Resumo:
Pharyngotonsillitis characterized by colonization of the tonsils by a range of microorganisms. There is a constant medical concern due to infections caused by Streptococcus pyogenes a group A β-hemolytic bactéria Lancefield (GABHS), which is potentially capable of causing complications in vital organs such as the heart and kidneys. In this work, we carried out the patients of oropharyngeal secretion culture of Nossa Senhora das Merces Hospital and students of the School Tancredo Neves, both in the city of Cuité-PB, from July 2013 to August 2014, with the objective of investigate the presence of S. pyogenes. Samples collected eighty volunteers were inoculated on sheep blood agar plate (5%), Mannitol and McConkey. Colonies with complete hemolysis would be evaluated for Gram stain, catalase production and sensitivity to bacitracin in the latter case when the strains were catalase negative. A total of eighty (80) met volunteers, thirteen (17%) samples showed beta-hemolysis, all were positive catalase, which showed no S. pyogenes in volunteers. This can be justified because factors such as the age of the people subjected to analysis, the possible failure on the use of antibiotics, the climatic conditions of the region and / or other causative agents of disease in cases of pharyngitis.
