Therefore, Hominick and Reid (1990) proposed the use of
invasion efficiency (measured as the slope resulting from the linear regression of the number of established nematodes against the dose) as a direct measure of nematode infectivity.
As shown in Figure 4C and D, cells in the control groups exhibited approximately 3 times higher
invasion efficiency than cells in the urolithin A (UroA100) group, indicating that urolithin A could suppress cell invasion in vitro.
The
invasion efficiency of Campylobacter species pretreated with NA was analysed using a gentamicin protection assay.
Throat and/or skin isolates exhibiting highest
invasion efficiency than blood isolates have been reported (28), however, GAS from invasive and non invasive diseases adhered to and penetrated equally well into HEp-2 cells (29).
