Nutrient content in the muscle and skin of fillets from farmed rainbow trout (Oncorhynchus mykiss).

The nutrient content in the muscle and edible skin parts of rainbow trout (Oncorhynchus mykiss) fillets, sampled at two growth stages, was evaluated. The average concentrations of protein and essential amino acids were higher in the muscle than in the skin. The chemical scores reached a value of 1.0 for the amino acids in the muscle and ranged from 0.40 (tryptophan) to 0.94 (threonine) in the skin. The average lipid content and the saturated fatty acids/polyunsaturated fatty acids and n-6/n-3 ratios were higher in the skin than in the muscle, whereas the proportion of docosahexaenoic acid (C22:6 n-3) was higher in the muscle. Significant differences were found for the essential minerals analysed, except for Cu. The concentrations of Na, K and Mg were higher and those of Ca, P, Fe, Mn and Zn were lower in the muscle than in the skin. Significant effects of the fish growth on the composition were detected.

A genetic comparison of pig, cow and trout isolates of Lactococcus garvieae by PFGE analysis.

AIMS: Genetic comparison of Lactococcus garvieae isolated from mammals and fish. METHODS AND RESULTS: One hundred and ninety-seven L. garvieae isolates obtained from trout (n = 153), cow (n = 7) and pigs (n = 37) were genetically characterized by determining their pulsed-field gel electrophoresis (PFGE) profiles after macrorestriction with Bsp120I. Overall, L. garvieae isolates from pigs, cow and trout exhibited distinct PFGE patterns, with a low genetic relationship between them. Isolates from trout generated two pulsotypes [Genetic diversity (GD) 0.01] showing that the fish isolates were more genetically homogenous than the others. The L. garvieae isolates from cows displayed five (GD 0.71) different pulsotypes, while the swine isolates displayed 13 different pulsotypes (GD 0.35). Twenty-one of the 37 swine strains (56.8%) were grouped in a single cluster that included two closely related (93% similarity) pulsotypes. These pulsotypes exhibited a high frequency of isolation from different organs of the animals, and they were also broadly distributed among herds, suggesting a wide distribution across the swine population. This suggests that L. garvieae might be able to colonize different organs of the swine cardio-respiratory system. CONCLUSIONS: Results indicate that most L. garvieae isolates from pigs and trout exhibited a distinct genetic background. SIGNIFICANCE AND IMPACT OF THE STUDY: The present study describes the isolation of L. garvieae from both diseased and healthy pigs for the first time, and the findings suggest that pigs could be a previously unknown reservoir of this pathogen.

[Tracheobronchial wall thickening secondary to herpesvirus infection in a patient with Goods syndrome]. / Engrosamiento traqueobronquial producido por herpesvirus en un paciente con síndrome de Good.

We describe an oligosymptomatic patient with Good syndrome (thymoma and hypogammaglobulinemia) in who a follow-up chest computed tomography showed circumferential tracheobronchial wall thickening. Bronchoscopy demonstrated tracheobronchitis with necrotic, vesicular and blister areas. The histopathological and immunohistochemical findings were compatible with herpes simplex virus infection. The therapeutical response to oral acyclovir was satisfactory.

Engrosamiento traqueobronquial producido por herpesvirus en un paciente con síndrome de Good / Tracheobronchial wall tickening secondary to herpesvirus infection in a patient with good syndrome

Se decribe el caso de un paciente con síndrome de Good (timoma e hipogammaglobulinemia), que estando oligosintomático, se le realizó una tomografía computerizada de tórax de control en la que se evidenció un engrosamiento circunferencial de la pared traqueobronquial. Una broncoscopia demostró datos de una traqueobronquitis con áreas necróticas y vesículo-ampollosas, siendo los hallazgos histopatológicos y de inmunohistoquímica compatibles con una infección por el virus del herpes simple. La respuesta terapéutica al aciclovir oral fue satisfactoria
