Prevalence of chronic pelvic pain and associated factors among indigenous women of reproductive age in Ecuador.

BACKGROUND: Chronic pelvic pain is a common disease that affects approximately 4% of women of reproductive age in developed countries. This number is estimated to be higher in developing countries, with a significant negative personal and socioeconomic impact on women. The lack of data on this condition in several countries, particularly those in development and in socially and biologically vulnerable populations such as the indigenous, makes it difficult to guide public policies. OBJECTIVES: To evaluate the prevalence of chronic pelvic pain (dysmenorrhea, dyspareunia, non-cyclical pain) and identify which variables are independently associated with the presence of the condition in indigenous women from Otavalo-Ecuador. DESIGN: A cross-sectional study was carried out including a sample of 2429 women of reproductive age between 14 and 49 years old, obtained from April 2022 to March 2023. A directed questionnaire was used, collected by bilingual interviewers (Kichwa and Spanish) belonging to the community itself; the number of patients was selected by random sampling proportional to the number of women estimated by sample calculation. Data are presented as case prevalence, odds ratio, and 95% confidence interval, with p < 0.05. RESULTS: The prevalence of primary dysmenorrhea, non-cyclic pelvic pain, and dyspareunia was, respectively, 26.6%, 8.9%, and 3.9%.all forms of chronic pain were independently associated with each other. Additionally, dysmenorrhoea was independently associated with hypertension, intestinal symptoms, miscegenation, long cycles, previous pregnancy, use of contraceptives and pear body shape. Pain in other sites, late menarche, exercise, and pear body shape were associated with non-cyclic pelvic pain. And, urinary symptoms, previous pregnancy loss, miscegenation, and pear body shape were associated with dyspareunia. CONCLUSION: The prevalence of primary dysmenorrhea and non-cyclical chronic pelvic pain was notably high, in contrast with the frequency of reported dyspareunia. Briefly, our results suggest an association between dysmenorrhoea and conditions related to inflammatory and/or systemic metabolic disorders, including a potential causal relationship with other manifestations of pelvic pain, and between non-cyclical pelvic pain and signs/symptoms suggesting central sensitization. The report of dyspareunia may be influenced by local cultural values and beliefs.

Francisella salimarina infection in farmed cobia (Rachycentron canadum) and dusky grouper (Epinephelus marginatus) in Brazil: A case report.

This study aimed to identify and characterize isolates of Francisella salimarina associated with an outbreak on a marine fish farm in Brazil and to analyse their genetic variability and antimicrobial susceptibility. In 2021, diseased cobias (Rachycentron canadum, n = 10) and dusky groupers (Epinephelus marginatus, n = 10) were sampled and subjected to bacteriological and pathological examinations. The isolates obtained were morphologically and biochemically characterized and identified by matrix-assisted laser desorption/ionization-time of flight (MALDI-ToF) and 16S rRNA gene sequencing. The genetic diversity of these isolates was analysed using repetitive extragenic palindromic-polymerase chain reaction (REP-PCR). Antimicrobial susceptibility was assessed using the disk diffusion technique. Macroscopically, the fish presented skin ulcerations, ocular lesions, hepatomegaly and splenomegaly. A pleomorphic, gram-negative, catalase- and oxidase-positive bacterium was isolated from seven cobias and two groupers. The 16S rRNA gene sequences showed >99% coverage and identity with other deposited sequences of F. salimarina. The results of the biochemical analysis corresponded to these bacterial species. Histologically, granulomas were observed in the spleen, liver and heart of the cobias (n = 6), and necrotizing and fibrinous dermatitis and myositis were identified in some groupers (n = 2). The isolates exhibited the same banding pattern when REP-PCR was performed, indicating that they were clonally related. Finally, the antibiogram test, no inhibition halo was observed for amoxicillin and trimethoprim-sulfamethoxazole. To our knowledge, this is the first report of F. salimarina infection in cobias and dusky groupers.

Nickel(II)-Catalyzed Formal [3+2] Cycloadditions between Indoles and Donor-Acceptor Cyclopropanes.

This article describes the development of a nickel-catalyzed regio- and diastereoselective formal [3+2] cycloaddition between N-substituted indoles and donor-acceptor cyclopropanes to synthesize cyclopenta[b]indoles. Optimized reaction conditions provide the desired nitrogen-containing cycloadducts in up to 93% yield and dr 8.6:1 with complete regioselectivity. The substrate scope showed high tolerance to various substituted indoles and cyclopropanes, resulting in the synthesis of six new cyclopenta[b]indoles and the isolation of five derivatives previously reported in the literature. In addition, a mechanistic proposal for the reaction was studied through online reaction monitoring by ESI-MS, allowing for the identification of the reactive intermediates in the Ni(II) catalyzed process. X-ray crystallography confirmed the structure and relative endo stereochemistry of the products. This method enables the fast and efficient construction of fused indolines from readily accessible starting materials.

