1. Occurrence of Hirudinea species in a post urban reach of a Patagonian mountain stream
Temporal (May 2005 to February 2006) and habitat distribution (pools and riffles) of Hirudinea species was analyzed at a post urban reach from Esquel stream (Chubut province, Patagonia, Argentina). Site was located 5.7 km downstream a Waste Treatment Plant. Mean values of nutrients: ammonia, nitrates and soluble reactive phosphate, as well water conductivity

2. Turtle ectoparasites from the Pacific coastal region of Colombia
This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records

3. DIETA, DINÂMICA POPULACIONAL E ECTOPARASITAS DE PHRYNOPS GEOFFROANUS (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) DO BAIXO SÃO FRANCISCO, POÇO REDONDO, SE. / DIET, AND POPULATION DYNAMICS OF PHRYNOPS GEOFFROANUS ECTOPARASITES (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) THE LOWER SAN FRANCISCO, POÇO REDONDO, SE.
Population of P. geoffroanus of Unidade Unidade de Conservação Estadual Monumento Natural Grota do Angico (MNGA) (3740W; 0939S) was studied in relation of their diet, morphometry, growth rates and mass gain, structure and dynamic population and parasites (leeches). The sampling of specimens was performed in monthly campaigns over a year (between January an

4. Caracterização da infecção por tripanossomatídeos (Protozoa: Kinetoplastida) presentes em três espécies de cascudo (Pisces: Loricariidae) do Rio Mogi-Guaçu, SP / Characterization of infection by Tripanossomatídeos (Protozoa: Kinetoplastida) present three species of armored catfish (Pisces: Loricariidae) from Mogi-Guaçu river, SP
Trypanosomes have been reported in several species of fish that inhabit salt and fresh waters. The majority of these protozoan species are described based on morphologic features. The parasites are heteroxenic and are transmitted by leeches. This work aims to characterize the prevalence and density of infection by Trypanosoma sp. present in the blood of thre

5. Development of Hepatozoon caimani (Carini, 1909) Pessôa, De Biasi & De Souza, 1972 in the Caiman Caiman c. crocodilus, the frog Rana catesbeiana and the mosquito Culex fatigans
The sporogony of Hepatozoon caimani has been studied, by light microscopy, in the mosquito Culex fatigans fed on specimens of the caiman Caiman c. crocodilus showing gametocytes in their peripheral blood. Sporonts iniciate development in the space between the epithelium of the insect gut and the elastic membrane covering the haemocoele surface of the stomach

6. Aeromonas hydrophila infection associated with the use of medicinal leeches.
The use of medicinal leeches (Hiruda medicinalis) is becoming more common after plastic surgery to control venous congestion of skin grafts. We describe a patient with Aeromonas hydrophila infection whose graft was treated with medicinal leeches. The infection required systemic antibiotic therapy. A. hydrophila is the predominant bacterial flora in the gut o

7. Use of leeches in a case of severe periorbital haematoma.
A case of severe penetrating eye injury and resulting periorbital haematoma is described. Leeches applied to the eyelids enabled examination of the globe to be carried out and improved the surgical approach. Leeches provide a speedy and efficient means of reducing a periorbital haematoma.

8. Novel Clade of Rickettsia spp. from Leeches
Intracellular rickettsia-like structures were found in the tissues of a glossiphoniid leech, Torix tagoi, by transmission electron microscopy. Diagnostic PCR analysis using specific primers suggested that of the nine glossiphoniid species examined, two species, T. tagoi and Hemicrepsis marginata, harbored bacteria of the genus Rickettsia. A 1.5-kb eubacteria

9. Endosymbiotic Bacteria in the Esophageal Organ of Glossiphoniid Leeches
We characterized the intracellular symbiotic bacteria of the hematophagous glossiphoniid leeches Placobdelloides siamensis and a Parabdella sp. These leeches have a specialized structure called an “esophageal organ,” the cells of which harbor bacterial symbionts. From the esophageal organ of each species, a 1.5-kb eubacterial 16S rRNA gene segment was am
