“…The role of the curator is essential and must be a minimum criterion in the management, organization, and institutionalization of biological collections [9]. In addition to the valuable material preserved in collections, microbial collections provide essential services that support research, technological development, and innovation [10]. Around 97% of the collections offer specialized services such as deposit and supply of strains, taxonomic identification, consultancy, courses and training, and others, and a significant proportion of these collections provide more than one kind of service (Figure 15).…”

As part of a Ministry of Science, Technology, and Innovation initiative, the Brazilian Societies of Botany, Microbiology, Virology, and Zoology conducted a comprehensive evaluation of biological collections in Brazil. This assessment aimed to gather insights into the current state of these collections, with the goal of providing support for future public policies, including financial subsidies and prioritization policies. In this context, we present the findings related to microbiological collections, essential to ex situ biodiversity conservation and crucial in supporting research, development, and innovation. A survey was distributed to public and private institutions across Brazil, yielding responses from 168 microbiological collections representing 79 different entities. Notably, 73 of these collections are affiliated with public research institutions and universities, underscoring the State’s pivotal role in preserving and safeguarding Brazilian microbial diversity. The primary taxonomic groups encompass bacteria (found in 70.24% of collections) and fungi (comprising 52.98% of collections), sourced from diverse Brazilian ecosystems and biomes, including those that contain several type strains. Furthermore, the collections preserve microorganisms harboring biotechnological potential applicable to environmental protection, public health, industry, and agribusiness. Despite these promising economic and biotechnological prospects, our meticulous data analysis has revealed significant limitations and vulnerabilities, especially regarding physical infrastructure and human resources, emphasizing the urgent need for interventions to guarantee their sustainability.

As part of a project ordered by the Ministry of Science, Technology and Innovation of Brazil, an assessment of Brazilian biological collections was conducted by the Brazilian Societies of Botany, Microbiology, Virology and Zoology to obtain data on the current state of these collections. The goal was to provide subsidies for future public policies, including financial support and prioritization policies. Herein, we present the results of the microbiological collections, which play a fundamental role in the ex situ conservation of biodiversity and support research, development and innovation. A survey was sent to public and private institutions in Brazil and answered by 168 microbiological collections from 79 different institutions. Among these, 73 comprise public research institutions and universities, demonstrating the State's importance in preserving and safeguarding Brazilian microbial diversity. The main taxonomic groups are bacteria (present in 70.24% of the collections) and fungi (52.98% of the collections) from different Brazilian ecosystems and biomes, including several type strains. Furthermore, the collections preserve microorganisms with biotechnological potential for application in environmental protection, public health, industry, and agribusiness. However, despite all these economic and biotechnological potentials, the data analysis showed serious limitations and fragilities, especially regarding physical infrastructure and human resources, and raises alerts about the risk that Brazilian collections are subjected to.

“…Microbiological collections are considered important tools for obtaining information and have evolved over time due to the growing demands of different scientific areas [ 14 ]. Currently, their function is the acquisition, preservation, identification, cataloging and distribution of authenticated microorganisms to support scientific research, epidemiological studies and the development of bioproducts among others [ 15 ].…”

The Mating Type (MAT) and Virulence of Sporothrix schenckii sensu stricto Isolates Maintained in Culture Collection

In an attempt to determine the mating type of different Sporothrix schenckii sensu stricto isolates that remained viable after a long period of preservation in a culture collection and to correlate them with the degree of virulence/pathogenicity, a PCR technique using primers designed for the sequences of MAT1-1-1 and MAT1-2-1 genes and a murine experimental model were used. The results showed that there was no correlation between the mating type and virulence among the isolates. Furthermore, different degrees of virulence/pathogenicity, ranging from high to low, were found among them based on different virulence parameters. It was assumed that the long period of preservation favored the changes, yielding the isolation of variants. Thus, we believe that new technologies for studies on factors can improve our knowledge of the pathogenesis of sporotrichosis.
