| Description | To date, we have funded valuable exchanges visits leading to a successful BBSRC grant submission (BB/P02095X/1) involving our laboratories and now published two manuscripts: doi: 10.1128/AAC.02085-15 and doi: 10.1042/CS20200971. Through my visit to Argentina in 2016, I have now set up a additional collaboration in Argentina Dr Cataldi around cattle colonisation and vaccine research and have enabled some PacBio sequencing of their cattle isolates in collaboration with the USDA which is just being submitted for publication. Further research is now being planned with CONICET and we have recently been awarded workshop funding from BBSRC (BB/T019743/1) to extend the collocation with CONICET to help understand whether the high rates of infection they have in Argentina are linked to the genetics of their circulating strains. This workshop will be delayed until permissible due to the SARC-CoV2 pandemic. |

| Description | Argentina has some of the highest rates of kidney damage (HUS) due to E. coli O157 infection in the world. We have expertise in the UK in understanding this organism and why certain strains are more likely to be associated with serious human disease. The partnership award has led to information exchange around this important issue and has allowed us to include Argentinian isolates in current seqeuncing projects for comparative studies. We have submitted a collaborative grant to BBSRC to investigate differences in strain pathogenesis and this was awarded in 2017. This will allow us to further build the collaboration with CONICET. As a result of my visit to visit to CONICET in 2016, we had further collaborative visits in 2018 that overlapped with the 3-yearly VTEC international conference held in Florence in 2018. We have supported visits, one from Romina Brando to carry out further work in our laboratory to complete investigations of some highly pathogenic EHEC O157 strains and this has now been published. The other visit was from Angel Cataldi who works in cattle vaccine development and a relationship is being build there towards further research. We have been awarded international workshop funding to continue discussion of E. coli O157 issues and interventions in Argentina but this has been delayed until March 2023. |

| PI Contribution | Provision of animal and human STEC for sequencing, working with PHE to analyse strain phylogeny and epidemiology. We have contributed through further analysis of long read strain sequences to understand changes in strains that occur during outbreaks. We have co-upervised 2 PhD students on STEC bioinformatics projects. |
| Collaborator Contribution | Reduced rate sequencing of STEC, analysis of data, provision of metadata. Co-publication |

| PI Contribution | This award is a 'partnering award' and it has been successful in leading to research exchange trips and discussion between our laboratory and several groups in Argentina, primarily Dr Marina Palermo, CONICET, Buenos Aires and Dr Angel Cataldi, Instituto de Biotecnología, Hurlingham. We have provided genomics and gene expression expertise to aid their analysis of argentinian E. coli O157 isolates. |
| Collaborator Contribution | They have provided strains, immunological expertise and access to a mouse model to investigate Shiga toxin release and pathology |
| Impact | manuscript as presented in main section. The partnering award allows me to travel to Argentina, present our work and initiate discussions with Dr Angel Cataldi at an institute separate from Conicet. |
