Objective: In this study, the survival and recovery of Chlamydia pneumoniae (Cp) strains TW‐183, AR‐39, AR‐388 and CWL‐029 were measured after inoculation on glass, stainless steel, FormicaR laminate, paper, fabric and human skin. Methods: Inoculum in throat washes from healthy volunteers was applied to each surface. Samples were taken immediately after inoculum application and at specified intervals thereafter to determine infectivity. Results: Infectious Cp was recovered from glass for up to 4 h, from paper and fabric for up to 3 h, from FormicaR laminate for up to 2 h, from stainless steel for up to 60 min and from human skin for up to 30 min. Drying of the inoculated area had no significant effect on the recovery of infectious Cp. Further experiments demonstrated that infectious Cp could be transferred to hands by touching these contaminated surfaces and could be recovered from these hands for up to 3 min. Addition of albumin, surfactant or phosphatidylcholine had no significant effect on the survival of Cp. Conclusions: These results suggest that contact with contaminated surfaces may be a potential mode of transmission of Cp. 1995 European Society of Clinical Microbiology and Infectious Diseases