Delayed diagnosis and increased mortality risk: Assessing the effects of the COVID-19 pandemic on breast cancer recurrence.

OBJECTIVES: The COVID-19 pandemic has had a significant global impact since its declaration in March 2020. The COVID-19 pandemic has disproportionately impacted cancer patients, particularly those with breast cancer. This study aims to analyze the effects of the pandemic on women diagnosed with breast cancer recurrence. METHODS: A cohort study was conducted at a tertiary public hospital in São Paulo State, Brazil. Data were collected from electronic records. Patients diagnosed with breast cancer and experiencing recurrence between January 2011 and March 2022 were included. Survival analysis was performed using the Kaplan-Meier estimator and Cox regression. RESULTS: The study included 187 patients, 45 in the pandemic group (recurrence after March 23, 2020) and 142 in the pre-pandemic group. Distant recurrences were more frequent in both groups (pre-pandemic: 62.7 %, pandemic: 75.5 %). Compared to the pre-pandemic group (1.8 years), the pandemic group experienced a longer mean time to recurrence detection (2.9 years) and significantly decreased median survival (9 months vs. 22 months). The Cox regression analysis confirmed an increased risk of death for women diagnosed with breast cancer recurrence during the pandemic period (HR = 1.92, 95 % CI 1.19‒3.12). CONCLUSION: The present study is among the first to investigate the pandemic's specific effects on breast cancer recurrence, revealing concerning delays in detection and a decrease in survival rates. Prompt diagnosis, timely treatment initiation, and comprehensive support are crucial during public health crises. These findings urge healthcare systems to prioritize tailored care for breast cancer patients during pandemics.

Proteomic analysis of exosomes secreted during the epithelial-mesenchymal transition and potential biomarkers of mesenchymal high-grade serous ovarian carcinoma.

BACKGROUND: The epithelial-mesenchymal transition (EMT) promotes cell signaling and morphology alterations, contributing to cancer progression. Exosomes, extracellular vesicles containing proteins involved in cell-cell communication, have emerged as a potential source of biomarkers for several diseases. METHODS: Our aim was to assess the proteome content of exosomes secreted after EMT-induction to identify potential biomarkers for ovarian cancer classification. EMT was induced in the ovarian cancer cell line CAOV3 by treating it with EGF (10 ng/mL) for 96 h following 24 h of serum deprivation. Subsequently, exosomes were isolated from the supernatant using selective centrifugation after decellularization, and their characteristics were determined. The proteins present in the exosomes were extracted, identified, and quantified using Label-Free-Quantification (LFQ) via Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). To identify potential biomarkers, the obtained proteomic data was integrated with the TGGA database for mRNA expression using principal component analysis and a conditional inference tree. RESULTS: The exosomes derived from CAOV3 cells exhibited similar diameter and morphology, measuring approximately 150 nm, regardless of whether they were subjected to EMT stimulation or not. The proteomic analysis of proteins from CAOV3-derived exosomes revealed significant differential regulation of 157 proteins, with 100 showing upregulation and 57 downregulation upon EMT induction. Further comparison of the upregulated proteins with the TCGA transcriptomic data identified PLAU, LAMB1, COL6A1, and TGFB1 as potential biomarkers of the mesenchymal HGSOC subtype. CONCLUSIONS: The induction of EMT, the isolation of exosomes, and the subsequent proteomic analysis highlight potential biomarkers for an aggressive ovarian cancer subtype. Further investigation into the role of these proteins is warranted to enhance our understanding of ovarian cancer outcomes.

Edwardsiella tarda in Tambaqui (Colossoma macropomum): A Pathogenicity, Antimicrobial Susceptibility, and Genetic Analysis of Brazilian Isolates.

