A Study of Brucella Infection in Humans

Objective: Brucellosis is the most usual zoonotic disease around the world especially in the Middle East, Mediterranean and Indian sub-continent areas. This bacterium has ten species that Brucella melitensis among them recognized as the most important cause of human brucellosis. This infection transfer ways to human include of wounds, bacteria inhalation and consumption of septic dairy such as raw milk, cream and butter. Brucellosis as a systemic disease can involve more organs of patients that have symptoms such as fever, night sweating, and backache.

Materials and Methods: This research is a review study and conducted by reviewing of the literature, which is related to this issue and also visiting, PubMed, and other linked websites. Results: In human brucellosis domestic animals are the main natural reservoir of infection. Whenever incidence rate of this infection in domestic and wild animals is reduced on the other hand incidence rate in human also will reduce. Conclusion: Blood cultures, serological tests and molecular tests are common laboratory methods of this infection. Diminution of relapse and therapeutic failure rates are as most important aim, which is researcher’s regards
