Durante 12 meses se estudian las infecciones otorrinolaringológicas en dos hospitales de Lima, tanto en niños como en adultos, con especial énfasis en Moraxella catarrhalis. Se tomaron 318 muestras de igual número de pacientes, de los cuales el 40% resultó negativo a bacterias patógenas. Del 60% restante se identificó staphylococcus aureus como el causante del 31% de las infecciones, seguido de Streptococcus pneumoniae colt el 19%, hieto Moraxella catarrhalis colt 16% y en cuarto lugar Haemophilus influenzae colt 10%. Rinorrea purulenta fue el principal síntoma en todos los casos. Streptococcus pneumoniae, Moraxella catarrhalis y Haemophilus influenza se aislaron mayoritariamente en niños menores de 14 años. El 15% de los S. aureus fueron oxacilino-ressistentes, el 11% de S. pneumoniae fueron resistentes a la penicilina, el 70% de M. catarrhalis eran productoras de B-1actailiasay cl 5% de H. influenzae también producían lactamasa. Nuestros resultados permiten oriental-mayor el tratamiento antibiótico de las infecciones respiratorias altas.

Adenotonsillar Hypertrophy

We sought to investigate the prevalence of potentially pathogenic bacteria in secretions and tonsillar tissues of children with chronic adenotonsillitis hypertrophy compared to controls. Prospective case-control study comparing patients between 2 and 12 years old who underwent adenotonsillectomy due to chronic adenotonsillar hypertrophy to children without disease. We compared detection of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Pseudomonas aeruginosa, and Moraxella catarrhalis by real-time PCR in palatine tonsils, adenoids, and nasopharyngeal washes obtained from 37 children with and 14 without adenotonsillar hypertrophy. We found high frequency (>50%) of Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis, and Pseudomonas aeruginosa in both groups of patients. Although different sampling sites can be infected with more than one bacterium and some bacteria can be detected in different tissues in the same patient, adenoids, palatine tonsils, and nasopharyngeal washes were not uniformly infected by the same bacteria. Adenoids and palatine tonsils of patients with severe adenotonsillar hypertrophy had higher rates of bacterial coinfection. There was good correlation of detection of Moraxella catarrhalis in different sampling sites in patients with more severe tonsillar hypertrophy, suggesting that Moraxella catarrhalis may be associated with the development of more severe hypertrophy, that inflammatory conditions favor colonization by this agent. Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, and Moraxella catarrhalis are frequently detected in palatine tonsils, adenoids, and nasopharyngeal washes in children. Simultaneous detection of Moraxella catarrhalis in adenoids, palatine tonsils, and nasopharyngeal washes was correlated with more severe tonsillar hypertrophy.

The inflamed tonsils harbour numerous types of bacteria, alone or in combination with group A β-haemolytic streptococci (GABHS). The cohabitation of the tonsils by GABHS and certain other bacterial species may contribute to the inflammatory process and the failure of penicillin therapy. This study evaluated the recovery of Moraxella catarrhalis, Haemophilus influenzae, Staphylococcus aureus and Streptococcus pneumoniae in association with GABHS in healthy children and those with acute pharyngo-tonsillitis (APT). Pharyngo-tonsillar cultures were obtained from 548 children with APT and 866 healthy children. GABHS was recovered from 112 (20.4 %) children with APT. Of the 114 H. influenzae isolates, 32 were recovered in association with GABHS (29 % of all patients who had GABHS) and 82 were isolated without GABHS (19 %) (P=0.0267). Of the 69 M. catarrhalis isolates, 25 were recovered in association with GABHS (22 % of all patients who had GABHS) and 44 were isolated without GABHS (10 %) (P=0.0012). In contrast, there was no association between the isolation of GABHS and the recovery of Staph. aureus or Strep. pneumoniae. GABHS was recovered from 104 (12 %) healthy children. Of the 69 M. catarrhalis isolates, 24 were recovered in association with GABHS (23 % of all patients who had GABHS) and 80 were isolated without GABHS (10 %) (P=0.006). There was no association between the isolation of GABHS and the recovery of H. influenzae, Staph. aureus or Strep. pneumoniae. This study demonstrates an association between the recovery of GABHS and H. influenzae and M. catarrhalis from pharyngo-tonsillar cultures of patients with APT and M. catarrhalis from pharyngo-tonsillar cultures of healthy children.

Introduction: The causative agents of acute tonsillopharyngitis are viruses and bacterial flora. Treatment of acute pharyngitis is mainly local, which includes aerosols with antiseptics. Aim: Study of antimicrobial action of "Apicold oral spray" on clinical isolates of microorganisms Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans isolated from patients' oropharynx in patients. Material and methods: The effect of Apicold Oral Spray (manufactured by APIPHARMA doo) on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis, and Candida albicans in Ukrainian patients was studied. Antimicrobial activity was assessed after 5, 10 and 20 minutes of action of one dose of "Apicold oral spray" on microorganisms. Bactericidal and fungicidal action (inhibition of cell growth of microorganisms) is expressed as a percentage according to the control. Results and discussion: Apicold Oral Spray has a 100% antimicrobial effect after 5 minutes on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans (complete growth inhibition of all 5 clinical isolates after 20 minutes). Conclusion: "Apicold oral spray" has a high antimicrobial effect on clinical isolates of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis and Candida albicans, which is confirmed by 100% inhibition of the growth of all bacteria after 5 minutes

Nasopharyngeal carriage of potential pathogens was studied in 425 healthy 3- to 6-year-old children attending 16 day-care centres (DCCs) in nine Czech cities during the winter 2004–2005. The overall carriage of pathogens was 62·8% (Streptococcus pneumoniae, 38·1%; Haemophilus influenzae, 24·9%; Moraxella catarrhalis, 22·1%; Staphylococcus aureus, 16%). An age-related downward trend was observed for colonization with respiratory pathogens in contrast to Staph. aureus whose carriage was significantly higher among older children. The following serotypes of colonizing S. pneumoniae were the most predominant: 23F (20·6%), 6A (15·1%), 6B (12·7%), 18C (7·8%), 15B and 19F (6% each). The majority (94·3%) of H. influenzae isolates were non-typable; among capsulated isolates, serotype b was not found. Decreased susceptibility to penicillin was determined in 3% of pneumococci; 4·6% of H. influenzae strains and 85·1% of M. catarrhalis strains produced β-lactamase. As for non-β-lactam antibiotics, pneumococci resistant to trimethoprim–sulphamethoxazole were the most common (15·7%) among the attendees.
