Isolation of pathogenic yeasts in the air from hospital environments in the city of Fortaleza, northeast Brazil

The Brazilian Journal of Infectious Diseases (2010)

Rossana de Aguiar Cordeiro Raimunda Sâmia Nogueira Brilhante Lydia Dayanne Maia Pantoja Renato Evando Moreira Filho P. R. N. Vieira

This paper reports the results of environmental surveillance of yeasts in specific areas of two tertiary local hospitals. From March 2007 to February 2008, samples from the air of two public hospitals were collected on a monthly basis. The samples were collected through passive sedimentation method (day and night exposure) of Petri dishes. A total of 240 air samples from 10 hospital environments were analyzed. These environments presented similar contamination levels, from which 80 fungi isolates were isolated: Candida parapsilosis (n = 34), Rhodotorula spp. (19), Trichosporon asahii (11), C. tropicalis (8), C. albicans (4), C. glabrata (1), C. guilliermondii (1), C. krusei (1) and Saccharomyces spp. (1). Regarding the presence of yeasts and climatic conditions, there were 40 strains (50%) in semi-critical areas (natural ventilation) and critical areas (air conditioned). Considering the presence of microorganisms with pathogenic potential, environmental monitoring is necessary to prevent possible hospital infections.

In vitro study of essential oils encapsulated in chitosan microparticles against Histoplasma capsulatum and their pathogenicity in Caenorhabditis elegans

Biofouling (2025)

Anderson da Cunha Costa Mirele Rodrigues Fernandes Augusto Feynman Dias Nobre Maria Gleiciane Rocha Jacó Ricarte Lima de Mesquita

Histoplasmosis, caused by Histoplasma capsulatum, poses risks for immunocompromised individuals. With limited therapeutic options, this study explores microparticles as antimicrobial delivery systems for Cymbopogon flexuosus and Pelargonium graveolens essential oils against H. capsulatum. The broth microdilution assay showed MICs of 32 to 128 µg/mL in filamentous phase and 8 to 64 µg/mL in yeast phase. Combining microparticles with antifungal drugs demonstrated synergistic effects in both filamentous and yeast-like forms with amphotericin B or itraconazole. Chitosan microparticles reduced H. capsulatum biofilm biomass and metabolic activity by about 60% at 512 µg/mL. In vivo evaluation with Caenorhabditis elegans showed H. capsulatum caused over 90% mortality. These findings highlight the potential use of chitosan microparticles as a delivery system for essential oils against H. capsulatum, especially in combination with other compounds.

Antifungal susceptibility of emerging opportunistic yeasts and yeast-like fungi from Rhea americana

Canadian Journal of Microbiology (2013)

Rossana de Aguiar Cordeiro Lucas Pereira de Alencar Raimunda Sâmia Nogueira Brilhante Débora de Souza Collares Maia Castelo‐Branco Carlos Eduardo Cordeiro Teixeira

Opportunistic yeasts and yeast-like fungi have been recognized as important pathogens in high-risk patients. This study aimed to evaluate the presence of these microorganisms in the microbiota of captive rheas and to investigate the antifungal susceptibility of the isolated strains. Isolates representing Magnusiomyces capitatus (Geotrichum capitatum, n = 11), Trichosporon mucoides (n = 11), Trichosporon asteroides (n = 5), Rhodotorula mucilaginosa (n = 4), Trichosporon asahii (n = 3), Trichosporon cutaneum (n = 3), and Trichosporon ovoides (n = 3) were obtained from the oropharynx, cloaca, and feces of 58 animals. Most of the isolates were susceptible to antifungals in vitro; however, resistance against fluconazole (n = 1) and itraconazole (n = 2) was detected among T. mucoides. This study indicates that healthy rheas can be reservoirs of opportunistic pathogens. Primary resistance to azoles in T. mucoides obtained from these animals demonstrates the potential risk to humans.