Edwardsiella tarda is a crucial pathogenic bacterium in tropical aquaculture. This bacterium was recently isolated from tambaqui (Colossoma macropomum), a commercially important fish species in Brazil. This study assessed the antimicrobial susceptibility, pathogenicity, and genetic diversity of the tambaqui-derived E. tarda isolates. Fourteen bacterial isolates isolated from tambaqui were identified as E. tarda by using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry and dnaJ gene sequencing. Antimicrobial susceptibility tests were conducted against seven drugs using the disc diffusion assay. The pathogenicity test conducted by intraperitoneal injection of 2.4 × 107 colony-forming units (CFU) fish-1 of E. tarda (ED38-17) into tambaqui juveniles eventually revealed that neither clinical signs nor death were present. However, splenomegaly and whitish areas in the spleen and kidneys were observed. The histological investigation also revealed granulomatous splenitis, nephritis, and hepatitis occurring internally. Repetitive extragenic palindromic-PCR fingerprinting separated the 14 isolates into three genetic groups. The antibiogram revealed that all E. tarda isolates were wild-type (WT) to florfenicol (FLO), norfloxacin (NOR), neomycin (NEO), erythromycin (ERY), and oxytetracycline (OXY); however, some were non-wild-type to sulfamethoxazole/trimethoprim (7.1%) and amoxicillin (21.4%). Therefore, through experimental infection, E. tarda ED38-17 could induce pathogenic effects in C. macropomum. Additionally, three distinct genetic types were found, and the E. tarda isolates were WT to FLO, NOR, NEO, ERY, and OXY. These findings raise awareness of a bacteria causing unseen lesions, a pathogen that will potentially impact tambaqui aquaculture in the future.

Altered Differential Expression of Genes and microRNAs Related to Adhesion and Apoptosis Pathways in Patients with Different Phenotypes of Endometriosis.

We aim to investigate the expression of genes (MAPK1 and CAPN2) and microRNAs (miR-30a-5p, miR-7-5p, miR-143-3p, and miR-93-5p) involved in adhesion and apoptosis pathways in superficial peritoneal endometriosis (SE), deep infiltrating endometriosis (DE), and ovarian endometrioma (OE), and to evaluate whether these lesions share the same pathophysiological mechanisms. We used samples of SE (n = 10), DE (n = 10), and OE (n = 10), and endometrial biopsies of these respective patients affected with endometriosis under treatment at a tertiary University Hospital. Endometrial biopsies collected in the tubal ligation procedure from women without endometriosis comprised the control group (n = 10). Quantitative real-time polymerase chain reaction was performed. The expression of MAPK1 (p < 0.0001), miR-93-5p (p = 0.0168), and miR-7-5p (p = 0.0006) was significantly lower in the SE group than in the DE and OE groups. The expression of miR-30a (p = 0.0018) and miR-93 (p = 0.0052) was significantly upregulated in the eutopic endometrium of women with endometriosis compared to the controls. MiR-143 (p = 0.0225) expression also showed a statistical difference between the eutopic endometrium of women with endometriosis and the control group. In summary, SE showed lower pro-survival gene expression and miRNAs involved in this pathway, indicating that this phenotype has a different pathophysiological mechanism compared to DE and OE.

A propensity score-matched retrospective cohort study of hysterectomies for benign disease during the COVID-19 pandemic

SUMMARY OBJECTIVE: This study aimed to evaluate how the pandemic might have affected the number of elective and urgent hysterectomies for benign gynecological pathologies in a single-care tertiary center in the State of São Paulo, Brazil, and to identify if there were any changes in the need for blood transfusions. METHODS: This is a single-center retrospective cohort study. It involved all non-puerperal and non-oncological hysterectomies from October 2018 to July 2021. Patients were divided into two groups, namely, the pandemic group (46 patients) and the control group (92 patients). Data were collected by reviewing the physical and electronic patient records. We carried out the statistical analysis using the RStudio software. RESULTS: The number of planned hysterectomies was 82 in the pre-pandemic group and 23 in the analysis group, representing a 71.9% decrease. When considering only urgent surgeries, 10 of them happened in the pre-pandemic group, while 23 occurred in the pandemic group, representing an increase of 130%. CONCLUSION: Elective hysterectomies may improve the quality of life of women, reducing abnormal bleeding and pelvic pain. Treatment delay can worsen patients' physiological and biological conditions, such as lower labor production, humor, and social aspects, increasing costs to the healthcare system.

Experiences of Women With Breast Cancer Using Telehealth: A Qualitative Systematic Review.

