Journal ArticleDOI
Antiparasitic activity of the essential oil of Lippia alba on ectoparasites of Colossoma macropomum (tambaqui) and its physiological and histopathological effects
Bruna Viana Soares,Ligia Rigôr Neves,Marcos Sidney Brito Oliveira,Francisco Célio Maia Chaves,Márcia Kelly Reis Dias,Edsandra Campos Chagas,Marcos Tavares-Dias +6 more
TL;DR: The essential oil of L. alba showed great potential for antiparasitic treatment, given that it had high in vitro efficacy against monogenoideans and in vivo efficacy against the protozoon I. multifiliis.
Journal ArticleDOI
Seasonal Influence on the Parasite Fauna of a Wild Population of Astronotus ocellatus (Perciformes: Cichlidae) from the Brazilian Amazon
TL;DR: Seasonality was a strong determinant in the parasite community structure of Astronotus ocellatus, and may represent a link in food-web transmissions for parasites because it is used both as definitive and intermediate host.
Journal ArticleDOI
Helminthes and protozoan of farmed pirarucu (Arapaima gigas) in eastern Amazon and host-parasite relationship
R. G. B. Marinho,R. G. B. Marinho,Marcos Tavares-Dias,M K R Dias-Grigório,M K R Dias-Grigório,Ligia Rigôr Neves,E. T. O. Yoshioka,Cheila de Lima Boijink,Ricardo Massato Takemoto +8 more
TL;DR: This study is the first to record the occurrence of P. macrorhynchus in A. gigas farmed in Amazon, and the number of I. multifiliis was positively correlated with the weight and total length of hosts, while the intensity of monogenoideans was negatively correlated with body weight andtotal length.
Journal ArticleDOI
Fauna parasitária de tambaqui Colossoma macropomum (Characidae) cultivado em tanque-rede no estado do Amapá, Amazônia oriental
E. F. Santos,Marcos Tavares-Dias,Douglas Anadias Pinheiro,Ligia Rigôr Neves,R. G. B. Marinho,M. K. R. Dias +5 more
TL;DR: Evaluated the parasitic fauna and the host-parasite relationship in Colossoma macropomum farmed in cages of Matapi River, municipally of Santana, State of Amapa, in eastern Amazon, Brazil, finding higher infestation levels were caused by protozoans I. multifiliis and P. pillulare and no effects of parasitic infestation rates on fish health were observed.
Journal ArticleDOI
Antiparasitic activity, histopathology and physiology of Colossoma macropomum (tambaqui) exposed to the essential oil of Lippia sidoides (Verbenaceae).

TL;DR: The bioactive potential of its main chemical components should be investigated, as well as more efficient forms of its administration in therapeutic baths in order to eliminate fish parasites.
