Abstract

Objectives: To monitor the environment in specific areas of three tertiary hospitals in Fortaleza - CE, seeking to report the presence of potentially pathogenic fungi for patients and staff, contributing to a better risk assessment in these hospitals.
Methods: In the period from December, 2005 to November, 2006, air samples from three public hospitals were collected monthly, which resulted in 180 air samples originated in 15 hospitals. The biological specimens were collected using the passive method of sedimentation, with exposure of Petri dishes containing Sabouraud agar supplemented with antibiotic. The dishes were incubated for 10 days (28°C) and all fungal colonies developed were subsequently identified.
Results: 10,608 colonies were isolated, belonging to 16 genera, the most common being Aspergillus check for this species in other resources , Penicillium check for this species in other resources , Candida check for this species in other resources , Curvularia check for this species in other resources and Trichoderma check for this species in other resources . There were no statistically significant relationships between the total number of colonies and the characteristics of each environment studied, except for three of those.
Conclusion: The difference in fungal concentrations in the air of these hospitals is possibly more related to instability of human activities, such as overpopulated settings and construction works, than to climatic variations observed in the period.

Resumo

Objetivos: Monitorar o ambiente em áreas específicas de três hospitais terciários da cidade de Fortaleza – CE, buscando relatar a presença de fungos potencialmente patogênicos para pacientes e funcionários, contribuindo para uma melhor avaliação de riscos nesses hospitais.
Métodos: No período de dezembro/2005 a novembro/2006, foram realizadas coletas mensais de amostras do ar de três hospitais públicos, que resultaram em 180 amostras de ar oriundas de 15 ambientes hospitalares. Os espécimes biológicos foram coletados através do método da sedimentação passiva, com exposições de placas de Petri, contendo ágar Sabouraud, suplementado com antibiótico. As placas foram incubadas por 10 dias (28°C), com a posterior identificação de todas as colônias fúngicas desenvolvidas.
Resultados: Isolaram-se 10.608 colônias, pertencentes a 16 gêneros, sendo os mais frequentes Aspergillus check for this species in other resources , Penicillium check for this species in other resources , Candida check for this species in other resources , Curvularia check for this species in other resources e Trichoderma check for this species in other resources . Não se observaram relações estatisticamente significativas entre o número total de colônias e as características de cada ambiente analisado, com exceção de três ambientes.
Conclusão: A diferença na concentração fúngica do ar desses hospitais possivelmente está mais relacionada com desequilíbrios das atividades humanas, tais como ambientes superpovoados e obras de construção, do que com as variações climáticas observadas no período em análise.
