PURPOSE To apply Polymerase Chain Reaction (PCR)-based DNA sequencing targeting Internal Transcribed Spacer (ITS) region for identification of non-sporulating molds (NSM) to species level which formed 12% of ocular isolates of fungi in a tertiary eye hospital in South India. MATERIALS AND METHODS Fifty ocular filamentous fungal NSM isolates recovered from(More)
Multidrug-resistant Pseudomonas aeruginosa strains, which are notable nosocomial pathogens, have greatly increased the mortality rate of septicemic patients due to treatment failure. Here, we report the draft genome sequence of P. aeruginosa strain VRFPA02, a human bloodstream isolate that has phenotypically proven to be resistant to a broad spectrum of(More)
PURPOSE To standardize in-vitro antifungal susceptibility testing by agar dilution method to find out the minimum inhibitory concentration (MIC) of amphotericin B, fluconazole and ketoconazole on ocular fungal isolates. METHODS A total of 180 ocular fungal isolates (130 filamentous fungi and 50 yeasts) were included. The antifungal drugs such as(More)
Endogenous intraocular infection of fungal etiology is extremely rare in an immunocompetent individual. Usually, an antecedent history of trauma, surgery, intravenous drug abuse or an immunocompromized state can be elicited. Scedosporium apiospermum is a known cause of keratomycosis after traumatic implantation and can cause fatal disseminated infection in(More)
PURPOSE To develop RNA based assay - reverse transcriptase polymerase chain reaction (RT-PCR) to detect viable bacteria in intraocular specimens obtained from patients with infectious endophthalmitis. MATERIALS AND METHODS Thirty-five intraocular specimens (19 vitreous fluid and 16 aqueous humor) collected from patients with typical infectious(More)
BACKGROUND & OBJECTIVES Eales' disease is an idiopathic disease resulting in retinal neovascularization, recurrent haemorrhages, with or without retinal detachment predominantly affecting healthy young males (97.6%) in the Indian subcontinent. Inspite of several studies, the aetiology of Eales' disease is not clear. The isolation of Mycobacterium fortuitum(More)
BACKGROUND Uniplex polymerase chain reaction (PCR) for detection of bacterial and panfungal genome has been applied onto a large number of intraocular fluids facilitating management of infective endophthalmitis. AIM To develop and apply a novel, rapid multiplex polymerase chain reaction (mPCR) to detect the presence of eubacterial, Propionibacterium acnes(More)
PURPOSE To analyse the genetic similarity among ocular isolates of Aspergillus flavus by Polymerase chain reaction based Restriction Fragment Length Polymorphism (PCR-RFLP) and DNA sequencing. MATERIALS AND METHODS Seven ocular isolates of A. flavus from 5 patients (3 from paient 1, and four isolates from patients no. 2, 3, 4, and 5 respectively)(More)
Typing of herpes simplex virus (HSV) into its serotypes plays a major role in epidemiology and management of reactivation. To develop and evaluate a polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) was employed using Hae III and Taq I against neutralization test, allele-specific PCR and DNA sequencing for the detection(More)
BACKGROUND The incidence of fungal endophthalmitis has dramatically increased in recent years and rapid detection of fungi using nucleic acid-based amplification techniques is helpful in management. AIM To evaluate semi-nested polymerase chain reaction (PCR) targeting internal transcribed spacer (ITS) region for detection of panfungal genome in ocular(More)
