As dermatomicoses dos animais domésticos constituem zoonoses importantes, urna vez que estes mantêm estreito contato com a espécie humana, dada a alta infectividade observada nesses processos. Relata-se a ocorrência de sete surtos de dermatomicoses, um por M. gypseum envolvendo um gato e um indivíduo do sexo feminino e os outros por M. canis envolvendo 20 indivíduos da espécie humana (adultos, jovens e crianças de ambos os sexos), 5 cães, 16 gatos e um macaco gibão (Hylobates lar).Descritores: Dermatomicose, epidemiologia.

IntroduçãoAs dermatomicoses dos cães e gatos constituem zoonoses de importância, uma vez que estes são, dentre os animais domésticos, os que mantêm mais estreito contato com a espécie humana, particularmente com as crianças, altamente susceptíveis a esses processos 21,29,30 . Por representarem alta percentagem das dermatopatias, os animais assumem papel relevante na clínica veterinária. As lesões clinicamente evidentes preocupam o proprietário, levando-o a procurar ajuda do profissional para diagnóstico, tratamento e orientação 6,7,10,13 . Numerosos surtos por espécies do gênero Microsporum são referidos na literatura internacional. Assim, verificam-se relatos de M. canis determinando dermatomicose no homem e, concomitantemente, nos animais em diferentes continentes como,

The Quadrilátero Ferrífero is an important mineral province located in Southern São Francisco craton, SE Brazil. Its prominent feature is the Gandarela syncline that was formed as part of the regional deformation event in the southernmost part of the craton at ca. 2,000 Ma. The syncline exposes several economically important units of Rio das Velhas and Minas supergroups, widely known for their gold and iron ore mineral deposits. This work focused on the upper Minas Supergroup-Cercadinho Formation and Sabará Group in the Gandarela syncline. We showed detail stratigraphic surveys combined with U-Pb detrital zircon analysis. Data reveal the development of high-to low-density turbidity systems. The first one is related to the deposition of Cercadinho Formation that marks the siliciclastic infilling of the Minas basin. For the Sabará Group, a fine turbidite system of foredeep depocenter is inferred. The detrital zircon analysis indicates that their sediments were derived from Archean, Rhyacian, and Orosirian exhumed terrains, besides granitoids positioned to the south and east of Quadrilátero Ferrífero. We proposed the age of 2,036 ± 25 Ma as the maximum age of deposition of Sabará Group, whose sedimentation occurs in the first stages of Minas accretionary orogeny.

The Quadrilátero Ferrífero metallogenetic province is located in the southernmost portion of the São Francisco craton, SE Brazil. The Tamanduá and Cambotas ridges stand out topographically in the northeastern portion of Quadrilátero Ferrífero and show NE-SW and N-S directions, respectively. Those ridges involve metasedimentary rocks of the Tamanduá Group bounded by a fault system. Due to stratigraphic and structural complexities, there is little consensus about the maximum sedimentation age and the stratigraphic position in which Tamanduá Group sediments were deposited. In this work, we took advantage of the excellent exposures in the Tamanduá and Cambotas ridges to present detailed stratigraphic observations combined with U-Pb zircon geochronological data from samples of different stratigraphic levels of Tamanduá Group. Furthermore, we provide U-Pb data from samples of the intrusive Pedra Formosa Suite that cut the whole Tamanduá sequence in the study area. Our observations showed that the Tamanduá Group represents a rift-sag basin-fill succession developed along the eastern border of the São Francisco paleoplate. The basal metaconglomerate and metasandstone package grades upward into marine metasandstone and phyllite. Detrital zircon obtained from the basal unit, Antônio dos Santos Formation, reveals maximum depositional ages between ca. 1981 and 1770 Ma. The upper succession, Cambotas Formation, shows a maximum depositional age from 1769 to 1740 Ma. The Pedra Formosa Suite shows zircons that crystallized at ca. 1740 Ma. The stratigraphic framework and the Orosirian-Statherian ages suggest a correlation with the first rifting event within the São Francisco paleoplate, the precursor of Paleo-to Mesoproterozoic Espinhaço basin.
