Group A streptococcus or Streptococcus pyogenes is the most studied bacterium within the group of beta-hemolytic streptococci, since it causes 30% of pharyngitis, although in recent years group C beta-hemolytic streptococci and group G beta-hemolytic streptococci have gained importance.
group C beta-hemolytic streptococci and group G beta-hemolytic streptococci have gained importance in recent years. These bacteria can remain in individuals without causing symptoms.
In the present investigation, the frequency of asymptomatic streptococcal asymptomatic carriers of beta-hemolytic streptococci in military personnel of three military institutions in Maracay. institutions of Maracay. The distribution of antistreptolysin of antistreptolysin O titers, an antibody present in individuals in individuals who have been in contact with these bacteria. bacteria. A pharyngeal exudate was collected from each individual and a blood sample for the determination of antistreptolysin O was taken from each individual. Streptococci group G beta-hemolytic streptococci accounted for 46.30% of the isolates, followed by group G beta-hemolytic streptococci. of the isolates, followed by group C (27.78%), A (9.26%), B (9.26%) and F (7.40%). Titers lower than 200 IU/mL (negative) were represented by 49.1%, while 50.1% were negative. 49.1%, while 50.9% (positive) were represented by titers equal or titers equal to or higher than 200 IU/mL. It can be can be concluded that military personnel behave as asymptomatic carriers in a asymptomatic carriers in a significant percentage, This may be due to the condition of overcrowding in which they are located. in which they find themselves. There was a significant percentage (50.9%) of individuals positive for antistreptolysin O, indicating that these personnel have been in contact with Streptococcus pyogeneses. Streptococcus pyogenes, group C or E beta-hemolytic streptococci, group G beta-hemolytic streptococci, and group G beta-hemolytic streptococci. group G streptococci.
