New approach needed for diagnosis of human brucellosis in Morocco

Abstract

Human brucellosis is an infectious disease, caused by different species of the genus Brucella. It is a mandatory notifiable disease in most countries, including Morocco, and thus requires special vigilance on the part of health agencies. Prevention of this disease is based on surveillance and prevention of risk factors. Its management is based on serological or other diagnostic tests. The National Laboratory of Epidemic Diseases received 17 blood samples of human origin for notified cases of brucellosis in a region of southern Morocco. Biological confirmation of these samples was performed by Rose Bengal test and ELISA IgM test. The results showed a positivity rate of 88% proving the important role of serological tests in the diagnosis of brucellosis. Other rapid and efficient techniques are becoming essential for the confirmation of cases, taking into account the advanced biosafety procedures for these highly infectious pathogens.
