both) to reduce the colonization of Salmonella enterica in vitro was determined. A DCA with factorial arrangement (3x3) was used, being the factors the microorganisms and diffusion methods (direct, filtered and diluted) in the inhibition of the confrontation of microorganisms, with the use of the Kirby-Bauer technique. Survival in bile salts performed by the CFU count, under a design that had four treatments. The microorganisms with the application of three methods against Salmonella enterica had a favorable growth at 24 hours, obtaining a greater development with Lactobacillus brevis + Bacillus subtilis by filtration method. Survival to bile salts, no variability of results was found. However, L. brevis without bile salts stood out from minute 30 to minute 120. It is concluded that both microorganisms meet physical and biological characteristics, being suitable alternatives to be used as probiotics in animal feed for animal production purposes.
Con el fin de evaluar la influencia de la musicoterapia como tratamiento coadyuvante en la recuperación de pacientes posquirúrgico, se seleccionaron 20 perras mestizas entre 3 años y 6 meses, con un peso promedio de 10,90 ± 0,58 kg, sin enfermedades preexistentes, las cuales se sometieron a ovariosalpingohisterectomía (OSH) realizada por línea media. Fueron elegidos al azar 10 animales que se sometieron a musicoterapia (T1), mientras que el resto permanecieron como grupo control (T2), con igual alimentación. Se estudiaron las variables dolor (DL) (a través de la escala modificada de Melbourne y Glasgow), frecuencia cardiaca (FC), frecuencia respiratoria (FR), consumo de alimento (CA) y peso final (PF), durante siete días. Las observaciones se analizaron a través de una prueba de T-Student. Los resultados fueron promedios, con efectos estadísticos (p 0,05), para T1 de 1,49 (DL); 20,85 r. p. m. (FR); 402,66 g (CA) y 12,65 kg (PF). Mientras que para el control (T2) fueron de 6,82 (DL); 28,28 r. p. m. (FR); 357,69 g (CA) y 11,92 kg (PF). Se concluye que la musicoterapia (T1) posquirúrgica en estas condiciones es una alternativa viable en la recuperación del paciente.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
