Personal profile

Prof Katie Laird is a Professor of Microbiology in the School of Pharmacy and Head of the Infectious Disease Research Group at De Montfort University. She has a BSc (Hons) in Biology and obtained a PhD in applied microbiology in 2008.

Her research is centred on the prevention of transmission of healthcare acquired infections including the development of novel antimicrobials. A particular focus of Prof Laird’s research is on the role of healthcare textiles as fomites, her research has raised international awareness of the risks to healthcare workers of incorrect laundering of uniforms. The research group she leads was the first to determine the stability of coronavirus on textiles during laundering; these findings informed global infection control policies in industrial laundries, thereby protecting laundry and healthcare workers. She has worked closely with world-leading brands and laundry trade bodies (UK, Europe and USA), securing significant funding to develop innovative and efficient approaches to combat the spread of pathogens via healthcare textiles. Prof Laird is currently developing an internationally-accepted test protocol which will transform the laundry industry globally through a united approach to validating

 She is also a founder of “A Germ's Journey” educational resources (www.germsjourney.com) teaching young children about health hygiene globally.

  • Stability of Human Coronavirus OC43 on Leather and Viral Transfer to Different Surfaces
    Stability of Human Coronavirus OC43 on Leather and Viral Transfer to Different Surfaces Shivkumar, Maitreyi; Adkin, Pat; Owen, Lucy; Patel, Jenish; Shantharamu, Usha; Goodyer, Larry; Laird, Katie Aims: This study aimed to investigate the stability of HCoV-OC43 on leather and transfer to other surfaces and to determine the antiviral activity of a silver-based leather coating. Methods and Results: The infectivity of HCoV-OC43 (6.6 log10 TCID50) on patent, nubuck, full-grain calf and corrected grain leathers (untreated and silver-coated) was measured over 72 hours by titration on BHK-21 cells. Recovery from pig skin (8-9 log10 TCID50) was also assessed. Transfer of infectious HCoV-OC43 from leather onto cardboard and stainless steel (0-48 hours post-inoculation) was quantified. HCoV-OC43 remained infectious for 6-48 hours on patent, finished and calf leathers; no infectious HCoV-OC43 was recovered from nubuck at 0 hours. Silver coating of full-grain calf and corrected grain leathers significantly reduced HCoV-OC43 infectivity (p≤0.05) after 2 hours, where no infectious virus was recovered. Transfer of HCoV-OC43 (≤3.1-5.5 log10) was detected from calf, finished and patent leather onto stainless steel and carboard up to 2 hours after inoculation, while no transfer was detected for silver-coated leathers at 2 hours. Leather has also been utilised as a skin surrogate for investigating fomite transmission. HCoV-OC43 was reduced by 4.71 log10 on pig skin at 0 hours, in a similar trend to highly absorbent nubuck leather. Conclusions: Human coronaviruses remain infectious on leather for up to 48 hours and transfer onto cardboard and stainless steel up to 2 hours post-inoculation. Absorbency contributes to the recovery/persistence of HCoV-OC43 on surfaces. A silver-based leather coating demonstrated antiviral activity and limited viral transfer onto other surfaces. Significance of Study: This investigation suggests that leather could pose a risk of indirect transmission of human coronaviruses; this is of significance for settings where there is close contact with leathers such as in manufacturing, retail and domestic environments. A silver-based leather coating demonstrated antiviral activity and limited viral transfer onto other surfaces, reducing the potential for indirect transmission from leathers.

