“…In various studies from Sweden, the Netherlands, Italy, Spain, the United States and Belgium, mange prevalences from 20% to 86% were recorded (Flesjaˆand Ulvesaeter 1979;Hollanders and Vercruysse 1990;Gualandi et al 1994;Davies et al 1996;Gutie´rrez et al 1996;Alonso de Vega et al 1997;Melancon 1998;Smets and Vercruysse 2000). Sarcoptes infection in pigs causes cuticular lesions accompanied by strong pruritus which in turn results in constant uneasiness and drop of performance.…”

Two trials were carried out to compare the use of different enzyme-linked immunosorbent assays (ELISAs) for the detection of antibodies against Sarcoptes scabiei var. suis. In the first trial, we employed four tests and 70 selected sera from a closed pig farm with sarcoptic mange. The sera were taken from the breeding area as well as from the finishing unit and compared with skin scrapings. The SARCOPTES-ELISA 2001 yielded the most positive results (88.58%), followed by the ELISA of the National Veterinary Institute, Uppsala (70%), the Acar-Test P-ELISA (52.86%), skin scrapings (48.57%), and the CHEKIT Sarcoptest (30%). In the second trial, eight litters from infected sows were examined from weeks 1-12 of life using the CHEKIT Sarcoptest and the SARCOPTES-ELISA 2001. The presence of maternal antibodies was highest on day 7 in both ELISAs and could be detected until weeks 5-9 of life. Antibodies increased as a result of an active immune response between days 56 and 63 in the SARCOPTES-ELISA 2001 and between days 70 and 77 of life in the CHEKIT Sarcoptest. Significant differences between the first and second litters were observed.

“…The samples were considered positive at a cut off of 0.4 corrected optical density (ODr) for sera (Smets and Vercruysse, 2000), and of 0.5 ODr for the extracts of diaphragmatic muscle (Meet Juice-MJ) (Vercruysse et al, 2006). The statistical correlation between the results of the four tests was calculated with the Spearman_s Correlation Coefficient.…”

“…In our study, there was distinct difference in the rate at which S. scabiei spread in the three pens in which a seeder pig was placed. Ear scraping examinations indicated that in one pen, six out of 14 pigs were infected on day 28 of the experiment, while in the two other pens, only one S. scabiei mites are found predominantly on the face and in the ears of pigs (13,33), and of all conventional diagnostic methods to detect S. scabiei infection, examination of ear scrapings is the most sensitive (28). However, it is a question whether this method is sensitive enough to detect infection at any time during the infectious period.…”

,13). Such metastases seem to occur frequently, as seen in our postmortem material and from a preliminary retrospective study of carcinomas in the skin in cats, where many had the features of metastatic carcinomas of pulmonary origin (own data, not shown). Metastases of primary pulmonary carcinomas in digits and other organs have also been described in humans (2). The cat is the only domestic animal in which metastases of a primary pulmonary carcinoma in the digits have been described. The reason for this phenomenon is not known. A possible haematogenous spread of the tumour and the high vascularity of the digits in cats are mentioned as possible factors (5,15). In the primary pulmonary carcinomas in our cats, large arteries and veins were often invaded and in the metastases in the digits neoplastic aggregates were regularly seen within arteries. In only two of the 12 cats offered for postmortem examination were metastases of the pulmonary carcinomas found in the bronchial lymph nodes. Thus, feline pulmonary carcinomas seem to metastasize haematogenously rather than lymphogenously. In cats with malignant epithelial tumours in the digits, it is important to realize that most are digital metastases of pulmonary carcinomas, with a poor prognosis. So, in all cases with clinical suspicion of a tumour in a digit, thoracic radiographs should be made before surgery. Accepted for publication: November 2, 1999. SUMMARYReports on the effects of mange on the production performance of pigs are conflicting. So far, studies have used experimental infections, by depositing encrusted lesions from chronically infected pigs into the ears of experimental pigs. However, this is a poor representation of what happens under natural field conditions. The purpose of our study was to quantify the effects of sarcoptic mange on production performance and pruritus in pigs that were infected by contact with S. scabiei var. suis-infected pigs. A total of 80 piglets were matched by sex and weight and randomly divided between experimental and control compartments. In the experimental compartment, each of Animal Health Service, PO Box 4, 5280 AA Boxtel, the Netherlands.three naturally S. scabiei var. suis-infested pigs were randomly allocated to three pens with 13 susceptible pigs each. tal compartment had a nine times (95% CI: 2 -44) higher chance of showing pruritic behaviour than pigs in the control compartment.
