Mannan and β-(1→3)-glucan are two polysaccharide markers that are characteristic for a number of fungal pathogens, including , which is the most common cause of invasive mycoses in humans. In this study, we examined epitope specificity of two monoclonal antibodies, CM532 and FG70, which recognize certain oligosaccharide fragments of these fungal polysaccharides. Using a panel of biotinylated oligosaccharides as coating antigens, we found that the CM532 antibody obtained by immunization with the pentamannoside β-Man-(1→2)-β-Man-(1→2)-α-Man-(1→2)-α-Man-(1→2)-α-Man KLH conjugate, selectively recognizes the trisaccharide β-Man-(1→2)-α-Man-(1→2)-α-Man epitope.

Background: In vivo T-cell depletion with antithymocyte globulin (ATG), especially at high-doses has been shown to be associated with increased incidence of infections after allogeneic hematopoietic stem cell transplantation (HSCT). However, it remains unclear whether ATG, even at low-doses increases the risk of posttransplant infections in the high-risk HSCT setting.
Patients And Methods: We conducted a single-center retrospective study of viral and fungal infections early after transplantation, using the data from 82 patients with hematological malignancies.

The polysaccharide chitosan possesses broad-spectrum antimicrobial properties and has proven effective in controlling various postharvest diseases in fruits. Nevertheless, the fundamental mechanisms underlying its action remain unclear. In this study, the antifungal effects of chitosan with different molecular weights against Fusarium avenaceum, a pathogen causing root rot in Angelica sinensis, were evaluated.

Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.
Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.
