Uropathogenic Escherichia coli (UPEC) are one of the main bacteria causing urinary tract infections (UTIs). The rates UPEC with high resistance towards antibiotics and multidrug-resistant have increased dramatically in recent years could difficult treatment. aim study was to determine bacteria, antibiotic profile, virulence traits, genetic background 110 E. isolated from community (79 isolates) hospital-acquired (31 infections. plasmid-mediated quinolone genes presence also investigated. A...
Contamination of surface waters in developing countries is a great concern. Treated and untreated wastewaters have been discharged into rivers streams, leading to possible waterborne infection outbreaks may represent significant dissemination mechanism antibiotic resistance genes. In this study, the water quality San Pedro River, main river pluvial collector Aguascalientes State, Mexico was assessed. Thirty sample locations were tested throughout River. The physicochemical parameters...
Waste stabilization ponds (WSPs) are a cost-efficient method to treat municipal and non-toxic industrial effluents. Numerous studies have shown that WSPs source of greenhouse gas (GHG). However, most reports concerned anaerobic (AP) few addressed GHG emissions from facultative (FP) aerobic/maturation (MPs). In this paper, three WSP in series presented. These were designed as anaerobic, treating agricultural wastewater. CH4 fluxes 0.6 +/- 0.4 g m(-2) d(-1) the MP, 7.0 1.0 (AP), measured. A...
A molecular characterization of the main phytochemicals and antioxidant activity Opuntia robusta (OR) fruit extract was carried out, as well an evaluation its hepatoprotective effect against diclofenac (DF)-induced acute liver injury evaluated. Phenols, flavonoids betalains were quantified, performed by means ABTS•+, DPPH FRAP assays. UPLC-QTOF-MS/MS used to identify biocompounds present in OR out via. In vivo model, groups rats treated prophylactically with extract, betanin N-acteylcysteine...
The leaves of Psidium guajava L. are an agro-industrial by-product with outstanding content polyphenolic compounds; however, there many factors which can affect the phytochemical profile when valuing this type plant material, such as temperatures and extraction times involving in methods applied. In context, study analyzed impact different (Soxhlet, maceration ultrasound-assisted extraction) on (FTIR UPLC-MS) antioxidant activity (ABTS, FRAP Folin–Ciocalteu) guava leaf extracts. A yield...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of Coronavirus disease 2019 (COVID-19), a pandemic declared in 2020. The clinical manifestations this pathology are heterogeneous including fever, cough, dyspnea, anosmia, headache, fatigue, taste dysfunction, among others. Survivors COVID-19 have demonstrated several persistent symptoms derived from its multisystemic physiopathology. These can be chest pain, dry and productive insufficiency, psychoemotional...
In this work, we present a simple, finite-difference method to approximate positive and bounded solutions of parabolic partial differential equation with nonlinear diffusion, which describes the growth dynamics colonies bacteria. A theorem on existence uniqueness model considered is available in standard literature; however, analytical for are difficult calculate exact form. The linear approach used manuscript provides convenient way represent vector form through multiplication new...
Actinobacillus pleuropneumoniae is the aetiological agent of porcine pleuropneumonia and normally transmitted by aerosols direct contact between animals. A. has traditionally been considered an obligate pathogen pigs its presence in environment yet to be investigated. Here, was detected drinking water pig farms Mexico using a PCR specific for RTX toxin gene, apxIV. The farm confirmed indirect immunofluorescence pleuropneumoniae-specific polyclonal antibody fluorescent situ hybridization....
Actinobacillus pleuropneumoniae is the etiologic agent of porcine contagious pleuropneumonia, which causes important worldwide economic losses in swine industry. Several respiratory tract infections are associated with biofilm formation, and A. has ability to form biofilms vitro. Biofilms structured communities bacterial cells enclosed a self-produced polymer matrix that attached an abiotic or biotic surface. Virtually all bacteria can grow as biofilm, multi-species most common microbial...
Staphylococcus aureus and Candida albicans have been co-isolated from biofilm-associated diseases such as denture stomatitis, periodontitis, burn wound infections, well medical devices. However, the polymicrobial biofilm of both microorganisms has not fully characterized.To characterize C. S. in terms microbial density, synergy, composition, structure, stability against antimicrobials chemical agents.Crystal violet assay was used to measure formation. Scanning electron microscopy confocal...
Urinary tract infections (UTIs) affect more than 150 million people, with a cost of over 3.5 billion dollars, each year. Escherichia coli is associated 70-80% UTIs. Uropathogenic E. (UPEC) has virulence factors including adhesins, siderophores, and toxins that damage host cells. Vacuolating autotransporter toxin (Vat) member serine protease proteins Enterobacteriaceae (SPATEs) present in some uropathogenic strains. Vat been identified 20-36% UPEC almost 68% urosepsis isolates. However, the...
Abstract Background We report large biofilm structures that covered almost the entirety of lumen and surface double-J stents in two postrenal transplant patients, with no development urinary tract infection. Biofilm bacteria one patient were integrated by coccus a net structure, whereas overlapping cells bacilli present other patient. To best our knowledge, this is first time high-quality images architecture noncrystalline biofilms have been found inside from long-term stenting renal...
Uropathogenic Escherichia coli (UPEC) strains are among the leading causes of urinary tract infections (UTIs) worldwide. They can colonize and form biofilms that allow bacteria to survive persist, causing relapses life-threatening sequelae. Here, we analyzed biofilm production, antimicrobial susceptibility, virulence factors, phylogenetic groups in 74 E. isolated from diagnosed patients with UTIs describe their microbiological features ascertain relationship capabilities. High levels...
End-stage renal failure of unknown origin (ESRD-UO) is a public health problem in Mexico and many regions the world. The prevalence ESRD-UO Aguascalientes, Mexico, one highest worldwide, particularly adults between 20 40 years age. Our aim was to screen adolescents for chronic kidney disease (CKD) identify risk factors histologically characterize with persistent albuminuria.This cross-sectional, observational comparative study whom serum creatinine albumin:creatinine ratio (ACR) were...