  • Evaluation of Current Healthcare Laundry Hygiene Monitoring Methodologies
    Evaluation of Current Healthcare Laundry Hygiene Monitoring Methodologies Owen, Lucy; Laird, Katie Background Disease outbreaks in healthcare facilities (e.g., Bacillus cereus) have been linked to contaminated linen, highlighting the importance of decontamination of healthcare textiles and infection control measures to prevent recontamination. The COVID-19 pandemic has raised further concerns around textile hygiene. Methods for monitoring microbial kill during healthcare laundering and post-laundering contamination are not standardised across Europe, leading to potential variation in validation outputs. For example, EN14065 accreditation requires microbiological monitoring, however no standard method is prescribed. Microbial kill is commonly validated by laundering inoculated textiles. Post-laundering hygiene monitoring tests can be destructive (elution) or non-destructive (e.g., swabbing). This study aims to evaluate common methods for detection of microbial contamination on textiles and measuring kill during industrial laundering processes. Methods Recovery of Escherichia coli, Staphylococcus aureus, Enterococcus faecium or Bacillus cereus spores (108, 102 and 101 CFU/ml) from 100% cotton was evaluated using different elution buffers (phosphate buffered saline or maximum recovery diluent with and without polysorbate 80), agitation methods (vortexing, stomaching, shaking by hand or with glass beads) and recovery agar (selective or non-selective). Recovery was compared to swabbing, RODAC plates and dip slides. Survival of E. faecium during a cold industrial wash with and without detergent was compared between loose swatches and those enclosed within cloth bags. Results Recovery of all test species was significantly (p≤0.05) greater using elution methods than non-destructive methods, while RODAC plates and dip slides were unquantifiable at 108 CFU/ml. Recovery was not significantly different between elution buffers or recovery agar. Shaking by hand was generally marginally more precise and efficient in microbial recovery. E. faecium was significantly (p≤0.05) reduced by industrial laundering with and without detergent; there was no significant difference when enclosed in cloth bags. Conclusions Surface testing methods have limited sensitivity compared to elution methods, suggesting that destructive methods are most appropriate for hygiene monitoring of laundered healthcare textiles. Swatch testing is confounded by a loss of microorganisms to dilution and agitation in the wash; further tests need to be developed to monitor the kill of microorganisms in the wash in order to develop a standardised test methodology to be used throughout global industrial laundries.

  • Healthcare worker knowledge and attitudes towards uniform laundering during the COVID-19 pandemic
    Healthcare worker knowledge and attitudes towards uniform laundering during the COVID-19 pandemic Owen, Lucy; Apps, Lindsay; Stanulewicz, Natalia; Hall, Andrew; Laird, Katie Background: The COVID-19 pandemic raised concerns towards domestic laundering of healthcare worker (HCW) uniforms; this is common practice in countries such as the United Kingdom (UK) and United States. Previous research suggested 4-32% of nurses did not adhere to laundry policies, which could be an infection control risk. This study aimed to investigate the knowledge and attitudes of UK healthcare workers towards domestic laundering of uniforms during the COVID-19 pandemic. Methods: Online and paper questionnaires were distributed to HCWs and nursing students who regularly wear uniforms. Differences in knowledge between HCWs were analysed by Chi-squared tests and attitudes were examined using exploratory factor analysis. Results: 86% of participants (n=1099 of 1277) laundered their uniforms domestically. Respondents were confident in laundering their uniforms appropriately (71%), however 17% failed to launder at the recommended temperature (60°C). Most participants (68%) would prefer their employer launder their uniforms, with mixed negative emotions towards domestic laundering. Limited provision of uniforms and changing/storage facilities were a barrier to following guidelines. Conclusion: Most HCWs domestically launder their uniforms, despite a preference for professional laundering. One-fifth of HCWs deviated from the UK National Health Service uniform guidelines; onsite changing facilities were the most significant barrier towards adherence.

  • Antiviral plant-derived natural products to combat RNA viruses: Targets throughout the viral life cycle
    Antiviral plant-derived natural products to combat RNA viruses: Targets throughout the viral life cycle Owen, Lucy; Laird, Katie; Shivkumar, Maitreyi There is need for new effective antivirals, particularly in response to the development of antiviral drug resistance and emerging RNA viruses such as SARS-CoV-2. Plants are a significant source of structurally diverse bioactive compounds for drug discovery suggesting that plant-derived natural products could be developed as antiviral agents. This article reviews the antiviral activity of plant-derived natural products against RNA viruses, with a focus on compounds targeting specific stages of the viral life cycle. A range of plant extracts and compounds have been identified with antiviral activity, often against multiple virus families suggesting they may be useful as broad-spectrum antiviral agents. The antiviral mechanism of action of many of these phytochemicals is not fully understood and there are limited studies and clinical trials demonstrating their efficacy and toxicity in vivo. Further research is needed to evaluate the therapeutic potential of plant-derived natural products as antiviral agents. The file attached to this record is the author's final peer reviewed version.

