Cilj. Piogeni streptokok je jedan od najčešćih i najozbiljnijih bakterijskih uzročnika infekcija ždrela kod čoveka. Zahteva antibiotsko lečenje, najčešće preparatima penicilina. U slučaju potrebe za primenom drugih antibiotika (alergije) najviše se koriste makrolidi (eritromicin). Senzitivnost ove bakterije na eritromicin je visoka, ali je rezistencija u porastu. Cilj rada je da utvrdi kolika je rezistencija piogenog streptokoka na terapiju eritromicinom, u Kraljevu, tokom 2011. godine.Metode. Kao izvor podataka korišćena je baza podataka službe za kliničku mikrobiologiju Zavoda za javno zdravlje Kraljevo za 2011.godinu. Podaci su obrađeni metodom deskriptivne statistike, a za obradu je korišćen kompjuterski program.Rezultati. Tokom 2011. godine na teritoriji grada Kraljeva ukupno je pregledano 5040 uzoraka brisa ždrela odraslih osoba. Od toga je u 4885 uzoraka pronađena fiziološka flora (96,9%), 155 uzoraka je sa patološkim nalazom. Kod 46 pacijenata (0,9% od svih pregledanih, 29,7% od onih gde je izolovana neka bakterijska infekcija) je izolovan piogeni streptokok. Kod 40 nalaza sa piogenim streptokokom je ispitivana osetljivost na eritromicin, senzitivnost je postojala u 28 slučajeva, intermedijaran rezultat je dobijen u 6 slučajeva, a rezistencija na eritromicin u 6 slučajeva (15%).Zaključak. Eritromicin je efikasan lek u terapiji infekcija izazvanih β-hemolitičkim streptokokom iz grupe A. Jedan je od prvih izbora u lečenju ovih infekcija kada je neophodno umesto penicilina dati neki drugi antibiotik. Nekontrolisanim davanjem ovog makrolida rezistentnost piogenog streptokoka na njegovo dejstvo se značajno povećava, te je njegova restriktivna i ciljana primena imperativ u budućem lečenju.Ključne reči: Streptococcus pyogenes; testovi mikrobiološke senzitivnosti; postupak sa uzorkom; eritromicin; javno zdravlje. ORIGINALNI RAD / ORIGINAL ARTICLE ABSTRACTObjective. Streptococcus pyogenes is one of the most common and most severe cause of bacterial infections of the throat in humans. It requires antibiotic therapy, usually penicillin preparations. In case of need of using other antibiotics (due to allergies), macrolides (erythromycin) are most commonly used. The sensitivity of these bacteria to erythromycin is high, but the resistance to it is growing. Aim of the study was determination of level of resistance of Streptococcus pyogenes to erythromycin in Kraljevo, during 2011.Methods. The database of the department of clinical microbiology of Public Health Institute in Kraljevo was used as a source of data collected in 2011. Data were analyzed using the method of descriptive statistics, and computer program as tool for this analysis.Results. During 2011, on the territory of the city of Kraljevo 5040 samples of throat swab taken from adults were analyzed. In 4885 samples physiological flora was found (96.9%), and 155 samples were with pathological findings. In 46 patients streptococcus pyogenes was isolated (that is 0.9% of all surveyed, and 29.7% of those where some type of a bacterial infection was isolated). In ...