A Virtual Game-Based Tournament to Engage Students in Reviewing Organic Acids and Bases Concepts

Journal of Chemical Education (2022)

José Nunes da Silva Dávila Zampieri Antonio José Melo Leite Francisco Serra Oliveira Alexandre Jean‐Yves Winum

A virtual Game-Based Tournament of Chemistry was developed as an alternative to the traditional problem-solving classes to aid students in reviewing and understanding organic acidity and basicity concepts. The tournament was based on a multilingual virtual board game (English, Portuguese, French, and Italian) which aimed to facilitate students' interaction and collaborative learning in an enjoyable activity. The findings showed that students who participated in the tournament had better outcomes in the exams compared to those who partook in traditional problem-solving classes.

A Clinical Multicenter Study of Orofacial Features in 26 Brazilian Patients with Different Types of Mucopolysaccharidosis

The Cleft Palate-Craniofacial Journal (2014)

Erlane Marques Ribeiro Cristiane Sá Roriz Fonteles Adriana Bezerra Freitas Karla Shangela da Silva Alves André Jalles Monteiro

Purpose This study aimed to describe the orofacial features of 26 unrelated Brazilian patients with mucopolysaccharidosis and to verify any possible associations between these findings and specific types of mucopolysaccharidosis. Methods Patients were diagnosed with mucopolysaccharidosis and clinically evaluated. Following consent, a clinical assessment form was completed. Facial and intraoral examination was performed by evaluating facial pattern, malocclusions, dental caries, and tooth identification. Results Midface deficiency, increased lower facial third, anterior open bite, convex profile, macroglossia, gingival enlargement, and spaced arches were the most frequently observed features. These findings did not allow a differential diagnosis among the different types of mucopolysaccharidosis, except for pitting enamel, which significantly associated with mucopolysaccharidosis IVA ( P < .001). Open bite was associated with mucopolysaccharidosis types I, II, III, and VI; however, only one patient with mucopolysaccharidosis IVA expressed this feature ( P = .043). Conclusions Our results suggest that pitted enamel in patients with mucopolysaccharidosis is most likely a feature of mucopolysaccharidosis type IVA; whereas, open bite is rarely observed in these patients. Orofacial features in mucopolysaccharidosis may help pediatric dentists recognize this disorder and minimize the delay between the initial signs/symptoms and diagnosis of the disease. Future studies should focus on the longitudinal manifestations, expression, and severity of mucopolysaccharidosis-associated orofacial anomalies.

Parainfluenza virus infections in a tropical city: clinical and epidemiological aspects

The Brazilian Journal of Infectious Diseases (2008)

Mariana Mota Moura Fé André Jalles Monteiro Fernanda Edna Araújo Moura

Little information on the epidemiology and clinical characteristics of human parainfluenza virus (HPIV) infections, especially in children from tropical countries, has been published. The aim of this study was to determine the frequency of HPIV infections in children attended at a large hospital in Fortaleza in Northeast Brazil, and describe seasonal patterns, clinical and epidemiological characteristics of these infections. From January 2001 to December 2006, a total of 3070 nasopharyngeal aspirates collected from children were screened by indirect immunofluorescence for human parainfluenza viruses 1, 2, and 3 (HPIV-1, 2 and 3) and other respiratory viruses. Viral antigens were identified in 933 samples and HPIV in 117. The frequency of HPIV-3, HPIV-1 and HPIV-2 was of 83.76%, 11.96% and 4.27%, respectively. Only HPIV-3 showed a seasonal occurrence, with most cases observed from September to November, and with an inverse relationship to the rainy season. Most HPIV-3 infections seen in outpatients were diagnosed as upper respiratory tract infections.

