Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test...

BACKGROUND Multidrug punch cards are frame cards with 28 plastic cavities filled with a patient's oral solid medication. They are used in primary care to facilitate medication management and to enhance adherence. Main criticism concerned handling difficulties and fading knowledge about medication of patients using them. This study aimed at exploring daily use, preferences, and adherence of prim...

Multidrug resistant organisms have been taunting the medical world for the last few decades. Even with new antibiotics developed, resistant strains have emerged soon after. With the advancement of nanotechnology, we investigated colloidal silver nanoparticles for its antimicrobial activity against Pseudomonas aeruginosa. This organism is a multidrug resistant which contributes to the high morbi...

Multidrug resistance is a major challenge to cancer chemotherapy. The multidrug resistance phenotype is associated with the overexpression of the adenosine triphosphate (ATP)-driven transmembrane efflux pumps in cancer cells. Here, we report a lipid membrane-coated silica-carbon (LSC) hybrid nanoparticle that targets mitochondria through pyruvate, to specifically produce reactive oxygen species...

Background: Resistance of Mycobacterium Tuberculosis is a condition in which Anti-Tuberculosis (OAT) drugs are unable to kill the germs. One type resistance Multidrug Resistant Tuberculosis. (MDR-TB) TB caused by bacteria that resistant 2 types OAT, namely INH and Rifampin. The consequences if OAT deterioration health, increased costs, prolonged treatment, high rates therapy failure death.&#x0D...

However, our approach could be used in contexts with a higher prevalence of multidrug-resistant tuberculosis than Tanzania because both the eff ect on the level of multidrug-resistant tuberculosis diagnosed and...

BACKGROUND Lower respiratory tract infections are among important causes of morbidity and mortality for all age groups. The emergence of multidrug resistant Gram-negative bacilli is an issue of increasing concern. MATERIALS AND METHODS A retrospective study including respiratory specimens (sputum and BAL) was conducted in our tertiary care centre. Samples were processed for microscopy, cultur...

The nature of the broad substrate specificity phenomenon, as manifested by multidrug resistance proteins, is not yet understood. In the Escherichia coli multidrug transporter, MdfA, the hydrophobicity profile and PhoA fusion analysis have so far identified only one membrane-embedded charged amino acid residue (E26). In order to determine whether this negatively charged residue may play a role i...

ratory infection. It causes nosocomial infections in immunocompromised hosts. Recent studies indicate that an increasing percentage of Klebsiella strains are becoming resistant to multiple antimicrobial agents. In particular, infection with K. pneumoniae that are resistant against the b-lactams and fluoroquinolones are especially severe clinical problems. Furthermore, such resistant K. pneumoni...
