  • This dataset contains information about the number of bacterial colonies recovered from plastics beads that were incubated in a 96-well plate for 24 hours at 37 degrees Celsius. Each well in the plate had 1 bead composed of polycaprolactone in it and 150 microlitres of Isopropyl β- d-1-thiogalactopyranoside (IPTG) induced bacterial cell culture. Three replicates were performed. The bacterial cells had been modified to harbour plasmids that encoded genes to trigger the cells to form biofilms, the expression of these genes was induced using IPTG. An empty plasmid was used as the control. The work was supported by the Natural Environment Research Council (Grant NE/X010902/1), as part of an experiment looking into using synthetic biology to manipulate bacterial social behaviours to maximise the microbial degradation of environmental waste plastics.

  • Antibiotic susceptibility tests are presented as the zone of inhibition using the disc-diffusion method, and categorized as resistant, intermediate or susceptible. DNA samples from antibiotic-resistant bacteria were analysed for the presence or absence of resistance genes using polymerase chain reaction (PCR). Laboratory analyses were conducted by trained staff at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). The aim of the study was to identify the antibiotic-susceptibility profiles and resistance genes of bacteria (Escherichia coli) obtained from humans, poultry and the environment. Bacterial isolates previously identified with resistance to third-generation cephalosporins or carbapenems were included in the analysis. Bacterial samples originated from rural households and poultry farms (broiler chickens) in Mirzapur, Tangail district; and urban food markets in Dhaka city, Bangladesh. Environmental samples included surface water, water supply, wastewater, soil, animal faeces (poultry and cattle) and solid waste. The survey was part of a wider research project, Spatial and Temporal Dynamics of Antimicrobial Resistance Transmission from the Outdoor Environment to Humans in Urban and Rural Bangladesh. The research was funded by NERC/BBSRC/MRC on behalf of the Antimicrobial Resistance Cross-Council Initiative award NE/N019555/1.

  • This resource holds survival data of human pathogens bound to microplastics during transfer through the freshwater-marine continuum. The survival of Escherichia coli, Enterococcus faecalis and Pseudomonas aeruginosa colonising polyethylene or glass particles was quantified in mesocosm incubation experiments designed to simulate, (1) the direct release of microplastics from wastewater treatment plants (WWTPs) into freshwater and seawater environments; and (2) the movement of microplastics downstream following discharge from the WWTP through the river-estuary-marine-beach continuum. Background bacterial concentrations and crystal violet were also measured. Full details about this nonGeographicDataset can be found at https://doi.org/10.5285/c31c0b2a-ee5b-479f-84c3-ff1b0bfc6d84
