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).
