Abstract

Beta-hemolitički streptokoki (BHS) su skupina bakterija koja na krvnom agaru vrši potpunu hemolizu eritrocita te uzrokuju mnoge bolesti poput gnojne upale grle, šarlaha, impetiga ili apscesa mozga. Prema Lancefield klasifikaciji, tu spada grupa A koju predstavlja Streptococcus pyogenes, Streptococcus agalactiae iz grupe B, Streptococcus dysgalactiae ssp. equsimilis iz skupina C i G te skupina Streptococcus anginosus s nekoliko vrsta skupine F, A, C i G te oni netipabilni. Sve se vrste mogu pronaći u ždrijelu čovjeka, osim S. agalactiae. Asimptomatski nositelj (kliconoša) je osoba kod koje ne dolazi do vidljive pojave simptoma bolesti, ali može prenijeti uzročnika te bolesti na drugu osobu. Kod kliconoše postoji infekcija, ali ona je subkliničke slike, odnosno neprimjetna je. Kliconoštvo za BHS može se naći u nazofarinksu, orofarinksu ili perinealnoj regiji. Cilj ovog istraživanja bio je ispitati stavove i znanje studenata o problematici BHS te provjeriti može li edukacija i uzimanje briseva imati pozitivan učinak na isto. Napravljena je i epidemiološka slika ispitanika gdje je udio asimptomatskih nositelja beta-hemolitičkih streptokoka iznosio 11,58 %. Nadalje, rezultati su potvrdili da čak i kratka edukacija te uzimanje briseva imaju statistički značajan pozitivan učinak na poznavanje problematike beta-hemolitičkih streptokoka i kliconoštva. Nakon edukacije, uočena je i promjena stajališta ispitanika prema ovoj važnoj problematici javnog zdravstva.

Abstract (english)

Beta-hemolytic streptococci (BHS) are a group of bacteria that show complete hemolysis of erythrocytes on blood agar and cause many diseases such as pharyngitis, scarlet fever, impetigo and brain abscess. According to the Lancefield classification, this includes group A represented by Streptococcus pyogenes, Streptococcus agalactiae from group B, Streptococcus dysgalactiae ssp. equsimilis from groups C and G and group Streptococcus anginosus with several species of groups F, A, C and G and those incompatible. All species can be found in the human pharynx except S. agalactiae. An asymptomatic carrier is a person who does not show symptoms of the disease but can transmit the cause of the disease to another person. The carrier has an infection, but it is subclinical, i.e., it is imperceptible. BHS can be found in the nasopharynx, oropharynx, or perineal region. The aim of this research was to examine the attitudes and knowledge of students about BHS and to check whether education and swabs can have a positive effect on it. An epidemiological study of the subjects was also made, where the share of asymptomatic carriers of beta-hemolytic streptococci was 11.58%. Furthermore, the results confirmed that even a short education and swabbing have a statistically significant positive effect on knowledge of beta-hemolytic streptococci and asymptomatic carriers. After the education, a change of attitude towards this important issue of public health was noticed.
