are likely to contribute. We're planning to do more research on this later.

🦠🌍 Antibiotic resistance differs by gender

A global study of 14,000+ gut samples found women in high-income countries have 9% more antibiotic resistance genes than men.

In lower-income countries, patterns flip – but context matters.

Take home message! Recognizing gender and age-specific differences in AMR is essential for research and for creating fair healthcare strategies. For more details, data, and code, read the full study with @katammp.bsky.social et al. here: www.nature.com/articles/s41...

Age and geography were significant factors associated with resistome composition, with infants and the elderly showing higher ARG loads and diversity. This pattern underscores the impact of life stages on AMR.

Genders share similar ARGs despite the difference in their abundance. Region and age explained far more variation in ARG composition than gender.

Gender differences in ARG abundance emerged in adulthood, indicating that gender-associated lifestyle, biological, or healthcare-related factors in adulthood may be linked to antibiotic resistance.

In LMICs, limited data indicated that when accounting for confounding factors such as age and socio-economics, the difference between men and women was not significant.

Women in HICs also showed slightly higher ARG diversity than men, suggesting a broader range of resistance genes present in their gut microbiomes.

In high-income countries (HICs), women had 9% higher ARG abundance compared to men. This suggests that women in HICs may be more exposed to or carry more antibiotic-resistant bacteria. In low-income countries (LMICs), the trend was reversed. www.nature.com/articles/s41...
