Variation in sediment and rhizosphere microbial communities of Posidonia oceanica across sites exposed to different human influences. (PubMed, Mar Environ Res) - "By contrast, bacterial communities in the P. oceanica rhizosphere did not vary among sites exposed to different human pressures and were enriched with Acidimicrobiia (i.e., Ilumatobacter fluminis and CADEDH01 sp902826025) in respect to surrounding sediments...However, an inability for root bacterial communities to adapt to changes in environmental conditions may render them vulnerable to increasing environmental stress. Testing these two contrasting hypotheses will be an important avenue for future research."

Extraintestinal pathogenic Escherichia coli (ExPEC) O-serotype distribution and antibiotic resistance profiles among the aging population in China: A longitudinal, multi-center study. (PubMed, Int J Antimicrob Agents) - "In conclusion, O25 is the most prevalent O serotype among ExPEC isolates. The ExPEC9V O-serotype prevalence is generally consistent across MDR and different sexes."

Population structure of Escherichia coli isolated from the human bloodstream, human and animal feces, and the environment in northern Tanzania. (PubMed, J Infect Dis) - "We found a high diversity of sequence types among E. coli human bloodstream isolates in Tanzania. Despite this diversity, we observed that an EXPEC9V in development would provide good coverage. Reservoir attribution studies at finer spatial and temporal scales may better identify transmission networks and reservoirs of ExPECs."

High diversity of Escherichia coli causing invasive disease in neonates in Malawi poses challenges for O-antigen based vaccine approach. (PubMed, Commun Med (Lond)) - "Vaccines against neonatal sepsis in Africa are of considerable potential value, but their development requires larger studies to establish the diversity and stability over time of relevant O-types for this population."
