TB and HIV treatments are not enough for a full recovery - Texas Biomed Existing treatments for tuberculosis (TB) and HIV control the pathogens, but the immune system does not revert to normal, according to research by Texas

Existing treatments for #tuberculosis and HIV control the pathogens, but the immune system does not revert to normal

The preclinical findings help explain why people living with #HIV likely remain more susceptible to other illness and reinfection with #TB – and point to the need for new therapies

Intracellular competition shapes plasmid population dynamics From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Non-conjugative plasmids limit their mobility to persist in nature Sabnis et al. explain why non-conjugative plasmids move at a low rate in nature. While increased mobility can easily evolve by incorporating phage DNA into plasmids, this is disadvantageous because it...

Genomic resistance in historical clinical isolates increased in frequency and mobility after the age of antibiotics Antibiotic resistance is frequently observed shortly after the clinical introduction of an antibiotic. Whether and how frequently that resistance occurred before the introduction is harder to determin...

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years?

The social determinants of tuberculosis: a case-control study characterising pathways to equitable intervention in Peru - Infectious Diseases of Poverty Background Despite being key components of global tuberculosis policy, poverty reduction and social protection interventions have been inconsistently implemented. We aimed to characterise how poverty ...

The global TB epidemic is driven by social determinants. In this case-control study in Peru, we characterised the associations between multidimensional household poverty, personal risk factors, and TB. @tb-lshtm.bsky.social idpjournal.biomedcentral.com/articles/10....

Really pleased to see this study led by @raymondkiu.bsky.social now published in @natcomms.nature.com!
