Tongue biofilm areal density and tongue coating index (2008)
Journal Article
Saad, S., & Greenman, J. (2008). Tongue biofilm areal density and tongue coating index. Journal of Breath Research, 2(1), https://doi.org/10.1088/1752-7155/2/1/017008

Two methods have been employed to measure the amount of tongue biofilm in humans: (1) areal density of microbes (cfu cm-2) (tongue scrape from a known/measured area), or (2) a tongue-coating index, where a human judge assesses the amount of 'coating'...

Modelling oral malodour from a tongue biofilm (2008)
Journal Article
Hess, J., Greenman, J., & Duffield, J. (2008). Modelling oral malodour from a tongue biofilm. Journal of Breath Research, 2(1), 017003. https://doi.org/10.1088/1752-7155/2/1/017003

A new model about the genesis of malodour emanating from the tongue is introduced. A new approach uses mathematical formulae to combine existing empirical knowledge and bring it into context. The resulting description of halitosis includes the three-... Read More about Modelling oral malodour from a tongue biofilm.

Aims: To develop a perfusion biofilm system to model tongue biofilm microflora and their physiological response to sulfur-containing substrates (S-substrates) in terms of volatile sulfide compound (VSC) production. Methods and Results: Tongue-scrape... Read More about In vitro biofilm model for studying tongue flora and malodour.

Use of a bioluminescent Pseudomonas aeruginosa strain within an in vitro microbiological system, as a model of wound infection, to assess the antimicrobial efficacy of wound dressings by monitoring light production (2007)
Journal Article
Thorn, R., Nelson, S., & Greenman, J. (2007). Use of a bioluminescent Pseudomonas aeruginosa strain within an in vitro microbiological system, as a model of wound infection, to assess the antimicrobial efficacy of wound dressings by monitoring light production. Antimicrobial Agents and Chemotherapy, 51(9), 3217-3224. https://doi.org/10.1128/AAC.00302-07

A bioluminescent Pseudomonas aeruginosa was incorporated into an in vitro static diffusion method to determine whether light output could be used as a measure of wound dressing efficacy. A significant linear correlation was observed between viable co...
