Impact of metabolic syndrome on cardiovascular, inflammatory and hematological parameters in female mice subjected to severe sepsis.

The aim of the study was to evaluate the effect of metabolic syndrome (MetS) on female Swiss mice subjected to severe polymicrobial sepsis induced by cecal ligation and puncture (CLP). MetS was induced in neonatal Swiss mice by subcutaneous injection of monosodium glutamate (MSG) at 4 mg/g body weight from day 1 to day 5 after birth, while animals in the control group (CTL) were treated with equimolar saline solution at the same volume and period. On the 75th day of life, the CLP model was used to induce severe polymicrobial sepsis.

Metabolic syndrome induces benefits in mice experiencing severe sepsis, comparable to the effects of low-dose aspirin pretreatment in septic mice lacking metabolic syndrome.

Background: Sepsis is a complex condition characterized by systemic host inflammation caused by an infection. Experimental and observational studies indicate that obesity, one of the components of metabolic syndrome (MetS), or aspirin (ASA) treatment could be associated with sepsis survival. However, the effects of ASA on septic mice with MetS-induced conditions have not been explored.

Risk factors for colonization with extended-spectrum cephalosporin-resistant and carbapenem-resistant Enterobacterales among hospitalized patients in Guatemala: An Antibiotic Resistance in Communities and Hospitals (ARCH) study.

Objectives: The spread of extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) and carbapenem-resistant Enterobacterales (CRE) has resulted in increased morbidity, mortality, and health care costs worldwide. To identify the factors associated with ESCrE and CRE colonization within hospitals, we enrolled hospitalized patients at a regional hospital located in Guatemala.

Methods: Stool samples were collected from randomly selected patients using a cross-sectional study design (March-September, 2021), and samples were tested for the presence of ESCrE and CRE.

The Therapeutic Potential of Angeli's Salt in Mitigating Acute Infection in Mice.

Chagas disease (CD), caused by , is a neglected tropical disease prevalent in Latin America. Infected patients are treated to eliminate the parasite, reduce the cardiomyopathy risk, and interrupt the disease transmission cycle. The World Health Organization recognizes benznidazole (BZ) and nifurtimox as effective drugs for CD treatment.

Colonization With Antibiotic-Resistant Bacteria in a Hospital and Associated Communities in Guatemala: An Antibiotic Resistance in Communities and Hospitals (ARCH) Study.

Background: We estimated the prevalence of colonization with extended-spectrum cephalosporin-resistant Enterobacterales (ESCrE) and carbapenem-resistant Enterobacterales (CRE) from a hospital and associated communities in western Guatemala.

Methods: Randomly selected infants, children, and adults (<1, 1-17, and ≥18 years, respectively) were enrolled from the hospital (n = 641) during the coronavirus disease 2019 (COVID-19) pandemic, March to September 2021. Community participants were enrolled using a 3-stage cluster design between November 2019 and March 2020 (phase 1, n = 381) and between July 2020 and May 2021 (phase 2, with COVID-19 pandemic restrictions, n = 538).

Beneficial effects of acetylsalicylic acid (aspirin) on the actions of extracellular vesicles shed by Trypanosoma cruzi in macrophages.

Trypomastigote forms of Trypanosoma cruzi, the causative agent of Chagas disease, shed extracellular vesicles (EVs) that promote the susceptibility of host cells to infection. During T. cruzi infection, the immune response of the host is important for controlling parasitism, which is necessary for survival.

Metabolic syndrome improves cardiovascular dysfunction and survival during cecal ligation and puncture-induced mild sepsis in mice.

Aims: Sepsis is a potentially fatal systemic inflammatory response and its underlying pathophysiology is still poorly understood. Studies suggest that obesity, a component of metabolic syndrome (MS), is associated with sepsis survival. Therefore, this study focused on investigating the influence of MS on mortality and cardiovascular dysfunction induced by sublethal cecal ligation and puncture (SL-CLP).

Polymorphism analysis of the apxIA gene of Actinobacillus pleuropneumoniae serovar 5 isolated in swine herds from Brazil.

The bacterium Actinobacillus pleuropneumoniae is the etiological agent of Contagious Porcine Pleuropneumonia, a disease responsible for economic losses in the swine industry worldwide. A. pleuropneumoniae is capable of producing proteinaceous exotoxins responsible for inducing hemorrhagic lesions, one of which is ApxI.

Nematophagous fungi combinations reduce free-living stages of sheep gastrointestinal nematodes in the field.

Gastrointestinal nematodes (GIN) can reduce or limit sheep production. Currently there is a clear deficiency in the action of drugs for the control of these parasites. Nematophagous fungi are natural enemies of GIN.

Mycoplasma hyopneumoniae genetic variability within a swine operation.

The objective of our study was to characterize the Mycoplasma hyopneumoniae genetic diversity within a swine operation comingling weaned pigs. Bronchial swabs and tracheal aspirates were collected from 3 nursery-to-finish farms. During the finishing production stages, samples were obtained from mortalities and from live coughing pigs in rooms where mortality was not observed.

Genotyping of Mycoplasma hyorhinis using multiple-locus variable number tandem repeat analysis.

Mycoplasma hyorhinis (M. hyorhinis) has re-emerged as an important swine pathogen in recent years causing significant economic losses in post weaning pigs. Genetic variability of M.

Genotype distribution of Mycoplasma hyopneumoniae in swine herds from different geographical regions.

Genetic heterogeneity of Mycoplasma hyopneumoniae in pigs has been reported, however there has been limited reproducibility on the molecular methods employed so far. The aim of this study was to modify and standardize a high-resolution multiple locus variable number tandem repeat analysis (MLVA), to investigate the genetic variability of M. hyopneumoniae circulating in the United States of America (USA), Brazil, Mexico and Spain.

ISSR markers as a tool for the assessment of genetic diversity in Passiflora.

Genetic variation among sweet, purple, and yellow passion fruit accessions was assessed using inter-simple sequence repeat (ISSR) markers. Eighteen ISSR primers were used to evaluate 45 accessions. The number of polymorphic bands per primer varied from 4 to 22, with 12.
