ABSTRACT

Sífilis é uma infecção sexualmente transmissível (IST) que sinaliza a necessidade de efetivas políticas públicas devido ao aumento de casos na última década. Dessa forma, o objetivo do trabalho é descrever a incidência de sífilis no estado do Rio de Janeiro e no município de Seropédica. Métodos: foi realizado um estudo descritivo, com abordagem quantitativa. A coleta dos dados foi realizada por meio do Sistema de Informação de Agravos de Notificação (Sinan), referentes ao município de Seropédica e ao estado do Rio de Janeiro, no período de 2010 a 2022. Resultados: foram identificados 105.138, 79.609 e 42.819 casos de sífilis adquirida, em gestantes e congênita, respectivamente, no estado do Rio de Janeiro e 187, 140 e 79 casos de sífilis adquirida, em gestantes e congênita, respectivamente, no município de Seropédica. Foi observado uma incidência maior para sífilis adquirida entre homens em comparação com mulheres tanto no estado do Rio de Janeiro (62.719 versus 42.346) quanto no município de Seropédica (110 versus 77). Houve um aumento nas taxas de incidência de sífilis no estado do Rio de Janeiro e no município de Seropédica ao longo dos anos. Conclusão: a sífilis segue sendo uma doença com alta incidência no território do Rio de Janeiro. Nesse sentido, é importante elaborar estratégias em saúde pública mais efetivas às pessoas acometidas por tal infecção.


Syphilis is a sexually transmitted infection (STI) that signals the need for effective public policies due to the increase in cases in the last decade. Thus, the aim of this study is to describe the incidence of syphilis in the state of Rio de Janeiro and in the municipality of Seropédica. Methods: a descriptive study with a quantitative approach was carried out. Data collection was performed through the Sistema de Informação de Agravos de Notificação (Sinan), referring to the municipality of Seropédica and the state of Rio de Janeiro, from 2010 to 2022. Results: overall, 105.138, 79.609 and 42.819 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the state of Rio de Janeiro, and 187, 140, and 79 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the municipality of Seropédica. A higher incidence of acquired syphilis was observed among men compared to women both in the state of Rio de Janeiro (62.719 versus 42.346) and in the municipality of Seropédica (110 versus 77). There has been an increase in the incidence rates of syphilis in the state of Rio de Janeiro and the municipality of Seropédica over the years. Conclusion: syphilis continues to be a disease with a high incidence in the territory of Rio de Janeiro. In this sense, it is important to develop more effective public health strategies for people affected by this infection.

ABSTRACT

Burn patients often face elevated pain, anxiety, and depression levels. Music therapy adds to integrative care in burn patients, but research including electrophysiological measures is limited. This study reports electrophysiological signals analysis during Music-Assisted Relaxation (MAR) with burn patients in the Intensive Care Unit (ICU). This study is a sub-analysis of an ongoing trial of music therapy with burn patients in the ICU. Electroencephalogram (EEG), electrocardiogram (ECG), and electromyogram (EMG) were recorded during MAR with nine burn patients. Additionally, background pain levels (VAS) and anxiety and depression levels (HADS) were assessed. EEG oscillation power showed statistically significant changes in the delta (p < 0.05), theta (p = 0.01), beta (p < 0.05), and alpha (p = 0.05) bands during music therapy. Heart rate variability tachograms high-frequencies increased (p = 0.014), and low-frequencies decreased (p = 0.046). Facial EMG mean frequency decreased (p = 0.01). VAS and HADS scores decreased - 0.76 (p = 0.4) and - 3.375 points (p = 0.37) respectively. Our results indicate parasympathetic system activity, attention shifts, reduced muscle tone, and a relaxed state of mind during MAR. This hints at potential mechanisms of music therapy but needs to be confirmed in larger studies. Electrophysiological changes during music therapy highlight its clinical relevance as a complementary treatment for ICU burn patients.Trial registration: Clinicaltrials.gov (NCT04571255).

