Objectives: The incidence of group A beta hemolytic
streptococci (GABHS) in upper respiratory tract infections
in Erzurum was investigated.
Patients and Methods: In this descriptive study throat
swabs were obtained from 4112 patients (1989 males,
2123 females; mean age 21±1.5 years; range 14 to 46
years) with upper respiratory tract infections in Erzurum,
Turkey between January 2006 and December 2006
and they were cultured for isolation of GABHS.
Results: In this study GABHS were isolated in 268
(6.51%) of patients. Group A beta hemolytic streptococci
were isolated in 51 of 941 patients (5.42%) in the spring,
in 23 of 592 patients (3.88%) in the summer, in 69 of
968 patients (7.13%) in the autumn, and in 125 of 1611
patients in the winter. Of those patients in whom GABHS
were isolated, 128 (6.43%) were male and 140 (6.59%)
were female. At Chi square test, (Range for alpha value,
p=0.01 and p=0.05) there was a significant difference in
the frequency of infection between the seasons (p<0.01).
There was no significant difference between men and
women with respect to carrier rate (p>0.05).
Conclusion: The incidence of GABHS detected in
Erzurum was lower than that in other countries. There
were statistically significant differences in frequency
between the seasons (p<0.01). The highest incidence
was in the winter. Low incidence of GABHS in this region
may be due to prevention of the colonization because of
geographic features, nutritional habits and other factors.
