Abstract

Objectives: To re-draw attention to the unnecessary prescribing of antibiotics. ----- Methods: We monitored nasopharyngeal colonization by 3 potentially pathogenic bacteria, Streptococcus pyogenes, Streptococcus pneumoniae, and Haemophilus influenzae type b in 81 children between the ages of 6 and 7 years who attended the same primary school. The children's health status was also monitored, without using antimicrobial treatment for healthy/asymptomatic carriers. Nasopharyngeal swabs were collected on 6 occasions during autumn months, from mid-September to mid-December 2016. The children who fell ill during the study were treated at the Ear, Nose and Throat Clinic, Sisters of Mercy University Hospital Center, Zagreb, Croatia. ----- Results: Four hundred and sixty-three nasopharyngeal swabs were collected. Each child had at least one positive swab result. Bacterial colonization with Streptococcus pyogenes had the highest colonization rate. During the study, 83% of the children were healthy/asymptomatic carriers with no clinical signs of disease, while 17% became ill. The statistical results showed that the increase in all examined bacteria was statistically significant. ----- Conclusions: Our study results showed that positive bacterial findings in nasopharyngeal swabs from clinically healthy carriers were not an indication for antibiotic therapy.