ABSTRACT

BACKGROUND: Chagas disease is a risk factor for ischemic stroke, which causes high mortality rates and significant disability. This study aims to determine the incidence and risk factors for ischemic strokes in a large cohort of Chagas cardiomyopathy patients, with a particular focus on the mechanisms involved in the pathophysiology of stroke in this condition. METHODS: The study enrolled 517 patients with Chagas cardiomyopathy who were referred to our institution from March 2000 to December 2021. All patients underwent systematic cardiological and neurological assessments. The primary outcome was the occurrence of ischemic stroke during the follow-up period, classified based on the SSS-TOAST and CCS criteria. Natural cubic splines functions were applied to examine the potential nonlinear association between continuous variables and stroke risk. RESULTS: The mean age of the cohort was 52 ± 13 years, and 299 (58 %) were men. During a mean follow-up period of 4.8 years (interquartile range-IQR 1.1 to 7.1 years), a total of 72 patients (14.8 %) had an ischemic stroke, being fatal in 10. The overall incidence rate of ischemic stroke was 3.0/100 patient-years (95 % confidence interval 2.4 to 3.8). The stroke subtypes were cardioembolic (n = 41), undetermined (n = 11), and other subtypes (n = 20). The predictors of stroke were age, left atrial volume, left ventricular ejection fraction (LVEF), LV thrombus and prior stroke with thrombus. There was a nonlinear relationship between stroke risk, LVEF, and left atrial volume. A bimodal distribution of stroke occurrences was observed according to the severity of LV dysfunction, with a threshold for LVEF of 45 %. The final model for stroke risk prediction showed good discrimination, with a C statistic of 0.775. CONCLUSIONS: In a contemporary cohort of Chagas disease patients with a broad spectrum of disease severity, stroke incidence remains high despite anticoagulation. Stroke risk shows a nonlinear association with ventricular dysfunction and left atrial size, highlighting a distinct bimodal pattern of stroke occurrence in Chagas disease.

ABSTRACT

The SARS-CoV-2 virus has been the subject of study by several researchers worldwide since 2020; however, there are points to be clarified. This study aimed to analyze the clinical and nutritional aspects of hospitalized cancer and non-cancer pediatric patients and the association with COVID-19 outcomes. This is a cohort study of hospitalized children and adolescents with a laboratory diagnosis of COVID-19. Patients were assessed according to the presence or absence of previous oncological diseases. Sociodemographic, clinical and nutritional data were investigated during the course of the infection. Outcomes included Intensive Care Unit (ICU) admission, longer length of stay (14 days), criticality, and death. Oncological disease was found in 16 (19.3%) patients, most of whom had B-type acute lymphoid leukemia. In Poisson regression, adjusted for age and comorbidity, an association was found between oncological disease and length of stay ≥14 days (RR 4.30; 95% CI 1.46 - 15.6; p = 0.013), COVID-19 criticality (RR 3.82; 95% CI 1.66 - 30.9; p = 0.010) and death (RR 3.42; 95% CI 0.94 - 9.96; p = 0.035). The research revealed that cancer patients had longer hospital stays, were more likely to have the severe form of COVID-19, and had a 3.42 times greater risk of dying.

ABSTRACT

This study explored how heterosexual and lesbian women differ in their implicit sexual responses. Previous research indicates that heterosexual women have physiological and implicit responses to both genders, whereas lesbian women show stronger responses to their preferred gender. This study used two implicit measures: the Implicit Relational Assessment Procedure (IRAP) and the Function Acquisition Speed Test (FAST), both of which were novel in this context. We recruited 33 heterosexual and 25 lesbian women. Both IRAP and FAST were successful in differentiating the two sexual orientations as a group. The results confirmed that heterosexual women exhibit positive responses to both genders, while lesbian women show stronger, category-specific responses to their preferred gender. These findings align with previous research and provide further insight into the nuanced differences in sexual orientation responses among women.

ABSTRACT

Evolutionary body size decrease has profound consequences for the morphology of an organism. In the evolution of the Characidae, the most species-rich family of Neotropical fishes, a prominent trend is the reduction of body size. The most typical effect is the simplification and reduction of morphological features through terminal deletion processes, resulting in the loss of skeletal elements and structures. To provide further information on the matter, we present a detailed description of the skeleton of Hyphessobrycon piabinhas, a poorly known, small representative of the largest genus of Characidae. We further discuss the identity and phylogenetic relationships of H. piabinhas. It belongs to the subfamily Stethaprioninae and exhibits considerable morphological similarity to other congeners from neighboring drainage systems. We identify several morphological simplifications in H. piabinhas and discuss them based on ontogenetic data available for Characiformes. These developmentally truncated elements are also present in many other small representatives of the family and seem to be among the first morphological modifications to occur in the context of body size reduction of Characidae. We argue that structural losses are not strictly correlated with sizes below 26 mm SL, although the most notable simplifications are typically observed in the miniatures.