Breast cancer is the most prevalent malignant neoplasm among women. Its treatment comprises different strategies. Telehealth can ensure continuity of care in distant locations. This study aimed to synthesize qualitative evidence of women's experiences with telehealth during the treatment and follow-up of breast cancer. We performed a qualitative systematic review and meta-synthesis. The databases included in the search were: Pubmed, EMBASE, CINAHAL, and Web of Science. The search combined the terms: breast cancer, telemedicine, telehealth, and qualitative study. The studies included were: qualitative design and mixed methods studies with qualitative components. The COREQ Checklist assisted in assessing the quality of included studies and an adaptation of thematic analysis for the qualitative meta-synthesis. We included twelve articles in the review. In the meta-synthesis, 3 themes emerged. (1) Structure: simple design and space to obtain information but in need of adjustments. (2) Usability: about the benefits and limitations of telehealth. (3) Interaction with health professionals. Telehealth is an accepted strategy for the clinical care of women with breast cancer. Patients identified the need for improvements in structure, usability, and interaction. PROTOCOL REGISTRATION: PROSPERO registration number CRD42021228326, registered 06/02/2021.

Experiences of women with advanced cervical cancer before starting the treatment: Systematic review of qualitative studies.

BACKGROUND: Advanced stage and high mortality are characteristics of cervical cancer in developing countries. Comprehension of the diagnosis itinerary is one of the main strategies to control the disease impact. OBJECTIVES: To identify reasons for the delay in diagnosing symptomatic cervical cancer according to the patient's perspectives reported in qualitative studies. We searched four databases (PubMed, Embase, CINAHL, and Web of Science). SELECTION CRITERIA: We included qualitative studies of women with advanced cervical cancer that explored their experiences before treatment. We excluded unoriginal, non-qualitative, and duplicated studies. DATA COLLECTION AND ANALYSIS: We selected 39 articles for a full-text reading and included 15 in the present review. We chose the Consolidated Criteria for Reporting Qualitative Research (COREQ) for quality assessment and The Model of Pathways to Treatment to guide the codifying process. MAIN RESULTS: Four main themes emerged from the synthesis: (1) Health-seeking motivators; (2) Obstacles to seeking medical care; (3) Diagnosis delay; and (4) Coping with the disease. These themes were derived from patients' personal knowledge and beliefs, social relationships, socioeconomic status, and healthcare system characteristics. CONCLUSIONS: Individual behavior, social factors, and healthcare organization contribute to the delay in diagnosing advanced cervical cancer.

Occurrence of depression and assessment of functional capacity in patients with vascular diseases admitted to a Vascular Surgery Service.

Background: Vascular diseases are associated with significant sequelae and clinical repercussions for the lives of affected patients, which are more serious among the elderly. The consequences of vascular disease, such as limb loss, chronic pain, prolonged hospitalization, and polypharmacy, reduce these patients' autonomy and independence, influencing their wellbeing and quality of life. Objectives: To determine the prevalence of depression and assess functional capacity in patients with vascular diseases admitted to a Vascular Surgery Service. Methods: This is a descriptive, cross-sectional study, carried out at the Vascular Surgery Service of a tertiary hospital with a non-random sample of patients selected consecutively. The geriatric depression scale short form (GDS-15) was used to assess depression and the Katz scale was used for functional assessment. Results: The prevalence of depression in these patients was 60.6%. Associations were observed between depression and consultation with a family doctor in the last 12 months, alcoholism, claudication, diabetes, and individuals who had had an amputation. Individuals' Katz index functional capacity scores were significantly associated with sociodemographic variables, conditions related to vascular disease, and hospitalization. Conclusions: There was a high prevalence of depression in patients with vascular diseases admitted to a vascular surgery service and important reductions in functional capacity in some groups, such as individuals with low educational levels, those who had chronic pain in the lower limbs, patients with diabetes, and those who had had an amputation.

Ocorrência de depressão e avaliação da capacidade funcional em pacientes com doenças vasculares internados em um serviço de cirurgia vascular / Occurrence of depression and assessment of functional capacity in patients with vascular diseases admitted to a Vascular Surgery Service

