“…The antimicrobials which bacteria were resistant to the isolated EBHGA samples were: Penicillin and Cefepime (54.54%), Ceftriaxone (45.45%), Clindamycin and Ampicillin (27.27%) and Vancomycin and Erythromycin %). Although the prevalence of EBHGA was relatively low in our study (4.80%), the values coincide with a study carried out by Maciel et al [6], in which from the 753 samples analyzed in asymptomatic children, only 6 presented positivity for the same pathogen of this study. In Spain, a similar work verified a prevalence of 6% in asymptomatic schoolchildren [13].…”

“…One of the main laboratorial characteristics this pathogen presents to be identified and classified is the ability to shatter completely red blood cells in 5% sheep blood culture, causing a transparency in the culture medium, which is called Beta-hemolytic [5]. Streptococcus pyogenic is important when compared to groups B, C and G, not only because it is the main etiological agent of streptococcal pharyngitis [6], but also because it causes suppurate complications such as, cervical adenitis, peritonsillar abscess, retropharyngeal or cervical abscess [7]. In addition, EBHGA is related to other diseases such as streptococcal toxic shock syndrome, necrotizing fasciitis, scarlet fever and skin infections [8].…”

Objective: This study aimed to determine the prevalence of Group A β-hemolytic streptococcus in oropharynx of asymptomatic children who attend a public school and also the sensitivity and resistance profile of these bacteria to antibiotics commonly tested Methods: It was used sterile swabs to collect samples from the orpharynx of asymptomatic children for the accomplishment of microbiological culture. These children should not be using any antibiotic. For the differentiation of samples between others beta hemolytic species, bacitracin and L-Pyrrolidonyl-β-Naphthylamide tests were performed. All Group A β-hemolytic streptococcus samples were submitted to antibiogram test to establish the sensitivity and resistance profile. Results:From the 229 samples analyzed the etiological agent of study was detected in 4.8%. Antibiogram test was made and despite of the high sensitivity observed, there were cases of intermediate and / or total resistance to the antibiotics tested: beta-lactams, microclines and cephalosporin of the 3rd and 4th generation. In addition, only one of the positive cases for the bacterium under study was sensitive to all antibiotics. Conclusion:These results are relevant considering that bacteria belonging to Group A Beta-hemolytic Streptococcus are one of the microorganisms of major clinical interest, mainly when diagnosed in children. Thus, in order to reduce bacterial resistance to antibiotics it is important to use these drugs rationally.

“…Sin embargo, es superior a la encontrada por otros autores en poblaciones similares [18][19][20] . Estos resultados son coherentes con la literatura en la que se menciona que en la población infantil, la tasa de portación de esta bacteria varía de 15 a 20 %; siendo más frecuente en niños entre 5-15 años 2,11,21 .…”

“…Los resultados de esta investigación, difieren de los encontrados por otros autores los cuales reportan que todas las cepas de S. pyogenes aisladas fueron sensibles a betalactamicos 6,10,12,22 . En cuanto a la resistencia a macrólidos y lincosamidas, los porcentajes reportados en este estudio son mayores a los encontrados en otras investigaciones 1,12,18,23 . La resistencia a estos antibióticos considerados de primera elección, tiene implicaciones en el pronóstico de infecciones por estas cepas 6,24 .…”

Determinar la frecuencia de portación faríngea de S. pyogenes y sus perfiles de sensibilidad a antibióticos en escolares de la ciudad de Cartagena. Estudio transversal analítico; la muestra estuvo conformada por 131 niños. Las cepas de Streptococcus pyogenes fueron identificadas por métodos convencionales. La sensibilidad a antibióticos fue determinada por el método de Kirby-Bauer. Se aplicó una encuesta para identificar condiciones de riesgo asociados a la portación nasal. De la población estudiada, el 19,8% fueron portadores de la bacteria. Se obtuvieron 26 aislamientos de Streptococcus pyogenes. Al evaluar la sensibilidad antimicrobiana, se encontró que fueron principalmente sensibles a Ceftriaxona y Eritromicina (84,6% para cada uno). El 23,1 % (6/26) de los aislamientos fueron resistentes a ampicilina. No se encontró asociación significativa entre el estado de portación y la presencia de factores de riesgo (p>0,05). Se encontraron cepas resistentes a los antibióticos considerados de primera elección para el tratamiento de infecciones por esta bacteria.Palabras clave: Streptococcus pyogenes; portador sano; faringe; preescolar; farmacorresistencia microbiana; factores de riesgo.

“…This species is also known as Group A beta-hemolytic streptococcus (GABHS). It is the main representative of the beta-hemolytic streptococci, which has shown a strong ability to adapt to a human host over time, acting as an important etiologic agent in a number of clinical 32 manifestations, predominately in the oropharynx , as well as non-suppurative sequelae, which are characterized by rheumatic fever and glomerulonephritis.…”
