First description of plasmid mediated quinolone resistance genes in salmonella isolates from Saudi hospitals.

Objectives: To detect resistance genes to fluoroquinolones and β-lactams in Salmonella strains from a Saudi hospital.

Methods: From October 2015 to December 2016, a total of 149 Salmonella strains were collected from stool specimens from patients admitted to King Fahad Hospital of the University, AlKhobar, Saudi Arabia using CHROMagar Salmonella. The organism identification and antimicrobial susceptibility testing were performed using Vitek 2 system.

Expression of cytomegalovirus in glioblastoma multiforme: Myth or reality?

A role for human cytomegalovirus (HCMV) in the pathogenesis of glioblastoma multiforme (GBM) was proposed more than a decade ago and has since generated a considerable debate as a possible therapeutic target. We investigate the presence of HCMV in the specimens of patients with GBM treated in our centre. This is a retrospective cohort study to investigate the presence of HCMV by routine immunohistochemical stains and polymerase chain reaction (PCR)-based molecular analysis on formalin-fixed-paraffin-embedded tissue of all patients with GBM treated in our hospital in 2009-2013 (5 years).

Strongyloides stercoralis infection in kidney transplant recipients.

Strongyloides stercoralis is an uncommon infection in Saudi Arabia. It can establish latency and cause an autoinfection in humans that lasts for years. The infection can get reactivated during immunosuppression and can result in a life-threatening Strongyloides hyperinfection syndrome.

Salmonella bacilli negative image recognized on Diff-Quik stain from pleural fluid cytology.

Understanding the significance of cytopathological tests in evaluating various infectious processes have become very essential nowadays, as it is a safe, fast, and cost-effective procedure. We present a case of a 52-year-old male with Salmonella empyema where the causative organisms were initially identified on cytology, and subsequently confirmed by microbiological culture. Diff-Quik stained smears showed many colorless, slender, fat short bacilli, which were visualized against the blue-gray background of the smear.