  • Porous surfaces: stability and recovery of coronaviruses
    Porous surfaces: stability and recovery of coronaviruses Owen, Lucy; Shivkumar, Maitreyi; Cross, Richard Barrie Michael; Laird, Katie The role of indirect contact in the transmission of SARS-CoV-2 is not clear. SARS-CoV-2 persists on dry surfaces for hours to days; published studies have largely focused on hard surfaces with less research being conducted on different porous surfaces, such as textiles. Understanding the potential risks of indirect transmission of COVID-19 is useful for settings where there is close contact with textiles, including healthcare, manufacturing and retail environments. This article aims to review current research on porous surfaces in relation to their potential as fomites of coronaviruses compared to non-porous surfaces. Current methodologies for assessing the stability and recovery of coronaviruses from surfaces are also explored. Coronaviruses are often less stable on porous surfaces than non-porous surfaces, for example, SARS-CoV-2 persists for 0.5 h–5 days on paper and 3–21 days on plastic; however, stability is dependent on the type of surface. In particular, the surface properties of textiles differ widely depending on their construction, leading to variation in the stability of coronaviruses, with longer persistence on more hydrophobic materials such as polyester (1–3 days) compared to highly absorbent cotton (2 h–4 days). These findings should be considered where there is close contact with potentially contaminated textiles. open access article Owen, L., Shivkumar, M., Cross, R.B.M. and Laird, K.

  • Disinfection of laundry using low temperature validated ozone system, OTEX, against human coronavirus HCoV-OC43
    Disinfection of laundry using low temperature validated ozone system, OTEX, against human coronavirus HCoV-OC43 Owen, Lucy; Cripwell, Lucy; Hook, Jackie; Shivkumar, Maitreyi; Laird, Katie Introduction: The survival of the COVID-19 coronavirus (SARS-CoV-2) on textiles during laundering and in the presence of ozone is not well understood. In this study, the stability of a model human coronavirus (HCoV-OC43), on cotton textiles laundered using the OTEX validated ozone disinfection system was investigated. Method: Samples of cotton were contaminated with HCoV-OC43 and then washed using the Foul and Infected (40°C) cycle with laundry detergent and ozone. Sterile textile samples were washed in the same load to investigate potential cross contamination of HCoV-OC43. After washing, the number of infectious virus particles present on the cotton samples was determined. In a time-assay study, the stability of HCoV-OC43 in the presence of ozone over time was also investigated. Cotton samples contaminated with HCoV-OC43 were exposed to ozone in solution, for 3 and 6 minutes. The number of infectious virus particles remaining on the cotton after the wash was determined. For both the contamination tests and time-assay study, washes without detergent and ozone were included as controls. Results: No infectious virus was detected on contaminated cotton samples after washing using the OTEX Foul and Infected cycle, demonstrating at least 1.6 log10 reduction in HCoV-OC43 infectivity from the textile when using this wash cycle. No infectious virus was detected on sterile textile samples included in the washes, suggesting that there was no detectable cross-contamination occurring within the wash. In the time-assay study, HCoV-OC43 infectivity was reduced by at least 4.3 log10 within 6 minutes of washing in the presence of ozone – beyond that of the limit of detection. Discussion: These findings show that ozone contributes to the inactivation of HCoV-OC43. Overall, the results suggest that coronaviruses such as HCoV-OC43 are unlikely to persist within the OTEX laundering cycle. Owen, L., Cripwell, L., Hook, J., Shivkumar, M. and Laird, K.

  • Investigation of the stability and risks of fomite transmission of human coronavirus OC43 on leather
    Investigation of the stability and risks of fomite transmission of human coronavirus OC43 on leather Shivkumar, Maitreyi; Adkin, Pat; Owen, Lucy; Laird, Katie Limited research exists on the potential for leather to act as a fomite of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or endemic coronaviruses including human coronavirus (HCoV) OC43; this is important for settings such as the shoe manufacturing industry. Antiviral coating of leather hides could limit such risks. This study aimed to investigate the stability and transfer of HCoVOC43 on different leathers, as a surrogate for SARS-CoV-2, and assess the antiviral efficacy of a silver-based leather coating. The stability of HCoV-OC43 (6.6 log10) on patent, full-grain calf, corrected grain finished and nubuck leathers (silver additive-coated and uncoated) was measured by titration on BHK-21 cells. Transfer from leather to cardboard and stainless steel was determined. HCoV-OC43 was detectable for 6 h on patent, 24 h on finished leather and 48 h on calf leather; no infectious virus was recovered from nubuck. HCoV-OC43 transferred from patent, finished and calf leathers onto cardboard and stainless steel up to 2 h post-inoculation (≤3.1–5.5 log10), suggesting that leathers could act as fomites. Silver additive-coated calf and finished leathers were antiviral against HCoV-OC43, with no infectious virus recovered after 2 h and limited transfer to other surfaces. The silver additive could reduce potential indirect transmission of HCoV-OC43 from leather. open access article Shivkumar, M., Adkin, P., Owen, L., Laird, K.

