Triatomines are of great concern in public health because they are vectors of Chagas' disease. This study presents an analysis of the species Triatoma melanosoma. The cytogenetic characteristics of triatomines include ...

The specific identification and systematic of triatomines have been based fundamentally on morphological observations. These organisms are classified into complexes and specific subcomplexes, principally for morphological ...

Seven species of the genus Eucalyptus were studied cytogenetically (E. deanei, E. dunni, E. grandis, E. maculata E. propinqua, E. saligna and E. tereticornis). The species showed a symmetrical karyotype with 2n=22 chromosomes, ...

Cytogenetic studies on Cycloramphus boraceiensis Heyer, 1983 collected in Picinguaba, Ubatuba, State of São Paulo are presented. The species has 2n=26 karyotype formed by metacentrics, submetacentrics, and one telocentric ...

The aim of this study was to characterize cytogenetically one population of the fish Moenkhausia sanctaefilomenae (Steindachner, 1907), with emphasis on the analysis of B chromosomes. The nucleolar activity in the B ...

Background: Chromosome aberrations (CA) are the main etiology of multiple congenital malformations, recurrent abortions and intellectual disability (ID) specifically of moderate and severe degree. They account for 0.3 to ...

The mapping of repetitive DNA sites by fluorescence in situ hybridization has been widely used for karyotype studies in different species of fish, especially when dealing with related species or even genera presenting high ...
