The susceptibility of children to coronavirus disease-19 (COVID-19) and transmission of COVID-19 from children to others is a relatively unexplored area. The aim of this study was to understand the transmission dynamics of Severe Acute Respiratory Syndrome Coronavirus 2 in children. This was a retrospective observational study where a total of 19 paediatric index cases (including a set of twins) with COVID-19 and 42 primary contacts (adults—36, paediatric—6) from the immediate family members were included. All the index cases and four of the five positive contacts were asymptomatic. Despite adults staying with positive children in the same vehicle, same room in the quarantine centre and the same ward, only four of the parents became positive.
Background and Objectives: Streptococcus pyogenes is recognized as an important pathogen of respiratory tract infections. The rapidly, emerging problem of antibiotic resistant Streptococcus pyogenes is a major issue nowadays. The present study aimed to evaluate the antibiotic susceptibility of Streptococcus pyogenes isolated from upper respiratory tract infections in tertiary care hospital of south Karnataka.
Materials and Methods: A retrospective study was conducted over a period of two years. The specimens were processed by Gram staining and aerobic culture. The bacteria were isolated as per standard protocols. The minimum inhibitory values and extent of antibiotic resistance of commonly used antimicrobials were analysed for the isolated strains.
Results: A total of 2123 specimens were received from patients with respiratory tract infections, among which, 50 Strep- tococcus pyogenes isolates were obtained. Out of these, 8% were not sensitive to penicillin. Using VITEK 2 system, the prevalence of resistances to cefotaxime, erythromycin, tetracycline, levofloxacin, clindamycin and ceftriaxone were 4.2%,
83%, 51%, 8.9%, 40% and 5.3% respectively.
Conclusion: It is important to know about the prevalence of resistance and rising MIC values of commonly used antibiotics regarding Streptococcus pyogenes to avoid therapeutic failures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
