Abstract

Introduction:
PSEUDOMONAS SPP. is an opportunistic infections resulting in UTI and others pose a significant threat in health facilities. This organism is characterized by being rods, motile, aerobic, nonfermentative, and Gram-negative, possessing exceptional capabilities to withstand various common antimicrobial drugs. As a result, they have become one of the most prominent sources of infections acquired within health facilities owing to their natural resistant characteristics. This bacterial genus can produce UTI, respiratory tract infection, gastrointestinal infection, skin infection, blood infection (bacteremia), tissue infection, and bone or joint infection among many others. Being able to endure tough environmental and physiological conditions while requiring minimum amounts of nutrition makes them capable of survival both in hospitals and in the general community. In the case of health facilities, these pathogens may be transferred either through contact with surfaces or medical equipment or even through the transmission by healthcare personnel. It is well known that they are one of the most frequent isolates of non-fermentative Gram-negative bacilli in clinical specimens. Moreover, they exhibit high resistance to a number of disinfectants.3 High-risk patients are burn patients, immunecompromised patients, patients who have been hospitalized for a long period of time, patients who have had prosthetic surgery performed on them, and patients with chronic diseases. With the rise in infection by Pseudomonas spp., they present a great challenge for the healthcare setting and public health sector. Thus, this research was carried out to identify the incidence rate of Pseudomonas spp. strains in hospitalized patients in various wards in Jan Sewa Hospital, North India.

Aim:
Pseudomonas spp. is a rod-shaped, motile, aerobic, non-fermenting, gram-negative bacterium and a major human pathogen belonging to the family Pseudomonadaceae. It causes several nosocomial infections, including pneumonia, urinary tract infections, surgical site infections, otitis externa, and soft tissue infections.

Material and Methods:
The study was conducted from the period of November 2024 to April 2025 and involved the prevalence of Pseudomonas spp. isolates among admitted patients' specimens in Jan Sewa Hospital. The collected specimens were examined using different methods and cultured on different media in the hospital. The isolated bacteria were identified according to their morphological and biochemical properties.

Results:
Out of 1664 total inpatient samples processed, 78 were positive for Pseudomonas spp., giving an overall prevalence of 4.69%. Pseudomonas isolates were most frequently obtained from pus samples (37.17%), followed by BAL (25.64%) and sputum (15.38%). The majority of infections occurred in adults (67.94%), followed by elderly patients (30.76%). Male patients accounted for 64.10% of infections, while females constituted 35.90%.

Conclusion:
Most of the Pseudomonas spp. strains were isolated from pus, BAL, and sputum samples. Adults and male patients were more frequently affected.
