“…The highest I/O ratio for bacteria count was observed in kindergartens (141.73), primary schools (128.06), and restaurants (32.54). Since the I/O ratio for airborne bacteria was higher than 1 in all of the sampling site groups, their major sources might be any activity done in such environments: the presence of human and pets, movement of textiles, and food products [3,7,10,34,44]. When we classified all indoor and outdoor bacteria levels into two different categories, the ANOVA test results showed that there was a significant difference between them (p a 0.001).…”

In this study, different types of indoor environments (primary school, kindergarten, cafeteria, restaurant, dormitory, dwelling, office, sport salon, library, classroom, and laboratory) and their outdoor environments were investigated in terms of bioaerosol contamination. A total of 120 environments were investigated in Ankara, Turkey. The single-stage Andersen sampler was used for viable bioaerosol sampling. During the sampling, indoor and outdoor temperature, relative humidity, and CO 2 concentration were measured. Total bacteria counts (TBC) and fungi concentrations varied on a large scale within and between the sampling site groups (10 -10 3 CFU/m 3 ). The highest TBC levels were measured in kindergartens, primary schools, restaurants, high schools, and homes, while the highest mold levels were measured in kitchens, bathrooms, and offices. Micrococcus spp., Staphylococcus auricularis, and Bacillus spp. were predominant bacteria species and Penicillium spp., Aspergillus spp., and Cladosporium spp. were the most observed mold genera detected in the samples. Indoor-to-outdoor (I/O) ratios of the observed fungi counts were calculated as approximately around 1, and for bacteria counts these ratios were higher than 1. There was no statistical difference between indoor and outdoor mold levels, while a significant difference was found between indoor and outdoor bacteria levels (p a 0.001). A significant correlation between indoor CO 2 and bioaerosols indicates insufficient ventilation.

RESUMOObjetivo: Avaliar a eficácia de hipoclorito 1% como um agente de desinfecção ambiental para controlar Acinetobacter em um hospital onde este microrganismo é endêmico. Métodos: Uma avaliação foi realizada em três diferentes períodos: 10 meses antes, durante 3 meses e 5 meses após a intervenção com a higienização do ambiente, usando hipoclorito de 1% em todas as unidades do hospital. Os dados sobre infecção (pneumonia, infecção do trato urinário e bacteremia) foram apresentados como número por 1000 pacientes-dia. Resultados: A taxa de infecção Acinetobacter eram 16,7 por 1000 pacientes-dia antes da intervenção, 5,1 por 1000 pacientes-dia durante a intervenção e 25,0 por 1000 pacientes-dia de cinco meses após a intervenção de hipoclorito. A intervenção hipoclorito resultou numa redução significativa na infecção por Acinetobacter em todos os sítios (urinária, bacteremia e pneumonia) (p <0,05). Conclusão: hipoclorito foi eficaz na redução temporária da taxa de Acinetobacter infecção.Palavras--Chaves: Hipoclorito. Controle de Infecção. Infecção. Acinetobacter. Surto. ABSTRACTObjective: Evaluate the effectiveness of 1% hypochlorite as an environmental disinfection agent to control Acinetobacter infection in a hospital where this microorganism is endemic. Methods: An interventional prospective at three different periods: 10 months before, 3 months during and 5 months after intervention with environmental hygienization using 1% hypochlorite in all units of the hospital. The normal routine for infection control remained the same during the intervention. Data on infection (pneumonia, bacteremia and urinary tract infection) were presented as number per 1000 patient-days. Results: The rate of Acinetobacter infection were 16.7 per 1000 patient-days before intervention, 5.1 per 1000 patient-days during intervention and 25.0 per 1000 patient-days five months after hypochlorite intervention. The hypochlorite intervention resulted in a significant reduction in Acinetobacter infection, including all sites (urinary, bacteremia and pneumonia) (p < 0.05). Conclusion: Hypochlorite was effective in reducing the rate of Acinetobacter infection during the disinfection.

Privacy curtains, frequently used in hospitals to separate patient care areas may have an important role in the transmission of healthcare-associated pathogens. In this pilot study, we inoculated curtain swatches with suspensions of clinical specimens of meticillin resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus (VRE), and Clostridium difficile before using a gloved hand to touch the inoculated curtain swatch and transfer to clean agar plates. Three different commonly used disinfectants were then sprayed onto these swatches before using a clean gloved hand to touch the swatch and transfer onto new agar plates. All plates were incubated at 35°C for 24 and 72 h. Bacterial growth before and after disinfection was assessed and compared. 3.1% hydrogen peroxide effectively eliminated transfer of C. difficile, MRSA and VRE from inoculated curtains.
