Роль новых и забытых вирусов в этиологии гепатита.

ЦЕЛЬ ОБЗОРА: В настоящем обзоре мы представляем обзор новых и забытых вирусов, связанных с участием печени. ПОСЛЕДНИЕ НАРУШЕНИЯ: вирус гепатита Е (ГЭМ) появился за последние два десятилетия, вызывая гепатит во многих частях мира. Кроме того, было также отмечено участие печени в некоторых появляющихся арбовирусных инфекциях. Многие сообщения свидетельствуют о травмах печени, связанных с денге; однако чикунгунья, Западный Нил, энцефалит, переносимый тиками, и вирус Зика редко ассоциируются с клинически явным заболеванием печени. Кроме того, некоторые малоохваченные вирусы, такие, как аденовирусы

Mycoplasma Pneumoniae and Chlamydophila pneumoniae in hospitalized children with bronchiolitis.

Bronchiolitis is an acute lower respiratory tract infection in early childhood caused mainly by different viruses. Etiology of bronchiolitis have been studied in different environments and populations. Respiratory syncytial virus (RSV), human Metapneumovirus (hMPV), human Bocavirus (hBoV), human Rhinoviruses (hRV) have consistently been shown to predominate. Few studies however have attempted to determine whether other pathogens, particularly Mycoplasma Pneumoniae (MP) and Chlamydophila pneumoniae (CP), are associated with bronchiolitis in children under 2 years of age.
