Purpureocillium lilacinum and Trichoderma virens for biological control of trichostrongylid parasites of sheep: an in vitro evaluation.

The study evaluated the ovicidal activity of enzymatic extracts of Purpureocillium lilacinum and Trichoderma virens against trichostrongylid eggs from sheep. Filtered extract (FE) and macerated crude extract (MCE) were prepared from fungal cultures in minimal broth. In the experiment, 100 trichostrongylid eggs, obtained from the feces of naturally infected sheep, were exposed to fungal extracts for 24 and 48 hours/25°C.

In vitro anti-Pythium insidiosum activity of amorolfine hydrochloride and azithromycin, alone and in combination.

Pythium insidiosum infections have been widely studied in an attempt to develop an effective therapeutic protocol for the treatment of human and animal pythiosis. Several antifungal agents are still prescribed against this oomycete, although they present contradictory results. To evaluate the susceptibility profile and to verify the morphological alterations in P.

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.

Exposure of Toxocara canis eggs to Purpureocillium lilacinum as a biocontrol strategy: an experimental model evaluation.

Purpureocillium lilacinum is a nematophagous fungus used in biological control against some parasites, including Toxocara canis. This study researched the infectivity of embryonated T. canis eggs after exposure to the fungus P.

In vitro anti-Pythium insidiosum activity of biogenic silver nanoparticles.

Pythium insidiosum belongs to the phylum Oomycota. It is capable of infecting mammals causing a serious condition called pythiosis, which affects mainly horses in Brazil and humans in Thailand. The objective of the present study was to verify the in vitro anti-P.

Risk factors and infection due to Cryptosporidium spp. in dogs and cats in southern Rio Grande do Sul.

This study investigated the frequency of oocysts of Cryptosporidium spp. in feces from dogs and cats in five municipalities in the southern region of the state of Rio Grande do Sul. The risk factors associated with infection were also investigated.

Influence of temperature on in vitro zoosporogenesis of Pythium insidiosum.

This study verified the influence of different temperatures on P. insidiosum in vitro zoosporogenesis. P.

In Vitro Activity of Melaleuca alternifolia (Tea Tree) in Its Free Oil and Nanoemulsion Formulations Against Pythium insidiosum.

Pythium insidiosum is an important aquatic oomycete which can cause pythiosis in both animals and humans. This microorganism shows low susceptibility to antifungal drugs available. This study analyzed the in vitro antimicrobial activity of Melaleuca alternifolia in its free oil (FO) and nanoemulsion (NE) formulations against Brazilian P.

In Vitro Susceptibility of Pythium insidiosum to Melaleuca alternifolia, Mentha piperita and Origanum vulgare Essential Oils Combinations.

Pythium insidiosum is the etiologic agent of pythiosis, a severe and emerging disease that affects mammals. Failure of conventional antifungal therapies is partially justified by the absence of ergosterol in the plasma membrane of this oomycete. Despite research advancement, the treatment of pythiosis has not been not fully established.
