This study was carried out using Ixodes ricinus ticks collected during 2005 and 2006 from the Friuli Venezia Giulia (FVG) region in the northeastern part of Italy and an area along the Slovenian side of the western border of Italy. The results indicate that Rickettsia spp. is widely distributed throughout these areas, with the greatest prevalence in the central part of the FVG region. The prevalence of Rickettsia spp. was 4.5% during 2005 and 6.1% during 2006. By sequencing the 16S rRNA gene, we show for the first time the presence of Rickettsia helvetica in I. ricinus ticks in the FVG region and the presence of R. monacensis in ticks in both areas. Furthermore, we detected a sequence with a high homology with that of R. limoniae in a tick obtained from the alpine zone.

Abstract Six batches of four commercial hybrids of heavy pigs, reared for the production of Italian dry-cured hams, were identified for having homogeneous feeding and farm conditions. For a total of 235 pigs, slaughtered in the same slaughterhouse, carcass traits and muscle composition were measured. The pigs were genotyped for single nucleotide polymorphisms (SNPs) of Na+, K+-ATPase subunit alpha 2 (ATPase, Na+/K+ transporting, alpha 2 (+) polypeptide; ATP1A2), cystatin B (CSTB), mitochondrial 2,4-dienoyl-CoA reductase 1 (DECR1), leptin (LEP; 3 SNPs), melanocortin receptor 4 (MC4R), melanocortin receptor 5 (MC5R), sarcolipin (SLN) and titin (TTN) genes. All genes showed biallelic polymorphisms and the alleles were differently distributed between the six batches. Pigs were subsequentely clustered in “lean” and “fat” using either carcass traits (lean percentage, backfat thickness, loin muscle thickness, ham weight and ham cover fat thickness: 100 lean and 135 fat) or meat composition data (dry matter, protein, fat and ash of Biceps femoris and Vastus lateralis and pH after 24 hours: 126 lean and 109 fat). The association of gene polymorphisms with leaness and fatness of pigs was thus investigated using a logistic regression. ATP1A2, LEP (HinfI polymorphism) and MC4R, together with sex and ham weight were, included in the model to screen lean and fat pigs classified according to carcass traits data, yielding a correct classification of 71%. For the lean and fat pigs classified according to muscle composition, sex, CSTB, DECR1, MC5R and LEP (AciI/TaqI polymorphisms) were included in the regression analysis, that yielded a 66% of pigs correctly classified. These preliminary results may indicate that some of the selected candidate genes could be associated to production traits and are worth of further investigations.

Anetoderma associated with lyme disease: a case report.

Anetoderma is a rare skin disease characterized by circum-scribed areas of wrinkled, atrophic or slack skin due to the loss of elastic tissue in the dermis (1). Histologically, it is characterized by a decreased amount of dermal elastic tissue and variable levels of inflammatory infiltrate. Currently, anetoderma is classified as either a pri-mary or secondary form. The aetiopathogenesis of anetoderma is unknown. The frequent association of anetoderma with immune-mediated diseases and finding immunoglobulin at the anetodermic lesions suggests a possible immunological mechanism in the fragmenta-tion and/or loss of elastic fibres (2).

MwoI and SmaI RFLPs polymorphisms of porcine obese gene and their association with carcass and meat characteristics of heavy pigs

Romina Floris; Bruno Stefanon; Alberto Pallavicini; Piero Susmel; Giorgio Graziosi

The obese gene encodes leptin, a 16-kDa protein involved in the regulation of fat deposition and energy consumption. Backfat is one of the peculiar characteristics of Italian ham, and represents a fundamental quality factor. Therefore, the obese gene can be considered as a candidate marker for determining economically important production traits such as backfat thickness, feed intake, and growth rate in swine. The aim was to investigate the relationship between obese gene polymorphisms and carcass and meat characteristics of pigs reared for ham production. In the present research, the analyses of three new RFLPs are reported. An MwoI polymorphism occurs at nucleotide 1792, within the intron. Pigs heterozygous at this position have heavier thighs with a thinner layer of fat. Two SmaI polymorphisms occur at nucleotides 5018 and 5410 within the 3́ UTR of the obese gene. Animals heterozygous at position 5410 have characteristics suitable for the production of San Daniele ham: lower backfat thickness and heavier thighs with a thinner fat layer, relative to other genotypes
