The genetic variation of bovine viral diarrhoea virus (BVDV) was studied by comparative nucleotide sequence analysis of 26 Italian field strains collected during the period 1995-2000 in 18 cattle herds. A fragment within the 5'-untranslated region (UTR) was sequenced directly from gel-purified products obtained by reverse transcription polymerase chain(More)
The objectives of this study were to evaluate the presence of intramammary infections (IMI) in dairy buffaloes and to examine the relationships among IMI, somatic cell counts (SCC), and milk production traits. Two farms in northern Italy were visited monthly for a complete milking season. Quarter-based milk samples were collected at each visit from 46(More)
The prevalence of intra-mammary infections in dairy herds was studied in Hamdallaye, Niger. A total of 956 milk samples were collected in 2007 from 239 lactating cows of four local breeds in eight traditional herds; the first sampling was undertaken in the dry season at morning milking, and the second in the rainy season at evening milking. Staphylococcus(More)
Composite milk samples from 548 cows, and samples from feces, feed, bedding, water, liners (before and after milking), and the postdipping product were aseptically collected from 2 Italian dairy herds from February to November of 2006. Prototheca zopfii was isolated from 11.9% of milk samples, 15% of feces, and 33.3% of bedding samples. No viable cells of(More)
alpha(1)-Acid glycoprotein (AGP, orosomucoid) is a normal constituent of bovine blood. AGP is an immunocalin, a binding protein that can also exert several immunomodulatory functions. In this paper we investigated the effect of bovine alpha(1)-acid glycoprotein (boAGP) on spontaneous and staurosporine-induced apoptosis of blood derived monocytes purified(More)
MicroRNAs (miRNAs) are a family of regulatory molecules involved in many physiological processes, including activation of cells of the immune system. This study investigated the effect of Escherichia coli lipopolysaccharide (LPS) and Staphylococcus aureus enterotoxin B (SEB) on the expression of five miRNAs involved in the inflammatory response, including(More)
A large scale screening of the in vitro susceptibility of 105 strains of Prototheca zopfii to a panel of polyene antibiotics (amphotericin B, nystatin, primaricin and filipin) was conducted. Strains studied were isolated from dairy-associated environments in five different localities. Groups 1-4 included strains recovered from four separate regions of(More)
The goal of this study was to evaluate the effects of dietary protected fish oil (FO) on phenotypic variation in blood, milk leukocytes, and some productive and metabolic parameters in periparturient dairy goats. About 12 Alpine goats, selected from a larger group of second-parity animals, were fed from 15 days before kidding until the 15th day of lactation(More)
The present study was undertaken during an outbreak of clinical and subclinical mastitis in 14 dairy cows caused by Candida rugosa, in which high somatic cell counts were seen and cases did not respond to antibiotic treatment. Intramammary infection cured spontaneously in 10 cows, whereas 4 cows were culled as a result of persistent infections. Repeated(More)
