摘要:

A review is presented of food‐borne parasitic infections. Parasitic infections with public health hazards both from conventional slaughter animals and from seafood (fish and shellfis) are discussed.

摘要:

On two occasions an anaplasm was isolated from sheep on the Dutch island of Ameland. The organism proved to be highly pathogenic for splenectomised sheep; a non‐splenectomised animal recovered spontaneously after the packed cell volume had decreased by 40%.

摘要:

Lymphoid leukosis (LL) was successfully controlled in a commercial basic breeding line of White Plymouth Rock chickens. The control method has been developed for breeder flocks and consists of three elements:-In the flock under study, homogenates of embryos from all eggs collected during a number of I4‐day periods are tested for the presence of LL viruses.-Only eggs from hens that have been shown not to shed virus in their eggs are used for the production of progeny. The offspring are reared in isolation during the first two months of life, at which time the age‐related resistance against tumour formation by LL viruses appears to be sufficiently developed.-The chickens are subsequently inoculated intramuscularly with LL viruses of subgroups A and B transferred to a conventional chicken house.

摘要:

The course of post‐mortem breakdown of glycogen and ATP in turkey pectoralis major muscle was markedly influenced by several ante‐ and peri‐mortem variables. Application of a proper stunning procedure was highly effective in preventing peri‐ and post‐mortem muscle stress reactions.

摘要:

Serum chloramphenicol concentrations were determined by microbiological and chemical assay methods in cows, ewes, and goats treated parenterally with seven different veterinary parenteral chloramphenicol products, including the water soluble sodium succinate ester of chloramphenicol and solutions of 20%, 25% and 50% of chloramphenicol base in various organic solvents. Serum drug concentrations were analyzed for the effect of product formulation differences, dosage, whether the drug was administered i.m. at a single body site or to two sites, and the method of assay, on the absorption from the injection site, peak drug levels, and the persistence in serum of effective concentrations of the drug i.e. 5 to 10 ug / ml. Although differences were observed among the 6 products containing chloramphenicol base in respect to absorption rate and peak serum drug levels, and although these differences significantly influenced the persistence of microbiologically‐active serum drug concentrations at the level of ≥ 10 μg / ml, they did not at the level of ≥5μg / ml.

摘要:

An enzyme linked immunosorbent assay (ELISA) for feline infectious peritonitis (FIP) virus serology is described. The assay is analogous to a previously developed indirect heterologous immunofluorescence test (IFT) in which transmissible gastroenteritis (TGE) viral antigen was used. Comparative testing of selected feline sera in both assays resulted in corresponding titers, which justifies the conclusion that the ELISA is a reliable test for the serology of FIP virus.
