Oomicidal activity of polypyrrole nanoparticles against Pythium insidiosum

Letters in Applied Microbiology, 2022
Abstract This study evaluated in-vitro action of a new molecule, the polypyrrole nanoparticles (Ppy-NP), against Pythium insidiosum isolates using M38-A2/CLSI; the minimal inhibitory (MIC) and minimal oomicidal (MOC) concentrations were also determined. Additionally, changes in the hyphae wall of P. insidiosum CBS 575.85 treated with Ppy-

Loop-mediated Isothermal Amplification (LAMP) for Identification of Pythium insidiosum [PDF]

International Journal of Infectious Diseases, 2020
Pythium insidiosum causes a life-threatening condition called pythiosis. High morbidity and mortality of pythiosis are consequences of delayed diagnosis. We aimed to develop a loop-mediated isothermal amplification (LAMP) assay for the rapid detection of P.

Vitamin D‐Mediated Hypercalcemia in a Dog With Putative Cutaneous Pythiosis

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT A 12‐month‐old dog was diagnosed with cutaneous pythiosis after presenting with a nonhealing metatarsal wound, an inguinal mass, and regional lymphadenopathy. Both cytology of the abnormal lymph nodes and histopathology of the inguinal mass showed granulomatous inflammation. ELISA serology was positive for Pythium insidiosum. The dog developed

Pythium insidiosum: morphological and molecular identification of Brazilian isolates

Pesquisa Veterinária Brasileira, 2012
Pythium insidiosum is an oomycete belonging to the kingdom Stramenipila and it is the etiologic agent of pythiosis. Pythiosis is a life-threatening infectious disease characterized by the development of chronic lesions on cutaneous and subcutaneous ...

Canine Pythiosis - Isolation and Identification ofPythium Insidiosum [PDF]

Journal of Veterinary Diagnostic Investigation, 1989
Pythium insidiosum was isolated from the subcutaneous tissue of a 1-year-old tan crossbreed dog and from the intestinal tract of an 18-month-old Samoyed male. Gomori's methenamine silver stain was superior to hematoxylin and eosin in demonstrating the organism in tissue sections. The agent was identified as P.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Relationship between the Antifungal Susceptibility Profile and the Production of Virulence‐Related Hydrolytic Enzymes in Brazilian Clinical Strains of Candida glabrata

Mediators of Inflammation, Volume 2017, Issue 1, 2017., 2017
Candida glabrata is a facultative intracellular opportunistic fungal pathogen in human infections. Several virulence‐associated attributes are involved in its pathogenesis, host‐pathogen interactions, modulation of host immune defenses, and regulation of antifungal drug resistance.

Hyphal Growth in Human Fungal Pathogens and Its Role in Virulence

International Journal of Microbiology, Volume 2012, Issue 1, 2012., 2012
Most of the fungal species that infect humans can grow in more than one morphological form but only a subset of pathogens produce filamentous hyphae during the infection process. This subset is phylogenetically unrelated and includes the commonly carried yeasts, Candida albicans, C.
