[Effect of Sulfakombin SPOFA on the dynamics of the extent of coccidiosis in small rabbit breeding operations].

We determined the yearly changes in coccidiosis extensity applying the results of an examination of 2707 rabbits performed in the years 1981-1984. A field trial was conducted to study the efficiency of the Czechoslovak anticoccidic drug Sulfakombin Spofa administered to control coccidiosis in small rabbit breedings. We made the calculations to find out the optimum time of administration of sulphonamide substances.

[Testing the protective effectiveness of vaccines against infection with Pseudomonas aeruginosa in mink (Lutreola vison)].

Infections by Pseudomonas aeruginosa have caused losses on mink farms in recent years, particularly with a clinical manifestation of haemorrhagic pneumonia. This paper includes the first results of the practical use of the Czechoslovak soluble monovaccine of polyvalent action in the treatment of mink infected by Pseudomonas aeruginosa. The action of the vaccine is based on the protective effect of Original Endotoxin Protein (OEP), antigen common to all species of the genus Pseudomonas.

[Vaccination of ferrets (Putorius furo) against rabies using a tissue vaccine].

The use of live tissue rabies vaccine from Vnukovo-32 strain produced by the Bioveta National Corporation at Ivanovice na Hané was tested on 15 ferrets (Putorius furo L. 1758). The 21st day after subcutaneous application of 3 ml of vaccine, the average titre of virus-neutralizing antibodies was 1 : 71.

[Encephalitozoonosis in farm-bred arctic blue foxes (Alopex lagopus)].

Occurrence of encephalitozoonosis in farm breeding of blue fox is described. Fifty youngs of eight breeding females were infected, mortality was 88%. The main clinical symptoms of the disease were somnolence, ataxia, vision disorders, clonic spasms, at a protracted course also retarded growth.
