Abstract
RESUMO Listeria monocytogenes é o agente causador da listeriose, uma grave doença de origem alimentar que causa severas infecções em humanos com altas taxas de mortalidade. O leite e seus derivados estão entre os produtos alimentícios mais frequentemente envolvidos na transmissão de L. monocytogenes. A listeriose acomete, sobretudo, indivíduos imunodeprimidos, grávidas, recém-nascidos e idosos, o que ressalta o caráter oportunista deste micro-organismo e sua importância para a saúde pública. No presente trabalho, faz-se uma revisão narrativa crítica sobre o risco à saúde humana decorrente da ingestão de leite e derivados contaminados por L. monocytogenes, bem como se discutem os fatores que determinam a contaminação por L. monocytogenes na cadeia de produção e distribuição de leite e derivados. São apresentados e avaliados os dados de ocorrência de L. monocytogenes em leite cru e em produtos lácteos no Brasil, tendo em vista seu potencial de envolvimento em casos de listeriose humana. Adicionalmente, são indicadas as principais áreas de pesquisa e atuação para prevenir a contaminação de L. monocytogenes em produtos lácteos.

Abstract
We present a case of subcutaneous hyalohyphomycosis due to Acremonium recifei, a species whose habitat is probably the soil, first identified in 1934 by Arêa Leão and Lobo in a case of podal eumycetoma with white-yellowish grains and initially named Cephalosporium recifei. A white immunocompetent female patient from the state of Bahia, Brazil, with a history of traumatic injury to the right hand is reported. The lesions was painless, with edema, inflammation and the presence of fistulae. Seropurulent secretion with the absence of grains was present. Histopathological examination of material stained with hematoxylin-eosin showed hyaline septate hyphae. A culture was positive for Acremonium recifei. Treatment with itraconazole, 200 mg/day, for two months led to a favorable course and cure of the process. We report for the first time in the literature a case of subcutaneous hyalohyphomycosis due to Acremonium recifei in a immunocompetent woman. Treatment with itraconazole 200 mg/day, for two months, resulted in cure.

Abstract
We report three cases of subcutaneous phaeohyphomycosis due to Exophiala jeanselmei (Langeron) McGinnis et Padhye 1977, in kidney transplant patients. Exophiala jeanselmei is a dematious fungus having also ability to rarely procedure eumycetoma (black grains). According to KWON-CHUNG & BENNETT (1992) such fungus is antigenically very heterogeneous, since so far three serotypes have been identified; each serotype including subgroups. Subcutaneous phaeohyphomycosis is becoming more and more frequent in kidney transplant patients submitted to an immunosuppressive treatment. As Exophiala jeanselmei has already been isolated from the environment it becomes difficult to explain the pathogenicity of these cases by a reactivation of quiescent processes. The authors suggest an occasional fungistatic action of cyclosporine A upon Exophiala jeanselmei.

Abstract
A case of rhinofacial zygomycosis with of years duration, caused by Conidiobolus coronatus is described. The patient, a 72-years-old woman, presented with a bilateral distortion of the subcutaneous tissue and disfigurement of the face. Treatment with ketoconazole and potassium iodide did not prevent several relapses. At present she is still under treatment with fluconazole with clinical healing. Histopathological and mycological examination confirmed the dermatological diagnosis. An increasing number of cases of zygomycosis caused by fungi of the order Entomophthorales have also been reported in the Northern and Northeastern States of Brazil.

Abstract
A case of phaeohyphomycosis caused by Bipolaris hawaiiensis is reported. The patient, an immunocompetent host, presented a verrucous lesion on the first finger of the left foot. Dematiaceous septate hyphae and yeast-like elements were seen in direct and histological examination. The isolated strain was identified on the basis of micro and macromorphological aspects. Treated with electrocoagulation, the lesions healed and presented no relapse after two years follow-up.

Abstract
The authors report a case of subcutaneous mucormycosis in a diabetic patient with verrucous lesions in the fourth finger of the right hand. Initially diagnosed as a fixed cutaneous sporotrichosis case, success was obtained with the use of potassium iodide with healing of the lesion in a period of nearly 5 months. At present the patient remains under clinical observation with no treatment or relapse.

Abstract
Objetivou-se isolar e identificar a microbiota fúngica em ambientes considerados assépticos, através de exposições com meios de cultivo adequados, em três épocas distintas do ano, antes e imediatamente após as manobras técnicas realizadas em três áreas de trabalho: ambiente aberto, ambiente fechado sem filtração de ar e ambiente fechado com filtração de ar, utilizadas em produção de imunobiológicos. Os meios ágar-Sabouraud e ágar-soja, enriquecidos com 0,2% de extrato de levedura e sem cloranfenicol, foram estudados quanto à sua eficácia no isolamento de bolores e leveduras, considerando-se o número de colônias desenvolvidas e a freqüência dos diversos fungos isolados. Isolaram-se 67 espécimens, sendo 64 fungos filamentosos (bolores) e três leveduras. Dos bolores, 54 pertenciam a 22 gêneros da divisão Deuteromycota, famílias Moniliaceae e Dematiaceae, cinco amostras filamentosas foram incluídas na ordem Agonomycetales (Mycelia Sterilia), e uma amostra foi classificada na divisão Deuteromycota, ordem Sphaeropsidales, classe Coelomycetes. Da divisão Zygomycota, ordem Mucorales, família Mucoraceae, um único mucoráceo foi identificado até gênero. As três leveduras pertenciam também à divisão Deuteromycota (Fungi Imperfecti), família Cryptococcaceae, e foram identificadas como sendo duas Rhodotorula rubra e uma Torulopsis candida. Comprovou-se que o número de colônias isoladas aumentou após a realização das monobras técnicas e que a filtração de ar através de filtros tipo HEPA, reduzindo o número de colônias isoladas nos ambientes fechados, aumenta a segurança do trabalho; comumente é recomendada para áreas de atividade técnica cujos resultados satisfatórios estão diretamente relacionados com uma baixa incidência de contaminantes.

Abstract
The Authors present a case of subcutaneous mucormycosis occurring in a patient with clinical and biochemical evidence of diabetic ketoacidosis. The clinical, mycological and histopathological features are described, emphasizing the relevance of a rapid diagnosis in order to stablish early treatment. The clinical forms of mucormycosis and the main associated conditions are briefly reviewed as well as the most probable conditions which may lead to the enhanced susceptibility to infection in the diabetic patient in ketoacidosis. The recovery of Rhizopus oryzae from the air of the room of the patient suggests a nosocomial infection acquired through contamination of venous puncture site by air borne spores.
