Study showed that synthesis of specific IgG occurs in rabbits immunized with recombinant outer membrane protein F (OprF) of Pseudomonas aeruginosa and that these antibodies inhibit grow of P. aeruginosa in vitro. In vivo studies on mice showed that rabbit hyperimmune sera and recombinant OprF are both able to protect animals from intraperitoneal challenge with P. aeruginosa.

Background: Respiratory tract infections (RTIs) are one of the leading causes of morbidity and mortality worldwide. The increase in antimicrobial resistance in respiratory pathogens poses a major challenge to the effective management of these infections.
Objective: To investigate the distribution of major pathogens of RTIs and their antimicrobial resistance patterns in a tertiary care hospital and to develop a mathematical model to explore the relationship between pathogen distribution and antimicrobial resistance.

The current study was designed to evaluate the antibacterial, antibiofilm, and biofilm inhibitory potential of six medicinal plants, including Trachyspermum ammi, Trigonella foenum-graecum, Nigella sativa, Thymus vulgaris, Terminalia arjuna, and Ipomoea carneaid against catheter-associated bacteria (CAB). Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.

Introduction: Cefiderocol is a parenteral catechol-type siderophore cephalosporin, which has been approved for the treatment of gram-negative bacterial infections. Its activity among the carbapenem-resistant gram negative bacilli (CR-GNBs) in India is largely unknown.
Methodology: We tested in-vitro susceptibility of cefiderocol in 84 CR-GNB [ carbapenem-resistant Acinetobacter baumannii (CRAB), carbapenem-resistant Pseudomonas aeruginosa (CRPA) , carbapenem-resistant Escherichia coli (CREC) and carbapenem-resistant Klebsiella pneumoniae (CRKP)] by broth microdilution(BMD) and disc diffusion (DD) using Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints and concordance of DD was compared with BMD.
