Prevalence of Ophidiomyces ophiodiicola detected by qPCR in individual snake species on military installations in 2018.
Fig 1.
Spatial distribution of Ophidiomyces ophiodiicola detection in snakes on military installations sampled in 2018.
White = states not sampled, light grey = states with no detection of O. ophiodiicola, dark grey = states detected with O. ophiodiicola. White asterisks indicates a state/territory identified with O. ophiodiicola for the first time in this study.
Fig 2.
Spatial distribution and prevalence of ophidiomycosis in snakes on military installations sampled in 2018.
Negative = no clinical signs and no qPCR detection of Ophidiomyces ophiodiicola; (Ophidiomyces) Present = qPCR positive AND no clinical signs; Possible (ophidiomycosis) = clinical signs present AND no qPCR detection; Apparent (ophidiomycosis) = qPCR detection AND clinical signs.
Fig 3.
Phylogeny-based bipartite network for snakes sampled for ophidiomycosis on military lands in 2018.
Blue nodes represent sampled snake species aligned with the corresponding leaf in the phylogenetic tree. The gray node represents the negative category, the orange node represents possible ophidiomycosis, the dark purple node represents Ophidiomyces present, and the red node represents apparent ophidiomycosis. A species node is connected to an ophidiomycosis node if snakes of a given species were classified into the given category. Node size is weighted by prevalence of the ophidiomycosis category, and links are weighted by the proportion of snakes of the given species in the given category.
Fig 4.
Bipartite network and projections with snake species grouped by region for snakes sampled for ophidiomycosis on military installations.
Blue nodes represent regions of the US. The gray node represents the ophidiomycosis negative category, the orange node represents possible ophidiomycosis, the dark purple node represents Ophidiomyces present, and the red node represents apparent ophidiomycosis. Ophidiomycosis category node size is proportional to the prevalence of the category. (A) Bipartite network with one set of nodes representing seven US regions and the other set representing ophidiomycosis categories. Nodes are connected if snakes from a given region were classified into the given ophidiomycosis category, and the links are weighted based on the proportion of snakes of the given region in the given category, (B) Region-region network projection with region nodes connected if they share a connection with an ophidiomycosis category, (C) Disease-disease network projection with ophidiomycosis nodes connected if they share a link with a region.
