respiratory syncytial virus infection in immunocompromised patients, especially those with defects in cell mediated immunity is associated with high morbidity and mortality. lymphocytopenia is an important factor associated with progression of upper to lower respiratory tract infection. the only licensed antiviral treatment for rsv available currently is ribavirin, although additional immunomod...

In troduc tion For a better understanding of the pathogenic mechanismof infectious diseases it is important to know the molecular basis of how the host responds to microbial pathogens and eliminates them. Recent advances in immunology and molecular biology have led to the discovery of a large number of cytokines and cell surface molecules, which allows us to understand such pathogenic mechanism...

Cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. Microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. The bacterial colonies were seen around the parabronchial spaces of the lung tissue. I...

according to statistical data from who, respiratory tract infections are among the most important health problems all over the world. differentiating viral from other causes of respiratory infections is difficult, but a good knowledge of viral etiologic factors can guide the physicians in the diagnosis and treatment of the disease. we carried out this descriptive, case-series study to evaluate ...
