Abomasums from 641 alpine wild ruminants representing five different species (Cervus elaphus, Capreolus capreolus, Rupicapra rupicapra, Capra ibex, Ovis musimon) and from 19 domestic sheep (Ovis aries) from alpine areas were examined in order to investigate the host-specificity of abomasal helminths. Nine out of 20 helminth species were found in at least(More)
The present study describes the comparison between a modified agglutination test (MAT) and the indirect fluorescent antibody test (IFAT) for the detection of Toxoplasma specific IgG antibodies in dog and cat sera. MAT showed an “almost perfect” agreement with IFAT in detecting positive and negative results in cat sera, where as only a “substantial”(More)
A serological survey of respiratory virus infections was carried out from 1998 to 2001 in Lecco province, Italy, as part of a health monitoring programme in a population of alpine chamois, many of which died of pneumonia in autumn and winter 2000 to 2001; 194 carcases of all age classes were found over a short period and in a small area. Eighteen of them,(More)
The three-dimensional histology technique is used in human medicine for the evaluation of complete lateral and deep surgical margins. In this study, the technique was applied to 48 excised feline injection-site sarcoma specimens. The predictive value of the histological margin status and tumour grading on local recurrence was investigated. In 32/48 cases,(More)
OBJECTIVE in March 2005, the Italian National Monitoring System on Chemical Residuals in Food of Animal Origin detected levels of the pesticide beta-hexachlorocyclohexane (ß-HCH) that were 20 times higher than the legal limit of 0.003 mg/kg in bulk milk from a dairy farm in the Sacco River valley. ß-HCH, a lindane isomer and possible human carcinogen, was(More)
In May 2005, beta-hexachlorocyclohexane (β-HCH) was found in a sample of bovine bulk milk from a farm in the Sacco River valley (Latium region, central Italy). The primary source of contamination was suspected to be industrial discharge into the environment with the Sacco River as the main mean of dispersion. Since then, a surveillance programme on bulk(More)
The susceptibility of sheep to scrapie is under the control of the host’s prion protein (PrP) gene and is also influenced by the strain of the agent. PrP polymorphisms at codons 136 (A/V), 154 (R/H) and 171 (Q/R/H) are the main determinants of susceptibility/resistance of sheep to classical scrapie. They are combined in four main variants of the wild-type(More)
The eradication of tuberculosis, brucellosis and leucosis in cattle has not yet been achieved in the entire Italian territory. The region of Lazio, Central Italy, represents an interesting case study to evaluate the evolution of costs for these eradication programmes, as in some provinces the eradication has been officially achieved, in some others the(More)
BACKGROUND Epidemiological investigations were carried out in the Lazio Region to assess the status of canine filariosis and to evaluate the actual risk for veterinary and medical public health. METHODS Since August 2001 to June 2003, a total of 972 canine blood samples, collected in public kennels and from private owners animals of the 5 Provinces of the(More)
