Item Teste de sensibilidade ao Amitraz e Deltametrina em Rhipicephalus sanguineus Sensu Latona região metropolitana de Manaus(Universidade Brasil, 2021) Oliveira, Rafael Justa de; Soares, Vando EdésioThe tick Rhipcephalus sanguineus is an acari that has great impact on veterinary medicine, because it acts as a vector of many diseases in animals and even in humans, in which case it has been parasitized by this acari. Some active principle has been used in an effort of control this parasite, however its continuous use can end up causing resistence in this acari, resuting in hard control. Some authors already reported resistance of this and others ticks in some places in Brazil. Although, little it is known about the resistance of R. sanguineus to the active principle commonly used. The objective of this research was to test the resistance of R. sanguineus to two active principles most used as tick control: Amitraz and Deltamethrin. Thus, a population of 90 females parthenogynous was used after being taken from 46 parasitized dogs collected from donor collections from all areas of Manaus -AM. The parthenogynous where than divided in 3 groups. Group 1 was exposed to amitraz, group 2 was exposed to Deltamethrin and group 3 was exposed to distilled water. By the end of 15 days of experiment twenty-five individuals of group 1 died (83,3%) and five survived (16,7%), although they didn’t lay eggs; 100% of the individuals of group 2 died; all individuals of group 3 survived and they laid eggs. This experiment showed that the active principles tested were effective in the control of this parasite, since even in group, individuals who have survived the test failed to lay eggs, making it impossible to finish the biological cycle.Item Avaliação dos testes de resistência em luvas de látex utilizadas em procedimentos odontológicos.(Universidade Brasil, 2024) Beserra, Leidiana Viana; Costa, Mardoqueu Martins daIn clinical practice, professional activities are subject to various occupational risks, among which biological risks stand out for involving pathogens such as bacteria, fungi, protozoa, viruses, and parasites. These agents can invade the body via cutaneous, digestive, and/or respiratory routes, manifesting according to the individual’s immune response. To ensure safe practice and minimize potential contamination, biosafety measures include adopting rigorous protocols and using Personal Protective Equipment such as latex gloves. However, these products can present variations in quality and mechanical resistance among different brands, which compromises the safety of professionals and patients. Therefore, this study aimed to evaluate the quality of latex procedure gloves used in dental clinics, focusing on their mechanical resistance and impermeability. Four brands were analyzed through visual inspection and integrity testing, impermeability testing, and tensile strength tests, which made it possible to determine the maximum force, maximum tension, and elongation before rupture. Dimensional tests revealed no significant difference in glove length among the manufacturers, and width remained consistent, with no notable differences between brands A and D. In the impermeability test, deformation was observed in all brands, with gloves A and B showing no tears, while gloves C had multiple holes and gloves D exhibited leakage near the cuff. Regarding tensile strength, a good stretching capacity before rupture was found, with a maximum force ranging from 12.16 N to 17.94 N (mean of 14.86±2.45 N) and a maximum tension ranging from 38.30 MPa to 56.52 MPa (mean of 46.81±7.76 MPa). Elongation values ranged from 907.04% to 1137.21%, with a mean of 1037.32±89.20%, indicating differences in performance among the analyzed brands and underscoring the importance of carefully selecting products with proven quality control. It is concluded that significant differences exist in terms of impermeability and mechanical resistance of latex gloves, emphasizing the need for a thorough evaluation of these materials to ensure the safety of professionals and patients, thereby helping reduce biological risks in clinical practice and serving as a basis for future research on the quality of this personal protective equipment.Item Perfil de sensibilidade microbiana in vitro de cepas de escherichia coli e klebsiella pneumoniae isoladas de queijo artesanal = in vitro microbial sensitivity profile of strains of escherichia coli and klebsiella pneumoniae isolated of artistical cheese.(Universidade Brasil, 2018) Neres, Liberta Lamarta Favoritto Garcia; Andreani, Dora Inês KozusnyItem Incidência de Staphylococcus multirresistentes a antimicrobianos nas mãos dos profissionais de unidade básica de saúde(Universidade Brasil, 2017) Silva, Ana Elisa Pereira da; Kozusny-Andreani, Dora Inés
