Annotation:

Objective. The wide spread of nasopharyngeal carriage of Streptococcus pneumoniae among the population largely determines the epidemiological situation of pneumococcal infections.
Methods. 65 foci of pneumococcal bacteria and 157 members of their families were examined in April–December, 2017. Nasopharyngeal swabs from 222 people were examined by a classical bacteriological method. Identification and determination of the sensitivity of pathogens to antibiotics were carried out by conventional methods and in the bacteriological analyzer Vitek.
Results. Pneumococci were isolated in 16 out of 65 foci (24.6 %). When examining 31 foci, which included contact children and adults, pneumococci were isolated in 47.7 % of cases. When examining 34 foci, which included only contact adults, pneumococci were isolated in 5.9 % of cases. When 157 people from a family environment were examined, 65 S. pneumoniae bacteriostenes from mothers were sown in 6.7 %, from fathers in 4 %, from siblings in 42.9 % of cases. In total, pneumococcus were isolated in 21 people (13.4 % of cases) of the 157 family members, among which only two children received specific prophylaxis.
Conclusions. More than ten percent of their families are infected in the foci of nasopharyngeal carriers of pneumococci. With the greatest frequency, infection is detected in siblings. The risk of infection increases in foci, which include children.
