Project description:An M307 G/A point mutation of FUT1 gene has been considered as a usful marker to select the piglets that are sensitive(GG/AG genotype) or resistant(AA) to Escherichia coli F18 in foreign pig breeds. However,it is not suitable to Chinese native breeds. Duodenal tissues were collected from 3 full-sib pairs of Sutai pigs (a new hybrid between the Duroc and Taihu breeds) at the age of 28-day differing in adhesion phenotype to find the differential miRNAs that can provide the basis for analyzing the different mechanisms of E.coli F18 resistance between foreign and Chinese native breeds,as well as for breeding for disease resistance in Chinese native breeds in the future.

Unfortunately, the sequencing of 2385 was a failure and was excluded. 2385 piglet has an AA genotype of the FUT1 gene

Project description:The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmids pAMNF (encoding an N-terminal MarR-3xFLAG fusion) or pAMNM (encoding an N-terminal MarR-8xmyc fusion). The cells was cultured at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using an anti-FLAG antibody (i.e. the strain encoding the MarR-8xmyc fusion was used as a control). Libraries were prepared using DNA remaining after immunoprecipitation.

Project description:The experiment contains ChIP-seq data for Enterotoxigenic Escherichia coli strain H10407 transformed with plasmid pRGM9818. The strain was grown at 37 degrees in LB medium and crosslinked with 1 % (v/v) formaldehyde. After sonication, to break open cells and fragment DNA, immunoprecipitations were done using antibodies against MarA, MarR or the RNA polymerase sigma 70 subunit. Libraries were prepared using DNA remaining after immunoprecipitation. Note that the MarR immunoprecipitations were not successful but the data served as a useful control for non-specifically immunoprecipitated DNA sequences.

Project description:Previous research has suggested that the adhesin encoded by the F18 fimbrial operon in Escherichia coli is either the FedE or FedF protein. In this work, we show that anti-FedF antibodies, unlike anti-FedE serum, were able to inhibit E. coli adhesion to porcine enterocytes. Moreover, specific adhesion to enterocytes was shown with purified FedF-maltose binding protein.

Project description:Post-weaning diarrhea and edema disease caused by F18 fimbriated E. coli are important diseases in newly weaned piglets and lead to severe production losses in farming industry. Protective treatments against these infections have thus far limited efficacy. In this study we generated nanobodies directed against the lectin domain of the F18 fimbrial adhesin FedF and showed in an in vitro adherence assay that four unique nanobodies inhibit the attachment of F18 fimbriated E. coli bacteria to piglet enterocytes. Crystallization of the FedF lectin domain with the most potent inhibitory nanobodies revealed their mechanism of action. These either competed with the binding of the blood group antigen receptor on the FedF surface or induced a conformational change in which the CDR3 region of the nanobody displaces the D″-E loop adjacent to the binding site. This D″-E loop was previously shown to be required for the interaction between F18 fimbriated bacteria and blood group antigen receptors in a membrane context. This work demonstrates the feasibility of inhibiting the attachment of fimbriated pathogens by employing nanobodies directed against the adhesin domain.
