One example of the use of parasites as an effect indicator is the Monogenean Trematode, which lives on the gills of fish. Because this parasite is in direct contact with both the surrounding environment and the host fish, it is a particularly good indicator species.   Advantages to parasites that have the ability to retract their anterior adhesive areas or those that possess a cavity or reservoir behind each adhesive outlet (e.g. Cribb et al., ) include: the ability for two or more different secretory types to mix before release to the substrate; provision of space to store adhesive immediately prior to.

parasites were found in the members of Cobitidae, Atherinidae, Poecilidae and Sygnathidae. A total of 13 monogenean species were identified (see Table 1). The data on monogenean parasite list with their hosts is presented in Table 1 and representatives of the monogenean species are illustrated in.

Introduction. Sperm ultrastructure has been used as a source of significant characters to elucidate phylogenetic relationships in the Platyhelminthes [20,21], and especially in the parasitic Platyhelminthes or was the case for the Neodermata as a whole [35,39,42], the Cestoda [2,29,41,67], the Digenea ([6,39] and many recent references, e.g.

Journal of Aquatic Biology and Fisheries, 7, – Parasitology is the study of parasites, their hosts, and the relationship between a biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology.

The capsalid monogenean Neobenedenia melleni is a parasitic skin fluke of fish worldwide. Unlike most monogenean parasites, N. melleni is notorious for its lack of host-specificity. In Japan, Neobenedenia girellae infections to cultured Japanese flounder and cultured.

Summary. The aim of this study was to investigate the use of the anaesthetic 2-phenoxyethanol on the transmission factors of gyrodactylid and to ascertain how this may affect in the colonisation of new hosts using the Gyrodactylus gasterostei Gläser, - Gasterosteus aculeatus L. model which is a simple and successful system to examine aspects of transmission of parasites from live and.

The mechanisms of action of silver nanoparticles (AgNPs) in monogenean parasites of the genus Cichlidogyrus were investigated through a microarray hybridization approach using genomic information from the nematode Caenorhabditis elegans.

The effects of two concentrations of AgNPs were explored, low (6 µg/L Ag) and high (36 µg/L Ag). Parasite-host trophic fractionation patterns for both 13 C and 15 N were significantly different when comparing the two different types of parasites (i.e., copepods vs.

monogeneans) collected from the same host species as well as when comparing the same species of parasites (C. atromaculatus) collected from the two different species of hosts (A.

This parasite is commonly considered to be the marine counterpart of Ichthyophthirius multifiliis, causative organism of the "ich "or "white spot" diseases of freshwater fish. The surface of fish affected with cryptocaryoniasis has numerous macroscopic white - grey spots, which contain the feeding parasites, which have invaded beneath the.

The epidermis of Gyratrix hermaphroditus can be described as semi‐syn‐cytial. Its ultrastructure is characterized by microvilli and cilia with two strong rootlets perpendicular to each other. The apical part of the epithelium contains mitochondria and vacuoles.

The basal synthesizing layer is provided with cell boundaries, at least between the type II penetrating receptors in the anterior. The journal Parasitology Research covers the latest developments in parasitology across a variety of disciplines, including biology, medicine and veterinary medicine.

Introduction. Parasitology or Monogenean Group research topics are: Morphology, taxonomy, biology and distribution of monogeneans parasitizing fish, Organismal and molecular diversity of monogenean parasites, Population and community ecology of metazoan parasites of fish, especially monogeneans, Evolutionary ecology of metazoan parasites of fish, Diversity analysis of different parasite - host.

The surface structures and gland cells of the posterior rosette organ of Gyrocotyle urna Grube et Wagener,a member of the group presumed to be the most basal of the tapeworms (Cestoda: Gyrocotylidea), was studied by scanning electron an.

Intrinsic and extrinsic factors responsible for niche restriction in parasites and particularly in Monogenea of fish are discussed. Interspecific competition may result in competitive exclusion of one or several species, or it may lead to a change in the microhabitat of one or all co-occurring species (interactive site segregation), but there is no evidence that such effects lead to.

The unparalleled biodiversity of Lake Tanganyika (Africa) has fascinated biologists for over a century; its unique cichlid communities are a preferred model for evolutionary research.

Although species delineation is, in most cases, relatively straightforward, higher-order classifications were shown not to agree with monophyletic groups.
