Popis: Pharyngotonsillitis in children is widely treated with antibiotics.To examine tonsil surface and core microflora following elective adenotonsillectomy in children.Tonsils of 102 Trinidadian children were prospectively examined for surface and core bacteriological culture and identification between 2005-2006.Tonsils (360) yielded 800 isolates of Streptococcus spp. (51.3%), Staphylococcus spp. (42.3%) and Gram-negative genera (6.4%). Surface and core recovery of staphylococci and streptococci were similar (p0.05). More (p0.001) surfaces (82.2%) than cores (63.3%) grew Streptococcus spp.; alpha-haemolytic Streptococcus prevalence was higher (p0.001) than ss-haemolytic Streptococcus on surfaces (74.4% vs. 18.6%) than cores (58.9% vs. 13.7%). Surfaces and cores were not concordant for streptococci (p0.0004) and alpha-haemolytic Streptococcus (p0.007). Surface and core ss-haemolytic Streptococcus yield was higher (p0.05) in 6-16 than 1-5 year olds (31% and 23.8% vs 12.5% and 8%). S. pyogenes surface and core prevalence was (84.6% vs 70%) and (50.0% vs 25.0%) in older and younger children respectively. Klebsiella spp. (6.6 %, 2.2%), Proteus (4.4%, 4.4%) and Pseudomonas (4.4 %, 1.1%) grew on surfaces and cores respectively.Tonsil surfaces yield higher surface than core carriage for streptococci overall and for alpha haemolytic streptococci. Older children grow more beta-haemolytic streptococci and are high colonizers of S. pyogenes. Studies probing the mechanisms of streptococcal adhesions in Trinidadian children are suggested.
