BACKGROUND Rhipicephalus sanguineus and Hyalomma marginatum are the most common species in sheep herds in Northeast of Iran. There is preliminary evidence that these species may be the vectors of Babesia ovis in Iran. We carried out two experiments in Mashhad area, Khorasan Razavi Province to determine whether B. ovis could be transovarially transmitted by R. sanguineus and H. marginatum. MET...

One hundred and seventeen scrub hares, Lepus saxatilis, were examined for ixodid ticks in various regions of the Cape Province. They were infested with 18 tick species and the seasonal abundances of the immature stages of Amblyomma hebraeum, Amblyomma marmoreum, Hyalomma marginatum rufipes, Rhipicephalus appendiculatus and Rhipicephalus glabroscutatum and all stages of Rhipicephalus oculatus an...

A total of 784 (626♀, 158♂) Hyalomma marginatum Koch, 1844 ticks collected from humans in Turkey were tested for the presence of spotted fever group rickettsiae using polymerase chain reaction (PCR) targeting the citrate synthase (gltA= 381 bp) and the outer membrane protein A (ompA= 532 bp) genes, followed by sequencing analysis. Of the ticks tested, 39 were infected by Rickettsia aeschlimanni...

BACKGROUND Bupleurum marginatum Wall. ex DC (Apiaceae) is a perennial herb widely used in traditional Chinese and Kampo medicine for the treatment of various infectious diseases. The biological activities of B. marginatum have not been fully investigated. This study aims to investigate the antitrypanosomal, antimicrobial and antiviral activities of methanol (ME) and dichloromethane (DCM) extrac...

BACKGROUND Mosquitoes are the primary vectors of West Nile virus (WNV). Ticks have, however, been suggested to be potential reservoirs of WNV. In order to investigate their role in the spread of the virus, ticks, which had been collected from birds migrating northwards from Africa to Europe, were analyzed for the potential presence of WNV-RNA. METHODS On the Mediterranean islands Capri and An...

The aim of this study was to analyze synanthropic birds as risk factors for introducing ticks and tick-borne pathogens into human settlements, with an emphasis on rickettsiae. Altogether 184 subadult ticks were found on 5846 birds. Tick infestation was most prevalent during the spring. In this sample group the majority of ticks were molecularly identified as Ixodes ricinus, and three individual...

Marine organisms are rich source of structurally new and biologically active metabolites. There have been many reports of macro algae-derived compounds that possess a broad range of biological functions, such as antibiotic, antiviral, antioxidant, antiinflammatory, cytotoxic, and antimitotic activities. Bioactive components have been revealed in many marine algae. Marine algal compounds are pre...

Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is a rare genetic disease that causes recurrent swelling attacks that may affect various body tissues. Angioedematous attacks can be fatal in the case of upper airway edema and are often preceded by prodromal symptoms like erythema marginatum. Initial symptoms usually occur in the first decade of life. We report on manifestation ...
