  1. Potential cross-contamination of similar Giardia duodenalis assemblage in children and pet dogs in southern Brazil, as determined by PCR-RFLP

    Quadros, Rosiléia Marinho de; Weiss, Paulo Henrique Exterckotter; Marques, Sandra Marcia Tietz; Miletti, Luiz Claudio
    Giardia duodenalis is an enteric parasite that has distinct genetic groups. Human infections are mainly caused by assemblages A and B, although sporadic infections by assemblages C and D have also been reported. Animals can be infected by a wide range of assemblages (A to H). The aim of this study is to identify the assemblages and sub-assemblages of G. duodenalis with zoonotic features in fecal samples of school-aged children, and in dogs that coexist in the same households in Lages, Santa Catarina, Brazil. Fecal samples of 91 children and 108 dogs were obtained and G. duodenalis cysts were detected...

  2. Effect of incorporation of nutraceutical capsule waste of safflower oil in the mechanical characteristics of corn starch films.

    Campo, Camila de; Costa, Tania Maria Haas; Rios, Alessandro de Oliveira; Flôres, Simone Hickmann
    Biodegradable films blends made of safflower oil nutraceutical capsules waste: corn starch (20:4, 30:4, 40:4 and 50:4) were prepared. The objective of this study was to evaluate the influence of addition of different concentrations of safflower oil nutraceutical capsule waste in the mechanical properties (tensile strength, elongation at break, Young’s modulus) and thickness of corn starch films. A decrease in tensile strength and Young’s modulus and an increase in elongation at break were observed with the increase in the content of the nutraceutical capsule waste. The results showed that the blends of safflower oil capsules waste-corn starch films demonstrated promising...

    Little information about Shigella responsible for foodborne shigellosis is available in Brazil. The present study aimed to investigate the antimicrobial resistance and PCR-ribotyping patterns of Shigella isolates responsible for foodborne outbreaks occurred in Rio Grande do Sul State (RS), Southern Brazil in the period between 2003 and 2007. Shigella strains (n=152) were isolated from foods and fecal samples of victims of shigellosis outbreaks investigated by the Surveillance Service. Identification of the strains at specie level indicated that 71.1% of them were S. flexneri, 21.5% S. sonnei, and 0.7% S. dysenteriae. Ten strains (6.7%) were identified only as Shigella spp. An...
