Evaluation of Methylene Blue as An Effective Antiseptic for Medicinal Leeches ().

Objective: Medicinal leeches ( spp.) have been used for therapeutic purposes in humans since ancient times. Because of their growth conditions, leeches carry certain bacteria and endosymbionts (e.

Ice-inhabiting species of Bdelloidea Rotifera reveal a pre-Quaternary ancestry in the Arctic cryosphere.

Historical climate data indicate that the Earth has passed through multiple geological periods with much warmer-than-present climates, including epochs of the Miocene (23-5.3 mya BP) with temperatures 3-4°C above present, and more recent interglacial stages of the Quaternary, for example, Marine Isotope Stage 11c (approx. 425-395 ka BP) and Middle Holocene thermal maximum (7.

Transcriptomic Profiling at the Maternal-to-Zygotic Transition in Leech, .

The glossiphoniid leech, , is an experimentally tractable member of the superphylum, Lophotrochozoa. Its large embryonic cells, stereotyped asymmetric cell divisions and ex vivo development capabilities makes it a favorable model for studying the molecular and cellular events of a representative spiralian. In this study, we focused on a narrow developmental time window of ~6-8 h, comprising stages just prior to and immediately following zygote deposition.

Biocontrol of snail-borne parasites with the glossiphoniid leech, .

Parasites in which freshwater snails are intermediate hosts pose a serious threat to human health worldwide. We show here that freshwater snails can potentially be controlled by leech predation; in principle, this approach could significantly reduce snail-borne parasitic diseases (SBPDs). Specifically, glossiphoniid leeches, and congener species consume freshwater snails indiscriminately, while other common leeches do not.

Detailed ultrastructure of the Hirudo (Annelida: Hirudinea) salivary gland.

Medical leeches have been widely used in medical applications and treatments for millennia. Studies on the salivary glands of blood-sucking leeches have focused on their bioactive secretions and mechanisms of action, with little attention to ultrastructure. In this study, we examined dissected embryonic and adult Hirudo verbana salivary glands by scanning electron microscopy (SEM).

Internal and External Morphological Characteristics of the Medicinal Leech Species and .

Objective: The aim of this study was to investigate the internal and external morphological structures of two species of medicinal leeches ( and ).

Methods: Leech specimens were collected from various regions of Turkey between the years of 1995-2016. The leeches were first examined alive and later were stunned with 10% ethyl alcohol and fixed in 70% ethyl alcohol or 4% formaldehyde.

Correct spelling of a recently described species of Helobdella (Annelida: Clitellata: Hirudinea).

In a recently published article (Saglam et al. 2018) the name of a new species of Hirudinea (Annelida, Clitellata) was simultaneously published in three different ways, as Helobdella serendipitious (Saglam et al. 2018: 61, 70, 71, 73), Helobdella serendipitous (ibid.

Phylogenetic and morphological resolution of the Helobdella stagnalis species-complex (Annelida: Clitellata: Hirudinea).

The glossiphoniid freshwater leech, Helobdella stagnalis, was described by Linnaeus 1758 based on common European specimens. The presence of a brown, chitinous scute on the dorsal-anterior surface, as observed on leeches elsewhere in the world, has generally led to the classification of all scute-bearing members of the genus as H. stagnalis.

Phylogeny and cocoon production in the parasitic leech Myzobdella lugubris Leidy, 1851 (Hirudinidae, Piscicolidae).

Myzobdella lugubris is a commensal leech on crustaceans and a parasite to fishes, surviving predominantly in brackish waters throughout North America. Specimens in this study were collected within the tidal zone of the Delaware River basin (New Jersey and Pennsylvania). To compare regional M.

Elaborate ultrastructure of the Hirudo (Annelida: Hirudinae) cocoon surface.

Species of medicinal leeches (Hirudo medicinalis, H. verbana, and H. sulukii) secrete hard-shelled cocoons.

Punctuated invasion of water, ice, snow and terrestrial ecozones by segmented worms (Oligochaeta: Enchytraeidae: ).

Segmented worms (Annelida) are among the most successful animal inhabitants of extreme environments worldwide. An unusual group of enchytraeid oligochaetes of genus are abundant in the Pacific northwestern region of North America and occupy geographically proximal ecozones ranging from low elevation rainforests and waterways to high altitude glaciers. Along this altitudinal transect, representatives from disparate habitat types were collected and subjected to deep mitochondrial and nuclear phylogenetic analyses.

Trichlorfon-induced haematological and biochemical changes in Cyprinus carpio: ameliorative effect of propolis.

Trichlorfon is among the most commonly used products to treat fish parasites in aquaculture. We investigated the effectiveness of propolis in alleviating the toxicity of trichlorfon on haematological and oxidant/antioxidant parameters in carp Cyprinus carpio. Fish were exposed to sublethal concentrations (11 and 22 mg l-1) of trichlorfon, and propolis (10 mg kg-1 of fish weight) was simultaneously administered.

[A case report: hirudotherapy as a treatment modality in the microsurgery].

Medicinal leeches are known to inject more than 100 bioactive substances in the tissue whilst sucking blood. They are being successfully used for the treatment of diseases and symptoms, especially in plastic surgery. We report the case of a 7-year old boy, who had lost the first phalanx of the middle finger of the right hand after an accident.

Operculum ultrastructure in leech cocoons.

Clitellate annelids (i.e., oligochaetes including leeches) secrete cocoons as part of their normal reproductive cycle.

[Medicinal leeches and hirudotherapy].

Leeches have been used in the treatment of certain diseases since ancient times. There are a few species of medicinal leeches. However, H.

Endohelminth fauna of the marsh frog Rana ridibunda from Lake Hazar, Turkey.

In this study, 236 marsh frogs Rana ridibunda collected from Lake Hazar (Elazig, Turkey) at 15 d intervals between March 2001 and February 2002 were examined for endohelminths; of these, 148 (62.71%) frogs were found to be infected with helminths. In total, 9 helminth species (3 trematodes, 5 nematodes and 1 acanthocephalan) were identified.
