Crystal violet assay: Considering that most of AMPs isolated from Phyllomedusinae frogs act at the plasma membrane (Wan et al., 2015), the crystal violet assay was chosen as an initial screening test to assess any level of disturbance in the bacterial cell envelope permeability caused by the cutaneous secretion components (Devi, Nisha, Sakthivel, & Pandian, 2010).
Subsequently, Congo red and crystal violet dyes were applied; and it was observed under the polarized light that areas with amorphous matter accumulation rendered 'apple green reflections with Congo red (Figure 4).
Morphological characterization of bacterial isolates was done using staining techniques (i.e., simple staining using crystal violet, gram Staining, spore staining and capsule staining) following same procedures as described previously in manual (Cappuccino and Sherman, 2002).
Four passages (around 25 days) later, cells were fixed and stained with crystal violet (Figure 1(a)).
In addition, with positive CD3: immunohistochemical markers for reactive T lymphocytes, CD20: for reactive B lymphocytes, and CD38: for plasma cells and kappa and lambda positivity, similar areas of nodular formation were found with amyloid deposition using special staining for crystal violet (Figure 5) and Congo red (Figure 6).
Biofilm formation was measured in 96-well polystyrene microtiter plates (Costar, USA), following 24h of incubation at 35 [degrees]C, and staining with crystal violet as previously described by Stepanovic et al.
Importantly, this real-time biofilm disruption data correlated well with the data from traditional end point assays such as the labor intensive crystal violet staining technique.
