Occurrence of nematodes and anthelmintic management of ostrich farms from different Brazilian states: Libyostrongylus douglassii dominates mixed infections.
TLDR
Ostriches were imported to Brazil in the early 1990s without appropriate parasite control leading to a co-importation of parasites, proving that this mixed infection in Brazilian ostrich's farms is common. Expand
Anthelmintic efficacy and management practices in sheep farms from the state of Rio de Janeiro, Brazil.
TLDR
The present work illustrates the alarming lack of efficacy of drugs even in an area new to sheep farming, and is important to establish alternative strategies of management in a broad program of parasite control for reducing the selection pressure on parasites by the commercially available anthelmintics. Expand
Morphological diagnosis of infective larvae of Libyostrongylus douglassii (Cobbold, 1882) Lane, 1923 and L. dentatus Hoberg, Lloyd and Omar, 1995 (Nematoda: Trichostrongylidae) of ostriches.
TLDR
It is confirmed that it is possible to differentiate the infective larvae of L. douglassii and L. dentatus allowing the differential diagnosis of these species by fecal culture, and will facilitate the diagnosis of both species for further understanding the Libyostrongylus biology. Expand
Mixed infection with Libyostrongylus dentatusandLibyostrongylus douglassii induces a heterophilic inflammatory infiltrate in the proventriculus of ostriches
TLDR
Analysis of the collected nematodes confirmed a mixed infection in the proventriculus of examined birds and showed an inflammatory infiltrate composed of granular cells in close proximity to the nematode. Expand
Occurrence of Libyostrongylus sp. (Nematoda) in ostriches (Struthio camelus Linnaeus, 1758) from the north region of the state of Rio de Janeiro, Brazil.
Domestic production of ostrich in Brazil started in the beginning of the last decade, but its sanitary state has not been reported. Libyostrongylus sp. is an ostrich specific nematode whoseExpand
Population dynamics of Libyostrongylus dentatus and L. douglassii of ostriches raised in the Northern Rio de Janeiro State, Brazil.
TLDR
The population dynamics of both species from two ostrich farms located in the northern region of the state of Rio de Janeiro, Brazil found the highest values of EPG were associated with the rainy season on both farms, however, only on farm 1 the rainySeason correlated statistically with EPG. Expand
Kinetics of capture and infection of infective larvae of trichostrongylides and free-living nematodes Panagrellus sp. by Duddingtonia flagrans
TLDR
It was possible to verify that the process of trap formation and capture occurs quickly when both nematodes were tested, suggesting that the organisms would eventually be killed once in contact with the fungi encouraging the use of the fungus as a biological control agent. Expand
Overview of anthelmintic resistance of gastrointestinal nematodes of small ruminants in Brazil.
TLDR
Molecular studies can be underpinned by the analysis of field studies, such as the maintenance of antiparasitic effectiveness over time and the mechanisms involved in this process, and the most widely studied species is sheep, for which the widest range of drugs is also evaluated. Expand
Efficacy of albendazole and moxidectin and resistance to ivermectin against Libyostrongylus douglassii and Libyostrongylus dentatus in ostriches.
TLDR
The efficacy of albendazole, ivermectin and moxidectin were evaluated against the hematophagous nematodes in ostriches, Libyostrongylus dentatus and L. douglassii in an ostrich farm in Minas Gerais state, Brazil to determine possible resistance against the drugs used. Expand
Predatory activity of Arthrobotrys oligospora and Duddingtonia flagrans on pre-parasitic larval stages of cyathostominae under different constant temperatures
TLDR
The two species of fungi tested showed to be efficient in reducing the number of L3 when mixed with equine feces and maintained at the same temperature for the development of larval pre-parasitic stages of cyathostomes. Expand