Maria Naires Alves de Souza André Jalles Monteiro

Nos tempos atuais vivencia-se uma revolucao da tecnologia, da comunicacao e da informacao. Essa revolucao tem afetado a educacao, as instituicoes de ensino superior, a pratica docente, bem como seu relacionamento com os discentes. Com este estudo objetiva-se investigar como os docentes de graduacao da Universidade Federal do Ceara fazem uso da ferramenta de tecnologia da informacao e comunicacao denominada Portal Docente integrante do Sistema de Gestao de Atividades Academicas (SIGAA). Trata-se de uma pesquisa exploratoria descritiva na qual os dados principais foram coletados no banco de dados da instituicao. Conforme verificado, o Portal Docente detem precario uso pelos docentes de graduacao da UFC, porem com crescimento gradual de uso a cada semestre letivo. Inexiste correlacao significativa entre a quantidade de arquivos postados e a idade do docente. Deste modo, alguma iniciativa devera ser implementada pela administracao superior da universidade para uma efetiva ampliacao da sua utilizacao.

Antiretroviral drugs saquinavir and ritonavir reduce inhibitory concentration values of itraconazole against Histoplasma capsulatum strains in vitro

The Brazilian Journal of Infectious Diseases (2015)

Raimunda Sâmia Nogueira Brilhante Érica Pacheco Caetano Giovanna Barbosa Riello Gláucia Morgana de Melo Guedes Débora de Souza Collares Maia Castelo‐Branco

Recent studies have shown that some drugs that are not routinely used to treat fungal infections have antifungal activity, such as protease inhibitor antiretroviral drugs. This study investigated the in vitro susceptibility of Histoplasma capsulatum var. capsulatum to saquinavir and ritonavir, and its combination with the antifungal itraconazole. The susceptibility assay was performed according to Clinical and Laboratory Standards Institute guidelines. All strains were inhibited by the protease inhibitor antiretroviral drugs. Saquinavir showed minimum inhibitory concentrations ranging from 0.125 to 1μgmL(-1) for both phases, and ritonavir presented minimum inhibitory concentrations ranging from 0.0312 to 4μgmL(-1)and from 0.0625 to 1μgmL(-1) for filamentous and yeast phase, respectively. Concerning the antifungal itraconazole, the minimum inhibitory concentration values ranged from 0.0019 to 0.125μgmL(-1) and from 0.0039 to 0.0312μgmL(-1) for the filamentous and yeast phase, respectively. The combination of saquinavir or ritonavir with itraconazole was synergistic against H. capsulatum, with a significant reduction in the minimum inhibitory concentrations of both drugs against the strains (p<0.05). These data show an important in vitro synergy between protease inhibitors and itraconazole against the fungus H. capsulatum.

Revista da Sociedade Brasileira de Medicina Tropical (2004)

Marília Dutra Girão Marilena R. Prado Raimunda Sâmia Nogueira Brilhante Rossana de Aguiar Cordeiro André Jalles Monteiro

A manutenção de culturas de Malassezia pachydermatis em micotecas é importante para estudos retrospectivos e prospectivos. O objetivo deste trabalho foi avaliar o comportamento de Malassezia pachydermatis frente a diferentes métodos de conservação de culturas. Para tanto, após o processo de identificação, essa levedura foi estocada, por seis e nove meses, em salina e salina com óleo mineral a 28°C, bem como, em ágar Dixon, ágar Dixon acrescido de glicerol e ágar Dixon acrescido de dimetil-sulfóxido (DMSO) a -20°C. Os meios de Dixon e Dixon acrescido de glicerol foram os métodos mais adequados (p< 0,05) para manter a viabilidade das cepas, em seis e nove meses de estoque. Qualquer dos métodos utilizados foi conveniente para manutenção da positividade na prova da urease em seis meses de estocagem, sendo o ágar Dixon e o ágar Dixon acrescido de glicerol, os melhores (p< 0,05) para nove meses. Portanto, para a recuperação e manutenção das características de Malassezia pachydermatis, recomenda-se o emprego do meio de Dixon ou do meio de Dixon acrescido de glicerol.
