RESUMO
Dissotichus eleginoides has a discontinuous circumpolar geographic distribution restricted to mountains and platforms, mainly in Subantarctic and Antarctic waters of the southern hemisphere, including the Southeast Pacific, Atlantic and Indian oceans and in areas surrounding the peninsular platforms of subantarctic islands. The aim of this work was to determine and characterize the gastrointestinal parasitic and microbial fauna of specimens of D. eleginoides captured in waters of the south-central zone of Chile. The magnitude of parasitism in D. eleginoides captured in waters of the south-central zone of Chile is variable, and the parasite richness is different from that reported in specimens from subantarctic environments. Next-generation sequencing (NGS) of the microbial community associated to intestine showed a high diversity, where Proteobacteria, Firmicutes, and Bacteriodetes were the dominant phyla. However, both parasitic and microbial structures can vary between fish from different geographic regions.
RESUMO
Fundamentos: Varios estudios evalúan si el consumo de probióticos puede modificar el peso corporal. La cepa Lactobacillus fermentum UCO-979C es una cepa de origen gástrico y éste constituye el primer estudio en humanos. El objetivo fue evaluar el efecto del consumo de la cepa L. fermentum UCO979C en el peso, el porcentaje de masa grasa, masa magra, circunferencia de la cintura y hábitos alimenticios de un grupo de adultos jóvenes de la Universidad de Concepción, Chile.Métodos: Ciento cuatro estudiantes universitarios se dividieron en dos grupos. El grupo intervenido (n = 56) consumió una gelatina que contenía la cepa probiótica, mientras que elgrupo control (n = 46) consumió una gelatina placebo. Los hábitos alimenticios, la composición corporal se evaluaron al comienzo y al final de la intervención. Resultados: No se observaron diferencias significativas después de 12 semanas entre el grupo control y el grupo intervenido en peso, porcentaje de masa grasa, masa magra y circunferencia de la cintura, pero se observaron diferencias significativas en los hábitos alimenticios. A la semana 12 el grupo intervenido mostró un aumento muy significativo de la masa magra y un mayor consumo de productos lácteos y frutas respecto al inicio del estudio.Conclusiones: El consumo del probiótico no modificó ni el peso ni la composición corporal, pero sí modificó los hábitosalimenticios, aumentando el consumo del desayuno, frutas y productos lácteos.

Background: Several studies evaluate whether the consumption of probiotics can modify body weight. The Lactobacillus fermentum UCO-979C strain is a strain of gastric origin and this constitutes the first study in humans. Theobjective was to evaluate the effect of the consumption of the L. fermentum UCO-979C strain on weight, percentage of fat mass, lean mass, waist circumference and eatinghabits of a group of young adults from the University of Concepción, Chile.Methods: One hundred and four university students were divided into two groups. The intervened group (n = 56) consumed a gelatin containing the probiotic strain, while thecontrol group (n = 46) consumed a placebo gelatin. Eating habits and body composition were evaluated at the beginning and at the end of the intervention. Results: No significant differences were observed after 12weeks of intervention in weight, percentage of fat mass, lean mass, and waist circumference, but significant differences were observed in eating habits. The intra-group analysis showed a very significant increase in lean mass anda higher consumption of dairy products and fruits in the group that received the probiotic.Conclusions: The consumption of the probiotic did not modify neither the weight nor the body composition, but it did modify the eating habits, increasing the consumption of breakfast, fruits and dairy products.
