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. doi.org/10.1128/spec... #AntibioticResistance

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! rdcu.be/eDRPa

Variation and prognostic potential of the gut antibiotic resistome in a population-based cohort www.nature.com/articles/s41... We look at the risks and sociodemographic aspects of antimicrobial resistance, and its association with recent global urbanization and middle-class growth.

🦠🌍 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. 🔗 www.nature.com/articles/s41... #SciComm #AMR 🧪

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...

Antimicrobial resistance #AMR is a major #globalhealth threat. How does it vary between genders? We analyzed 14,641 open human gut #metagenomes from 32 countries to investigate gender differences in #antibioticResistance genes (ARGs). www.nature.com/articles/s41...
