An overview of rabies - History, epidemiology, control and possible elimination

  Rabies remains the most important zoonotic disease in many countries. Public concern and fears are most focused on dogs as the source of rabies infection to humans and other domestic animals. Several bat species are reservoir hosts of rabies and therefore can be a public health hazard. The possibility of a carrier state or asymptomatic form of rabies deserves serious evaluation. Rabies in most countries was...

Malondialdehyde, vitamin E, and anti-oxidant enzyme activity levels in patients with crimean-congo hemorrhagic fever

  Crimean-congo hemorrhagic fever (CCHF) is a viral disease that can be seen in people epidemically or as single patient. CCHF is a highly deadly disease caused by Nairovirus from Bunyaviridae family. Endothelial damage caused by secreted cytokines plays an important role in the pathophysiology of the disease. Reactive oxygen species (ROS) are highly cytotoxic. Intracellular and extracellular...

Isolation and application of a chlorpyrifos-degrading Bacillus licheniformis ZHU-1

  A strain ZHU-1 capable of utilizing chlorpyrifos as the sole carbon sources and energy was isolated from soil. ZHU-1 was identified as Bacillus licheniformis based on analysis of morphology, physiological and biochemical characters and 16S rRNA. The addition of ZHU-1 to soil treated with chlorpyrifos resulted in a higher degradation rate than noninoculated soils, the degradation rate of...
