Characterization of In Vitro Resistance to Linezolid in Mycobacterium abscessus

Microbiology Spectrum, 2023
Single-step selection of Mycobacterium abscessus mutants resistant to linezolid yielded high-level resistance at a low frequency that was associated with mutations in 23S rRNA or the ribosomal protein L3.

Drug coverage in treatment of malaria and the consequences for resistance evolution--evidence from the use of sulphadoxine/pyrimethamine. [PDF]

, 2010
BACKGROUND\ud \ud It is argued that, the efficacy of anti-malarials could be prolonged through policy-mediated reductions in drug pressure, but gathering evidence of the relationship between policy, treatment practice, drug pressure and the evolution of ...

Whole genome sequencing data of 1110 Mycobacterium tuberculosis isolates identifies insertions and deletions associated with drug resistance

BMC Genomics, 2018
Background Drug resistance in Mycobacterium tuberculosis (MTB) is one of the major challenges in tuberculosis (TB) treatment. However, known mutations cannot explain all of the cases of resistance and little research has focused on the relationship ...

Molecular mechanisms of drug resistance in natural Leishmania populations vary with genetic background [PDF]

, 2012
The evolution of drug-resistance in pathogens is a major global health threat. Elucidating the molecular basis of pathogen drug-resistance has been the focus of many studies but rarely is it known whether a drug-resistance mechanism identified is ...

HIV and antiretroviral drug resistance

Журнал инфектологии
The article presents modern views on the causes of the formation of drug-resistant HIV strains. The main reasons for the ineffectiveness of antiretroviral therapy are low patient adherence to treatment, lack of combination therapy, and high rate of viral

Primary HIV-1 resistance: Persistence of transmitted drug resistance mutations [PDF]

Archives of Biological Sciences, 2012
Transmitted drug resistance (TDR) is one of the consequences of the high variability of HIV-1. The widespread use of antiretroviral therapy for the treatment of HIV-1 infection results in a large circulating pool of resistant virus variants.

The role of the HIV-1 protease substrate in therapy resistance [PDF]

, 2015
In Switzerland and Germany up to a half of the first-line regimens include protease inhibitors (PIs) [1, 2]. Although in the Swiss HIV Cohort Study (SHCS) most patients under antiretroviral therapy (ART) have suppressed viral loads [3], every third ...

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
