Varias species residentes en la familia Botryosphaeriaceae son importantes patógenos causantes de cancros y «dieback» en numerosas plantas leñosas. En Uruguay, cancros del fuste observados en plantaciones de Eucalyptus globulus han estado asociados a Neofusicoccum eucalyptorum (=Botryosphaeria eucalyptorum), N. ribis (=B. ribis) y B. dothidea. Estos hongos también habitan como endófitos en hojas, ramas y fustes asintomáticos de Eucalyptus volviéndose patógenos luego de la ocurrencia de algún estrés. Existen evidencias que sugieren que otras especies de Botryosphaeriaceae, además de las antes mencionadas podrían causar cancros en Eucalyptus spp. y mirtáceas nativas en Uruguay. En este estudio, identificamos las especies Botryosphaeriaceae presentes en Eucalyptus spp. y en mirtáceas nativas, y analizamos la diversidad genética entre los aislamientos aislados de ambos grupos de hospederos. Muestras de material vegetal de Eucalyptus spp. y mirtáceas nativas con y sin síntomas fueron colectadas desde diversos puntos del país. Los cultivos fúngicos monospóricos obtenidos de dichas muestras, fueron identificados en
base a la morfología de conídios y a técnicas moleculares mediante comparación de secuencias de ADN correspondientes a la región ITS del ADN ribosomal. Los resultados muestran que aislamientos identificados dentro del complejo N. parvum-N. ribis, y otros identificados como B. dothidea fueron aislados de ambos hospederos, Eucalyptus spp. y mirtáceas nativas. Por el contrario, N. eucalyptorum fue aislado únicamente de Eucalyptus spp., mientras que aislamientos de una especie relacionada a Diplodia seriata (=B. obtusa) fueron obtenidos únicamente de árboles nativos. Este estudio permite expandir los conocimientos acerca de las especies Botryosphaeriaceae presentes en mirtáceas nativas e introducidas en Uruguay. //Species of the Botryosphaeriaceae are important pathogens causing cankers and die-back on many woody plants. In Uruguay, Neofusicoccum eucalyptorum (=Botryosphaeria eucalyptorum), N. ribis (=B. ribis) and B. dothidea have previously been associated with stem cankers on plantation grown Eucalyptus globulus. These fungi also exist as endophytes in healthy Eucalyptus leaves, twigs and stems, typically causing disease after the onset of stress. There is good evidence to suggest that species of the Botryosphaeriaceae, other than those previously reported, could cause cankers on Eucalyptus spp. and native Myrtaceae trees in Uruguay. In this study, we identified the Botryosphaeriaceae present on Eucalyptus spp. and on native Myrtaceae trees, and considered the genetic diversity between isolates found on both groups of hosts. Symptomatic and asymptomatic material was collected countrywide from Eucalyptus spp. and native Myrtaceae. Monosporic cultures were identified based on conidial morphology and comparisons of DNA sequences for the ITS region of the rDNA operon. Results revealed that isolates of the N. parvum-N. ribis complex, and B. dothidea were present on both Eucalyptus spp. and native Myrtaceae. In contrast, N. eucalyptorum was found only on Eucalyptus spp. and Diplodia seriata-related (=B. obtusa) isolates were obtained only from native trees. This study expands the knowledge of the occurrence of Botryosphaeriaceae on native and introduced Myrtaceae in Uruguay.

ABSTRACT.
The aim of this study was to evaluate production performance, carcass characteristics and nutritive value of meat of rabbits reared under the 2 prevailing feeding strategies iiji Uruguay. One week after weaning, 96 purebred V line rabbits were randomly distributed between 2 treatments: (T1) commercial pelleted food ad libitum and (T2) commercial pelleted food ad libitum plus fresh alfalfa ad libitum. Each treatment included 12 cages containing 4 individuals each (2 males and 2 females). Growth performance characteristics (live weight evolution, commercial food consumption and food/gain ratio) were evaluated. The consumption of alfalfa was not measured. Rabbits were slaughtered at a live weight of 2500 g and carcass characteristics were evaluated. Samples of meat and dissectible fat were analysed to determine intramuscular fat content at muscle L. dorsi, dissectible fat and intramuscular fat composition, minerals (Zn, Fe, Mg and Na), vitamin E and purines. Sensory evaluations were conducted to assess the effect of treatments on the consumer's perception of differences and the existence of attributes determining preferences. Differences between treatments were significant for total commercial food intake (23356 vs: 20930 g/cage; P<0.001) and feed conversion ratio (3.82 vs. 3.41; P<0.01) for T1 and T2 respectively. No significant differences were found in average daily gain, age at slaughter and carcass characteristics. There were no significant differences in the intramuscular fat content. The fatty acid composition of dissectible and intramuscular fat was affected by the inclusion of alfalfa in the diet increasing the linolenic acid content (1.82 vs. 3.28% and 2.29 vs. 5.15% for T1 and T2 at intramuscular and dissectible fat, respectively; P<0.001), and improving the n-6/n-3 relationship (8.60 vs. 5.82 and 11.58 vs. 5.64 for T1 and T2 at intramuscular and dissectible fat, respectively; P<0.001). There were no significant differences in vitamin E, Fe or Zn content between treatments, but differences were significant in Mg (22.5 vs. 24.4 mg/100 g for T1 and T2; P<0.05) and Na (44.1 vs. 48.2 mg/100 g; P<0.05). In the sensory evaluation, panellists significantly perceived differences between treatments with 95% confidence.
