Clinical and mycological investigations of post-COVID-19 acute invasive fungal sinusitis.

Objectives: An increased incidence of acute invasive fungal sinusitis associated with the recent COVID-19 pandemic has been observed, which is considered a public health concern. This study aims to detect the incidence, risk factors, causative agents, clinical presentations, outcomes, and susceptibility rate of various antifungals.

Methods: In this cross-sectional cohort study, a total of 30 patients showing acute invasive fungal rhinosinusitis following a COVID-19 infection were investigated.

Genetic and antimicrobial resistance profiles of non-O157 Shiga toxin-producing Escherichia coli from different sources in Egypt.

Background: The Shiga toxin-producing Escherichia coli (STEC) represented a great risk to public health. In this study, 60 STEC strains recovered from broiler and duck fecal samples, cow's milk, cattle beef, human urine, and ear discharge were screened for 12 virulence genes, phenotypic and genotypic antimicrobial resistance, and multiple-locus variable-number tandem-repeat analysis (MLVA).

Results: The majority of strains harbored Shiga toxin 1 (stx) and stx, stx and stx, and ehxA genes, while a minority harbored stx subtype and eaeA.
