Parasitological and hematological aspects of co-infection with Angiostrongylus vasorum and Ancylostoma caninum in dogs.

Dogs are frequently infected by one or more species of endoparasites, which can lead to secondary infections that cause high morbidity and death. In this context, 2 nematode species are of veterinary importance: Angiostrongylus vasorum, which is a parasite of the pulmonary artery and right ventricle in domestic and wild canids, and Ancylostoma caninum, which is a parasite of the small intestine in felids and domestic and wild canids. We used 20 mongrel dogs that were divided into groups and infected as follows: Group A included 5 uninfected dogs, Group B included 5 dogs infected with A.

Optimization of protease production by the fungus Monacrosporium thaumasium and its action against Angiostrongylus vasorum larvae.

The objectives of this study were to optimize protease production from the nematophagous fungus Monacrosporium thaumasium (NF34a) and evaluate its larvicidal activity and biological stability. An isolate of the nematophagous fungus Monacrosporium thaumasium (NF34a) was used to produce the enzyme. The Plackett-Burman design was used in order to scan which components of the culture medium could have a significant influence on protease production by the fungus NF34a.

In vitro predatory activity of conidia of fungal isolates of the Duddingtonia flagrans on Angiostrongylus vasorum first-stage larvae.

Introduction: Angiostrongylus vasorum is a nematode that parasitizes molluscs, dogs, and even man.

Methods: The objective was to evaluate the predatory activity of the conidia of two fungal isolates of Duddingtonia flagrans (AC001 and CG722) on first-stage larvae (L1) of A. vasorum in laboratory conditions.

[Larvicidal activity of a crude enzyme extract of the fungus Duddingtonia flagrans on first-stage larvae of Angiostrongylus vasorum].

Introduction: Angiostrongylus vasorum is a nematode parasite of domestic dogs and potentially of humans.

Methods: This study aimed to observe the predatory activity in vitro of a crude enzyme extract of the fungus Duddingtonia flagrans on first-stage larvae of A. vasorum in laboratory conditions on 2% water-agar.
