1. Pure neural leprosy or amyloid neuropathy? Systematic review and clinical case report
SUMMARY OBJECTIVE: To review the literature and to report a clinical case with initial suspicion of pure neural leprosy and final diagnosis of amyloid neuropathy. METHODS: The study was conducted in two stages. In stage one, a systematic literature review was carried out, with searches performed in the PubMed, Medline, and Lilacs databases, as well as in t

2. [Detecção dos genes icaA, icaD e bap e produção de biofilme por Staphylococcus aureus e estafilococos não-aureus isolados de mastite clínica e subclínica bovina]
RESUMO Algumas espécies de Staphylococcus causam infecções crônicas intramamárias e podem levar à formação de biofilme. No presente estudo, levantou-se a hipótese de que as espécies de Staphylococcus isolados da mastite bovina são capazes de formar biofilme in vitro associado à presença dos genes icaA, icaD ou bap. Um total de 200 isolados de St

4. In vivo phagocytosis and hematology in Astyanax altiparanae, a potential model for surrogate technology
Resumo Apesar do potencial apresentado pela tecnologia de propagação mediada para a aquicultura e conservação de peixes Neotropicais, o pobre entendimento do sistema imune do hospedeiro pode resultar na rejeição e destruição do material do doador. Com isso, se fazem necessários o estudo e o desenvolvimento de métodos para análise tanto dos efeitos

5. MINIMUM BACTERICIDAL CONCENTRATION OF COMMERCIAL DISINFECTANTS ON STAPHYLOCOCCUS SPP. ISOLATED FROM MASTITIS IN GOATS AND DETECTION OF THE icaD GENE
Resumo O presente trabalho objetivou avaliar a eficácia in vitro de desinfetantes comerciais frente à Staphylococcus spp. isolados de casos de mastite em cabras e, relacionar a resistência observada com a presença do gene icaD. A microdiluição em caldo foi utilizada para avaliar a atividade antimicrobiana in vitro dos desinfetantes, enquanto a técnica

6. Henoch-Schönlein purpura nephritis associated with monoclonal gammopathy of renal significance: a case report
Monoclonal gammopathy of renal significance (MGRS) can present with different morphologic features and lead to kidney failure. The Henoch-Schönlein purpura nephritis (HSPN) that cannot be relieved by treatment with glucocorticoid and immunosuppressive agents suggests the presence of monoclonal gammopathy in adult patients. The present study reports on a sin

7. Staphylococcal slime layers and biofilm from different origins
RESUMO: O gênero Staphylococcus abrange algumas das bactérias patogênicas mais importantes tanto para humanos como para animais. Ele é responsável pela mastite bovina e otite canina, além de estar presente na microbiota de animais e como contaminante em alimentos. Sua patogênese está relacionada à formação de cápsula e biofilme, que contribuem p

8. Azo Dye Mineralization by Phanerochaete Chysosporium in a Sequencing Bath Reactor
ABSTRACT The mineralization of the azo dye congo red by the fungi Phanerochaete chrysosporium was studied in two sequential batch bioreactors (R1 and R2), operated in cycles of 48 h (step I) and 24 h (step II). In step I, glucose concentration was 1 g.L-1 in both reactors and in step II, 1 g.L-1 of glucose was maintained in R1, but R2 received no addition of

9. Characterisation of the vascular pathology in Sigmodon hispidus (Rodentia: Cricetidae) following experimental infection with Angiostrongylus costaricensis (Nematoda: Metastrongylidae)
BACKGROUND Angiostrongylus costaricensis is a nematode that causes human abdominal angiostrongyliasis, a disease found mainly in Latin American countries and particularly in Brazil and Costa Rica. Its life cycle involves exploitation of both invertebrate and vertebrate hosts. Its natural reservoir is a vertebrate host, the cotton rat Sigmodon hispidus. The

10. INVESTIGATION OF BIOFILM FORMATION IN COAGULASE-NEGATIVE STAPHYLOCOCCI ISOLATED FROM PLATELET CONCENTRATE BAGS
Platelet Concentrates (PCs) are the blood components with the highest rate of bacterial contamination, and coagulase-negative staphylococci (CoNS) are the most frequently isolated contaminants. This study investigated the biofilm formation of 16 contaminated units out of 691 PCs tested by phenotypic and genotypic methods. Adhesion in Borosilicate Tube (ABT)

11. Syndrome in Question
Immunoglobulin light chain amyloidosis is the most common acquired systemic amyloidosis. Its presentation is often insidious and progressive, which may delay diagnosis. The authors describe a rare case of immunoglobulin light chain amyloidosis in a 34-year-old man with scleroderma-like manifestation substantiated by multifarious laboratory investigations and

12. Detection of exopolysaccharide production and biofilm-related genes in Staphylococcus spp. isolated from a poultry processing plant
Staphylococcus spp. can survive in biofilms for long periods of time, and they can be transferred from one point to another and cause environmental contamination in food processing. The aim of this study was to detect Staphylococcus strains isolated from a poultry processing plant by the presence of adhesion genes and the phenotypic production of exopolysacc