ABSTRACT

MAIN CONCLUSION: Despite modulating senescence and drought responses, the GmERD15-like subfamily members are differentially induced by multiple stresses and diverge partially in stress signaling functions. The PAM2 motif represents a binding site for poly (A)-binding proteins (PABPs), often associated with RNA metabolism regulation. The PAM2-containing protein ERD15 stands out as a critical regulator of diverse stress responses in plants. Despite the relevance of the PAM2 motif, a comprehensive analysis of the PAM2 superfamily and ERD15-like subfamily in the plant kingdom is lacking. Here, we provide an extensive in silico analysis of the PAM2 superfamily and the ERD15-like subfamily in soybean, using Arabidopsis and rice sequences as prototypes. The Glycine max ERD15-like subfamily members were clustered in pairs, likely originating from DNA-based gene duplication, as the paralogs display high sequence conservation, similar exon/intron genome organization, and are undergoing purifying selection. Complementation analyses of an aterd15 mutant demonstrated that the plant ERD15-like subfamily members are functionally redundant in response to drought, osmotic stress, and dark-induced senescence. Nevertheless, the soybean members displayed differential expression profiles, biochemical activity, and subcellular localization, consistent with functional diversification. The expression profiles of Glyma04G138600 under salicylic acid (SA) and abscisic acid (ABA) treatments differed oppositely from those of the other GmERD15-like genes. Abiotic stress-induced coexpression analysis with soybean PABPs showed that Glyma04G138600 was clustered separately from other GmERD15s. In contrast to the AtERD15 stress-induced nuclear redistribution, Glyma04G138600 and Glyma02G260800 localized to the cytoplasm, while Glyma03G131900 fractionated between the cytoplasm and nucleus under normal and stress conditions. These data collectively indicate that despite modulating senescence and drought responses, the GmERD15-like subfamily members are differentially induced by multiple stresses and may diverge partially in stress signaling functions.

ABSTRACT

This study aimed to evaluate the effect of replacing Tifton 85 hay (TH) with Moringa hay (MH) on the intake, apparent digestibility, ingestive behaviour, rumen parameters, serum attributes, nitrogen balance, water balance, and urinary attributes of sheep. Thus, 5 rams, ½ Dorper + ½ Santa Inês, that were 12 ± 4 months of age with an initial body weight of 32.8 ± 2.6 kg were distributed in metabolic cages in a Latin square design. The experiment lasted 85 days and was divided into five 17-day periods. The animals received rations with increasing replacement (0, 100, 200, 300, or 400 g/kg of dry matter in the total diet) of TH for MH. The forage: concentrate ratio of the diets was 40:60. Replacing TH with MH reduced (P < 0.05) the intake of organic matter, crude protein, neutral detergent fibre (NDFap), and total digestible nutrients by sheep. The apparent digestibility of NDFap and the feeding and rumination efficiencies of NDFap were reduced (P < 0.05) when MH replaced TH in the animals' diet. This replacement did not influence (P > 0.05) serum urea, total protein, creatinine, or aspartate aminotransferase in sheep. Replacing TH with MH decreased water intake and excretion (P < 0.05). In addition, nitrogen excretion via urine, urinary creatinine, and nitrogen absorption decreased (P < 0.05) when TH was replaced with MH. However, there was an increase in the sheep's nitrogen retention and urine pH. We recommend replacing 30% TH with MH in the diet of lambs because it does not compromise nutrient metabolism.

