To the Editor—McCullers and colleagues [1] recently reported results of their studies of influenza and Streptococcus pneumoniae infection in ferrets. The findings documented that pneumococcal transmission was enhanced in ferrets previously infected with influenza: ferrets that were infected with pneumococci after—but not before—influenza infection developed lethal secondary pneumonias and other...
Otitis media is inflammation of the middle ear and tympanic membrane, which often occurs as a result an acute upper respiratory tract infection. Generally, it caused by viral infection that then complicated secondary bacterial However, initial may also be bacterial.Otitis very common in children there high rate spontaneous recovery. It has been suggested unavoidable illness childhood part natur...
Abstract Secondary Streptococcus pneumoniae (Spn) infection is commonly associated with increased hospitalization and death following seasonal influenza virus infection. The animal models of A (IAV) secondary Spn coinfection have described the morbidity mortality leading to several proposed mechanisms enhanced disease. Influenza B (IBV) causes 25% cases bacterial coinfection, yet little known a...
Influenza A represents a significant cause of morbidity and mortality worldwide. Bacterial complications of influenza A confer the greatest risk to patients. TH17 pathway inhibition has been implicated as a mechanism by which influenza A alters bacterial host defense. Here we show that preceding influenza causes persistent Staphylococcus aureus infection and suppression of TH17 pathway activati...
Interleukin-22 (IL-22) has redundant, protective, or pathogenic functions during autoimmune, inflammatory, and infectious diseases. Here, we addressed the potential role of IL-22 in host defense and pathogenesis during lethal and sublethal respiratory H3N2 influenza A virus (IAV) infection. We show that IL-22, as well as factors associated with its production, are expressed in the lung tissue d...
introduction: the purpose of this in vitro study was to compare the ability of triple antibiotic paste (tap) to calcium hydroxide (ch) in disinfecting dentinal tubules. material and methods: sixty root blocks were obtained from extracted single-rooted human teeth. the root canals were enlarged with gates-glidden drills up to size 3 and were contaminated with enterococcus. faecalis ( e. faecalis...
