This thesis analyzes streptococcal skin diseases in detail, focusing on their frequency, pathogenic mechanisms and potential complications that can significantly affect public health. In the introductory part, the thesis provides a comprehensive overview of the history of streptococci, their classification, and pathogenesis, with special reference to Streptococcus pyogenes. This bacterium is known for its ability to cause various forms of skin infections that can range from mild to life-threatening conditions. The thesis describes in detail the clinical picture of the disease caused by this pathogen, including symptoms and disease progression. The analysis is further deepened by an overview of diagnostic methods that are crucial for the timely recognition of streptococcal infections. Laboratory methods are described, including rapid streptococcal tests and swab cultures, which are essential for accurate diagnosis. Treatment of streptococcal skin diseases is also discussed, emphasizing the importance of properly selected antibiotic therapy and, in severe cases, the need for surgical intervention. Special emphasis is placed on antibiotic resistance, which is a growing problem in the treatment of these infections. The research part of the work is based on the analysis of knowledge and awareness about streptococcal skin diseases among undergraduate nursing students at the University North. The research results indicate mediocre to good knowledge among students, but also identify specific areas where additional education is needed. Based on the obtained data, the thesis proposes strategies for improving the curriculum and educational programs with the aim of increasing the efficiency of diagnostic and therapeutic procedures. The thesis emphasizes the necessity of continuous education and raising awareness about streptococcal infections, in order to improve timely diagnosis and treatment. Education of healthcare workers and the public is important for reducing the prevalence of these diseases and preventing serious complications, thus contributing to a better public health outcome.
