identification of host blood meal in haematophagous arthropods is an important element in their rule in transmission of vector borne diseases. the effects of post ingestion and physical conditions that killed mosquitoes are stored on the success of detecting blood meal dna of anopheles stephensi and culex quinquefasiatus was investigated by polymerase chain reaction (pcr) amplification at the h...

we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and  fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...

background and objectives: food poisoning has been always a major concern in health system of every community and cream-filled products are one of the most widespread food poisoning causes in humans. in present study, we examined the preservative effect of the cinnamon oil in cream-filled cakes. methods: antimicrobial activity of cinnamomum verum j. presl (cinnamon) bark essential oil was examin...

abstract human blood and blood products is the source of a wide range of medicinal products used for the treatment and prevention of a variety of injuries and disease. despite stringent routine measures and filters employed, residual pathogen infectivity remains an important challenge in the field of blood transfusion. in this article various measures and technologies that can be applied in ord...

background: the risk for transmission of blood-borne viruses (bbvs) such as human immunodeficiency virus (hiv), hepatitis b virus (hbv) and hepatitis c virus (hcv) due to occupational exposure is a major concern in the health care setting. m aterials and methods: this study among 337 health care workers (hcws) accidentally exposed to bbvs was carried out from january 2009 to march 2015. the dat...

Tick-borne spirochetes include borreliae that cause Lyme disease and relapsing fever in humans. They survive in a triangle of parasitic interactions between the spirochete and its vertebrate host, the spirochete and its tick vector, and the host and the tick. Until recently, the significance of vector-host interactions in the transmission of arthropod-borne disease agents has been overlooked. H...

We assessed the risk for human tick-borne encephalitis (TBE), ixodid tick-borne borrelioses, and double infection from 1994 to 1998 in Perm, which has among the highest rates of reported cases in Russia. We studied 3,473 unfed adult Ixodes persulcatus ticks collected from vegetation in natural foci and 62,816 ticks removed from humans. TBE virus and Borrelia may coexist in ticks.
