Busatto,Caroline; Vianna,Júlia Silveira; Silva,Ana Barbara Scholante; Basso,Rossana; Silveira,Jussara; Groll,Andrea Von; Ramis,Ivy BastosABSTRACT Objective: Nontuberculous mycobacteria (NTM) are a heterogeneous group of bacteria that are widely distributed in nature and associated with opportunistic infections in humans. The aims of this study were to identify NTM in patients with suspected tuberculosis who presented positive cultures and to evaluate the genetic diversity of strains identified as Mycobacterium avium. Methods: We studied pulmonar...
Sporothrix spp. EVALUATION IN SOIL OF A HYPERENDENIC AREA FOR SPOROTRICHOSIS IN...
Poester,Vanice Rodrigues; Mendes,Josiara Furtado; Groll,Andrea Von; Klafke,Gabriel Baracy; Brandolt,Tchana Martinez; Xavier,Melissa OrzechowskiAbstract The increase in zoonotic sporotrichosis cases has become a public health problem in hyperendemic areas for the feline disease. Domestic cats involvement in this transmission and the continuous contact of these animals with soil suggest that the environment may be an essential source and/or reservoir of Sporothrix spp. Thus, the current study aimed to evaluate the presence of Sporothrix spp. in the soil...

Nitrate reductase assay using sodium nitrate for rapid detection of multidrug r...
Macedo,Maíra Bidart; Groll,Andrea Von; Fissette,Krista; Palomino,Juan Carlos; Silva,Pedro Eduardo Almeida da; Martin,AnandiWe validated the nitrate reductase assay (NRA) for the detection of multidrug-resistant Mycobacterium tuberculosis (MDR-TB) using sodium nitrate (NaNO3) in replacement of potassium nitrate (KNO3) as nitrate source. NaNO3 is cheaper than KNO3 and has no restriction on use which facilitates the implementation of NRA to detect MDR-TB.
