New Group Member: Rebeca Pallarés Vega

We are very happy to welcome Rebeca Pallarés Vega (Palencia, Spain) who has joined the GrahAM research group as a Research Assistant to study the dynamics of plasmid transfer in Indian rivers on our AMRflows project. Rebeca studied a BSc in Biology at the University of Salamanca (Spain) and then to pursued an MSc in Advances and Research in Microbiology at the University of Granada (Spain). During her MSc, Rebeca did an internship in 2015 at the water research centre, Wetsus, in Leeuwarden, The Netherlands. This was when she became acquainted with antimicrobial resistance, and during her nine-month project, she studied resistant genetic profiles of bacteria isolated from hospital wastewater.

After completing her internship, Rebeca was granted a PhD position at TU Delft and Wetsus in collaboration with industrial stakeholders and water authorities. During her PhD, Rebeca focused on evaluating the presence and removal of antimicrobial resistance genes (ARGs) in wastewater and biosolids. Her main goal was to identify the role of wastewater system design, operational parameters, and abiotic factors (i.e., rainfall) on ARG removal dynamics. Rebeca also studied different conditions that might influence the spread of ARGs through the conjugal transfer of plasmids using in vitro and in situ experimental set-ups at the University of Copenhagen with the group of Professor Søren Sørensen.

In 2020, Rebeca joined the EU2020 project REPARES on behalf of Wetsus. There, she worked in method standardization and transfer across the consortium partners. We are very happy for Rebeca to join our group because her background fits perfectly into AMRflows, but our other work, such as wastewater-based epidemiology.

Faecal pollution promotes the environmental spread of AMR in Central Thailand

We want to strongly commend the manuscript Environmental antimicrobial resistance is associated with faecal pollution in Central Thailand’s coastal aquaculture region recently released in the Journal of Hazardous Materials. It is from a very interesting project led by Professor David Werner, Newcastle University, which studied the main drivers of environmental AMR spread in Central Thailand using HT-qPCR and MinION NGS. The work was in collaboration with partners at King Mongkut’s University of Technology Thonburi in Thailand and the Institute of Urban Environment of the Chinese Academy of Sciences.

The Graham Group contributed to the analysis and interpretation of AR gene data on the aquaculture ponds and local rivers, which corroborated that polluted rivers were contaminating the ponds, not the other way around. See more about on the clean water research being done by Professor Werner’s team on their blog. Additionally, see the Newcastle University’s press release about the work here.

Upcoming Talk on “AMR in wastewater – determinants and removal”

Prof David W Graham will be giving a public talk on AMR prevalence and monitoring in wastewater systems on 25 March 2021 is part the Wetsus REPARES network, supported by STOWA in the theme source separated sanitation. The Webinar starts at 15:30 (Netherlands) / 14:30 (UK) time and last about 90 minutes. This webinar is called “AMR in wastewater – determinants and removal” has three invited speakers, including David Graham, Dr Maarten Nederlof, and Rebeca Pallares Vega (soon to join our group in Newcastle). Drs Heike Schmitt and Lucia Hernandez will host the webinar. Talks are available online here.
