INTlIAPERITOIIW, VACCIIATION OF IIAMS

Sir. -A recent issue of the Animal Health Division's excellent publication Surveillance (1978 No.5 Spring), reported that the Palmerston North Animal Health Laboratory had encountered a case involving40 two-year-old rams, the majority ofwhich had intramuscular perirenal abscesses. It was reported that these abscesses were due to vaccination with a single dose of Br. ovis vaccine. administered by the intraperitoneal route. Approximately half of the report treated the reader to a dissertation on the authors views on the technique, which one can only assume are derived from ignorance of both the correct technique for intraperitoneal injections in sheep and the effectiveness of this type of administration. The following points relate to the comments made by the author of this report: I. The author comments that the intraperitoneal technique for the administration of Br. o viS vaccine is not approved by the Animal Remedies Board. Only the author would know from whence this remarkable statement came. Discussion with the Registrar of the Board clearly indicates that the ARB does not legislate on methods of administration. It also recognises that qualified and responsible veterinarians are capable of making sound decisions on drug and vaccine administration. 2. The report concludes. erroneously, that the intraperitoneal technique seems inferior to the doubJe subcutaneous method of administration. Work over a period of years has demonstrated indistinguishable titre patterns in rams vaccinated by the two teChniques. 3. The Central Hawkes Bay group have vaccinated approx­ imately 60.000 rams over the last 5 years, using the in­ traperitoneal method and have encountered no problems with abscess formation. Compare this with the unsightly lumps which are commonly seen on rams following double subcutaneous injection. This, coupled with other undesi­ rable side-effects. undoubtedly contributed to the ~iscon­ tinuance of ram vaccination by breeders and an upsurge in the incidence of ovine brucellosis. 4. Clearly. the occurrence of intramuscular abscesses in the reported case was due to poor technique. The method described by Kerry and Thomson (1969) and Quinlivan and Wallace (1975) requires the use of a short bevel 16-18 gauge ~ inch needle. Injection is made on the right hand side of the animal. at a point midway on a line from the stifle to the vertebral articulation of the last rib. This point is situated in the lower extremity of the sub-lumbar fossa. To achieve this correct positioning, the animal has to be sui­ tably restrained by an assistant. It must be concluded that, in this unfortunate instance. the operator must have erred in administration. References Anon (1978): SUfI'eillunct'5: 19. Kerf\'. J. R.: Thomson. A. O. (1969): Vel.
