Abstract

The aim of this study was to map the spectrum of microorganisms belonging to the genus Acinetobacter in domestic animals with a specific focus on the prevalence of Acinetobacter pseudolwoffii. Additionally, the susceptibility of isolates to antimicrobial agents was determined. In the period from January 1, 2014, to August 31, 2015, a total of 9 544 samples originating from gross lesions and pathological processes of animals exhibiting clinical symptoms of the disease were examined across 41 districts in the Czech Republic. The examinations were carried out using culture methods involving meat-peptone blood agar and Endo agar under aerobic conditions at a temperature of 37 ± 1 °C for 18-24 hours. Isolates were confirmed using molecular phenotypic method MALDI-TOF MS with the MBT Compass Library Revision L 2020 covering 3 239 species/entries (9 607 MSP) from Bruker Daltonics company. Out of the 108 isolates (prevalence 1.13%), 14 species of Acinetobacter spp. were identified, with 5 isolates remaining unclassified as species. A. pseudolwoffii was the predominant species isolated in 25 cases (prevalence 0.26%). Antimicrobial susceptibility was determined for 12 antimicrobials by the disc diffusion method, with A. pseudolwoffii isolates exhibiting the lowest susceptibility to ceftazidime (32%) and co-trimoxazole (60%).
