Ciliated epithelial cells from human nasal polyps were cultured and infected with C. trachomatis. The measurement of ciliary beating was based on a technique which enables one to monitor a fraction of a single ciliated cell. A marked decrease of ciliary beating frequency versus time was observed 24 h after infection with C. trachomatis. About 50% of the cilia of infected cells were paralysed 48 h post-infection. The potential effect of C. trachomatis infection on the physiological functions dependent on cilia is discussed., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-135-1-105
