The Trade in Medicinal Animals in Northeastern Brazil

Over the centuries, a significant part of the Brazilian fauna is widely sold, more specifically in retail stores or street markets. The objective was to characterize the sale of medicinal animals in five large northeast cities. Information about the sale of zootherapeutic items was obtained in the cities of Aracaju-SE, Fortaleza-CE, Maceio-AL, Recife-PE, and Salvador-BA. A total of 68 animal species were sold for medicinal purposes in the cities studied; these are the first results on the use and sale of zootherapeutics in the markets of Aracaju, Fortaleza, and Salvador and first recorded on the medicinal use of the Achatina fulica, Trachycardium muricatum, Philodryas olfersii, Desmodus rotundus, and Leptodactylus vastus. Knowledge of the fauna utilized popular medicine is indispensable for conservation, demonstrating that research on this subject is necessary to determine appropriate practices for the management of the fauna

Atividade moduladora de extratos etanólico e hexânico de raiz de Costus cf. arabicus sobre drogas antimicrobianas

The bacterium Escherichia coli is known to produce enterotoxins causing diarrheal diseases. Some species of Staphylococcus are recognized as etiological agents of many animal and human opportunistic infections. Pseudomonas aeruginosa is the main cause of nosocomial infections, mainly affecting immunocompromised patients. Candidiasis is the most frequent opportunistic mycosis, frequently caused by Candida albicans, C. tropicalis, C. parapsilosis, C. glabrata, and C. krusei. Medicinal plants have been the source of many remedies used in the clinical practice. In this study, the hexane and methanol extracts of Costus cf. arabicus were assayed to the antibacterial activity alone or associated with aminoglycosides and antifungal drugs. Synergism of the ethanol and hexane were verified by the microdilution method. A synergistic effect of the two extracts combined with the aminoglycosides and antifungal agents was demonstrated. It is therefore suggested that the extracts from Costus cf. arabicus could be used as a source of natural products with resistance-modifying antimicrobial activity, providing a new mechanism against the problem of bacterial and fungal resistance to drugs.A bactéria Escherichia coli é conhecida por produzir enterotoxinas capazes de causar diarréia. Algumas espécies de Staphylococcus são agentes etiológicos de muitas infecções oportunistas em animais e humanos. Pseudomonas aeruginosa é a principal causa de infecções hospitalares, acometendo principalmente pacientes imunocomprometidos. Candidíase é a micose oportunista mais comum, muitas vezes causada por Candida albicans, C. tropicalis, C. parapsilosis, C. glabrata e C. krusei. As plantas medicinais têm sido a fonte de muitos remédios tradicionais aplicados na prática clínica. Neste trabalho, os extratos hexânico e etanólico de Costus cf. arabicus foram testados quanto a sua atividade antibacteriana de forma isolada e em combinação com aminoglicosídeos e antifúngicos. O sinergismo dos extratos etanólico e hexânico foi verificado pelo método de microdiluição. Foi observado um efeito sinérgico de ambos os extratos quando combinados com os aminoglicosideos e antifúngicos. Sugere-se, portanto, que os extratos de Costus cf. arabicus poderiam ser usados como uma fonte de produtos naturais com atividade modificadora de resistência a drogas antimicrobianas, fornecendo um novo mecanismo contra o problema da resistência bacteriana e fúngica a drogas

Chemical Composition and Validation of the Ethnopharmacological Reported Antimicrobial Activity of the Body Fat of Phrynops geoffroanus

Background. Phrynops geoffroanus is a small turtle that inhabits lakes, rivers, and streams throughout South America. The body fat of this animal is used as a folk medicine in Brazil for treating illnesses such as sore throats, ear aches, mumps, rheumatism, and arthritis. The present study evaluated the antimicrobial activity of oil extracted from Phrynops geoffroanus (OPG), determined its chemical composition, and discussed the implications of its use in traditional medicine. The OPG was obtained from the ventral region of this turtle using hexane as a solvent. The antimicrobial activity of OPG was tested against standard and multiresistance strains of bacteria and fungi and its composition was determined indirectly by analyzing the methyl esters of the component fatty acids. The OPG presented a clinically relevant antifungal activity against Candida krusei ATCC 6258 (MIC 128 µg/mL). When the OPG was associated with the antibacterial and antifungal drugs, was observed a synergistic effect when associated the OPG with the gentamicin against the strain Pseudomonas aeruginosa 22. Our results indicated that OPG has clinically relevant antifungal activity against C. krusei, and demonstrated synergetic antibacterial activity in combination with commercial antibiotics against Pseudomonas aeruginosa

UPLC-MS-QTOF analysis and antifungal activity of Cumaru (Amburana cearensis).

This study was aimed at investigating the phytochemical constituents, antifungal properties and antibiotic-modifying activity of the aqueous crude extract and fractions of Amburana cearensis seeds (CEFAC). The CEFAC were chemically characterized by LC–MS/MS–QTOF. In addition, the antifungal activity was assayed by the microdilution method against strains of Candida albicans. The phytochemical profile of CEFAC exhibited phenolic compounds, organic acids, and polyphenols. The results of the assessment of antifungal activity reveled an IC(50) ranging from 45.6 to 2048 µg/mL. Interestingly, when CEFAC was associated with Fluconazole, we evidenced a decreased IC(50) (1.81–11.9 µg/mL), suggesting a synergism with antibiotic. It was possible to identify in the crude extract and fractions several phenolic compounds, organic acids, and some polyphenols in positive ionization mode. These results suggest that CEFAC may present compounds with the ability to interact and act synergistically with antimicrobial drugs, highlighting its potential as an alternative source for the development of new antimicrobial agents

Repercussões do Sars-Cov-2 no âmbito da cirurgia geral e medicina de emergência: uma revisão

Na China, em dezembro de 2019, foram relatados os primeiros casos da patologia respiratória  COVID-19, doença causado pelo SARS-CoV-2, um RNA vírus. A propagação foi veloz e global, de maneira que a Organização Mundial de Saúde definiu como pandemia em março de 2020. A doença tem manifestação clínica variada, com enfermos assintomáticos ou manifestando quadro crítico, apresentando alta transmissibilidade e letalidade considerável. Simultaneamente, indivíduos com indicação cirúrgica, de origem traumática ou não, tiveram seus atendimentos eletivos paralisados e houve queda nos índices de intervenções de cunho emergencista, tanto devido o medo do indivíduo procurar um serviço de saúde e ser contaminado pelo coronavírus, quanto por outros fatores. Essa revisão teve como objetivo averiguar como a pandemia acometeu serviços de cirurgia geral de emergência, bem como elucidar os preditores e fatores que ocasionaram mudanças no manejo e intervenções cirúrgicas durante o surto de SARS-CoV-2
