Probiotic, antibiotic and combinations in Nile tilapia juveniles culture.

This study aimed to evaluate the effect of the commercial probiotic (Saccharomyces cerevisiae), antibiotic (florfenicol), and its combination for Nile tilapia culture. The experiment was arranged in a completely randomized design with five replications, and five treatments diets: Control: water and diet without additives; YD: yeast in the diet (1 g Kg-1); AW: antibiotic in the water (0.002 g L-1); AWYD: antibiotic in the water, and yeast in the diet (0.002 g L-1 and 1 g Kg-1); and AD: antibiotic in the diet (0.01 g kg-1). The growth parameters as total and standard length, weight, weight gain, biomass, Fulton's condition factor, specific growth rate and plasma cortisol of tilapia did not show the difference between the treatments. The survival rates and food conversion rate of fish were greater in treatment with florfenicol included in the diet. The commercial probiotic did not improve growth or survival. The administration of the antibiotic florfenicol in the water needs more studies. The inclusion of the antibiotic in the diet promotes growth and survival in Nile tilapia juvenile.

Esse artigo se trata de uma pesquisa que teve por objetivo compreender os modos de narrar o viver com HIV/aids de jovens soropositivos. Partese da ideia de performatividades do self, contribuição teórica do estudo de narrativas. A estratégia metodológica consiste de observação de participantes e entrevistas narrativas com 12 jovens soropositivos com idades entre 22 e 29 anos. O material foi submetido à análise dialógica/performática de narrativas, e serviu como suporte para a construção de narrativas ficcionais. Essa estratégia visa "embaralhar" os fragmentos das narrativas e criar "colagens", que são baseadas em fatos reais; porém devem ser lidas como ficção. Conclui-se que é necessária a ampliação da circulação de informações sobre o HIV/aids entre os jovens. Além disso, observa-se que as narrativas ficcionais se apresentam como uma alternativa para a exploração de novas formas de comunicação, possibilitando a inclusão das singularidades da vida após o diagnóstico.

This paper presents a study that aimed to understand the ways of narrating living with HIV/aidsinvolving young people. The idea of performativity of the self was a departing point, as a theoretical contribution from the narrative inquiry. The methodological strategy was composed of participant observation and narrative interviews with 12 seropositive youngsters between the ages of 22 and 29 years. The material was submitted to dialogic/ performance narrative analysis and was the basis for the construction of fictional narratives. This strategy consists of "shuffling" the fragments of the narratives and creating "collages", which are based on real facts, but are supposed to be read as fiction. We conclude that it is necessary to expand the circulation of information about HIV/aids among young people and that fictional narratives are presented as an alternative for the exploration of new forms of communication that include the singularities of life after diagnosis.
