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)
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)
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 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)
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 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)
OBJECTIVE To develop and optimize polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) targeting 18S rDNA and internal transcribed spacer (ITS) region of fungi for rapid detection and identification of dermatophytes. MATERIALS AND METHODS Two PCR-RFLP methods targeting 18S rDNA and ITS regions of fungi were optimized using(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)
OBJECTIVE To develop a novel RNA based assay to determine the Gram reaction and viability of bacteria in clinical specimens. MATERIALS AND METHODS Reverse transcriptase PCR (RT-PCR) targeting 16SrRNA region was optimized using Staphylococcus aureus ATCC 25923 and Pseudomonas aeruginosa ATCC 27853 by using two novel sets of primers. Sixty clinical(More)
UNLABELLED Scleritis is an ocular inflammatory disorder commonly associated with systemic autoimmune diseases. We report a case of nodular scleritis with an etiological diagnosis of tuberculosis wherein diagnosis was possible only after histopathological examination of the enucleated eye. METHOD OF STUDY A 52 year female patient was referred as a case of(More)