ABSTRACT

Background: Elevated anxiety levels are common in patients on mechanical ventilation (MV) and may challenge recovery. Research suggests music-based interventions may reduce anxiety during MV. However, studies investigating specific music therapy techniques, addressing psychological and physiological well-being in patients on MV, are scarce. Methods: This three-arm randomized clinical pilot study was conducted with MV patients admitted to the intensive care unit (ICU) of Hospital San José in Bogotá, Colombia between March 7, 2022, and July 11, 2022. Patients were divided into three groups: intervention group 1 (IG1), music-assisted relaxation; intervention group 2 (IG2), patient-preferred therapeutic music listening; and control group (CG), standard care. The main outcome measure was the 6-item State-Anxiety Inventory. Secondary outcomes were: pain (measured with a visual analog scale), resilience (measured with the Brief Resilience Scale), agitation/sedation (measured with the Richmond Agitation-Sedation Scale), vital signs (including heart rate, blood pressure, oxygen saturation, and respiratory rate), days of MV, extubation success, and days in the ICU. Additionally, three patients underwent electroencephalography during the interventions. Results: Data from 23 patients were analyzed in this study. The age range of the patients was 24.0-84.0 years, with a median age of 66.0 years (interquartile range: 57.0-74.0). Of the 23 patients, 19 were female (82.6%). No statistically significant differences between the groups were observed for anxiety (P=0.330), pain (P=0.624), resilience (P=0.916), agitation/sedation (P=0.273), length of ICU stay (P=0.785), or vital signs. A statistically significant difference between the groups was found for days of MV (P=0.019). Electroencephalography measurements showed a trend toward delta and theta band power decrease for two patients and a power increase on both beta frequencies (slow and fast) in the frontal areas of the brain for one patient. Conclusions: In this pilot study, music therapy did not significantly affect the anxiety levels in patients on MV. However, the interventions were widely accepted by the staff, patients, and caregivers and were safe, considering the critical medical status of the participants. Further large-scale randomized controlled trials are needed to investigate the potential benefits of music therapeutic interventions in this population.Trial Registration ISRCTN trial registry identifier: ISRCTN16964680.

ABSTRACT

Context The overproduction of reactive oxygen species (ROS) during in vitro culture of ovarian tissues impairs follicular development and survival. Aims To evaluate the effects of punicalagin on the development and survival of primordial follicles, stromal cell and collagen fibres, as well as on the levels of mRNA for nuclear factor erythroid 2-related factor 2 (NRF2 ), superoxide dismutase 1 (SOD1 ), catalase (CAT ), glutathione peroxidase 1 (GPX1 ) and perirredoxin 6 (PRDX6 ), and activity of antioxidant enzymes in cultured bovine ovarian tissues. Methods Bovine ovarian cortical tissues were cultured for 6days in α-MEM+ alone or with 1.0, 10.0, or 100.0µM punicalagin at 38.5°C with 5% CO2 . Follicle morphology and growth, stromal cell density, and collagen fibres were evaluated by classical histology, while the expression of mRNA was evaluated by real-time PCR. The activity of enzymes was analysed by the Bradford method. Key results Punicalagin improved follicle survival and development, reduced mRNA expression for SOD1 and CAT , but did not influence stromal cells or collagen fibres. Punicalagin (10.0µM) increased the levels of thiol and activity of SOD1, CAT , and GPX1 enzymes. Conclusions Punicalagin (10.0µM) promotes follicle survival and development and activates SOD1, CAT , and GPX1 enzymes in bovine ovarian tissues. Implications Punicalagin improves follicle development and survival in cultured ovarian tissues.

ABSTRACT

Because of the exoskeleton, arthropods must have flexible areas to be able to move. Such regions are called arthrodial membranes and are particularly vulnerable to bacteria and fungi. Here, we analyzed the secretion in the glands underneath it in a Neotropical harvester Mischonyx squalidus (Arachnida: Opiliones) and tested whether it has antiseptical properties. Wepuncturedthemembrane,collectedand quantified ina spectrophotometer. We also fractionated and analyzed the samples in reversed-phase high-performance liquid chromatography (RP-HPLC) and then incubated the treated fractions and determined growth inhibition by measuring absorbance. The secretions resulted in 100 fractions, among which two had activity against the Gram-positive bacteria Micrococcus luteus and against the yeast Candida albicans. The low concentrations at which the secretions were active are relevant from a biotechnological point of view. For the organism, the secretions possibly prevent infections, including when they are attacked in these regions by predators that pick that spot to bite.

