Avaliacao do manejo e estuda da fauna de parasitas de alevinos de tambaqui, em uma represa de terra firme no Amazonas (Brasil), com peixes com idade de sete e oito meses, no meses de junho e julho de 2000. Foram encontradas sete especies de parasitas, porem somente cinco foram identificadas: duas da classe Myxosporida - Myxobolus sp e Henneguya sp, e tres da classe Monogenoidea (somente uma identificada, Linguadactyloides brinkmanni); uma da classe Branchiura, Argulus chicomendesi; e uma da classe Copepoda, Gamidactylus jaraquensis. Os parametros fisico-quimicos da agua apresentaram bons niveis para o cultivo, com excecao do oxigenio dissolvido, que apresentou, no mes de julho, niveis abaixo dos recomendados. |

Twenty-two epitoniid species that live associated with various hard coral species are described. Three genera, viz. Epidendrium gen. nov., Epifungium gen. nov., and Surrepifungium gen. nov., and ten species are introduced as new to science, viz. Epidendrium aureum spec. nov., E. sordidum spec. nov., Epifungium adgranulosa spec. nov., E. adgravis spec. nov., E. adscabra spec. nov., E. marki spec. nov., E. nielsi spec. nov., E. pseudolochi spec. nov., E. pseudotwilae spec. nov., Surrepifungium patamakanthini spec. nov., and ‘Epitonium’ crassicostatum spec. nov. and ‘E.’ graviarmatum spec. nov. Although their identities as separate gene pools are convincingly demonstrated by molecular data, some of these species cannot be identified unequivocally on the basis... |

Abstract Philornis larvae and pupae were collected in nestlings of Neothraupis fasciata (Lichtenstein), the White-banded Tanager (Passeriformes, Thraupidae), in three breeding seasons, between October and November 2003-2005 in a reserve in central Brazil. Here, we present biological data, diagnosis to the recognition of the species and a key to the segregation of species occurring in the Cerrado. The larvae were intradermic in the nestlings and the pupae were collected in the nests after the birds have abandoned them. The immatures collected were taken to the laboratory and reared under laboratory conditions, until emergence. The species identified as Philornis torquans (Nielsen), is here firstly recorded from the Brazilian Cerrado, and firstly recorded... |

The infection of the estuarine teleost fishes Mugil gaimardianus Desmarest, 1831 (Mugilidae), Arius phrygiatus Valenciennes, 1839 (Ariidae), Conodon nobilis Linnaeus, 1759 (Haemulidae), Cetengraulis edentulus Cuvier, 1829 (Engraulidae), and Anableps anableps Linnaeus, 1758 (Anablepidae) by praniza larvae of Gnathiidae (Crustacea, Isopoda) was studied in specimens fished off the Atlantic Ocean in Northeast of Pará State, near Bragança, Brazil. The highest infection prevalence value was found in Anableps anableps (42.3%) and the lowest in Conodon nobilis (9.1%). The mean intensity varied from 1 parasitein Conodon nobilis to 19.5 in Arius phrygiatus. A description of the larvae is provided. The morphology of the mouthparts is related to the blood sucking... |

Introducción: las infecciones causadas por protozoos del género Leishmania constituyen un problema de salud mundial con una alta prevalencia en países subdesarrollados. En la actualidad no existe una vacuna contra esta enfermedad y el tratamiento utilizado es deficiente, por lo que la búsqueda de medicamentos más efectivos y seguros constituye una urgente necesidad. Objetivo: evaluar la actividad antileishmanial in vitro de 6 extractos acuosos e hidroalcohólicos de organismos marinos. Métodos: se determinó la actividad frente a promastigotes y amastigotes de Leishmania amazonensis, así como su toxicidad frente a macrófagos peritoneales de ratones BALB/c. Resultados: en el ensayo de promastigotes los extractos de Bryothamnion triquetrum, Bunodosoma... |

ABSTRACT: Liquid pig manure (LPM) is widely used as a compost fertilizer for vegetable crops destined for human consumption. However, these wastes may contain parasites eggs, such as the nematode Ascaris suum, that pose serious health risks to humans. We attempted to determine the most appropriate technique for recovering A. suum eggs from LPM compost. Samples were collected from two waste sources during composting, including 23 samples containing LPM, sawdust, and wood shavings, and 14 samples of LPM alone-both in triplicate. Samples were analyzed using several different recovery methods. Recovery of eggs by the modified Bailenger method with adaptations was significantly more effective and recovered 57% more eggs than by the modified Bailenger method... |

This study evaluated the efficacy of albendazole, ivermectin, levamisole, mebendazole and praziquantel on monogeneans of Colossoma macropomum, based on in vitro and in vivo assays. In vitro assays indicated that albendazole (500, 100, 1,500 and 2,000 mg/L), ivermectin (200, 250, 300 and 350 mg/L) and levamisole (50, 75, 100 and 125 mg/L) were 100% effective against Anacanthorus spatulatus, Notozothecium janauachensis, Mymarothecium boegeri and Linguadactyloides brinkmanni, while mebendazole (125, 150, 175 and 200 mg/L) and praziquantel (5, 10, 15 and 20 mg/L) were ineffective. Fish mortality in 24 hr therapeutic baths with 500 mg/L of albendazole was 6.6%, but the behaviour of the animals remained unchanged, while 200 mg/L of ivermectin caused lethargy,... |

A disease whose severity seems directly bound to conditions of cultivation can cause a heavy mortality in the common prawn Palaemon serratus (Pennant) at molting. The causative agent, A. rodor, is a ciliate, a common external parasite whose life cycle is adapted to the molting cycle of the shrimp. The principal factors favorable to the development of the parasite were studied: age of the host, water temp, numbers of shrimps as a function of the quantity of water and its renewal. The sp A. rodor, although related to the Conidophryidae, Kirby, 1941 (1936) has significant differences (1) in its ethology (it feeds on the exoskeleton without penetrating to its hosts' tissues), (2) in its vegetative multiplication (tomitogenesis combines the cortical... |
