| Dix stations côtières ont été prospectées dans la lagune de Bizerte en hiver 2001 pour étudier l’impact des conditions environnementales sur les plans morphométrique, trophique et de maturité des nématodes méiobenthiques. Nos résultats montrent que la croissance en largeur des nématodes libres a été proportionnelle aux charges sédimentaires en fraction fine et en métaux et ce parallèlement à l’individualisation de quatre morphotypes nématologiques. D’autre part, la structure trophique de la nématofaune est liée à la turbidité et aux concentrations des eaux en nitrites. En effet, la proportion en détritivores sélectifs, principalement bactériophages, au sein des communautés nématologiques, est positivement corrélée à la concentration des eaux en nitrites et... |

| Une étude en microcosme a été entreprise pour examiner l’influence d’un métal lourd (le cadmium) et/ou du diesel sur la structure trophique d’une communauté de nématodes libres provenant de la lagune de Ghar El Melh (Tunisie). Trois doses en cadmium [faible : 0,54 mg Cd kg-1 (poids sec, ps), moyenne : 0,90 mg Cd kg-1 (ps) et forte : 1,40 mg Cd kg-1(ps)], une dose de diesel de 0,25 mg kg-1 (ps) et un mélange de cadmium et de diesel [1,40 mg Cd kg-1(ps) + 0,25 mg kg-1 de diesel (ps)] ont été testées pour évaluer les effets de ces polluants après 90 jours d’exposition. Les résultats des analyses statistiques univariées n’ont montré aucune différence significative pour la plupart des indices des communautés traitées par rapport à l’assemblage témoin. Ainsi,... |

| The objective of this work was to clarify whether the method to extract nematodes from European soils is suitable for forest soils and litter in the eastern of Paraná state, Brazil, and whether nematode abundance differs between sites with different ecosystems and levels of human interference. The study sites were situated in the coastal area of the Serra do Mar, near the town of Antonina, in Eastern Paraná, Brazil. Cobb's sieving and decanting method was more appropriate than ISO method, since extraction efficiency was higher and intra-sample variability was significantly lower. In order to achieve an extraction efficiency higher than 90%, Cobb's method was modified. For the extraction of nematodes from litter, the Baermann funnel, with an extraction time... |

| ABSTRACT Brazilian poultry production is growing, mainly due to the cost and benefit that chicken meat provides. The importance of free-range chickens and the susceptibility, to which they are exposed, makes it necessary to know about gastrointestinal parasites and the consequences that large infections can cause for them as such as weight loss. The present study aimed to determine the occurrence of gastrointestinal parasites in free-range hens raised in an extensive regime in the municipality of Santa Rita, state of Maranhão, Brazil. The studied population was composed of adult chickens (Gallus gallus domesticus) acquired from slaughterhouses in the region. The gastrointestinal organs of each chicken were separated and subsequently conditioned in flasks... |

| Este trabalho teve o objetivo de conhecer como o nematóide Bursaphelenchus cocophilus tende a se distribuir no interior das plantas de coqueiros em estágios avançados da doença anel-vermelho. Nas amostras de raízes coletadas junto à base da estipe de coqueiros doentes, o número de nematóides foi consideravelmente maior que encontrado em raízes situadas entre um e três metros de distância da estipe. Observou-se que, à medida que se afasta da estipe, a possibilidade de encontrar nematóides na raiz é mínima, de forma que as chances de transmissão da doença, de uma planta para outra, através das raízes, devem ser muito pequenas. Na região do palmito, onde o tecido é mais tenro, é possível encontrar o nematóide tanto nas áreas avermelhadas quanto nas áreas... |

| ABSTRACT There are few studies about parasitic infections in Crotalus triseriatus (Wagler, 1830), an endemic rattlesnake from the highlands of central Mexico. This species occupies several habitats, from conserved forested regions to heavily impacted landscapes. To increase the parasitological knowledge of this reptile species without impacting populations, we obtained fecal samples of 16 rattlesnakes between 2012 and 2014 from Toluca Valley, Mexico. By using flotation technique, we found oocysts of Eimeria sp. and eggs of Capillariidae sp. The most frequent parasite was Eimeria sp. (62.5%). This study provides the first records of occurrence of parasites in reptilian feces from Mexico. Our results may be important for wildlife conservation purposes, for... |

| The species Ophidascaris durissus sp. nov. is proposed with basis on specimens recovered from the rattlesnake Crotalus durissus L., 1758 (type host) captured in Foz do Iguaçu, Brazil (type locality). By the lack of interlabia, the new species can be compared only to O. natricis Yamaguti, 1935 from Japan and O. freitasi Hoa & Lien, 1970, from Vietnam. However, O. durissus sp. nov. differs from O. natricis mainly by the absence of internal lip papillae, location of the vulvar aperture and length of the spicules; from O. freitasi mostly by the greater number of pre-cloacal and distribution of post-cloacal papillae. |

| A new species of Ophidascaris Baylis, 1920 is described on the basis of specimens recovered from the pit viper Bothrops jararaca Wied, 1824 in Brazil. The new species referred here was compared to other of the genus that are the closest. The differentiation was based on reliable morphological characters, mainly on what refers to the spicular length, number and distribution of caudal papillae, location of the vulvar opening, eggs size and aspect of the labial indentations. Moreover, female specimens are the only to possess a most prominent and characteristic post-anal tubercle-like structure and when analyzed together with the males, that show a great number of pre-cloacal papillae, the presence of an unpaired papilla and also of a less conspicuous... |

| ABSTRACT In the Amazon, the growing demand for fish has been boosting the expansion of fish farms. However, the intensification of cultivation can generate disequilibrium in the parasite-host environment, predisposing fish to parasitic infections. The objective of this study was to evaluate the community structure of metazoan parasites in cultivation systems of piauçu, Leporinus macrocephalus, in the state of Acre, Brazil. We examined 100 specimens from a semi-intensive cultivation system (earth tanks) and 100 from an extensive system (dams). Overall 66.5% of the hosts were parasitized. We collected 1,240 parasite specimens, classified in 15 metazoan taxa (10 monogenoidean, one digenean and four nematodes). The parasite prevalence was higher by... |

| Nenhum estudo de peixes e parasitos foi realizado, até o momento, no Lago do Parque do Ingá que sofre influências antrópicas desde seu represamento, em 1970. Este trabalho analisou alguns aspectos ecológicos dos parasitos metazoários dos peixes deste lago. Dos peixes analisados, (69,5%) estavam parasitados por pelo menos uma espécie de parasito. Foram encontrados 1.372 parasitos pertencentes à Nematoda (larvas) e Platyhelminthes (Monogenea e Cestoda), sendo estes os mais prevalentes e numerosos. O encontro de larvas de cestóides em Tilapia rendalli e Oreochromis niloticus confirma a importância destas espécies como participantes de níveis tróficos intermediários. A maior abundância de T. rendalli e O. niloticus, no local, pode ser um fator determinante no... |

| Abstract: Lutjanids are marine fish and commonly inhabit coral reefs, which have migratory habits and feed in a general way, due to these characteristics, are susceptible to infections by parasites, such as cuculanid nematodes. This work aimed to report for the first time, the occurrence of Dichelyne (Dichelyne) bonacii in Brazil, in two new hosts, Lutjanus analis and Rhomboplites aurorubens, acquired from local artisanal fishermen at the Aracaju city public fishing terminal (10 ° 54’17 “S37 ° 2’56” W), northeast coast of Brazil. Adult nematodes were collected from the intestinal tract of the hosts, clarified in Aman’s Lactophenol and were briefly described here. Three adult males and five gravid females were found, indicating that the two species of fish... |
