[Pseudomonas putida: identification, antibiotic sensitivity and pathogenicity (author's transl)]

Area of Science:

• Microbiology
• Bacteriology

Context:

• Pseudomonas putida is an opportunistic pathogen found in clinical and hospital environments.
• Understanding the characteristics of P. putida strains is crucial for infection control and treatment.

Purpose:

• To characterize 51 strains of Pseudomonas putida isolated from clinical specimens and hospital environments.
• To determine the biotype, antibiogram, and experimental virulence of these P. putida strains.

Summary:

• Fifty-one Pseudomonas putida strains were analyzed using physiological, biochemical, and nutritional characterization.
• The majority of strains (48/51) belonged to biotype A, with 3 strains classified as biotype B.
• Antibiogram analysis revealed resistance to carbenicillin and sensitivity to kanamycin.
• Experimental virulence studies in mice indicated low pathogenicity, with no correlation between virulence and bacterial source.

Impact:

• This research provides valuable data on the phenotypic diversity and antimicrobial susceptibility of P. putida.
• Findings contribute to the understanding of P. putida epidemiology and potential clinical significance.
• The study highlights the need for appropriate antibiotic selection in treating P. putida infections.
