The invention concerns an immunogenic composition comprising: i) an antigenic polypeptide consisting of a fragment of the protein histone H2B of Leishmania, said fragment including the N-terminal region of said protein histone H2B, and ii) an adjuvant stimulating the immune response. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. Additionally, the casing may be displaced by two separate casing supports coupled to two separate speaker supports and speakers. By providing such an alert, the present invention makes it very difficult to alter, for example, an identification card, an use it for unauthorized purposes. The communication system also includes at least one service site connected to the communication network. The two pole circuit breaker is so designed that both of the two poles of the circuit breaker trip simultaneously and open even when an undesired electrical condition exists on the portion of the power distribution unit electrically coupled to only one of the poles.
