Household transmission of Streptococcus pneumoniae among siblings with acute otitis media.

بررسی فراونی و الگوی مقاومت ناشی از استرپتوکوکوس پنومونیه در عفونت های حاد گوش میانی

Background and purpose: Acute otitis media (AOM) remains a frequent global infection of childhood, with up to 80% of children having at least one episode by three years of age. Ten to 30% have recurrent episodes, and 2–25% will have persistent middle ear effusion extending beyond three months. This study was conducted to determine the prevalence of Streptococcus pneumoniae in patients with acut...

Multiple Streptococcus pneumoniae serotypes in aural discharge samples from children with acute otitis media with spontaneous otorrhea.

Among 55 children with cultures positive for acute otitis media with spontaneous otorrhea, 28 (51%) had cultures positive for aural Streptococcus pneumoniae, and in 10 of these, two distinct strains were detected, in which 5 had pairs of strains that were both capsule-bearing serotypes. Such cases were more likely to have cultures positive for other otopathogens than those with only one pneumoc...

MUCOSAL ANTIBODIES TO PROTEIN AND CAPSULAR POLYSACCHARIDE ANTIGENS OF STREPTOCOCCUS PNEUMONIAE IN CHILDREN Relation to pneumococcal carriage and acute otitis media

Pneumococcal conjugate vaccine does not influence Staphylococcus aureus carriage in young children with acute otitis media.

We investigated nasopharyngeal carriage of Streptococcus pneumoniae and Staphylococcus aureus among infants and young children with acute otitis media in a country where use of 7-valent pneumococcal conjugate vaccine (PCV7) has been progressively implemented. Among 1783 children enrolled, 60.8% carried S. pneumoniae, and 9% carried S. aureus. Among S. pneumoniae carriers, the rate of S. aureus ...

Eradication of Streptococcus pneumoniae in the nasopharyngeal flora of children with acute otitis media after amoxicillin-clavulanate therapy.

Nasopharyngeal cultures were obtained from 60 children with acute otitis media before and after treatment with either 45 or 90 mg of amoxicillin (given as amoxicillin-clavulanate) per kg of body weight per day for 10 days. The number of Streptococcus pneumoniae isolates in the 45-mg/kg group was reduced from 12 to 6 and was reduced from 14 to 1 (P = 0.0261) in the 90-mg/kg group.
