ABSTRACT
Quarenta e três ovelhas foram distribuídas em quatro tratamentos em um delineamento de blocos casualizados. Os tratamentos consistiram no fornecimento de dietas de flushing, formuladas com farelo de soja (FFS) ou com glúten de milho e farelo de algodão (FGM+FA) por 28 dias antes da ovulação, seguido pelo fornecimento de dietas de flushing ou de uma dieta de mantença (DM) durante 28 dias após a ovulação: T1 - FFS antes e após a ovulação (n=12); T2 - FFS antes da ovulação e DM após (n=11); T3 - FGM+FA antes e após a ovulação (n=10); T4 - FGM+FA antes da ovulação e DM após (n=10). O ganho de peso e o peso final não diferiram (P>0,05) entre os animais dos tratamentos. O ECC final foi maior (P<0,05) nas ovelhas do tratamento T3 do que nas do tratamento T2. A concentração de N-ureico foi maior (P<0,05) nas ovelhas dos tratamentos T1 e T3 do que naquelas dos tratamentos T2 e T4. A taxa de gestação e a prolificidade não diferiram (P>0,05) entre os animais. As dietas de flushing antes da ovulação, seguidas pelo fornecimento destas mesmas dietas ou de uma dieta de mantença após a ovulação, não alteraram a taxa de gestação e a prolificidade.
Forty-tree ewes were assigned to four treatments in a randomized block design. The treatments consisted of two flushing diets, composed of soybean meal (SMF) or corn gluten and cottonseed meal (CG+CMF) furnished for 28 days before ovulation, and feeding with flushing diets or a maintenance diet (MD) for 28 days after ovulation: T1 - (SMF) before and after ovulation (n=12); T2 - SMF before ovulation and a MD after (n=11); T3 - CG+CMF before and after ovulation (n=10); T4 - CG+CMF before ovulation and MD after (n=10). The gain in BW and the final BW did not differ (P>0,05) between treatments. The final BC was higher (P>0,05) in ewes in T3 treatment than in those in treatment T2. The urea N concentration was higher (P<0,05) in ewes in treatments T1 and T3 than those in treatments T2 and T4. The pregnancy rate and prolificacy did not differ (P>0,05) between treatments. The flushing diets before ovulation and feeding with this same diet or a maintenance diet after ovulation did not alter the pregnancy rate and prolificacy.

Enterococcus faecalis isolates were examined by an automated identification and susceptibility system. Almost all of the 97 isolates were ampicillin susceptible (n = 86) and tetracycline resistant (n = 89). All were nitrofurantoin susceptible. About a third of isolates showed high level resistance to the aminoglycosides streptomicin and gentamicin and this was usually associated with ciprofloxacin resistance (n = 34). Seven isolates were vancomycin resistant, including one that was ampicillin resistant. Most forms of resistance described elsewhere were found.
Aislados de enterococcus faecalis fueron examinados mediante un sistema automatizado de identificación y susceptibilidad. Casi todos los 97 aislados examinados fueron susceptibles a la ampi-cilina (n = 86) y resistentes a la tetraciclina (n = 89). Todos fueron susceptibles a la nitrofurantoína. Alrededor de una tercera parte de los aislados mostró un alto nivel de resistencia a los aminoglicósidos, por regla general asociada con la resistencia a la ciprofloxacina (n=34). Siete aislados resultaron resistentes a la vancomicina, incluyendo uno que fue resistente a la ampicilina. Se encontraron la mayoría de las formas de resistencia descritas en otras partes.

This paper describes the devastating outcome of a neonate who presented with severe late onset group B beta-haemolytic streptococcal (GBS) disease. There were extensive infarcts of the brain and gangrene of the toes. The purpose of this report is to alert healthcare workers of the unusual presentation and that fatal late onset group B beta-haemolytic streptococcal disease may occur despite early and effective management
