In order to inventory the metazoan endoparasites of Serrasalmus marginatus, 91 specimens were examined. They were captured in the Negro River in Pantanal wetland, State of Mato Grosso do Sul, Central-Western Brazil, from October 2007 to August 2008. Parasites of six taxa were recovered: Procamallanus (Spirocamallanus) inopinatus, Contracaecum sp. (Nematoda), metacercarial type Diplostomulum (Di...

background: ticks are the main vectors for transmission of different pathogens to human and animals. this survey was performed to find out distribution of ticks, which infested the domestic ruminants in yazd province, central iran during year 2008-2009. methods: a total number of 30 villages from both mountainous (20%) and plateau (80%) regions of the province were selected randomly. ticks were...

The saliva of Rhynocoris marginatus consists of amylase, invertase, trehalase, protease, acid phosphatase, alkaline phosphatase, phospholipase, lipase, trypsin, hyaluronidase, and esterase. All enzyme activities were significantly higher in the saliva of female R. marginatus when compared to the saliva of male individuals. The saliva was analyzed by tricine SDS/PAGE, sephadex column chromatogra...

The investigations concerning the spirochaetes Borrelia burgdorferi sensu lato were conducted in 169 Ixodes ricinus female ticks (141 collected from roe deer and 28 from red deer) as well as in 11 Dermacentor reticulatus female ticks from deer shot in the South-East of Poland. Moreover, a single female Dermacentor reticulatus from a dog and 9 collected from plants were examined. DNA was isolate...

Fragile transmission cycles of tick-borne encephalitis virus may be disrupted by predicted climate change. Rickettsia aeschlimannii in Hyalomma marginatum Ticks, Germany To the Editor: Rickettsia spp. of the spotted fever group cause worldwide emerging human infections known as tick-borne rickettsioses (1). Data on the occurrence and prevalence of Rickettsia in Germany are still limited (2). Si...

Herbivory is a fundamental process determining reef resilience, and while algal farming damselfishes can help shape benthic assemblages, an understanding of their contribution to areas outside of defended territories is relatively unexplored. Here, we demonstrate how the farming damselfish Stegastes marginatus plays a dual role in benthic structuring by 1) contributing to persistence of the inv...
