Avaliação de métodos genotípicos e caracterização de heterorresistência em pacientes com tuberculose
(Universidade Federal de Minas GeraisUFMG, 2018-12-20)
The difficulty in detecting resistance may lead to inadequate treatment and therapeutic failure and as consequence increase the spread of resistant bacteria, which can generate heteroresistance. The heteroresistance is the ...
Heterorresistência à colistina e polimixina b em Klebsiella pneumoniae: prevalência, métodos de detecção e perspectiva terapêutica.
(Universidade Federal de São Paulo, 2023-06-26)
Heterorresistência à colistina e polimixina B em Klebsiella pneumoniae refere-se a um fenômeno em que subpopulações aparentemente isogênicas se destacam em uma população bacteriana sensível, exibindo diferentes níveis de ...
Short communication: β-Lactam resistance and vancomycin heteroresistance in Staphylococcus spp. isolated from bovine subclinical mastitis
(2017-08-01)
The use of antimicrobial agents has led to the emergence of resistant bacterial strains over a relatively short period. Furthermore, Staphylococcus spp. can produce β-lactamase, which explains the survival of these strains ...
In vitro antimicrobials activity against endemic Acinetobacter baumannii multiresistant clones
(Open Learning on Enteric Pathogens, 2010-03)
BACKGROUND: Multidrug-resistant strains of Acinetobacter baumannii have been reported increasingly around the world. The administration of an association of antibiotics has been proposed to create an active combination and ...
O papel do estresse oxidativo e nitrosativo gerado pelos antifúngicos em Cryptococcus gattii e sua influência na heterorresistência ao itraconazol
(Universidade Federal de Minas GeraisUFMG, 2015-07-03)
Although the most accepted mechanisms of action of amphotericin B and azoles are related to ergosterol, it is possible that these drugs have other effects on the fungal cell. Moreover, heteroresistance is an adaptive ...
O papel do estresse oxidativo e nitrosativo gerado pelos antifúngicos em Cryptococcus gattii e sua influência na heterorresistência ao Itraconazol
(Universidade Federal de Minas Gerais (UFMG)Brasil--UFMG, 2018)
Genotypic determination of resistance and heteroresistance to clarithromycin in Helicobacter pylori isolates from antrum and corpus of Colombian symptomatic patients
(Universidad de los AndesMaestría en Ciencias BiológicasFacultad de CienciasDepartamento de Ciencias Biológicas, 2017)
The effectiveness of Helicobacter pylori first line treatment has decreased drastically with the raise of strains resistant to clarithromycin. Therapy failure have also been described in patients with infections by strains ...
Development of homogeneous expression of resistance in methicillin-resistant Staphylococcus aureus clinical strains is functionally associated with a β-lactam-mediated SOS response
(Oxford University Press, 2009-07)
Objectives: One of the main characteristics of methicillin-resistant Staphylococcus aureus (MRSA) from both hospitals and community is their heterogeneous expression of resistance. Recently, we reported new heterogeneous ...
Estudo do perfil populacional de Staphylococcus aureus resistente a meticilina de origem comunitária e hospitalar em hospital terciário, na busca de amostras hVISA
(Universidade Federal de UberlândiaBrasilPrograma de Pós-graduação em Imunologia e Parasitologia Aplicadas, 2017)
Increase in IS256 transposition in invasive vancomycin heteroresistant Staphylococcus aureus isolate belonging to ST100 and its derived VISA mutants
(Elsevier Science, 2016-05)
In Staphylococcus aureus, transposition of IS256 has been described to play an important role in biofilm formation and antibiotic resistance. This study describes the molecular characterization of two clinical heterogeneous ...
