Structura etiologică a bacteriilor din familia Enterobacteriaceae care provoacă boli diareice acute

Abstract

The research was carried out between 2019 and 2021, in the microbiological laboratory of Public Health Medical Institution AMT Buiucani. During the study period, 1738 samples were processed, 347 strains (19.96%) were isolated and 12 etiological agents from the Enterobacteriaceae family were identified: 58.3% – conditionally pathogenic (Klebsiella spp., Enterobacter spp., Serratia spp., Proteus spp., Citrobacter spp., Escherichia coli haemolytica, Morganella spp.), 16.7% – pathogenic (Shigella spp., Salmonella spp.) and 25% – gram negative non-fermentative (Pseudomonas aeruginosa, Acinetobacter spp., Aeromonas spp.). From the total number of positive samples, the largest share of conditionally pathogenic microorganisms belongs to Klebsiella spp. (43.8%), among pathogenic – Salmonella spp. (2.59%), among the causative agents of enterocolitis Pseudomonas aeruginosa species (6.92%). Positive results for the presence of etiological agents were reported both in adults and in children 0-17 years old, constituting 63.98% and 36.02% respectively. The highest proportion of enterobacteria strains both in adults and in children 0-17 belongs to Klebsiella spp. – 38.3% and 53.6% respectively. During the study period, the dominant among microorganisms from the Enterobacteriaceae family was the genus Klebsiella, the share of which varied between 41.03% and 47.97%.
