The chemical composition of the essential oils Mentha arvensis and piperita their antimicrobial activity against twelve Aeromonas spp. isolates from tambaquis (Colossoma macropomum), an important native farmed fish species in Brazil, were evaluated. characterized using gas chromatography mass spectrometry (GC/MS) was evaluated through microdilution method. these mainly comprised oxygenated monoterpenes (97.1% for M. 86.2% piperita) menthol major compound (86.1% 33.8% piperita). It confirmed...

The record of occurrence acanthocephalan parasites on tambaqui farms in Northern Brazil has increased recent years along with reports associated economic losses, justifying further epidemiological studies this parasite. As such, study evaluated the Neoechinorhynchus buttnerae and parasite-host relationship (Colossoma macropomum) from three fish Amazonian town Rio Preto da Eva, Brazil. Fish (N = 18 per farm) were collected for parasitological examination, determination relative condition...
The aim of this study was to evaluate the antimicrobial activity Lippia sidoides, Ocimum gratissimum and Zingiber officinale's essential oils against Aeromonas spp. isolates from Colossoma macropomum, determine their chemical composition. Essential were obtained through hydrodistillation composition analyzed using gas chromatography coupled mass spectrometry. evaluated by minimum inhibitory concentration (MIC) bactericidal (MBC). major compounds thymol (76.6%), p-cymene (6.3%) (E)-...
This study aimed to evaluate the effects of essential oil (EO) Lippia sidoides, Ocimum gratissimum, and Zingiber officinale in diet tambaqui (Colossoma macropomum) growth, hematological immunological parameters. The survival rate was also calculated after challenge with Aeromonas hydrophila. Seven diets containing 32 % crude protein were formulated as follows: control (0 g/kg EO), 0.625 1.25 L. sidoides EO; 5.0 O. gratissimum Z. EO, triplicate. Tambaqui fed supplemented EO did not present...
The objective of this study was to evaluate the antimicrobial activity essential oils from five Brazilian Piper species (Piper aduncum, callosum, hispidinervum, hispidum and marginatum) against strains Aeromonas hydrophila, isolated tambaqui (Colossoma macropomum), as well their chemical composition. were characterized by gas chromatography mass spectrometry (GC/MS), major compounds identified were: dillapiole (80.7 %) for P. aduncum; safrole (67.0 %), methyl-eugenol (7.2 β-pinene (6.6...
O Arapaima gigas (Schinz, 1822) é um peixe que habita os rios amazônicos, de suma importância ecológica, e por apresentar elevado valor comercial sobrepesca, corre risco extinção. Além disto, atrativo para a piscicultura devido ao bom rendimento zootécnico. Um dos entraves produção do pirarucu em cultivo são as doenças parasitarias intervém na quantidade qualidade peixes cultivados. Os endoparasitas, como nematodos, alimentam-se nutrientes já processados pelo hospedeiro podem causar...
Na criação de tambaqui ( Colossoma macropomum ) endoparasitos intestinais vem chamando a atenção pelo aumento casos em peixes cultivados na região norte do Brasil. Este estudo investigou eficácia in vitro dos óleos essenciais (OEs) quatro espécies plantas da família Piperaceae, sendo elas; Piper hispidinervum, hispidum, marginatum e callosum , no controle acantocéfalo Neoechinorhynchus buttnerae que acomete o tambaqui. As concentrações testadas OE foram: 0,19; 0,39; 0,78; 1,56; 3,125; 6,25;...
Óleos essenciais podem ser usados como anestésicos naturais para peixes em diversos procedimentos laboratoriais ou de rotina da piscicultura. Vários são considerados seguros tanto os o ambiente. Entretanto, seus efeitos redutores estresse necessitam avaliados. O transporte é uma das práticas manejo piscicultura mais estressantes. nos pode induzir a consequências indesejáveis manifestações doenças e mortalidades. Este estudo avaliou do óleo essencial Ocimium gratissimum parâmetros...
Among the aetiological agents involved in bacterial diseases fish culture, Aeromonas hydrophila stands out, with use of bioactive potential plants as an alternative for its control, replacing antibiotics. Several biological properties have been attributed to essential oil and extracts Lippia sidoides ( Cham.) Verbenaceae. Thus, objective this study was evaluate antibacterial activity oil, aqueous ethanolic extract L. , well major compound against A. . For this, obtained by contacting crushed...
