Fig. 3. Phylogenetic tree (Neighbour-joining) of the C. carrionii complex based on EF1 (with grouping I–III) using the same strains of Fig. 1, generated using the HKY+G model.<br />
<strong>The</strong> model was calculated using ML in MrAic software. Bootstrap cut-off = 80 %. <strong>CBS</strong> 834.96 was taken as outgroup. Columns were generated with Structure software<br />
hypothesising K = 4 <strong>and</strong> K = 5, <strong>and</strong> alleles independent. Geographical origins in black refer to isolates from humans (chromoblastomycosis); origins in green refer to isolates<br />
from plant material.<br />
inoculation, <strong>and</strong> from the thorns directly adjacent to this area.<br />
Samples were rinsed with 4 % sodium hypochlorite for 3 min, <strong>and</strong><br />
subsequently washed in sterile distilled water for re-isolations, <strong>and</strong><br />
for histological study by means of light microscopy (Fernández-<br />
Zeppenfeldt et al. 1994).<br />
Experiments with spines of S. griseus<br />
Ninety cactus spines of 2.5 cm av. length were collected from<br />
a single S. griseus plant located near the home of the patient<br />
infected with <strong>CBS</strong> 114402, at approx. 2.5 m height, superficially<br />
sterilised, <strong>and</strong> divided into three groups, of which 30 spines were<br />
inoculated with <strong>CBS</strong> 114402 (C. carrionii), 30 with <strong>CBS</strong> 114405<br />
(Cladophialophora sp.) <strong>and</strong> 30 to be used as control, inoculated<br />
with a saline solution (Fig. 1D). A <strong>similar</strong> series composed of 90<br />
spines of 1.5 cm average length was collected at approx. 1 m<br />
height. All spines were incubated in sterile Petri dishes with filter<br />
paper (Whatman #1) with 2 mL saline solution; subsequently 0.1<br />
mL fungal suspension was applied. Twenty spines were analysed<br />
weekly by means of longitudinal sectioning with a h<strong>and</strong>-held<br />
microtome, cultured as above <strong>and</strong> observed microscopically until<br />
day 75 post incubation.<br />
