Advances in the classification of the human pathogen Histoplasma capsulatum H. The present mini-review highlights the great genetic plasticity of H. Important records with different molecular tools, mainly single- or multi-locus sequence analyses developed with this fungus, are discussed. La presente revisión destaca la importante plasticidad genética de H. Este artículo forma parte de una serie de estudios iw en el «V International Workshop: Molecular genetic approaches to the study of human pathogenic fungi» Coassification, México, The scientific history of the pathogenic fungus Histoplasma capsulatum began with the histopathological findings, published by Samuel Taylor Darling inin tissues of a patient from Martinique, who what is the importance of classification in biology working on the construction of the Panama Channel.

Later, inHenrique da Rocha Lima inferred the mycotic nature of this pathogen, characterizing it as a yeast. Before the description of the sexual state of H. In the environment, this organism grows preferentially in bat and bird guano that contains high concentrations of nitrogen and phosphorus in addition to other micronutrients.

The biological species H. These varieties were identified by their micromorphologies, geographic distribution, host-association, and clinical forms of the disease. Currently, with the advent of molecular techniques to classify fungal species, these taxonomic varieties have been included in a molecular taxonomy based on the phylogenetic species concept. Taylor et al. However, some pathogenic fungi show few informative characters thereby leading to skewed, controversial, and classificztion classifications.

First, Vincent et al. Class 1 included only the Downs strain of H. Spitzer et al. Relevant molecular classifications of Histoplasma capsulatum isolates. Keath et al. Biolgy is noteworthy that, from the initial proposal of Vincent et al. Later, Poonwan et al. Jiang et al. As a result, they suggested that this method could be useful for what is the importance of classification in biology isolates from other classifications.

The latter authors suggested that RAPD-PCR profiles with suitable random primers could be used for classifying fungal isolates in accordance with their source and classificqtion distribution. Afterwards, Zancopé-Oliveira et al. Additional molecular studies by Carter et al. The analyses of H. Today, advances in fungal classification are supported by robust analyses of the sequences of gene fragments that provide important genetic informative sites to separate clusters of isolates.

The statement of a large number of these sites associated with several loci would establish a clear relatedness among fungi and would contribute to a better understanding of the intra- and inter-specific diversity of classifiction species. It is an excellent molecular tool to characterize genetic diversity in different microorganisms. Currently, the identification of these species are revealed by phylogenetic, genealogic, or gene concordance species concepts, which group the organisms according to the changes in their nucleic acids.

Two pioneer MLS studies, which contributed to the phylogenetic classification of H. What is the importance of classification in biology the last report, using isolates from 25 countries, Kasuga et al. With the exception of the Eurasian clade, seven clades were considered to be phylogenetic species. Consistent with the Kasuga et al. Geographic distribution of the H. Data were obtained from Kasuga et al. Some individuals of the taxonomic varieties H.

Following the Kasuga et al. Later, Muniz et al. Finally, Balajee et al. These authors extracted the DNA of H. Blology study included, as reference, 82 sequences of the fungal strains previously reported by Kasuga et al. Based on unpublished results from our laboratory, with 28 H. Similarities and genetic distances among their sequences demonstrated that fungal isolates recovered from cave-dwelling bats and the two clinical reference strains from the central states of Mexico Morelos, Puebla, and Hidalgo were grouped independently from most H.

This finding matches previous data published by Taylor et what is the importance of classification in biology. In addition, a single H. Thus, the topology of the two concatenated trees that were generated by an MLS analysis using the five aforementioned what is the importance of classification in biology loci were able to discriminate the high genetic diversity of this fungus, thereby contributing to the knowledge of the pathogen Fig.

Concatenated phylogenetic trees of Mexican H. Phylogenetic analyses were conducted as follows: 1 the neighbor-joining NJ method using the Kimura what is the importance of classification in biology model 17 ; and 2 the maximum parsimony MP method using the close-neighbor-interchange algorithm. Trees were generated with replicates. Fourteen of the Mexican H.
