Hybridization in the wild between Tursiops truncatus (Montagu 1821) and Delphinus delphis (Linnaeus 1758).

A case of intergeneric hybridization in the wild between a female bottlenose dolphin (Tursiops truncatus) and a short-beaked common dolphin (Delphinus delphis), considered members of 'vulnerable' and 'endangered' subpopulations in the Mediterranean, respectively, by the International Union of Conservation of Nature is described in this paper. The birth of the hybrid was registered in the Bay of Algeciras (southern Spain) in August 2016, and the animal has been tracked on frequent trips aboard dolphin-watching platforms. This unique occurrence is the result of an apparent ongoing interaction (10 years) between a female bottlenose dolphin and common dolphins.

[What is next in antirabies immunization?].

The authors compare the geometrical means of titres of specific antirabic antibodies in a group of subjects immunized by the intradermal route with vaccine from a tissue culture of human diploid cell (Rabivac Behring, FRG) and in groups of subjects immunized by the subcutaneous route with the vaccine Vnukovo SAD-32 (USSR), using a short and long immunization pattern resp. The group with intradermal administration had higher geometrical mean values of antibody titres than the age-matched group immunized by the subcutaneous vaccine Vnukovo. The low mean titres and incidence of zero values of antirabic antibodies in age groups above 50 years is alarming.

[Intradermal method of vaccination with a human diploid cell tissue culture vaccine for preexposure antirabies immunization].

The authors provide evidence of seroconversion in 16 subjects (100%) following intradermal administration of antirabies vaccine from a tissue culture of human diploid cells [Rabivac, Behring, FRG] for the purpose of pre-exposure immunization. The immunomodulating preparation Levamisol [Decaris Richter, Hungary] did not influence the mean antibody titre during administration by the intradermal route.
