“…Therefore, the presented study is aimed at detecting airborne fungi in the environment of different areas of two hospitals (1 and 2) to illustrate the occurrence of fungal species. The results obtained are in accordance with the results of other aeromycology studies from Mexico and Brazil [36][37][38].…”

“…The fungal burden found in the sampled areas of the two hospitals is inconsistent with that reported in other countries [28,29]; however, the CFU/m 3 in the operating theatre is consistent with such reports (5-10 CFU/m 3 ), which can be explained by the stringent hygienic measures in operating theatres. Similarly, there are no established criteria at the institutional level in Mexico regarding the ranges of CFU/m 3 that are considered acceptable, since only one study of this type has been reported [38]. The homogeneity in the number of CFU/m 3 found during the two seasons (rainy and dry) can be explained by the similarity between these season in Mexico City, compared with countries of North America and Europe, where seasons are marked by abrupt changes in ambient temperature and a true separation occurs between intramural and extramural environments, which does not happen in Mexico.…”

Introduction and objective. Nosocomial invasive fungal infections, particularly aspergillosis, are an increasing problem in immunocompromised patients. The presented study evaluates fungal diversity and the presence of Aspergillus in air samples from two hospitals. Materials and methods. Over the course of one year (rainy and dry seasons), the air was sampled from three areas in two hospitals (1 and 2) using a single-stage Andersen viable particle sampler (Thermo Scientific, Waltham, MA, USA). The fungi were identified by macro-and micromorphology, and the number of colony forming units (CFU)/m 3 air and their richness, abundance, and diversity were determined. Isolates Aspergillus genus were characterized by their thermotolerance. Results. The CFU/m 3 air was similar at both hospitals during the two seasons, but different between the sampled areas. Results showed 10 fungal genera for hospital 1, and 8 for hospital 2. The most abundant were Penicillium, Cladosporium and Aspergillus. The thermotolerance test confirmed the identification of A. fumigatus section Fumigati. The highest growth rate was found in Aspergillus section Nigri. Conclusion. Determining the fungal diversity in the two hospitals was important because all the species have the potential to be pathogenic, especially the section Fumigati.

“…However, none of the studies were conclusive about the role of air microflora in nosocomial infection in the Intensive Care Unit (ICUs), especially if it is multidrug resistant (MDR). So far, very few studies had been done in the ICU environment such as Ríos-Yuil et al [5] mentioned about the presence of various nosocomially significant fungus in the ICU of a general hospital and Huang et al [6] tried to find out the potential correlation between airborne and surface contamination in two ICUs of Taiwan, and whether patient infections were related to microbial contamination in the ICU. Based on the limited background knowledge about microbial contamination of the ICU environment and their contribution to nosocomial infection in the ICU, the main objectives of this study were microbiological characterization of the air samples in relation to the nosocomial infections in the different ICUs at different periods in our tertiary care hospital.…”

ResumenEl objetivo de este estudio fue detectar el hongo alergénico Cladosporium en la atmósfera de la Plaza San Martín de Lima (Perú) y analizar la influencia de las variables meteorológicas sobre su concentración. El muestreo del aire se ha realizado utilizando un equipo de impacto volumétrico tipo Andersen de una sola etapa. Se observó que los conidios de Cladosporium estuvieron presentes en la atmósfera durante todo el período de estudio, sin embargo, las concentraciones más altas se observaron en los meses de marzo y septiembre. Se ha encontrado una correlación estadística positiva entre la concentración de conidios de Cladosporium y la velocidad del viento e índice UV. El efecto de la temperatura del aire presentó una débil correlación positiva sobre la concentración de Cladosporium a diferencia de la humedad relativa que presentó una correlación negativa. La identificación de los factores climáticos que favorecen la liberación de conidios puede mejorar significativamente los métodos actuales de prevención de la alergia, la detección temprana de infecciones en plantas o enfermedades respiratorias en humanos. Palabras clave: bioaerosol, conidios, esporas, alergia, variables climáticas. AbstractThe objective of this study was to detect the allergenic fungus Cladosporium in the atmosphere of the Plaza San Martín of Lima (Perú) and to analyze the influence of the meteorological variables on its concentration. Air sampling was performed using a one-stage Andersen type volumetric impact equipment. Cladosporium conidia are present in the atmosphere of Plaza San Martín throughout the study period, however, the highest concentrations were observed in the months of March and September. A positive statistical correlation was found between the concentration of Cladosporium conidia and the wind speed and UV index. The effect of the air temperature showed a weak positive correlation on the concentration of Cladosporium, however, the relative humidity presented a negative correlation. Identification of climatic factors favoring the release of conidia may improve current methods of allergy prevention, early detection of plant infections or respiratory diseases in humans.
