[more ▼] During the 1992-1993 133 seabirds found on Belgian beaches were necropsied. Most frequent species were the guillemot (Uria aalge), the oystercatcher (Haematopus ostralegus), the kittiwake (Rissa tridactyla), the razorbill (Alca torda) and the herring gull (Larus argentatus). The three main observations were, in decreasing order, cachexia, acute and hemorrhagic gastroenteritis, and oil contamination of plumage and intestinal tract. The pelagic origin of seabirds was associated with all 3 observations; oil contamination was associated with acute gastro-enteritis and cachexia and, finally, the immature character was associated with cachexia. A hypothetical mechanism of death would be oiled pelagic seabirds that become cachectic and die of acute gastroenteritis. It is unlikely that seabirds act as a reservoir for bacteria, that were only occasionally identified in our material. Therefore, it appears that infectious agents play a minor role in seabirds stranding.

[more ▼] While the hereditary nature of the double-muscling phenotype (a generalized muscular hypertrophy documented in several cattle breeds) is well established, its precise segregation mode has remained controversial. Both monogenic models (autosomal dominant or recessive) and oligogenic models have been proposed. Using a panel of 213 bovine microsatellite markers, and an experimental pedigree obtained by backcrossing double-muscled (Belgian Blue)xconventional (Friesian) F1 dams to double-muscled sire, we have mapped a locus on bovine Chromosome (Chr) 2 that accounts for all the phenotypic variance in the backcross generation. This locus, referred to as mh (muscular hypertrophy), has been positioned with respect to a map composed of seven Chr 2-specific microsatellites, at 2 cM from the closest marker. This result confirms the validity in the Belgian Blue population of the monogenic model involving an autosomal mh locus, characterized by a wild-type + and a recessive mh allele, causing the double-muscling phenotype in the homozygous condition. The linkage relationship between the mh locus and the Chr 2 markers was confirmed in three informative pedigrees collected from the general Belgian Blue Cattle population, reinforcing the notion of genetic homogeneity of the double-muscling trait in this breed. This work paves the way towards marker-assisted selection for or against the double-muscling trait, and towards positional cloning of the corresponding gene.
