ABSTRACT
ABSTRACT Although sporotrichosis requires a broad approach for control, few reports have described the relationship between the index case and secondary contacts. In the present work, we report an outbreak involving a woman, a dog, and two cats from the same household environment, including the clinical and epidemiological aspects and outcomes, and discuss the importance of a One Health approach to face this neglected disease. The joint efforts of professionals such as veterinarians and physicians are essential for early diagnosis and surveillance, which contributes to the rapid identification and control of zoonotic sporotrichosis outbreaks.
ABSTRACT
Abstract Pollen is used in the human diet as a food supplement because of its high nutritional value; however, this product is prone to fungal contamination that could potentially generate toxins that are harmful to human health. This study aimed to verify the floral diversity of commercial brands of bee pollen and their mycotoxicological safety for human consumption. A total of 27 bee pollen samples were analyzed; these samples represented commercial brands, either showing an inspection seal or not, marketed in the State of Rio de Janeiro. The analyzed parameters included floral diversity through palynological analysis, water activity, fungal counts, identification and toxigenic profiles. The palynological analysis identified nine plant families, of which the Asteraceae was predominant. Analysis of hygienic quality based on fungal load showed that 92% of samples were reproved according to the commercial, sanitary, and food safety quality indicators. Aspergillus, Cladosporium and Penicillium were the most common genera. Toxigenic evaluation showed that 25% of the A. flavus strains produced aflatoxins. The high rate of contamination of products bearing an inspection seal emphasizes the need to monitor the entire procedure of bee pollen production, as well as to revise the current legislation to ensure safe commercialization of this product.

Nerium oleander é uma planta ornamental responsável por intoxicações em animais e humanos. Todas as partes da planta contém glicosídeos cardiotóxicos, principalmente a oleandrina. Alguns autores apontam que a toxicidade da planta apresentaria variação em função da cor da flor. O objetivo deste trabalho foi determinar se existe variação na concentração de oleandrina nas folhas de N. oleander de exemplares da planta com diferentes cores de inflorescências. Foram coletadas 10 amostras de folhas para cada tipo de flor (branca, rosea e vermelha). Os níveis de oleandrina foram determinados por meio de HPLC-UV após extração com metanol, precipitação com acetato de chumbo e separação em cartucho de C18. A média da concentração obtida em todas as folhas analisadas foi de 4,89mg g-1, sendo 6,20±4,08mg g-1 na variedade de flores brancas, 4,16±3,44mg g-1 na de flores roseas e 4,31±1,99mg g-1 na de flores vermelhas. As concentrações de oleandrina não apresentaram diferença estatisticamente significante entre as variedades de flores.
Nerium oleander is an ornamental plant responsible for poisoning in animals and humans. All parts of the plant contain cardiotoxic glycosides, mainly oleandrin. Some authors suggest that the toxicity of the plant would present a dependence on flower color. The objective of this study was to determine whether there is variation in the concentration of oleandrin in the leaves of N. oleander specimens of different colors of flowers. Ten samples of leaves from each variety of flower (white, pink and red) were collected. Oleandrin levels were determined by HPLC-UV after extraction with methanol, precipitation with lead acetate and separation with C18 cartridge. The average concentration obtained in all analyzed leaves was 4.89mg g-1, being 6.20±4.08mg g-1 in variety of white flowers, 4.16±3.44mg g-1 in pink flowers, and 4.31±1.99mg g-1 in red flowers. The concentrations of oleandrin did not show statistically significant difference between the varieties of flowers.
ABSTRACT
A maioria das cozinhas de escolas públicas brasileiras não possui estrutura adequada para a manipulação higiênica dos alimentos, desde a recepção da matéria-prima, até a sua distribuição. Deste modo objetivou-se avalia as condições físicas e de funcionamento das cozinhas de 15 escolas estaduais da cidade de São Luís MA, no período de agosto a setembro de 2005. Aplicou-se um checklist para observar e avaliar as condições físicas da cozinha, limpeza e desinfecção dos equipamentos e utensílios, e as condutas das merendeiras durante o trabalho e o seu perfil sociocultural.
