[Pseudomonads as a marker of the sanitary-epidemiological state of maternity institutions]
Abstract:
In the process of the epidemiological supervision of 4 maternity hospitals in Tyumen 453 Pseudomonas strains, classified with 9 species, were isolated and studied. The overwhelming majority of the strains isolated from nursing articles and medical equipment were classified with P. aeruginosa (86.75 +/- 1.68%) and P. putida (7.11 +/- 1.27%). In the structure of Pseudomonas isolated from humans these species constituted 51.11 +/- 7.45% and 26.67 +/- 6.69% respectively. High occurrence of Pseudomonas contamination of nursing articles and medical equipment in postnatal wards (11.48 +/- 0.82%) and in infants wards (6.92 +/- 0.58%) was established. Sinks of wash-stands (3.76 +/- 1.3-28.5 +/- 2.15%), compressors for the reanimation of infants (11.1 +/- 10.47%), faucets (1.69 +/- 0.7-5.29 +/- 0.92%), etc. were found to be the most contaminated objects which could be the factor of Pseudomonas transmission. The inclusion of bacteriological control into the system of epidemiological supervision in maternity hospitals facilitates the timely detection of unfavorable epidemiological situation and makes it possible to take the necessary measures with a view to decrease the functioning of mechanisms of Pseudomonas transmission well in advance.
Insights
Pseudomonas contamination is high on medical equipment in maternity hospitals, especially P. aeruginosa. Regular bacteriological control is crucial for early detection and prevention of transmission in these critical healthcare environments.
Area of Science:
- Microbiology
- Epidemiology
- Healthcare-associated infections
Context:
- Maternity hospitals are critical environments for vulnerable populations.
- Pseudomonas species pose a significant risk in healthcare settings.
- Understanding contamination sources is key to infection control.
Purpose:
- To investigate the prevalence and species distribution of Pseudomonas in Tyumen maternity hospitals.
- To identify common sources and transmission routes of Pseudomonas contamination.
- To evaluate the role of bacteriological control in preventing Pseudomonas spread.
Summary:
- 453 Pseudomonas strains from 9 species were isolated and studied in 4 Tyumen maternity hospitals.
- P. aeruginosa and P. putida were the predominant species found on medical equipment and from human samples.
- High contamination rates were observed on nursing articles, medical equipment, and specific fixtures like sinks and faucets, indicating potential transmission pathways.
Impact:
- Establishes the significant presence of Pseudomonas, particularly P. aeruginosa, in maternity hospital environments.
- Identifies specific high-risk contamination sites, including wash-stand sinks, infant reanimation compressors, and faucets.
- Highlights the importance of integrating bacteriological control into epidemiological surveillance systems for timely intervention and reduced transmission.
