Background: S. paucimobilis is a Gram-negative bacterium widely distributed in nat-ural environments, hospitals, and highly resistant to disinfectants. Various infections in humans have been reported as sporadic case reports. This study aimed to quantify the presence of S. paucimobilis in the fauces microbial landscape of children with re-current tonsillitis and the sensitivity of isolates to antimicrobials. Methods: The bac-teriological method of research was used. The final identification was performed on Vitec-2 compact bioMarieux automatic bacteriological analyser (France). Antimicro-bial susceptibility was determined using the measurement of the inhibition zone diameters (EUCAST standardised disk diffusion methodology) on the Mueller-Hinton (MH) agar. Results: Three isolates of S. paucimobilis were isolated from nasopharyngeal material from five children. The growth of S. paucimobilis was observed in three sectors of Columbia agar with 5% sheep blood (bioMarieux, France), as well as other bacterial species that were most abundant. The cultures were variably sensitive to most of the antibiotics used and resistant to Aztreonam. Conclusions: Human beings, as well as environmental objects, are likely to be a source of S. paucimobilis. Among the antimicrobials of choice for empirical antibiotic therapy, the best ones are the clavulanic acid-protected β-lactam antibiotics, Piperacillin Tazo-bactam, Carbopenems, and Rifampicin.
