Abstract
Background: Brucellosis, especially if caused by Brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. In Iran, brucellosis was first recognized in 1932 and control of small ruminant brucellosis began in 1963. The aim of this study is to give an overview of the National Sheep and Goat Brucellosis Control Program in Iran.
Materials and Methods: In this cross-sectional study, data were collected from Iran Veterinary Organization over a period of 45 years. The national control program was based on kid and lamb vaccination and testing and slaughtering infected animals.
Results: B.melitensis biotype I in sheep, goat, and man was the predominant local infective biotype. This disease was reported in sheep, goat, cattle, horse, camel, and human. In addition, the prevalence of small ruminant brucellosis was estimated around 2.1%.
Conclusion: Prevention of brucellosis is dependent upon increasing public awareness of ranchers through health education programs and more active co-operation between health and veterinary medicine organizations as well as animal movement control in the borders.

Abstract
Background: In recent decades, with the increasing use of devices generating electromagnetic fields in modern industrial societies, the study of biological effect of these waves on the many organisms development has been considered by government and scientific organizations all over the world. Many people in all hours of their life are exposed to boarding electromagnetic fields of devices in their life and work places, with different intensities and frequencies. This presence of a significant relationship between the increase of some diseases and genetic aberrations and electromagnetic fields is one of the most important issues for researchers that has created many concerns regarding the adverse effects of electromagnetic fields. The findings of some studies indicate that this field does not have enough energy to damage biological molecules, while other researchers believe that electromagnetic fields by affecting cellular stress response and other protective mechanisms cause genetic cell damage. Some studies express that the electromagnetic field are safe alone, but they enhance the genotoxic function of physical and chemical environmental pollutants.
