Identification and genetic characterization of Saprolegnia parasitica, isolated from farmed and wild fish in Finland

Journal of Fish Diseases, Volume 46, Issue 8, Page 849-860, August 2023., 2023
Abstract Oomycete infections in farmed fish are one of the most significant disease issues in salmonid aquaculture worldwide. In the present study, Saprolegnia spp. in different farmed fish species in Finland were identified, and the molecular epidemiology of especially Saprolegnia parasitica was examined.

Successful management of colonic pythiosis in two dogs in Thailand using antifungal therapy

Veterinary Medicine and Science, Volume 8, Issue 6, Page 2283-2291, November 2022., 2022
Successful management of colonic pythiosis in two dogs in Thailand using antifungal therapy. Abstract Gastrointestinal pythiosis is a severe, progressive and often a fatal disease, which is caused by the aquatic pathogen Pythium insidiosum. Treatment is challenging due to the disease's resistance to antifungal drugs.

Mechanism of action, resistance, synergism, and clinical implications of azithromycin

Journal of Clinical Laboratory Analysis, Volume 36, Issue 6, June 2022., 2022
Azithromycin, sold under the name Zithromax, is classified as a macrolide. It has many benefits due to its immunomodulatory, anti‐inflammatory, and antibacterial effects. Azithromycin mechanism of action including the inhibition of bacterial protein synthesis, inhibition of proinflammatory cytokine production, inhibition of neutrophil infestation, and ...

Mining oomycete proteomes for metalloproteases leads to identification of candidate virulence factors in Phytophthora infestans

Molecular Plant Pathology, Volume 22, Issue 5, Page 551-563, May 2021., 2021
Proteome mining and comparative analyses uncovered a large variety of metalloproteases (MPs) in oomycetes. Functional in planta assays pinpointed 12 MPs as potential pathogenicity factors in Phytophthora infestans. Abstract Pathogens deploy a wide range of pathogenicity factors, including a plethora of proteases, to modify host tissue or manipulate ...

Influence of temperature on in vitro zoosporogenesis of Pythium insidiosum [PDF]

Medical Mycology, 2017
This study verified the influence of different temperatures on P. insidiosum in vitro zoosporogenesis. P. insidiosum isolates (n = 26) were submitted to zoosporogenesis and incubated at 5°C, 15°C, 20°C and 37°C (1st stage). Grass fragments were evaluated under optical microscopy at 4, 8, and 24 hours of incubation.
