To describe the risk factors and molecular epidemiology of nosocomial bloodstream infections caused by extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in a tertiary care hospital. ⋯ ESBL-producing K. pneumoniae clones were detected throughout the hospital. Use of broad-spectrum cephalosporins is the most important risk factor associated with the proliferation of ESBL-producing strains.

Compassionate use of linezolid for bone and joint infections has been reported and hematological adverse reactions are a cause for concern. A similar experience in Asian people has not been reported. ⋯ Linezolid is an effective salvage agent for bone and joint infections. However, adverse effects, especially hematological reactions, may cause drug discontinuation.

The increasing emergence of serious multidrug-resistant (MDR) Gram-negative infections has led to a new health-care crisis. These infections predominately include MDR Pseudomonas aeruginosa, extended-spectrum beta-lactamase-producing Enterobacteriaceae and MDR Acinetobacter baumannii. ⋯ The increasing use of broad-spectrum antibiotics and lack of good stewardship have contributed to the increase in these MDR organisms. This review focuses on the main MDR Gram-negative infections contributing to the current crisis in health care, their mechanisms of resistance and various treatment options for empiric therapy.

To find out an alternative strategy to antibiotic usage against bacterial infection. ⋯ The present study identified the anti-QS activity of A. comosus, M. paradiciaca, M. zapota and O. sanctum. An AHL-inactivating compound from these plant sources can be used as an alternative to antibiotic compounds to prevent AHL-mediated bacterial infection in higher organisms.

Due to its increased non-susceptibility rates, Klebsiella pneumoniae has emerged as one of the most problematic pathogens. ⋯ The effectiveness of carbapenems has been compromised and the increase in resistance to colistin is rapid and steep.
