Wound healing, infection and the wound microbiome
Funded PhD Studentship to develop insects as models study wound healing, infection and the wound microbiome
The McCarthy Lab at Brunel University London is excited to offer a fully-funded PhD studentship to develop insects as models to study how wound infection impacts wound healing and survival prognosis. This studentship will use state of the art in vivo methodologies coupled with host-pathogen transcriptomics to identify key factors regulating wound infection progression.
Based in the College of Health, Medicine and Life Sciences, and funded by NC3Rs; the studentship offers an annual London rate stipend of £17,609 plus Home/EU tuition fees, for a maximum of 36 months. The start date is 1st of October 2021.
Almost all people at some point in their lives will experience a burn. Many of these burns are minor and can be remedied with a simple plaster to prevent infection. However, for individuals whose burns are large or deep enough to require a hospital visit, they run a higher risk of the burn wound becoming infected. In fact, infection is responsible for 75% of deaths among burn patients. This exceptionally high mortality rate has meant studying burn wound infection is a top priority. However, due to the physiological complexity of a burn wound, wound healing and infection cannot be adequately studied in vitro. Our previous work has developed for the first time an invertebrate model of burn wound trauma and concomitant infection using the greater wax moth larvae, Galleria mellonella. We have demonstrated that the G. mellonella burn wound model has remarkable similarities with mammalian burn wound models with key paradigms such as the role of fluid resuscitation in survival, and the link between percentage burn surface area and survival prognosis being conserved. We have also demonstrated that these larval burn wounds can be infected topically by leading burn wound pathogens such as Pseudomonas aeruginosa or Acinetobacter baumannii, replicating the mode of infection seen in the hospital environment. Our work has also shown that the infection progression cycle matches what is seen in human cases, with biofilm formation, local tissue necrosis, dissemination from the burn wound site, and ultimately mortality.
The prospective PhD student will develop this model of infection further to gain insights into the temporal kinetics underpinning bacterial colonisation of the burn site. They will also use RNA-Seq to explore the host/pathogen transcriptional response to burn trauma and infection. The prospective student will also have the opportunity to explore the role of the skin microbiome in promoting wound healing and preventing infection and demonstrate how this model can be used as an alternative to mammalian models to study the wound microbiome.
The successful candidate will be supervised by Dr Ronan McCarthy. For informal discussions about this studentship, please contact Dr Ronan McCarthy (email@example.com).
Candidates should have an undergraduate degree (first or upper second class) or equivalent qualification in Biosciences/Microbiology. A Masters qualification in a relevant area would be desirable. Experience in RNA-Seq analysis desirable. Applicants who have not been awarded a degree by a University in the UK will be expected to demonstrate English language skills to IELTS 7.0 (minimum 6.0 in any section).
