In vitro antiparasitic and antibacterial evaluation of organic extracts of Salvadoran flora

Currently, in developing countries, parasitic and bacterial diseases as amebiasis, giardiasis, trichonomiasis, leishmaniasis, trypanosomiasis, tuberculosis, and nocardiasis are a public health problem. The pharmacological treatment for these diseases is not completely effective and c...

Protótipos microbianos como candidatos a fármacos para protozooses negligenciadas

Doenças tropicais negligenciadas atingem cerca de 1,7 bilhões de pessoas, gerando um forte impacto na economia e problemas na Saúde Pública. Dentre as endemias mais negligenciadas, encontra-se a doença de Chagas, que afeta cerca de 6 milhões de pessoas, e no Brasil, dispõe-se de apenas de um fárm...

The sensitivity of Demodex canis (Acari: Demodicidae) to the essential oil of Melaleuca alternifolia - an in vitro study

Abstract The essential oil of the Melaleuca alternifolia (Maiden & Betche) (tea tree oil) has been effective in previous studies, in the treatment of infestation by Demodex mites in humans. The present study aimed at evaluating the in vitro acaricidal effect of this herbal medicine on Demodex canis. ...

Differences in protein expression associated with ivermectin resistance in Caenorhabditis elegans

Abstract The indiscriminate administration of synthetic anthelmintics such as ivermectin contributes to the selection of subpopulations capable of resisting the drugs' effects. To understand the mechanisms of ivermectin resistance in Caenorhabditis elegans, this study attempted to identify molecular tar...

In vitro evaluation of ivermectin, moxidectin, albendazole and pyrantel against cyathostomins of horses

Abstract Cyathostomins are the most prevalent nematodes of horses, and multidrug resistance has been reported worldwide. There is a need to implement alternative drug monitoring analytical tests. The objective of this study was to determine the consistency (5 repetitions) of the larval migration on agar ...

In vitro susceptibility of nematophagous fungi to antiparasitic drugs: interactions and implications for biological control

Braz. j. biol; 77 (3), 2017
Abstract The fast anthelmintic resistance development has shown a limited efficiency in the control of animal's endoparasitosis and has promoted research using alternative control methods. The use of chemicals in animal anthelmintic treatment, in association with nematophagous fungi used for biological c...

Antiparasitic drugs: in vitro tests against nematophagous fungi

Braz. j. biol; 76 (4), 2016
Abstract The use of biological agents has been intensified in recent years against eggs and larvae of gastrointestinal nematodes as an alternative control method in pasture plant health management, with the concomitant use with antiparasitic drugs still occurring. The aim of this study was to test the in...

Dung removal by dung beetles (Coleoptera: Scarabaeidae) and macrocyclic lactone use on cattle ranches of Yucatan, Mexico

Rev. biol. trop; 64 (3), 2016
Abstract:The expanded use of macrocyclic lactones (ML) to treat endo- and ectoparasites in cattle in tropical regions, can reduce dung beetle populations, and thus interrupt the dung removal process in cattle pasture ecosystems. During the reproductive period (the rainy season) of two functional groups o...

Pneumonia eosinofílica: relato de um caso
Eosinophilic peneumonia

CCS; 13 (3), 1994
Os autores relatam um caso de peneumonia eosinofílica, com manifestaçöes clínicas inespecíficas com tosse, dispnéia e febre, além de sinais físicos de broncoespasmos de leve intencidade. O quadro clínico-radiológico de evoluçäo mais demorada que o habitual constitui-se em aspecto atípico na ...
