Renal ultrastructural damage induced by chronic exposure to copper oxide nanomaterials: Electron microscopy study.

Copper oxide nanomaterials are used in many biomedical, agricultural, environmental, and industrial sectors with potential risk to human health and the environment. The present study was conducted to determine the renal ultrastructural damage caused by 25 nm CuO nanoparticles in renal tissues. Adult healthy male Wister Albino rats () were administered 35 intraperitoneal injections of CuO nanoparticles (2 mg/kg).

The , , and genes diversity among methicillin-resistant Strains from health-care workers and patients.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen that is frequently isolated in both hospital and community environments. MRSA is considered a major nosocomial pathogen that causes severe morbidity and mortality.

Materials And Methods: Two hundred and twenty-five nasal swabs were collected (100 from health-care workers and 125 from patients).

Viral and bacterial infections associated with camel (Camelus dromedarius) calf diarrhea in North Province, Saudi Arabia.

Diarrhea and deaths in new-born camel calves were noticed by veterinary investigators and pastoralist in Saudi Arabia to be very high. Hence, it is thought to be necessary to investigate this problem from the virological and bacteriological point of view. The role of pathogenic bacteria and viruses in six different towns of North Province (Al-Assafia, Arar, Domat Aljandal, Hail, Skaka and Khoa) in Saudi Arabia was studied.
