BACKGROUND & OBJECTIVE Infective keratitis is rare in the absence of predisposing factors. The pattern of risk factors predisposing to infective keratitis varies with geographical regions and also influences the type of infection that occurs. The present study was aimed to identify the specific risk factors that predispose the infective keratitis (non viral) and to determine the association bet...

Nocardiae are Gram-positive, filamentous, aerobic, relatively slow-growing, and weakly acid-fast bacteria which cause nocardiosis in humans. We describe a 53-year-old patient with chronic bronchitis referred to Al-Zahra Hospital, Isfahan. A bronchial washing sample was taken from the patient. A Nocardia-like microorganism was detected in microscopic evaluation. Based on the phenotypic and 16S r...

Nocardia infection occurs primarily among patients with deficient cell-mediated immunity. The portal of entry in the majority of patients with Nocardia infection is pulmonary origin. Central venous catheter-associated bacteremia caused by Nocardia species is very rare, and the optimal management for these situations was indeterminate. Most patients were cured after discontinuation of central ve...

Nocardia is a gram positive, aerobic branched actinomycete; it is an ubiquitous soil saprophyte. As an infecting agent it has been increasingly identified in humans, especially in immuno-suppressed hosts. Nocardia as a cause of septic arthritis is very unusual. The described genus was Nocardia asteroides in nearly all previously reported cases. We report an unusual case of spontaneous Nocardia ...

Recent studies in the Parkinson's literature have cited a tuberculosis-like germ called Nocardia as being responsible for Parkinson's disease. Kohbata seemingly cemented a relationship between Nocardia and Parkinson's by finding serologic evidence in 20 of 20 Parkinson's patients, acknowledging that blood tests for Nocardia and the mycobacteria such as tuberculosis often cross-react, as they be...

Aspergillus and Fusarium are the most common fungi causing mycotic keratitis. Injury to the eye with vegetable matter, cow tail injury, long-term use of topical steroids are some of the risk factors for mycotic keratitis. There are few case reports of keratitis caused by Bipolaris. The human pathogenic species in the genus are Bipolaris spicifera, Bipolaris hawaiiensis, Bipolaris papendorfii, a...

Keratitis is an inflammation of the cornea (the clear, front part of the eye) and is often caused by bacteria, viruses, amoeba, fungi. There are two types of keratitis infectious ulcerative keratitis (IUK), caused by infectious pathogens and noninfectious ulcerative keratitis (NIUK), which has a clinical presentation similar to that of IUK but no known infectious cause and is a diverse disease ...

Fungal Keratitis In article 2202409, Shaozhen Zhao, Zhongwei Niu, Ruibo Yang, and co-workers report a peptide conjugate nano-assembly (PCNA) that permeates corneal stroma kills the hyphae without irritating ocular cornea. PCNA with nano-assembled structure assembly–disassembly behavior could serve as foundation of new therapy for fungal keratitis.

Nocardia species are aerobic, gram-positive, filamentous, partially acid-fast actinomycetes which are found worldwide in soil and decaying organic plant matter. When they infect human beings, they generally enter through the respiratory tract and then disseminate systemically. Rarely has a primary infection occurred as the result of direct inoculation. Isolation of Nocardia from clinical specim...

Background: To explore the prevalence of lacrimal duct obstruction in patients with infectious keratitis, and the necessity of lacrimal duct dredge in the treatment of human infectious keratitis. Methodology/Principle Findings: The design is prospective, non-control case series. Thirty-one eyes from twenty-eight continuous patients with infectious keratitis were included in this study. The pres...
