Gentamicin invasion assay. Invasion rates of U. diversum strains 34, 37, 174, 72 and ATCC 49782 in Hep-2 cells after 24, 48 and 72 hours. The studied ureaplasmas presented a higher rate of invasion between 48 and 72 hours of infection. Comparison of infection rates among strains isolated from clinical sample and standard strain ATCC 49782 (Mann–Whitney test, p-value ≤ 0.05). No statistically significant differences were found between the clinical strains and the standard strain in the study. However, a trend was observed once since invasion rates were higher when time of infection was increasing.
