Antibiotic Resistance and Serotypes Distribution in Bulgarian Clinical Isolates During the Years of 2021-2024.

group B , GBS) is an important human and animal pathogen. In recent years, the number of streptococcal isolates resistant to antimicrobial agents has increased in many parts of the world. Various mechanisms of antimicrobial resistance and capsular serotypes of GBS with different geographical distributions can be found.

Phylogenetic Lineages and Diseases Associated with Isolates Recovered from Bulgarian Patients.

has been recognized as an important cause of upper respiratory tract and middle ear infections in children, as well as chronic obstructive pulmonary disease and chronic bronchitis in adults. We aim to study the clonal structure, antimicrobial resistance, and serotypes of strains recovered from patients of different ages. Nasopharyngeal swabs, middle ear fluid, and sputum samples were collected.

A Review of the Impact of Streptococcal Infections and Antimicrobial Resistance on Human Health.

, (GAS), and (GBS) are bacteria that can cause a range of infections, some of them life-threatening. This review examines the spread of antibiotic resistance and its mechanisms against antibiotics for streptococcal infections. Data on high-level penicillin-resistant invasive pneumococci have been found in Brazil (42.
