Changing epidemiological trend of Aeromonas species and ciprofloxacin sensitivity in South India.

Aeromonas species can cause a wide range of clinical infections. Several reports of drug resistance among the Aeromonas species have been reported, but our observations have differed. Here we present the changing susceptibility pattern of antibiotics for Aeromonas species over 14 years (January 2010-February 2024) at a tertiary care hospital in South India.

Burden of biocide resistance among multidrug-resistant bacteria isolated from various clinical specimens in a tertiary care hospital.

Background: Most studies on biocide resistance and its genetic determinants arise from environmental or food-borne microbial isolates and only a few from clinically relevant isolates.

Objectives: This study determines the proportion of biocide resistance against five commonly used biocides and detects biocide resistance genes among MDR bacterial isolates using PCR.

Methods: Consecutive MDR isolates (n ​= ​180) were included (30 each of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Staphylococcus aureus, and Enterococcus species) from clinical specimens of various inpatient units at JIPMER.

Exploring the use of Congo red agar in improving the serotyping of non-serotypeable Shigella with In-silico evidence.

Objectives: To assess if congo red could make non-serotypeable Shigella strains serotypeable and to employ molecular docking to determine the basis of the same phenomenon.

Methods: We used 42 bacterial strains of non-serotypeable Shigella collected from 2012 to 2019 for this study. Each bacterial strain was freshly inoculated onto congo red agar and incubated at 37° C for 18-24 h.
