title: [Contamination of fish by agents of botulism type F and differentiating it from type E].
abstract: A total of 1859 samples of fish and various sea animals were examined for contamination with causative agent of botulism. The cultural fluid of 4--5-day cultures of the samples was tested in the reaction of neutralization with the diagnostic antitoxic antibotulin sera. types A, B, C, E. The causative agents of botulism (types A--7,B--16, C--5, E--128) were revealed in 156 samples. The sera were diluted to the concentration of 1 IU/ml for differentiation of the toxins types B and F in the neutralization test. Of 128 samples which gave a positive reaction with the serum of type E, 75 were identified as type F. In connection with the aforesaid the authors recommended in all the cases of botulism of type E in man to carry out differential diagnosis between the causative agents of botulism of types E and F and, on the basis of these data, to solve the problem on the necessity of production of therapeutic antibotulin serum of type F.
