巴西某地区的第一部综合性的海藻植物志于1957年由Joly出版,该植物志描述并解释了105个分类单位。20年后,oliveira和Berchez重新调查了该地区,只发现了69个分类单位,褐藻数量显著减少。1991年在三个物种丰度最大的研究站进行的另一次调查中,发现有同样的减少趋势,而且没有发现褐藻的存在。生物多样性的这种减少归因于污染的增加。这里我们列举了1998～1999年进行的一次新的调查结果。这次调查显示20世纪50年代记录的某些物种得到了恢复,其中包括7种褐藻。物种数的这一增长被认为是当地政府作出的减少污染的努力以及一个海底污水终端建成的结果。

Objective: To determine the main microbial genotypes and their antimicrobial resistance and susceptibility profile commonly used in the treatment of oncologic patients with febrile neutropenia, carried out through the review of the clinical histories of the patients’ medical records at the Hospital do Cancer de Muriaé-Fundacao Cristiano Varella. Methods: Quantitative research, determined the susceptibility profile of microorganisms in patients with febrile neutropenia from April 2007 to April 2008 by reviewing clinical histories of patients’ medical records at the referred hospital. Results: Of the total of 8 patients evaluated with Gram-negative microorganisms, 50% of the patients were female and 50% were male. Of the 18 patients evaluated with Gram-positive microorganisms 66% were female and 34% male. Gram-positive bacteria are prevalent and cause around 60% of documented bacteremias, although Gram-negative bacteria are more common in febrile neutropenic patientes. Conclusion: Exaggerated use of antimicrobials in hospitalized patients leads to the suppression of drug-sensitive microorganisms from the intestinal flora and promotes the persistence and growth of resistant bacteria. The antibiotic should be used in a curative manner with other therapeutic measures with the determined bacterial infection.

Bacteroides species are nearly half of the fecal flora community and some are host symbionts crucial to host nutrition and systemic immunity. Among Bacteroides species B. fragilis strains are considered to be the opportunistic ones, being the most isolated anaerobic bacteria in clinical samples. Cell-free supernatants of 65 B. fragilis strains were assayed and they were capable of inducing vacuolating phenotype on Vero cells lineage. The supernatant of the Bacteroides fragilis ATCC 23745 strain was elicited to have the strongest vacuolating effect on Vero cells monolayers and peritoneal macrophages. Some drastic cell alterations were observed, such as a general disorganization of cytoplasm and chromatin condensation, evidencing cell death. By transmission electron microscopy it was confirmed that the vacuoles observed were, in fact, swollen mitochondria. An immunocytochemical assay, TUNEL, was used to confirm this hypothesis and showed that Vero cells and peritoneal macrophages were dying by apoptotic process after exposition of B. fragilis cell-free supernatant. Physical analysis of the apoptotic factor has revealed properties similar to short-chain fatty acids. After gas chromatography and mass spectrometry analysis, phenylacetic acid (PA) was characterized as the major compound present in the most purified active fraction. We believe that the PA is responsible for the pro-apoptotic effect elicited by the supernatant of B. fragilis cultures.
