The #WHO #Bacterial Priority #Pathogens #List 2024: a prioritisation study to guide research, development, and public health strategies against antimicrobial resistance, https://etidiohnew.blogspot.com/2025/04/the-who-bacterial-priority-pathogens.html

In forests of Yunnan Province, China, bacterial diversity decreases with latitude, but ecosystem functioning relies more on common microbes than rare ones, highlighting the key role of community composition.

Water Quality and AMR 💧🦠

The effects of climate change on water systems are multifaceted:

• Increased #runoff and #flooding contribute to the dissemination of #contaminants.

• Alterations in #aquatic #ecosystems may favour the proliferation of specific #bacterial populations.

• #Wastewater treatment facilities encounter significant challenges.

• #Microplastics may function as #vectors for the transmission of #AMR #genes.

Environmental Changes 🌡️🦠

The rise in temperatures and alterations in precipitation patterns are leading to several significant consequences:

• Accelerated #bacterial growth rates

• Extended survival of #pathogens in the #environment

• Changes in the geographical #distribution of #diseases

• Altered effectiveness of #antimicrobials
