“…However, the growth of numerous environmental molds was observed, including Penicillium spp., Aspergillus spp., Trichoderma spp., and Geotrichum spp. These fungi were reported by Brandsberg et al, 16,58 who demonstrated that they shared a microhabitat with H. capsulatum and acted as strong competitors for space and nutrients, which are factors that affect the survival of fungi in soil. 9,16 This finding is also associated with the stabilization of organic matter by composting because composting is a decomposition process in which multiple microorganisms, such as fungi, actinomycetes, and bacteria, 51,59 take part.…”

is the causative agent of histoplasmosis and this fungus inhabits soils rich in phosphorus and nitrogen that are enriched with bird and bat manure. The replacement of organic matter in agroecosystems is necessary in the tropics, and the use of organic fertilizers has increased. Cases and outbreaks due to the presence of the fungus in these components have been reported. The Instituto Colombiano Agropecuario resolution 150 of 2003 contains the parameters set by the Colombian Technical Standard (NTC 5167) on the physicochemical and microbiological features of fertilizers, but it does not regulate the search for . The aim of this study was to demonstrate presence in organic fertilizers by nested polymerase chain reaction (PCR). A total of 239 samples were collected: 201 (84.1%) corresponded to organic fertilizers, 30 (12.5%) to bird excrement, and 8 (3.4%) to cave soils. The Hc100 nested PCR had a detection limit of 0.1 pg/µL and a specificity of 100%. A total of 25 (10.5%) samples were positive and validated by sequencing. Seven of the positive samples represented locations where was previously detected, suggesting the persistence of the fungus. No significant correlations were detected between the physicochemical and microbiological parameters with the presence of by nested PCR, indicating the fungus existence in organic fertilizers that complied with the NTC 5167. The Hc100 nested PCR targeting standardized in this work will improve the evaluation of organic fertilizers and ensure the prevention of outbreaks and cases due to manufacturing, marketing, and use of fertilizers contaminated with.

“…In vitro it tolerates 5% additional salt [39]. This property enables the fungus to reside in somewhat osmotic environments such as dry bat faeces [46], chicken coops [47] and bird guano at their roosting sites [48]. It occurs in brackish and salt water, such as submerged wood in estuaria [49] and tide-washed areas and marine soil [50,51].…”
