Vaccination against Flavobacterium psychrophilum in rainbow trout
Injection vaccines are not commonly used in fish. Is the recently tested injection vaccine against Flavobacterium psychrophilum in rainbow trout really an effective alternativecompared with the `classic` vaccine? It is, as this very interesting study shows.

Efficacy of mineral oil-based experimental injection vaccines against Flavobacterium psychrophilum were tested in rainbow trout, Oncorhynchus mykiss (Walbaum), under laboratory and field conditions.

The vaccines consisted of formalin- or heat-inactivated whole bacterium cell preparations of two different serotypes (Fd and Th) or a combination of serologically different F. psychrophilum (Fd and/or Th and/or FpT;Th).

Specific antibody responses against the bacterium in plasma and skin mucus were evaluated post-vaccination with enzyme-linked immunosorbent assay.

Efficacy of the vaccinations was determined by challenge trials to F. psychrophilum with the vaccinated rainbow trout.

Significantly higher antibody levels in plasma were detected in vaccinated fish compared with mock-vaccinated fish.

Injection vaccination did not trigger specific antibody production in the skin mucus. Significantly higher survival of i.p. vaccinated fish compared with non-vaccinated fish was observed during the challenge.

The results suggest that mineral oil-based injectable vaccines containing formalin- or heat-inactivated virulent cells of F. psychrophilum effectively triggered specific antibody production and protected the fish against bacterial cold water disease.

SMALL ANIMAL PRACTICE

Patient-specific facemask to facilitate brain biopsymembers
The objective of this pilot study was to describe the application and first preliminary data of a novel MRI and CT compatible patient-specific facemask for stereotactic brain biopsy of intracranial lesions in dogs. Five client-owned dogs presenting for neurological deficits consistent with forebrain disease were included in the study. All dogs had MRI findings consistent with an intracranial lesion. But biopsies in this region are not easy to obtain. Does an individual face mask help?
