Frequency of detection of Staphylococcus aureus isolates in various clinical materials from patients with purulent-inflammatory diseases in non-infectious clinics

Aim of the study . To study the frequency of isolation of Staphylococcus aureus from clinical biomaterials of patients with purulent-inflammatory diseases for the period from 2018 to 2022 according to the microbiological laboratory of JSC «National Scientific Medical Center», Astana. Materials and methods . A prospective microbiological study of the microbial landscape isolated from clinical samples of inpatients with purulent-inflammatory processes was carried out. Isolation and identification of strains was carried out on the basis of the microbiological laboratory of JSC «National Scientific Medical Center», Astana. Results and discussion . According to the microbiological laboratory of JSC «National Scientific Medical Center», during the period of bacteriological studies of clinical materials from patients with purulent-inflammatory diseases of various localization and from other materials used in medical institutions, from 2018 to 2022, a total of 961 strains of Staphylococcus aureus were isolated. When studying the dynamics of growth or decrease in the number over the years, it can be noted that for all the periods of study, we noted the most significant increase in the release of the amount of Staphylococcus aureus only from samples taken from the throat – 57.4%. In second place in terms of the frequency of Staphylococcus aureus discharge is a wound – 15%, in third place urine – 6.13%, followed by a nasal smear – 3.64% and sputum – 2.49%, respectively. Conclusion . Thus, one of the dominant pathogens in purulent-inflammatory diseases is Staphylococcus aureus and the main clinical biomaterial according to the frequency of detection during bacteriological examination of patients taken from non-infectious clinics from 2018 to 2022, according to the microbiological laboratory of JSC «NSMC» there was a throat smear, which accounted for 57.4%, then wound – 15% and urine – 6.13%. In the remaining biomaterials, the detection of Staphylococcus aureus was insignificant