ABSTRACT

Introduction: COVID-19 leads to severe clinical complications that culminate in respiratory failure and acute respiratory distress syndrome (ARDS). Despite reports of some comorbidities that contribute to the development of COVID-19-mediated ARDS, there is great variation in mortality rates among critical COVID-19 patients in the world. To date, no studies have described the incidence and comorbidities associated with ARDS due to COVID-19 in the northeastern region of Mexico. Aim of the study: To describe patients diagnosed with ARDS due to COVID-19 in the northeastern region of Mexico, as well as its variations in comparison with other regions of the country. Material and Methods: We conducted a prospective and observational study in a tertiary care center in Northeastern Mexico. All patients diagnosed with SARS-CoV-2 infection and requiring management in the intensive care unit were included. We developed a database that was updated daily with the patients' demographic information, pre-existing diseases, disease severity, and clinical variables. Results: The incidence of ARDS secondary to COVID-19 in HRAEV was high in comparison with other reports. Diabetes mellitus was the risk factor most associated with COVID-19-mediated ARDS. Conclusion: Based on our findings and those previously reported in the literature, there are differences that we discuss between northeastern and central Mexico, and analyze other areas evaluated around the world.

ABSTRACT

Water springs are manifestations of groundwater to the surface, forming and ensuring the supply and sustainability of streams, lakes, rivers, and dams. Therefore, its riparian forest is considered an area of permanent preservation, which aims to protect the water, as well as the spring, from consequences of disordered population growth, added to deficient basic sanitation systems, climate change, agricultural activities, inappropriate land uses, unplanned urbanization, and diffuse sources of pollution. In addition to compromising water quality, many of these factors affect the permanence of water upwelling at the source, compromising the formation and continuity of streams, lakes, and rivers. In this context, the objective of the present research was to carry out a bibliographic review on water springs, approaching adjacent themes to the main axis of the study that are fundamental for a deep understanding of their importance for the maintenance of water resources and ensuring biodiversity in the search for the sustainability of life for present and future generations. This research collaborates with the environmental view and shows that the function of a water sources is broader than its concepts can reveal.

ABSTRACT

The objective were to evaluate the effects of supplementation of standardized dry extract of Rosmarinus officinalis (RO) and the application of aesthetic radiofrequency on the oxidative stress markers catalase (CAT), superoxide dismutase (SOD), non-protein thiols (NP-SH), and thiobarbituric acid reactive species (TBARS) and the biochemical markers triglycerides, total cholesterol, high density lipoprotein (HDL) cholesterol, glutamic-oxaloacetic transaminase (TGO/AST), pyruvic-glutamic transaminase (TGP/ALT), gamma glutamyl transpeptidase (gamma-GT), and creatinine. This study included 32 women received the aesthetic therapy to reduce localized fat. They were divided into the control group (n = 8) receiving placebo capsules and the intervention group (n = 24) subdivided into Group A, B, and C, each with eight members receiving supplementation with 100, 500, and 1000 mg/day of standardized dry extract of RO, respectively. The Universal Trial Number (UTN) - U1111-1274-6255. Supplementation with RO (500 mg/day) demonstrated a reduction in oxidative stress (quantified with through a significant increase in NP-SH and a reduction in SOD and CAT enzymes). The radiofrequency aesthetic treatment did not promote an increase in oxidative stress; however, it caused significant changes in total cholesterol, HDL cholesterol, and creatinine. RO is a plant with antioxidant effects and its oral consumption is safe in selected women subjects in hepatic and renal markers.

ABSTRACT

OBJECTIVE: To describe independent factors related to the interaction of FTO rs9939609, TMEM18 rs6548238, leptin, and adiponectin in children/adolescents with asthma, under the influence of obesity. METHODS: The authors performed a cross-sectional study with 57 children/adolescents, ages 8-19 years, at a tertiary hospital, from 2017 to 2018. Participants were classified by nutritional status, performed spirometry with a bronchodilator test and completed an asthma questionnaire, higher scores indicated more asthma symptoms. Two asthma groups were formed: Group 1(G1)-normal-weight; Group 2(G2)-overweight/obese. Serum was collected for adipokines (n = 32) and genetic polymorphisms (n = 53) dosages. RESULTS: Age and body mass index (BMI) correlated directly in normal-weight (p = 0.009) and obese participants (p = 0.004). Girls reported more asthma complaints (p = 0.044). Participants with negative bronchodilator responses presented lower BMI (14.55-17.16) than responders (19.4-26.84) (p = 0.049). Leptin dosages are related directly to BMI (5,34-40 ng/ml in obese × 0,54-42 ng/ml in nonobese) (p = 0.003). Levels were high in girls (4.78-17.55 µg/ml) (p = 0.029) and low in nonobese boys (0.54-6.92 µg/ml) (p = 0.006). In obese, low leptin levels (< 10 ng/ml) were found in small airway dysfunction carriers (p = 0.025); elevated adiponectin (> 5 µg/ml) correlated with FEV1/FVC > 80 % (p = 0.035) and positive bronchodilator tests (8.84-13 µg/ml) (p = 0.039); and FTO A allele correlated with low adiponectin 0-8.84 µg/ml (p = 0.021) and low FEV1/FVC (46 %-88 %) (p = 0.023). CONCLUSION: BMI correlated directly with age and leptin levels. Obese participants presented high serum levels of leptin and FTO A allele correlated with low FEV1/FVC. Larger cohorts are necessary for better elucidation of the role of adipokines and polymorphisms in the pathophysiology of asthma and obesity.

