Occupational bacterial infections

Some occupational bacterial infections are distributed worldwide, whereas others are nowadays limited to certain countries where prevention measures have not been applied. 

Chronic bronchitis is a result of several contributing factors, including cigarette smoking exposure to occupational dusts, fumes, and environmental pollution and bacterial (and possibly viral) infection. 

Silicosis, a form of pulmonary fibrosis, is the primary health problem resulting from inhalation exposure to particles of crystalline silica (SSDC, 1988 NIOSH, 2002 Castranova, 2000 Castranova and VaUyathan, 2000). Other diseases associated with occupational inhalation exposure to crystalline silica include lung cancer, chronic obstructive pulmonary disease, nonmalignant respiratory disease, auto-immune related diseases (such as rheumatioid arthritis), renal diseases, and (as a complication of silicosis) increased risk of bacterial or fungal infections such as tuberculosis. Skin granulomas or obstructive lymphopathies may result from dermal exposure and uptake of silica particles (NIOSH, 2002). 

Chronic bronchitis is a result of several contributing factors the most prominent of these are cigarette smoking and exposure to occupational dusts, fumes, environmental pollution, and bacterial (and possibly viral) infection. The hallmark of this disease is a chronic cough with resulting sputum production and the persistent presence of microorganisms in the patient s sputum.
