Biogenic silver nanoparticles in the treatment of experimental pythiosis Bio-AgNP in pythiosis therapy.

Pythiosis is a rapidly progressing disease that can be lethal to affected individuals due to resistance to available therapeutic protocols. The disease affects mammals, with the largest number of reports in horses and humans. The present study investigated the activity of biogenic silver nanoparticles (bioAgNP) in the treatment of experimental pythiosis.

Treatment of experimental pythiosis with essential oils of Origanum vulgare and Mentha piperita singly, in association and in combination with immunotherapy.

This study investigated the in vivo antimicrobial activity of the essential oils of Origanum vulgare and Mentha piperita both singly, associated and in combination with immunotherapy to treat experimental pythiosis. The disease was reproduced in 18 rabbits divided into six groups (n=3): group 1, control; group 2, treated with essential oil of Mentha piperita; group 3, treated with essential oil of Origanum vulgare; group 4, treated with commercial immunotherapic; group 5, treated with a association of oils of M. piperita and O.

Gastric pythiosis in a dog.

Background: Pythiosis is caused by the agent Pythium insidiosum, an aquatic oomycete of the kingdom Stramenopila.

Aims: To describe the symptoms, pathological changes and diagnosis methods of gastric pythiosis in dogs.

Methods: A three-year-old female German shepherd, with access to wetlands, was attended due to vomiting and recurrent diarrhea of 30 days of duration.

In vitro and in vivo susceptibility of two-drug and three-drug combinations of terbinafine, itraconazole, caspofungin, ibuprofen and fluvastatin against Pythium insidiosum.

The present study investigated the in vitro inhibitory activity of terbinafine, itraconazole, caspofungin, fluvastatin and ibuprofen against 15 isolates of Pythium insidiosum in double and triple combinations and determined in vivo correlations using rabbits with experimental pythiosis. The minimal inhibitory concentration (MIC) was determined in accordance with the Clinical and Laboratory Standards Institute M 38-A2 protocol (2008), and the in vitro interactions were evaluated using a checkerboard microdilution method. For the in vivo study, 20 rabbits inoculated with P.
