Phenotypic Changes in Phage Survivors of Multidrug-Resistant .

Unlabelled: Multidrug-resistant (MDR-KP) infections have become a major global issue in the healthcare sector. Alternative viable tactics for combating bacterial infections, such as the use of bacteriophages, can be considered. One of the major challenges in phage therapy is the emergence of phage-resistant bacteria.

Exposure to imipenem at sub-minimum inhibitory concentration leads to altered expression of major outer membrane proteins in Acinetobacter baumannii.

Aims: Acinetobacter baumannii is a nosocomial pathogen known to be multidrug-resistant (MDR), especially to drugs of the carbapenem class. Several factors contribute to resistance, including efflux pumps, β-lactamases, alteration of target sites, and permeability defects. In addition, outer membrane proteins (OMPs), like porins are involved in the passage of antibiotics, and their alteration could lead to resistance development.

Polymerase chain reaction-based typing methods and protein profiling analysis of isolated from environmental and clinical sources from South India.

is an opportunistic pathogen known for causing hospital-acquired infections. The natural habitat includes soil, water, sewage, and drains, but it is also detected in infected individuals' blood, pus, and respiratory pathways. Due to its resilient nature, it is known to be a causative agent for outbreaks.

Differential expression of outer membrane proteins and quinolone resistance determining region mutations can lead to ciprofloxacin resistance in Salmonella Typhi.

Multi-drug resistance in Salmonella Typhi remains a public health concern globally. This study aimed to investigate the function of quinolone resistance determining region (QRDR) of gyrA and parC in ciprofloxacin (CIP) resistant isolates and examine the differential expression of outer membrane proteins (OMPs) on exposure to sub-lethal concentrations of CIP in S. Typhi.

Evaluation of loop-mediated isothermal amplification assay for visual detection of Acinetobacter baumannii directly from soil and water sample from Mangalore.

Acinetobacter baumannii is a well-known nosocomial pathogen that commonly inhabits soil and water and has been implicated in numerous hospital-acquired infections. The existing methods for detecting A. baumannii have several drawbacks, such as being time-consuming, expensive, labor-intensive, and unable to distinguish between closely related Acinetobacter species.
