is the leading bacterial cause of diarrhea worldwide, with increasing levels of antibiotic resistance. The greatest burden is among children aged <5 years in low- and middle-income countries, and efforts are ongoing to develop vaccines against this pathogen. One of the challenges associated with the development of a vaccine against is the need for a multivalent vaccine covering the most prevalent serotypes.

Klebsiella pneumoniae (Kp) poses an escalating threat to public health, particularly given its association with nosocomial infections and its emergence as a leading cause of neonatal sepsis, particularly in low- and middle-income countries (LMICs). Host cell adherence and biofilm formation of Kp is mediated by type 1 and type 3 fimbriae whose major fimbrial subunits are encoded by the fimA and mrkA genes, respectively. In this study, we focus on MrkA subunit, which is a 20 KDa protein whose 3D molecular structure remains elusive.

Introduction: is the etiologic agent of a bacillary dysentery known as shigellosis, which causes millions of infections and thousands of deaths worldwide each year due to 's unique lifestyle within intestinal epithelial cells. Cell adhesion/invasion assays have been extensively used not only to identify targets mediating host-pathogen interaction, but also to evaluate the ability of -specific antibodies to reduce virulence. However, these assays are time-consuming and labor-intensive and fail to assess differences at the single-cell level.

Shigellosis is one of the leading causes of diarrheal disease in low- and middle-income countries, particularly in young children, and is more often associated with antimicrobial resistance. Therefore, a preventive vaccine against shigellosis is an urgent medical need. We have proposed Generalised Modules for Membrane Antigens (GMMA) as an innovative delivery system for O-antigen, and an Alhydrogel formulation (1790GAHB) has been extensively tested in preclinical and clinical studies.

(Kp) is a Gram-negative bacterium, and a leading cause of neonatal sepsis in low- and middle-income countries, often associated with anti-microbial resistance. Two types of polysaccharides are expressed on the Kp cell surface and have been proposed as key antigens for vaccine design: capsular polysaccharides (known as K-antigens, K-Ags) and O-antigens (O-Ags). Historically, Kp has been classified using capsule serotyping and although 186 distinct genotypes have been predicted so far based on sequence analysis, many structures are still unknown.

A Family and Community Health Nursing (FCHN) model was first conceptualized by the WHO approximately 25 years ago in response to the epidemiological transition leading to major changes in the population health needs. To date, no study has comprehensively explored the adherence of current applications of FCHN to the WHO original framework. We carried out a scoping review on PubMed, Scopus and CINAHL with the aim to compare the main features of FCHN models developed at the international level with the WHO's framework.

Shigellosis is a leading cause of diarrheal disease in low-middle-income countries (LMICs). Effective vaccines will help to reduce the disease burden, exacerbated by increasing antibiotic resistance, in the most susceptible population represented by young children. A challenge for a broadly protective vaccine against shigellosis is to cover the most epidemiologically relevant serotypes among >50 Shigella serotypes circulating worldwide.

In clinical scenarios, the use of biomedical sensors, devices and multi-parameter assessments is fundamental to provide a comprehensive portrait of patients' state, in order to adapt and personalize rehabilitation interventions and support clinical decision-making. However, there is a huge gap between the potential of the multidomain techniques available and the limited practical use that is made in the clinical scenario. This paper reviews the current state-of-the-art and provides insights into future directions of multi-domain instrumental approaches in the clinical assessment of patients involved in neuromotor rehabilitation.

Shigellosis causes more than 200,000 deaths worldwide and most of this burden falls on Low- and Middle-Income Countries (LMICs), with a particular incidence in children under 5 years of age. In the last decades, has become even more worrisome because of the onset of antimicrobial-resistant strains (AMR). Indeed, the WHO has listed as one of the priority pathogens for the development of new interventions.

Article Synopsis
  • Shigellosis, a major cause of diarrhea in children from low- and middle-income countries, faces challenges due to antimicrobial resistance and currently lacks widely available vaccines.
  • Researchers are developing a quadrivalent vaccine using Generalized Modules for Membrane Antigens (GMMA), aiming to induce strong immune responses against Shigella's O-antigen and proteins from three prevalent serotypes.
  • The study shows that GMMA can enhance immunogenicity by providing T cell help, and the activation of Toll-like Receptor 4 (but not TLR2) is crucial for this process, improving the overall effectiveness of carbohydrate antigens in vaccines.
