This book discusses all aspects of pulmonary pathology, including different bacterial, viral, fungal, mycoplasma and protozoan pathogens, accompanied by illustrations that show macro- and histopathological changes. It also presents microbiological, epidemiological and clinical data, with a particular focus on pneumonias of different bacterial aetiologies, influenza, and other viral infections. Further, the book explores the importance of mixed infections, including those in the late stages of HIV infections and virus-bacterial pneumonias, as well as pathological changes in modern tuberculosis, lung granuloma, and respiratory tract inflammation in different age groups.
