Pseudomonas

Question
Dear Expert team!

If a drop of water contains Pseudomonas aeruginosa, is it possible that the bacterium survives if the drop dries out?
Answer
Dear questioner,

Pseudomonas aeruginosa dies more or less rapidly when the drop dries out. It depends on light, temperature and the specific bacterial strain. I recommend the following literature:

1. Döring G, Ulrich M, Müller W, Bitzer J, Schmidt-Koenig L, Münst L, Grupp H, Wolz C, Stern M, Botzenhart K. Generation of Pseudomonas aeruginosa aerosols during hand¬washing from contaminated sink drains, transmission to hands of hospital person¬nel, and its prevention by use of a new heating device. Zbl Hyg 1991;191:494-505.

2. Döring G, Jansen S, Noll J, Grupp H, Frank F, Botzenhart K, Magdorf K, Wahn U. Distribution and transmission of Pseudomonas aeruginosa and Burkholderia cepacia in a hospital ward. Pediatr Pulmonol 1996;21: 90-100.

Sincerely yours,


Prof. Dr. Gerd Döring
