A fauna de parasitas e patologias de alevinos do tambaqui, Colossoma macropomum (Cuvier, 1818) cultivados em uma represa na Amazônia Central. Repositório Alice
BEZERRA, S. C..
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.

A new host for Philornis torquans (Diptera, Muscidae) from the Brazilian Cerrado Pap. Avulsos de Zool. (São Paulo)
Couri,Márcia Souto; Barbosa,Leandro; Marini,Miguel Ângelo; Duca,Charles; Pujol-Luz,José Roberto.
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...

Adapted Bailenger method improves the rate of Ascaris suum eggs recovery from liquid pig manure compost Ciência Rural
Sá,Mariangela Facco de; Gonçalves,Ricardo Aymay; Marder,Cristiana; Baldissera,Matheus Dellamea; Oliveira,Camila Belmonte de; Noll,Jessica Caroline Gomes; Silva,Filipe; Monteiro,Silvia Gonzalez.
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...

Alternativas para o controle de ectoparasitas em bovinos da raça Canchim. Repositório Alice
OLIVEIRA, M. C. de S..
As doenças parasitárias são consideradas fatores que limitam a produção animal em todo o mundo e, embora raramente associadas à alta mortalidade, determinam um expressivo impacto econômico em razão da redução da produtividade e dos aumentos dos custos de controle (FAO, 2004). Essa situação tende a ser mais grave em regiões tropicais, como é o caso da maior parte do território brasileiro, onde as condições climáticas favoráveis contribuem para aumentar os problemas decorrentes do parasitismo.

Analyse du compartiment mésozooplanctonique et écologie alimentaire printanière de la sardine, Sardina pilchardus (Walbaum, 1782), et de l’anchois, Engraulis encrasicolus (Linné, 1758) adultes dans le Golfe de Gascogne ArchiMer
Dessier, Aurélie.
Dietary studies of marine species constitute an important key to improve the understanding of its biology and of its role in the ecosystem. Thus, prey-predator relationships structure and determine population dynamics and the trophic network at the ecosystem scale. Among the major study sites, the marine ecosystem is submitted to natural and anthropogenic constraints. In the North-Eastern part of the Atlantic Ocean, the Bay of Biscay is a large open area surrounded South by Spain and East by France. This bay is an historic place of intense fishery activities for which the main small pelagic species targeted are the pilchard, Sardina pilchardus and the anchovy, Engraulis encrasicolus. The aim of this work is to analyze the trophic ecology of these two small...

Apoptosis in parasites and parasite-induced apoptosis in the host immune system: a new approach to parasitic diseases BJMBR
Barcinski,M.A.; DosReis,G.A..
Apoptosis, a form of programmed cell death (PCD), has been described as essential for normal organogenesis and tissue development, as well as for the proper function of cell-renewal systems in adult organisms. Apoptosis is also pivotal in the pathogenesis of several different diseases. In this paper we discuss, from two different points of view, the role of apoptosis in parasitic diseases. The description of apoptotic death in three different species of heteroxenic trypanosomatids is reviewed, and considerations on the phylogenesis of apoptosis and on the eventual role of PCD on their mechanism of pathogenesis are made. From a different perspective, an increasing body of evidence is making clear that regulation of host cell apoptosis is an important factor...

Ascophrys rodor (Campillo and Deroux) parasite of the reared common prawn P. serratus). ArchiMer
Deroux, G.; Campillo, Albert; Bradbury, Ph. C..
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...

El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

Biology of a trap-nesting wasp of one species the ground-nesting Liris (Hymenoptera: Crabronidae) from the Atlantic Forest of southern Brazil Rev. Bras. Zool.
Costa,Camila Cristina Ferreira da; Buschini,Maria Luisa Tunes.
ABSTRACT Studies on the nesting biology of Liris are restricted to a few notes and observations on ground-nesting species. There are no studies of this kind about Brazilian species. We investigated and described the nesting biology of Liris sp. obtained by trap-nests that were installed at an area of Atlantic Forest vegetation (25°10'S, 48°18'W) in southern Brazil. The nests of Liris sp. are built with a variety of plant debris. They usually have one cell, but may have up to two. Nests do not show vestibular or intercalary cells. Immatures have a hard cocoon made with the silk they produce, mixed with the fine sand and sawdust left by the adult female at the bottom of the cell. No nest parasites were observed. The wasps did not go through diapause at the...
