“…In our study cohort, the GAS carrier rate was highest in school-age children with 8.3 %, a carrier rate similar to the GAS carrier rate of 8.6 and 9.7 % reported for healthy school children from Pemba, Ethiopia, and Nepal [7][8][9]. Our data thereby confirmed age as risk factor for GAS colonization with the highest GAS carriage rate in school children as reported before [10].…”

“…The study revealed an asymptomatic BHS pharyngeal carriage of 4.0% in which GCS had the highest carrier rate of 27.8% among the identified species. This is consistent with other studies worldwide which ranges from 2.5-35.5% although their subjects were of varying age [15][16][17]. The higher carrier rate of group C and G assumes importance clinically as they have been involved in human throat and other pyogenic infections as well as neonatal toxic shock syndrome, necrotizing fascitis and other invasive infections elsewhere [18,19].…”

Colonization of the upper respiratory tract of children by beta-haemolytic streptococci (BHS) is imperative in spreading the infection in households and in community settings. The present study was designed to investigate the prevalence of throat carriage of diverse antigenic groups of BHS and the influence of age on carrier rates in healthy children in Calabar. Throat swabs of 450 children's were taken randomly from some government and private elementary schools and were visually examined and collected for further investigations.. The swabs were cultured aerobically on goat blood agar. Antimicrobial sensitivity testing was carried out on all BHS isolates on Muller Hinton blood agar by using the Kirby-Bauer disc diffusion method after standardizing the inoculums with a 0.5 McFarland. A total of 18(4%) BHS pharyngeal carriers were detected. BHS belonging to four streptococcal groups were isolated, groups C, F and G. The fourth group was not identified by the available grouping kit (UID S). Group C streptococci (GCS) had the highest percentage carriage of 5/18(27.8%). Other groups were F 3/18(16.7%), G 2/18(11.2%) and the UID S 8/18(44.4%). Carrier rate increased as age group increased and peaked at age group 10-12 years 7(36.8%). The percentage of BHS pharyngeal carriage was higher in Government aided schools (6.7%) than in private schools (1.7%). The BHS were highly resistant to Penicillin and Ceftazidime with a resistivity rate of 94.7% while Augmentine showed the lowest resistivity rate of 15.8%. The study established a high carriage of diverse antigenic groups in the throat of children with age influencing the rate of carriage in this community. A throat carrier rate of 39% of GGS/GCS among 450 children from this population indicated the etiological importance of streptococcal pharyngitis in this population. Therefore, there is need for further studies to identify the specific serotype of the group C/G streptococci circulating in this community.

“…The overall asymptomatic pharyngeal carriage rate of S. pyogenes among school children was 12.2% which is higher than the reports in Ethiopia 9.7%(4), in Tunisia 9.0% (19), in Nigeria 10% (20), Pemba 8.6%(21), India 8.4% (12), and Mangalore 5%(7) and lower than the report of Ethiopia 16.9% 5 (4,11,21,24).…”

Objectives The aim of this study was to determine the asymptomatic pharyngeal carriage rate of S. pyogenes, antimicrobial pattern and related risk factors among school children in Hawassa, Southern Ethiopia. Results Out of 287school children’s screened, 35(12.2%) were colonized with S. pyogenes. The carriage rate was significantly associated with factors such as sex (Female p=0.013) occupational status of mother (p=0.002), lower income source (500-900ETB, 1000-1500ETB) (p=0.001, and p=0.042), history of hospitalization (p=0.00) and residence of the children (p=0.002). High level resistant to tetracycline and low level to Vancomycine were observed, while penicillin, Amoxicillin, Erythromycin, Chloramphenicol, and Ceftriaxone were found to be effective.
