The genus Pythium embraces 200 species. They’re one of one of the most destructive plant pathogens, infecting crops and destroying the seeds, storage organs, roots, as well as other plant tissues [1]. The genus was thought of as correct fungi by Pringsheim in 1858 resulting from traits like eukaryotes with filamentous growth, absence of septa, nutrition by absorption, and reproduction through spores [2]. Nevertheless, because the understanding of evolution has developed, the Pythium species are now becoming classified as protozoan, as they’ve cellulose, beta-glucans, and hydroxyproline in their cell walls [2].

The patient was subsequently diagnosed with sickle cell trait [3]. Because then, 168 ocular pythiosis situations happen to be reported inside the literature until 2021 [5]. PI keratitis has been sparsely reported resulting from varied factors such as lack of information regarding the microscopic and colony morphology of your organisms among the microbiologists, falsely labeling it as an unidentified fungus, absence of growth in the culture, lack of high clinical suspicion amongst the clinicians, delayed diagnosis, and its clinical resemblance to fungus [6]. The frequent systemic and ocular risk factors identified for Pythium infection are thalassemias, sickle cell trait, swimming with make contact with lenses, exposure to farm animals, and swampy locations [7].PMID:24059181 Lately, a few studies from South India reported a larger incidence of PI keratitis in homemakers and IT pros [8, 9]. Early diagnosis and prompt differentiation from fungal keratitis (FK) are imperative for quick initiation of appropriate therapy for Pythium to yield a great prognosis [7]. The direct microscopic examination of smears with Gram staining and KOH mount, around the cursory appear, may resemble fungal filaments. The sensitivity ranges from 79.3 to 96.5 [8]. Nevertheless, the microbiologist’s familiarity with all the typical appearance of Pythium filaments, which seem as broad, ribbon-like filaments with suitable angle branches, would assistance in the early identification of your infection [9].
