Respiratory tract infections are often caused by a lot of pathogens, which have to overcome host defences; they can be viral, bacterial or fungal infections. Some of pathogens adhere to mucosal epithelial cells or produce enzymes to destroy specific tissue. Upper respiratory tract infections are usually mild infections, but lower respiratory tract infections can determine significant morbidity, even mortality. The aim of this paper was establish the incidence and antibiotic resistance of bacterial pathogens involved in upper respiratory tract infections in 2016 - 2017 in Arges population. Were investigated 539 subjects and the antibiogram was performed for bacterial strains isolated from nasopharyngeal cavity. The most frequent bacteria were S. aureus and 20% from all strains were resistant to methicilline. The next pathogen,  Str. pyogenes, was sensitive to penicillin and Str. pneumoniae strains were sensitive to all tested drugs. The staphylococcal and streptococcal infections were more frequent in man than in women, for children under 15 years and adults over 50 years. The main concern of medical world and entire population regarding the causes of respiratory tract infection still is the staphylococcus and its antibiotic resistance, but the streptococcal infections are important, too.
