Item Bioaerossóis e seus riscos à saúde ambiental em um pet shop(Universidade Brasil, 2023) Leal, Rosimeire Aparecida da Silva; Vazquez, Gisele Herbst; Kozusny-Andreani, Dora InésOccupational exposure to cats and dogs can cause respiratory symptoms in veterinarians and attendants. Research carried out in pet stores indicates microbiological contamination of the air through exposure to bioaerosols. The objective of this study was to analyze the presence of microorganisms in bioaerosols from a pet shop in Fernandópolis/SP. On days 21, 23 and 25/11/2022, air samples were collected by exposing Petri dishes containing culture media open for 30 min at 1.5 m from the floor, in the central part of the work room, before, during and after dog bathing, grooming and drying procedures. The plates were incubated at 37oC for 24-48h for the growth of bacteria and yeasts, after which Colony Forming Units - CFU were counted and identified using conventional biochemical methods. During the bathing and grooming of the animals, the microbial community in the air was quantitatively higher and qualitatively different from those at the beginning and end of the procedure, a fact that was repeated on the three days of analysis. The results indicated resistance of Staphylococcus aureus to the antibiotics Ceftazidine, Tobramycin, Penicillin, Oxacillin and Erythrominin greater than 80% and 100% sensitive to Amikacin. It was concluded that the bioaerosols from the evaluated pet shop present high contamination by microorganisms (Candida albicans, Staphylococcus aureus, Micrococcus sp, Bacillus sp and Escherichia coli) produced mainly during bathing, grooming and drying of dogs, which raises concerns regarding the risk of disease transmission by these pathogens to the animals treated and to humans who are on site and in direct contact with the bioaerosols and work equipment.Item Avaliação de fungos em bioaerossois em ambiente de um hospital de médio porte do noroeste paulista(Universidade Brasil, 2020) Teixeira, Bruna Perassoli; Kozusny-Andreani, Dora InésThe changes related to health environments have been the subject of many studies, because of the severity and negative impact that can compromise the recovery of the patient and the well-being of people in local and even the visitors of hospitalized people. This work aimed to evaluate the presence of microorganisms in bioaerosols in a medium-sized hospital in the northwest region of São Paulo, in two restricted locations: intensive care unit (ICU) and Central for Material and Sterilization (CMS). Air samples were collected at three strategic points, once a month, for six consecutive months comprising two different times: from 7 am to 7 pm and from 7 pm to 7 am of the following day. For fungal collection, the spontaneous sedimentation method was used, by Petri dishes placed in predetermined locations. The plates were closed, stored in an appropriate place and transported to the microbiology laboratory of Faculdade Brasil, in the city of Fernandópolis, where they were analyzed. For the identification of fungi, macro and microscopic morphological characteristics were used, as well as conventional biochemical methods. The colony-forming units were identified and accounted for, being analyzed statistically, through analysis of variance (ANOVA) and cluster analysis by hierarchical method. The following genera and species of fungi were found: Aspergillus fumigatus, Aspergillus niger, Candida albicans, Cladosporium spp, Curvularia spp, Fusarium spp, Penicillium spp, Rhizopus spp and Mucor spp. It was found that the daytime operation period is more prone to infections, since most of the colony-forming units developed between the hours of 7 am to 7 pm, which coincides with a greater presence of people in the place. The ICU was the place with the highest presence of microorganisms,Item Análise da acuidade auditiva em altas frequências e microbiológica dos plugs de ouvido em adolescentes.(Universidade Brasil, 2017) Giacheto, Fabiana Regina Sabion; Kozusny-Andreani, Dora Inés
