Nasopharyngeal microbiota in infants and changes during viral upper respiratory tract infection and acute otitis media
BACKGROUND Interferences between pathogenic bacteria and specific commensals are known. We determined the interactions between nasopharyngeal microbial pathogens and commensals during viral upper respiratory tract infection (URI) and acute otitis media (AOM) in infants. METHODS We analyzed 971 specimens collected monthly and during URI and AOM episodes from 139 infants. The 16S rRNA V4 gene r...
متن کاملAssociation of nasopharyngeal bacterial colonization during upper respiratory tract infection and the development of acute otitis media.
Acute otitis media occurs mostly after upper respiratory tract infection; the causative bacteria are those colonized in the nasopharynx. We studied 709 episodes of upper respiratory tract infection and found that children with no bacteria in the nasopharynx were at low risk for acute otitis media, whereas children with 3 pathogenic bacteria were at the greatest risk.
متن کاملUpper Respiratory Tract Infection
Upper respiratory tract infection (URI) is a general term for a heterogeneous group of illnesses caused by numerous etiologic agents that affect the mucosal lining of the upper respiratory tract, including the middle-ear cavity and paranasal sinuses. URIs are primarily caused by viruses, rhinoviruses being the most common etiological agents. Respiratory viruses transmit easily via direct contac...
متن کاملVagal neuropathy after upper respiratory infection: a viral etiology?
PURPOSE To describe a condition that occurs following an upper respiratory illness, which represents injury to various branches of the vagus nerve. Patients with this condition may present with breathy dysphonia, vocal fatigue, effortful phonation, odynophonia, cough, globus, and/or dysphagia, lasting long after resolution of the acute viral illness. The patterns of symptoms and findings in thi...
متن کاملIllness and otological changes during upper respiratory virus infection.
OBJECTIVES Upper respiratory virus infection is associated with the expression of symptoms and signs of illness, and with the development of complications in anatomically contiguous structures. In most epidemiological studies, the frequency of the various complications is expressed as a fraction of the total population judged to be ill by report, signs, or symptoms. Because not all infected sub...
