Background & Objectives:
In Mediterranean countries, infection of Toscana virus is a public health problem during the summer season, related to sandflies activity; it may cause aseptic meningitis and mild meningoencephalitis. We investigated the presence of antibodies (IgG) against the Toscana virus in the sera of individuals living in the area of Yafran, Libya.
Methods:
During the period from December 2013 to February 2014, a total of 232 sera samples were collected from Yefran hospital. Demographic information of participants collected in a questionnaire; samples were analyzed by the serological method of enzyme-linked immunoassays specific for Toscana IgG antibodies.
Results:
Seroprevalence of IgG antibodies among samples was 25% (n = 232). Seroprevalence varied among genders, age groups. The differences were not statically significant.
Interpretation & Conclusion:
Our findings indicate and confirm local circulation of the Toscana virus. It also indicates that TOSV infection is neglected, and needs to be considered as one of the causes of meningitis or meningoencephalitis.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