Resumo Contexto As doenças vasculares estão associadas a importantes sequelas e repercussões clínicas nas vidas dos pacientes acometidos e, em maior relevância, entre os idosos. Consequências da doença vascular como a perda de um membro, dor crônica, internamentos prolongados e a polifarmácia geram, nesses pacientes, perda de autonomia e um grau de dependência, que vão influenciar o bem-estar e a qualidade de vida. Objetivos Determinar a ocorrência de depressão e avaliar a capacidade funcional em pacientes com doenças vasculares internados em um serviço de cirurgia vascular. Métodos Trata-se de um estudo observacional, transversal, prospectivo, realizado no serviço de cirurgia vascular de um hospital terciário, com uma amostra não aleatória selecionada de forma consecutiva. Para avaliar a depressão, foi utilizada a escala de depressão geriátrica resumida e, para a avaliação funcional do indivíduo, foi utilizada a escala de Katz. Resultados A prevalência de depressão nesses pacientes foi de 60,6%. Foi observada associação entre depressão e: consulta com médico do Programa de Estratégia de Saúde da Família nos últimos 12 meses, etilismo, claudicação, diabetes e indivíduos que sofreram amputação. Já em relação à capacidade funcional do indivíduo avaliado através do índice de Katz, ocorreram associações significativas entre variáveis sociodemográficas, condições relacionadas a doença vascular e internamento. Conclusões Existem uma alta prevalência de depressão em pacientes com doenças vasculares internados em um serviço de cirurgia vascular e uma redução importante da capacidade funcional em alguns grupos, como os indivíduos de baixa escolaridade, os que sentiam dor crônica nos membros inferiores, os diabéticos e aqueles que sofreram amputação.

Fatores de risco relacionados à ocorrência da síndrome de burnout em profissionais de saúde que atuam em maternidades públicas durante a pandemia do Coronavírus / Factors related to the occurrence of burnout syndrome in healthcare professionals working in public maternities during the Coronavirus pandemic

Introdução: os desafios da atual pandemia impuseram aos profissionais de saúde a adequação do processo de trabalho, inclusive nas maternidades, que muitas vezes estava em contradição direta com as evidências de humanização da assistência. Isso pode resultar em níveis crescentes de danos ocupacionais. Objetivo: analisar os fatores associados à Síndrome de Burnout (SB) entre profissionais de saúde que atuam na assistência às gestantes, puérperas e recém-nascidos nas maternidades públicas de Aracaju durante a pandemia do coronavírus. Metodologia: trata-se de um estudo descritivo com abordagem quantitativa, realizado com profissionais de saúde que atuavam na assistência materno-infantil nas maternidades. Resultados: A amostra foi realizada por conveniência e contou com a participação de 218 profissionais, os achados revelaram que 98,2% dos profissionais apresentaram sintomatologia positiva ao menos em uma das três dimensões avaliadas, que sugeriram o diagnóstico da SB. Conclusão: a pandemia trouxe forte impacto à saúde emocional às equipes das maternidades estudadas o que resultou em uma alta ocorrência da SB. Com base na presença dos fatores que predispuseram ao surgimento da síndrome pode ser sugerido uma implementação de ações que busquem cuidar do ambiente de trabalho desses profissionais.

Introduction: the challenges of the current pandemic imposed on health professionals the adequacy of the work process, including in maternity hospitals, which was often in direct contradiction with the evidence of humanization of care. This can result in increasing levels of occupational damage. Objective: to analyze the factors associated with burnout syndrome (BS) among health professionals who work in the care of pregnant women, postpartum women and newborns in public maternity hospitals in Aracaju during the coronavirus pandemic. Methodology: this is a descriptive study with a quantitative approach, carried out with health professionals who worked in maternal and child care in maternity hospitals. Results: the sample was carried out for convenience and had the participation of 218 professionals, the findings revealed that 98.2% of professionals had positive symptoms in at least one of the three dimensions evaluated, which suggested the diagnosis of BS. Conclusion: the pandemic had a strong impact on the emotional health of the teams of the maternity hospitals studied, which resulted in a high occurrence of BS. Based on the presence of factors that predisposed to the emergence of the syndrome, an implementation of actions that seek to take care of the work environment of these professionals can be suggested.

Impact of ICU bed availability on ovarian cancer surgical hospitalization rates during the first wave of the coronavirus disease 2019 pandemic.

OBJECTIVES: The coronavirus disease 2019 pandemic, which began in 2020, disrupted healthcare services. Reports of changes in surgical activities coincide with the outbreak period. We aimed to identify if changes could be determined in hospitalization rates of ovarian cancer patients from 2016 to 2020, comparing pre-pandemic and pandemic levels. METHODS: Aggregated data were obtained from the State of São Paulo Secretary of Health regarding ovarian cancer clinical and surgical hospitalization, both Coronavirus disease-specific ICU and infirmary bed occupation rates, average social distancing rates, coronavirus disease 2019 incidence, mortality, and lethality rates. We performed the joinpoint analysis to verify if there were changes regarding hospitalization rates during this period. We also calculated hospitalization rate ratios and tested if they were correlated with pandemic-related variables. RESULTS: Hospitalization rates in the state fell, coinciding with the pandemic. Surgical hospitalization rate ratios were inversely correlated with Coronavirus disease-specific ICU bed occupation rates during the third trimester of 2020, with a Pearson's correlation coefficient of -0.50 (95%CI -0.78 to -0.05, p=0.03). CONCLUSION: These results demonstrate the impact of the coronavirus disease 2019 pandemic on the treatment of conditions that compete for the same healthcare resources.

