Antibiotic resistance
Abstract:
All infections follow the basic epidemiological pattern that if recognized early helps
to apply the measures to prevent and control pathologies. The epidemiological process
cannot be triggered in the absence of the microorganism’s reservoir and therefore it
is very important to control the potential reservoirs involved in nosocomial infections.
The etiological structure of nosocomial infections varies and includes a wide variety
of potentially or strictly pathogenic bacteria that have native or acquired proprieties
of virulence and antibiotic resistance. The aim of this project was to monitor the
potential role of the environmental risk factors involved in outbreak nosocomial
infections. The microbiological studies from an emergency hospital from Bucharest
have been started in January 2016 and samples were quarterly collected from drilling
and tap water, waste water, air and surfaces. There were performed quantitative
analyzes of microbiological contamination level and qualitative analyzes for
pathogenic and resistant bacteria detection. Some pathogenic bacteria have been
identified in the waste water and drilling water, indicating their interference. The
antibiotic resistance properties were observed especially in bacteria from waste
waters. Bacteria from vegetables from food preparation were detected in air samples
and surfaces tests from kitchen. The results indicated that environmental factors from
a medical unit could constitute a reservoir of microorganisms that can trigger
nosocomial infections.
