ABSTRACT
Introduction:
The air we breathe is the site of periodic occurrence of bacteria. One of the sources of bioaerosol is the gut microbiome. More and more frequently, microbes acquire resistance to antibiotics and can become a potential cause of infections. In recent years, this phenomenon is noticeable mainly in the health care facilities
Material and Methods:
Air samples were collected from five pharmacies located in Bydgoszcz. The impact method was used. The taxonomic analysis of culturable b-hemolytic bacterial strains was prepared using BIOLOG® technology. The susceptibility of identified staphylococci was assessed with the disc-diffusion method, in line with the recommendations of the EUCAST.
Results:
The results showed that the highest average number of b-hemolytic bacteria was identified at a sampling site located directly in the hospital. Identification of b-hemolytic bacteria showed that the examined strains mostly represented Bacillus and Staphylococcus genera. Based on the antibiogram, it was found that staphylococci strains showed the lowest sensitivity to penicillin, tetracycline, and erythromycin.
Conclusions:
The obtained results indicate that the air in pharmacies can be a source of potential pathogenic bacteria and antibiotic-resistant bacteria.
