background: since alkaloids are nitrogenous compounds, the availability of nitrogen (n) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. objective: this study intended to investigate the nitrogen (n) fertilization and water deficit stress (wds) effects on seed tropane alkaloids elicitation including hyoscyamine (hyo) and scopolamine (sco), and a...

"Candidatus Neoehrlichia mikurensis" (Anaplasmataceae) is an emerging pathogen transmitted by Ixodes ticks. Conventional PCR and the newly developed high-resolution melt PCR were used to detect and discriminate "Candidatus Neoehrlichia mikurensis" and Anaplasma phagocytophilum. Both bacterial species were frequently found in Ixodes ricinus and Ixodes hexagonus but virtually absent from Dermacen...

background: regarding the prevalence of epilepsy in human society and with respect to inefficiency of the usual treatments, finding new strategies and methods for the medical treatment of epileptic patients are essential. henbane seed has been used in iranian traditional medicine as an anti-convulsion herb. with this regard the present study was carried out to consider the anti-convulsive effec...

The distribution and prevalence of zoonotic pathogens infecting ixodid ticks in Western Europe have been extensively examined. However, data on tick-borne Eastern Europe, particularly Ukraine are scarce. objective the current study was, therefore, to investigate Anaplasma phagocytophilum, Anaplasmataceae, Rickettsia spp., Babesia Bartonella Borrelia burgdorferi sensu lato engorged questing coll...

The south of Western Siberia traditionally belongs to the regions with unfavorable epidemiological situation for tick-transmitted infections. In Novosibirsk and its suburbs, approximately 20 thousand people annually seek medical care after tick bites. purpose this work was determine human-attacking species composition in territory suburbs by identifying nucleotide sequence mitochondrial gene cy...

This paper reports a 17-year seroepidemiological surveillance study of Borrelia burgdorferi infection, performed with the aim of improving our knowledge of the epidemiology of this pathogen. Serum samples (1,179) from patients (623, stratified with respect to age, sex, season, area of residence and occupation) bitten by ticks in two regions of northern Spain were IFA-tested for B. burgdorferi a...

This study aimed to identify the incrusting and sedentary animals associated with the hull of a tugboat active in the ports of Pernambuco and later loaned to the port of Natal, Rio Grande do Norte. Thus, areas with dense biofouling were scraped and the species then classified in terms of their bioinvasive status for the Brazilian coast. Six were native to Brazil, two were cryptogenic and 16 non...

The focus of this work is to explore the use of the netted whelk, Nassarius reticulatus (L.), as an indicator of mercury (Hg) contamination, by assessing the concentration of Hg in the sediments and in the whelk along the entire Portuguese coast. Total Hg concentrations ranged from below the detection limit (0.01 ng absolute mercury) up to 0.87 mg kg(-1) dry weight (dwt) in sediments and betwee...
