TL;DR: In this article, the authors investigated the impact of substituting 100mm Petri dishes with 90mm disposable Petri-dishes, and showed that the use of a modernized colony counter should be clearly regulated and permitted to avoid the counting of positive holes.

Deposition and clearance of inhaled particles.
TL;DR: Theoretical models of respiratory tract deposition of inhaled particles are compared to experimental studies of deposition patterns in humans and animals, as determined principally by particle size, density, respiratory rate and flow parameters.
Journal ArticleDOI
Legionellae in engineered systems and use of quantitative microbial risk assessment to predict exposure.
TL;DR: Understanding the conditions favouring Legionella occurrence in engineered systems and their overall ecology will aid in developing new treatment technologies and/or systems that minimize or eliminate human exposure to potentially pathogenic legionellae.

An in-premise model for Legionella exposure during showering events
TL;DR: An exposure model was constructed to predict the critical Legionella densities in an engineered water system that result in infection from inhalation of aerosols containing the pathogen while showering to help to identify critical conditions that might lead to infection derived from pathogens within the biofilms of any plumbing system.

A quantitative microbial risk assessment model for Legionnaires' disease: animal model selection and dose-response modeling.
TL;DR: In this article, the authors used the Cavia porcellus dose-response data for modeling human risk of Legionnaires' disease (LD) in guinea pigs and compared the results with those of the human risk.
