摘要:

A 3‐year‐old female Petit Basset Griffon Vendeen is presented with tenesmus alvi caused by a 15 cm long chronic regional cicatrising eosinophilic coloproctitis with bacterial masses surrounded by clubs, resembling actinomycosis. Similar changes were found in the caecum, next to a nodular eosinophilic inflammation in the ileal mucosa.

摘要:

An oral high dosage regimen of sulphadimethoxine (SDM) was examined in pigs. The dose (50 mg/kg) in the therapeutic range, showed nonlinear pharmacokinetics, and administered by drench once a day for 4 days. The unbound plasma concentration‐time profile was compared with that of the dosage regimen based on nonlinear pharmacokinetics, where a pharmacokinetic model and parameters were used except for the first order absorption rate constant (ka) and bioavailability (F). F and ka were obtained from oral and intravenous administration of 20 and 10 mg/kg of SDM. The unbound plasma concentration was observed almost within the setting range by the dosage regimen through the experimental period. This result suggested that the dosage regimen, based on the nonlinear pharmacokinetic model, resulted in an appropriate effect in the clinical use.

摘要:

An enzyme‐linked immunosorbent assay (ELISA) system was developed for the detection of canine parvovirus (CPV) or CPV antigen in dog faeces and two other ELISA systems were developed for the detection of CPV‐specific antibodies in dog sera. The ELISA's were based on the use of CPV‐specific mouse monoclonal antibodies, which recognise different epitopes of the haemagglutinin of CPV and which also neutralise the virus. A double antibody sandwich (DAS) ELISA for the detection of CPV in dog faeces was compared with the haemagglutination (HA) test. The DAS‐ELISA proved to be more specific, sensitive and easier to perform than the HA assay. An indirect ELISA and a competitive ELISA for the detection of CPV‐specific antibodies in dog sera were compared with the haemagglutination inhibition (HI) test.

摘要:

Skin reaction patterns to the intradermal injection of a whole‐body flea extract were examined in five physically healthy dogs and in 24 dogs with German Shepherd dog Pyoderma (GSP) at 15 and 30 minutes and at 1, 2, 4, 8, 24, 48 and 72 hours after the injection. In 10 out of 24 GSP dogs a positive skin reaction was observed macroscopically after 15 minutes. Delayed reactions at 24 or 48 hours were not observed. In the control group neither immediate nor delayed reactions were observed.

摘要:

Skin reaction patterns to intradermal injections of a Staphylococcus intermedius antigen were examined in physically healthy dogs and in dogs with German Shepherd dog Pyoderma (GSP) at 15 and 30 minutes and at 1, 2, 4, 6, 8, 24, 48 and 72 hours after the injection. In both groups the skin histopathology revealed an aspecific inflammatory response of an early polymorphonuclear reaction, followed by a mononuclear cell reaction at 24 and 48 hours. It is concluded that hyper sensitivity to staphylococcal antigens does not play a role in the pathogenesis of GSP.

摘要:

The enzyme‐linked immunosorbent assay (ELISA) was evaluated for the diagnosis of naturally acquiredFasciola giganticainfection in cattle in comparison with conventional parasitological techniques. Using unfractionated whole worm extract of F. gigantica as the antigen, it was observed that there was a good correlation between ELISA positivity and positive diagnosis of fascioliasis by post mortem liver examination, bile egg sedimentation and faecal egg sedimentation. There was, however, a disparity between ELISA results and faecal egg flotation results.

摘要:

Cowdriosis and anaplasmosis are most important tick‐borne rickettsial diseases of ruminants. After a short introduction, in particular of their aetiology, epidemiology and diagnosis, present methods and future prospects for their control are briefly reviewed. The value and disadvantages of the four possible approaches, chemotherapy, tick control, the utilisation of inverse age‐resistance in order to attain endemic stability, and artificial immunisation, are reviewed. Promising future developments in the field of immunisation are indicated.

摘要:

Three horses with different and unusual types of inguinal herniation outside the vaginal cavity are described in detail. Attention is paid to the differences between these conditions and the more commonly occurring inguinal herniation inside the vaginal cavity.

摘要:

Three SPF‐laying hens were inoculated into the crop with avian intestinal spirochaetes which previously had been passaged in broiler chicks by oral inoculation (isolate 1380). Mild persisting gastrointestinal disorder developed; at nine months post inoculation spirochaetes were readily demonstrated in caecal faeces.

摘要:

Rapid and complete postmortal degradation of furazolidone and furaltadone occurred in liver, kidney and muscle tissues of veal calves. Different degradation half‐lives were observed between these tissues, the mean ranging from less than 7 minutes to 63 minutes. At 24 h after slaughter the parent nitrofurans were no longer detectable in edible tissues. For residue monitoring purposes plasma and/or urine can be used, if these matrices are treated in a specific way immediately after slaughter; muscle tissues and organs are unsuitable for residue monitoring of parent nitrofurans.
