<i>Paracoccidioides - Figure 1 </i> Species Complex: Ecology, Phylogeny, Sexual Reproduction, and Virulence

<p>(A) Median-joining haplotypic network distribution of the <i>Paracoccidioides</i> genus and <i>L. loboi</i> based on the <i>gp43</i> marker. The size of the circumference is proportional to the haplotype frequency, and colors vary according to the sampling location of each haplotype. Red dots (median vectors) are hypothetical missing intermediates, and black dots represent each mutation site. (B) Schematic representation of serum/antigen compatibility among patients and isolates from Mato Grosso and São Paulo used in serological tests. The illustration shows the low immunogenic specificity when serum and antigenic pool from different states are reacted <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1004397#ppat.1004397-Batista1" target="_blank">[41]</a>.</p

Environmental Mapping of <i>Paracoccidioides</i> spp. in Brazil Reveals New Clues into Genetic Diversity, Biogeography and Wild Host Association - Fig 3

<p><b>A)</b> Molecular Phylogenetic Analysis by of ITS locus revealed by Maximum Likelihood and Neighbor Joining methods, using the Jukes-Cantor model parameters with range correction. Replication percentages on the tree are grouped in the bootstrap test (1000 replicates) and shown next to the branches. The sequences related to environmental samples are identified by acronyms SO_GO (Soil of Goiás) and AR_GO (Aerosol Goiás), AR_MG (Aerosol Minas Gerais) and SO_RO (Soil of Rondônia). <b>B)</b> Median-joining network showing the unique haplotypes of the Soil Clades I and II. Circles are proportional to haplotype frequency and numbers of mutations are represented by black dots. Red circles represent hypothetical missing intermediates (median vectors).</p

Fungal structures (400X) visualized by FISH and TSA-FISH techniques for aerosol samples and controls.

<p><b>A:</b> aerosol samples from Goiás with DAPI. <b>B:</b> aerosol samples from Goiás with <i>P</i>. <i>brasiliensis</i> probe. <b>C:</b> aerosol sample from Rondônia, with DAPI. <b>D:</b> aerosol samples from Rondônia with <i>P</i>. <i>brasiliensis</i> probes. <b>E:</b> aerosol sample from Goiás with DAPI. <b>F:</b> aerosol sample from Goiás with <i>P</i>. <i>lutzii</i> probe. <b>G and I:</b> <i>Histoplasma capsulatum</i> with DAPI. <b>H:</b> <i>Histoplasma capsulatum</i> with <i>P</i>. <i>brasiliensis</i> probe (specificity control). <b>J:</b> <i>Histoplasma capsulatum</i> with <i>P</i>. <i>lutzii</i> probe (specificity control). <b>K:</b> isolate Pb01 (<i>P</i>. <i>lutzii</i>) with <i>P</i>. <i>lutzii</i> probe (positive control). <b>L:</b> isolate T16B1 (<i>P</i>. <i>brasiliensis</i>) with <i>P</i>. <i>brasiliensis</i> probe.

Brazilian sites and biomes where environmental detection (from soil, aerosol and armadillos) of <i>Paracoccidioides</i> spp. has been carried out.

<p>The collection areas encompass the states of Minas Gerais (MG), Goiás (GO) and Rondônia (RO) states, to São Paulo (SP) and Pará (PA). Circles outside of the map indicate the percentage of positivity in each area for <i>P</i>. <i>brasiliensis</i> (green) and <i>P</i>. <i>lutzii</i> (red) by <i>in situ</i> hybridization for aerosol samples. The circles outside of the map in black and grey indicate the percentage of positivity in each area for <i>P</i>. <i>brasiliensis</i> and <i>P</i>. <i>lutzii</i> by Nested PCR for soil and aerosol samples. The white circle indicates the negative detection in the evaluated areas (N.D. = Not detected). The armadillos indicate the number of collected animals and the positivity for isolation of <i>Paracoccidioides brasiliensis</i> (Pb) in each location of our study (in RO, GO and MG) and from previous works in SP [<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0004606#pntd.0004606.ref016" target="_blank">16</a>] and PA [<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0004606#pntd.0004606.ref033" target="_blank">33</a>]. The triangles (green), squares (yellow) and circles (red) show the distribution of the clinical isolates for cryptic species (S1, PS2 and <i>P</i>. <i>lutzii</i>) in previous studies [<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0004606#pntd.0004606.ref014" target="_blank">14</a>,<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0004606#pntd.0004606.ref031" target="_blank">31</a>].</p