10-year opportunistic mammographic screening scenario in Brazil and its impact on breast cancer early detection: a nationwide population-based study.

Background: Mammographic screening has been used to reduce breast cancer mortality worldwide and remains the main modality for the early detection of this disease. Women from low- and middle-income countries still lack access to periodic mammograms and efficient health care. This cross-sectional study aimed to explore opportunistic mammographic coverage in Brazil, while considering the privately insured population and its association with early breast cancer (EBC) detection. Methods: Data on population, gross domestic product (GDP), number of mammograms performed under the Sistema Único de Saúde (SUS) public health system or private system, and women diagnosed with early-stage breast cancer from 2010 to 2019 were retrieved from publicly available databases. Results: A total of 39 555 636 mammograms with an average of 3 955 564 ± 395 704 mammograms were obtained per year from 2010 to 2019 in Brazil. Most examinations (58.6%) were performed in the target population (50-69 years old), while 32% were performed in women aged 40-49, and 9.4% were performed in women <40 years or >70 years of age. The 10-year mammogram coverage was 30.6% in the target population and 24.8% in the population aged 40-49 years, with significant variation across states and municipalities. The overall EBC detection rates in Brazil were 30.6% in populations aged 50-70 and 24.8% in those aged 40-50 years. We observed a positive correlation between coverage and EBC detection rate (r = 0.68; P = 0.0001 (50-70 years) and r = 0.75; P < 0.0001 (40-50 years)). According to the GDP, the municipalities with higher GDP per capita had higher mammogram coverage (P < 0.0001). Conclusions: The coverage of mammographic screening for women under the SUS is far below the international guidelines. Additionally, a significant number of mammograms have been performed in non-target populations. This scenario reflects the problematic screening programs in developing countries and reflects low rates of EBC diagnosis. As Brazil is a continental country with heterogeneous socioeconomic indicators, we observed significant variations in the number of mammograms performed by age groups when separated by states and municipalities. Even when considering supplemental health system coverage, municipalities with higher GDP per capita were associated with higher mammogram coverage.

Comparative polyphasic characterization of Weissella strains isolated from beaked whale and rainbow trout (Oncorhynchus mykiss): confirmation of Weissella ceti sp. nov. and description of the novel Weissella tructae sp. nov. isolated from farmed rainbow trout.

The weissellosis agent bacterium (WS08T = CBMAI 2730) was isolated from diseased rainbow trout (Oncorhynchus mykiss) in Brazil. The whole genome sequence of this strain was compared with the Mexican W-1 strain, also isolated from diseased rainbow trout, and with the Weissella ceti type strain CECT 7719 T (= 1119-1A-09 T = CCUG 59653 T), recovered from the beaked whale. Digital DNA-DNA hybridization pairwise analyses scored 98.7% between the Mexican W-1 and Brazilian WS08T but just 24.4% for both fish isolates compared to the W. ceti type strain CECT 7719 T. The 16S rRNA gene sequence comparisons with isolates of W. ceti, available at GenBank, were conducted. All rainbow trout-pathogenic isolates grouped close (97% bootstrap confirmation), but when this group was compared to the W. ceti type strain CECT 7719 T the similarity varied from 78.9 to 79.1%. Phenotypic assays were also conducted, and the W. ceti type strain diverged from WS08T and W-1 in the hydrolysis of aesculin, D-mannose, and potassium gluconate and in the hydrolysis of hippurate. Moreover, WS08T and W-1 showed weak growth at 5 °C whereas no growth was observed for W. ceti CECT 7719 T. The major fatty acids (> 10% total fatty acids) presented by WS08T and W-1 were summed feature 8 (C18:1 ω7c/C18:1 ω6c), summed feature 3 (C16:1 ω6c/C16:1ω7c), and C16:0. The results of phylogenetic and phenotypic analyses clearly differentiated the W. ceti CECT 7719 T type strain from the assessed pathogenic strains obtained from rainbow trout. Therefore, Weissella strains isolated from rainbow trout, here represented by strain WS08T (= CBMAI 2730), should be known as members of a novel species for which the name Weissella tructae sp. nov. is proposed.
