Background.
Leptospirosis is an anthropozoonotic reemerging neglected infectious disease underreported in most developing countries.
A cross-sectional study was performed between 17 and 23 February 2014 to estimate the seroprevalence of leptospirosis among high-risk populations in Casablanca (Morocco).
Methods.
A total of 490 human serum samples (97.6% males) were collected in 3 high-risk occupational sites including the biggest meat slaughterhouse (n = 208), a poultry market (n = 121), and the fish market (n = 161).
A total of 125 human blood samples were also collected from the general population and used in this study as a control group.
To detect the presence of anti-Leptospira, sera were screened with in-house IgG and IgM enzyme-linked immunosorbent assay (ELISA).
Positive samples were tested by Microscopic Agglutination Technique (MAT) using a panel of 24 serovar cultures and cut point of 1 : 25.
Results.
Seroprevalence of leptospirosis among the control group was 10.4% (13/125).
A high seropositivity among the overall seroprevalence of 24.1% (118/490) was observed in the high-risk groups of which 7.3% (36/490), 13.7% (67/490), and 3.1% (15/490) were for anti-Leptospira IgM, IgG, and both IgG and IgM antibodies, respectively.
Most of the positive individuals were occupationally involved in poultry (37.2%), followed by the market fish (26.1%) and the meat slaughterhouse (14.9%) workers.
Among all ELISA-positive serum samples, 20.3% (n = 24) had positive MAT responses, of which the Icterohaemorrhagiae (n = 7) is the most common infecting serogroup followed by Javanica (4), Australis (2), and Sejroe, Mini, and Panama (one in each).
In the remaining 8 MAT-positive sera, MAT showed equal titers against more than one serogroup.
Conclusion.
Individuals engaged in risk activities are often exposed to leptospiral infection.
Therefore, control and prevention policies toward these populations are necessary.