  • A Germ’s Journey: co-creation of resources for addressing UN Sustainable Development Goals in education & health in low-and-middle-income countries
    A Germ’s Journey: co-creation of resources for addressing UN Sustainable Development Goals in education & health in low-and-middle-income countries Crosby, Sapphire; Laird, Katie; Younie, Sarah Following a Participatory Action Research (PAR) model, this study evaluates whether specifically developed resources (‘A Germ’s Journey’) aid children in India’s understanding of hand-hygiene principles. Furthermore, it discusses how the findings can inform the future development of culturally relevant resources for developing countries. Educational health-hygiene workshops were conducted with schools and community centres in collaboration with organisations in Ahmedabad, India in areas of considerable socio-economic disadvantage. Children’s and teacher-trainer workshops were delivered to ten Case Studies. Mixed-method data was collected from children using quasi-experimental methods, using pre-workshop questions, follow-up questions, observations and baseline and post-workshop assessments. Data was collected from teachers using questionnaires. Following teacher-trainer workshops during Phase 1 of the study, 100% of teachers stated that they would use the resources with their pupils in the future. Two months after participating in the workshops, 60-73% of children knew how germs can cause illness, and 76-80% knew how to remove germs from hands. When assessed during Phase 2 of the study, 54% of children scored higher after the intervention, showing an increased understanding of microbiology after using the resources. The results indicate that children have an improved understanding of the cause of bacterial disease and the health implications of not using adequate health-hygiene practices. Recommendations for the future development of resources include adopting a PAR model of research, co-creation with end users and working alongside local organisations and participants in order to access the ‘hard-to-reach’ areas.

  • The Global Impact of A Germ’s Journey: Interactive Learning Resources and Behavioural Training to Improve Young Children’s Knowledge of Microorganisms and Handwashing Skills Worldwide
    The Global Impact of A Germ’s Journey: Interactive Learning Resources and Behavioural Training to Improve Young Children’s Knowledge of Microorganisms and Handwashing Skills Worldwide Crosby, Sapphire; Laird, Katie; Younie, Sarah Interdisciplinary research between psychology, health sciences and education has resulted in the co-creation of ‘A Germ’s Journey’; a resource-based intervention comprising books, web games, videos and posters. The resources are utilised globally across Africa, Asia and Europe, with 3,540 books donated to schools, museum exhibits, community centres and refugee camps reaching 145,432 people thus far. Most recently, these resources have been developed in response to the Covid-19 pandemic in line with WHO guidelines stating that handwashing is the most effective strategy for prevention of infection. The A Germ’s Journey health-education intervention was developed to improve young children’s understanding of microorganism transfer and efficient handwashing techniques to tackle infection. This presentation outlines the findings from a collection of studies that evaluate whether specifically co-created resources (A Germ’s Journey) aid children’s understanding and practice, and teachers’ pedagogy of effective hand-hygiene in the UK and Low-and Middle-Income Countries. Educational health-hygiene workshops were conducted with schools in the UK and in Sierra Leone and India in areas of considerable socio-economic disadvantage. Mixed-method data was collected from children using quasi-experimental methods, using pre-workshop questions, follow-up questions, observations and baseline and post-workshop assessments. Data was collected from teachers using questionnaires and focus groups. Results from evaluative studies demonstrate that the use of A Germ’s Journey multi-component educational resources induce significant improvements in children’s knowledge of microorganisms and handwashing skills. For example: among one sample of UK schoolchildren, 20% more washed between their fingers one month after engaging with the learning resources, and 30% more linked handwashing to germs. The effect of the intervention also extends to reducing the cases of diarrhoea and vomiting related illness in India. Additionally teachers (100%) reported on the usefulness of the resources. A Germ’s Journey resources enhance children’s understanding of handwashing, microorganism transfer and disease development, thereby improving handwashing behaviour in children in both the UK and Low-and-Middle-Income Countries, addressing the UN Sustainable Development Goals for health (SDG3) and education (SDG4).
