Pythium insidiosum keratitis in an Australian child

Clinical & Experimental Ophthalmology, 2009
AbstractA 3‐year‐old girl from the Northern Territory developed suppurative keratitis after swimming in pools. A mycelial organism suspected to be Pythium insidiosum was cultured. Treatment with polyhexamethylene biguanide and voriconazole for 5 days was unsuccessful, and a corneal graft was performed.

Human Infectious Corneal Ulcer Caused by Pythium Insidiosum

Cornea, 1993
Pythium insidiosum is a fungus-like organism known to infect a variety of animals. In humans, the few known cases involving Pythium have included arterial infections and cellulitis. We present what we believe to be the first case of P. insidiosum recovered from a human corneal ulcer. The organism is difficult to isolate, causing delays in diagnosis. It

Pythium insidiosum – An Emerging Mammalian Pathogen

2020
Pythiosis is an aggressive and life-threating infection caused by the oomycete Pythium insidiosum. The disease occurs mainly in tropical and subtropical countries and affects humans and other mammals, including wild and domestic (particularly dogs and equines) animals.

Insights into the pathophysiology of iron metabolism in Pythium insidiosum infections

Veterinary Microbiology, 2013
Pythium insidiosum causes life-threatening disease in mammals. Animals with pythiosis usually develop anemia, and most human patients are reported to have thalassemia and the major consequence of thalassemia, iron overload. Therefore, this study evaluated the iron metabolism in rabbits experimentally infected with P. insidiosum.

Enzymatic variability among Brazilian Pythium insidiosum isolates

Revista Iberoamericana de Micología, 2013
Pythium insidiosum is an oomycete classified in the kingdom Stramenopila. P. insidiosum hyphae are not able to initiate infection without the secretion of hydrolytic enzymes, which are considered an important factor in microbial virulence.To evaluate the extracellular enzymatic activity of 14 Brazilian P. insidiosum isolates and a standard strain (ATCC

Jejunal obstruction caused by a Pythium insidiosum granuloma in a mare

Journal of the American Veterinary Medical Association, 1994
An 8-year-old Missouri Fox Trotter mare was examined because of intermittent, low-grade abdominal pain and weight loss for 3 months. Incomplete jejunal obstruction, caused by a granulomatous mass in the wall of the jejunum, was identified during exploratory celiotomy. Pythium insidiosum was identified as the cause of the granuloma.

Clinical recommendations for the management of Pythium insidiosum keratitis

The Ocular Surface
Pythium insidiosum has emerged as a challenging cause of keratitis in recent decades, due to its unique microbiological and clinical features, often is mistaken for fungal keratitis. Anti-fungal therapies have proven ineffective due to the organism's distinct cellular structure.

Leap forward in the treatment of Pythium insidiosum keratitis

British Journal of Ophthalmology, 2018
BackgroundPythium insidiosum is a parafungus that causes keratitis resembling fungal keratitis. This study compares outcome in a large cohort of patients with P insidiosum keratitis treated with antifungal drugs, to a pilot group treated with antibacterial antibiotics.MethodsBetween January 2014 and December 2016, 114 patients with culture positive P ...

The role of neutrophils against Pythium insidiosum

2023
Pythium insidiosum (P. insidiosum) is an oomycetes fungus-like microorganism causing pythiosis infection in humans. The zoospores (infective stage) of this pathogen contaminate aquatic environments such as moist soil and swampy area, which is a natural habitiat. Humans are infected with P.
