dc.description.abstract Abstract Introduction According to a study by the European Centre for Disease Prevention and Control (ECDC) for 2022-2023, Serratia spp. caused 54,406 cases of disease in 28 countries worldwide. Serratia liquefaciens is considered the second most frequently isolated organism from human clinical samples after Serratia marcescens. The aim of this study was to investigate the biological properties of S. liquefaciens isolated from chickens. Material and methods The study investigated a Serratia liquefaciens strain isolated in 2024 from chickens kept in a vivarium with clinical manifestations of gastrointestinal tract disorders. The aim of the study was to examine the strain S. liquefaciens. When studying the biological properties of the isolate, morphological characteristics, growth typicality, biochemical properties, pathogenicity for laboratory animals, and antibiotic sensitivity were taken into account. Results The isolated microorganism formed colonies typical of the Serratin genus, and the cells were motile at 37°C. The enzymatic profile matched the known characteristics of S. liquefaciens. The strain produced a denser biofilm at 23°C, exhibited pathogenicity in white mice, and showed resistance to several classes of antimicrobial agents. Based on the sequencing of a 16S rRNA gene fragment, the strain was deposited in the NCBI GenBank database under accession number PQ308601.1. Conclusions The results obtained suggest that the S. liquefaciens 1/2024 may be used as a reference strain for the differential diagnosis of enterobacteria, assessment of antimicrobial activity, and application as a laboratory control strain in experimental studies. en_US
dc.description.abstract Abstract Introducere Conform unui studiu ECDC pentru perioada 2022-2023, Serratia spp. a cauzat 54.406 cazuri de boală în 28 de țări din întreaga lume. Serratia liquefaciens este considerată al doilea cel mai frecvent izolat organism din probele clinice umane, după Serratia marcescens. Scopul studiului a fost de a investiga proprietățile biologice ale S. liquefaciens izolate de la pui. Material și metode Obiectul cercetării au fost tulpinile de S. liquefaciens, izolate în 2024 de la puii crescuți într-un vivariu cu manifestări clinice de afecțiuni ale tractului gastrointestinal. La studierea proprietăților biologice ale izolatului, s-au luat în considerare proprietățile morfologice, culturale, biochimice, patogenitatea pentru animalele de laborator și sensibilitatea la antibiotice. Rezultate Microorganismul izolat a format colonii tipice genului Serratia, iar bacteriile au fost mobile la 37°C. Activitatea enzimatică a izolatului a corespuns caracteristicilor S. liquefaciens. Bacteriile au fost capabile să formeze un biofilm mai dens la 23°C, au fost patogene pentru șoarecii albi și au prezentat semne de rezistență multiplă la agenții antimicrobieni. Pe baza rezultatelor secvențierii unui fragment al genei ARNr 16S, datele despre tulpină au fost introduse în GenBank NCBI sub numărul PQ308601.1. Concluzii Rezultatele obținute oferă motive pentru utilizarea tulpinii S. liquefaciens 1/2024 în calitate de standard pentru diagnosticul diferențial al enterobacteriilor, determinarea activității preparatelor antibacteriene, ca tulpină de control, de testare etc. en_US