ABSTRACT

BACKGROUND: Individuals who were formerly incarcerated have high tuberculosis incidence, but are generally not considered among the risk groups eligible for tuberculosis prevention. We investigated the potential health impact and cost-effectiveness of Mycobacterium tuberculosis infection screening and tuberculosis preventive treatment (TPT) for individuals who were formerly incarcerated in Brazil. METHODS: Using published evidence for Brazil, we constructed a Markov state transition model estimating tuberculosis-related health outcomes and costs among individuals who were formerly incarcerated, by simulating transitions between health states over time. The analysis compared tuberculosis infection screening and TPT, to no screening, considering a combination of M tuberculosis infection tests and TPT regimens. We quantified health effects as reductions in tuberculosis cases, tuberculosis deaths, and disability-adjusted life-years (DALYs). We assessed costs from a tuberculosis programme perspective. We report intervention cost-effectiveness as the incremental costs per DALY averted, and tested how results changed across subgroups of the target population. FINDINGS: Compared with no intervention, an intervention incorporating tuberculin skin testing and treatment with 3 months of isoniazid and rifapentine would avert 31 (95% uncertainty interval 14-56) lifetime tuberculosis cases and 4·1 (1·4-5·8) lifetime tuberculosis deaths per 1000 individuals, and cost US$242 per DALY averted. All test and regimen combinations were cost-effective compared with no screening. Younger age, longer incarceration, and more recent prison release were each associated with significantly greater health benefits and more favourable cost-effectiveness ratios, although the intervention was cost-effective for all subgroups examined. INTERPRETATION: M tuberculosis infection screening and TPT for individuals who were formerly incarcerated appears cost-effective, and would provide valuable health gains.

ABSTRACT

The Amazonian coastal ecosystems face a significant threat from plastic contamination, posing a major risk to their biodiversity. Here, we provide the first evidence of using plastics in nest building by Yellow-cacique Cacique (Cacicus cela) and Greater Kiskadee (Pitangus sulphuratus). During 2023 and 2024, 15 nests built with ropes and fishing lines were recorded in the Brazilian Amazon Coast, a colony of 12 nests in the State of Amapá and one nest in Pará for C. cela, and one nest for P. sulphuratus was observed in Maranhão during the fieldwork, covering all Brazilian Amazon Coast. These nests were observed on the edge of mangroves, built with solid waste from fishing activities, pointing out how environmental pollution can be incorporated into wildlife this issue. Our records emphasize the effect of plastic pollution on two passerine species associated with mangrove forests and the need for conservation measures and further research.

ABSTRACT

This study aims to investigate the essential oil from leaves of Eugenia pohliana (EOEP) in regard to its chemical composition, antimicrobial and drug-enhancing activity, as well as the reduction of fungal virulence capacity. Chemical characterization using GC-MS showed as major components the sesquiterpenes δ-cadinene, Epi-α-Muurolol, and bicyclogermacrene. The results of antibacterial tests indicated that Staphylococcus aureus was more sensitive to EOEP, that also enhanced the efficacy of gentamicin, erythromycin, and norfloxacin. EOEP exhibited antifungal properties against Candida albicans, in addition to potentiating the effectiveness of fluconazole against Candida tropicalis. It showed anti-virulence effects in all fungal strains. These findings underscore E. pohliana as a potential candidate for the prospection of novel therapeutic agents to treat infectious diseases caused by resistant microbes.
