Draft Genome Sequences of Clinical and Environmental Isolates of Aspergillus tamarii from Colombia.

Aspergillus is a very diverse genus of fungi that are common in the environment and can affect human health. Here, we report the draft genome sequences of two Colombian isolates of Aspergillus tamarii, an emerging pathogenic species. One isolate was obtained from an infected patient and the other from the environment in a hospital.

Agrobacterium tumefaciens-mediated transformation of Paracoccidioides brasiliensis.

Paracoccidioides brasiliensis is the causative agent of paracoccidioidomycosis, an important mycosis endemic to Latin America. As the tools to study gene function in P. brasiliensis are only in the early stage of development, there is presently no system that allows for both the delivery and integration of exogenous nucleic acids into its genome. We report in this paper the transformation of the yeast phase of P. brasiliensis (ATCC-60855) with Agrobacterium tumefaciens (GV3101) carrying the vector pAD1625. The microorganisms were co-cultivated for 2 days and then incubated for 10 days at 35 degrees C on selective media. PCR and dot-blot targeted at a fragment of 222 bp from the hph (hygromycin phosphotransferase) gene which confers Hygr confirmed the transformation of P. brasiliensis.
