Respiratory tract infection, Blood parameters, Electrical generators, Heavy metals


One of the most commonly health problems are Respiratory tract infections, almost (5-10) % of death cases reported in Centers for Disease Control and Prevention in the community and this increased over the years regardless of the country. As a substitute source of electricity many developing countries use electrical generators, but gases and materials rising from them will be inhaled from surrounding people especially for who work on them. This study aimed to detect and identify bacteria isolated from persons sputum suspected with Respiratory tract infections and collect blood to perform hematological, biochemical study and detection of some heavy metal for both workers and non-workers in electrical generators. Sputum samples were collected from electrical generators workers by 184 samples and from non-workers in electric generators by 50 samples, both were suspected had respiratory tract infection from the symptoms. All samples were cultured on blood agar and MacConkey and bacterial identification by utilizing a Vitek 2 system was done. Blood samples were also collected in order to perform biochemical, Hematological study and detection the level of some heavy metals in blood. Out of 184 samples, 27 samples (14.67 %) produced a significant growth of microbes, the predominant bacteria were Klebsiella spp. Statically, there were significant difference between workers and non-workers in Electrical generators at (p<0.05) for: Hematological parameters (WBC, Basophil and Eosinophil), all the liver enzymes, the Four heavy metals (Lead, Cadmium, Zinc and Copper). This study showed that Electrical generators had caused changes in blood parameters (WBC, Basophil and Eosinophil), all the liver enzymes and the Four heavy metals (Lead, Cadmium, Zinc and Copper). This effect most more studied and evaluated in generators workers.
