| PROTEKT (Prospective Resistant Organism Tracking and Epidemiology for the Ketolide Telithromycin) is a global surveillance study established in 1999 to monitor antibacterial resistance of respiratory tract organisms. Thirteen centers from Argentina, Brazil and Mexico participat ed during 1999-2000; they collected 1,806 isolates (Streptococcus pneumoniae 518, Haemophilus influenzae 520, Moraxella catarrhalis 140, Staphylococcus aureus 351, S. pyogenes 277). Overall, 218 (42.1%) of the S. pneumoniae isolates had reduced susceptibility to penicillin, 79 (15.3%) were penicillin-resistant and 79 (15.3%) were erythromycin-resistant. Mexico had the highest prevalence of penicillin (76.5%) and erythromycin (31.2%) resistance. Of 77 erythromycin-resistant S.... |

| La faringitis aguda bacteriana (FAB) representa entre un 20 a 30% de las faringitis. El principal agente causal es Streptococcus pyogenes. Se revisó retrospectivamente la información microbiológica disponible entre 2010 y 2016, para analizar la incidencia de la FAB, sus agentes causales, la incidencia de casos según el período estacional y rango etario. Se determinó el porcentaje de resistencia (R) de S. pyogenes a eritromicina y el fenotipo predominante. Se diagnosticó FAB en 21,5% de 3.246 cultivos, donde 89% fueron causados por S. pyogenes. El 35,3% de las FAB se presentó en niños de 7 a 10 años, seguido por el grupo de mayores de 15 años (31,3%). Se evidenció un aumento de faringitis por Streptococcus dysgalactiae subsp. equisimilis en 2011 y 2014;... |

| ABSTRACT >The in vitro antimicrobial activity of Gymnopetulum chinense (Cucurbitaceae), a lesser known climber of Eastern Ghats and recently recorded species from Odisha, India was studied against five selected human pathogenic bacteria (Streptococcus mutans, S. pyogenes, Vibrio cholerae, Shigella flexneri and Salmonella typhi), by agar well diffusion (AWD), disc diffusion (DD) and broth dilution methods. Different solvent extracts were prepared from the leaves of G. chinense using various solvents viz. n-hexane, chloroform, methanol, acetone and aqueous. The nomenclature, detailed description and photographs of the plant are provided to facilitate its easy identification. The leaf extract showed presence of phenolic compounds, tannin, saponin,... |
