Ticks are the most common arthropod vector, after mosquitoes, and are capable of transmitting the greatest variety of pathogens. For both humans and animals, the worldwide emergence or re-emergence of tick-borne disease is becoming increasingly problematic. Despite being such an important issue, our knowledge of pathogen transmission by ticks is incomplete. Several recent studies, reviewed here...
Seasonal epizootics of vector-borne pathogens infecting multiple species are ecologically complex and difficult to forecast. Pathogen transmission potential within the host community is determined by the relative abilities of host species to maintain and transmit the pathogen and by ecological factors influencing contact rates between hosts and vectors. Increasing evidence of strong feeding pre...
The spleen is one of the major immunological sites for maintaining blood homeostasis. Previous studies showed that heterogeneous splenic macrophage populations contribute in complimentary ways to control blood-borne infections and induce effective immune responses. Marginal metallophilic macrophages (MMMΦs) and marginal zone macrophages (MZMΦs) are cells with great ability to internalize blood-...
Arthropod-borne apicomplexan pathogens that cause asymptomatic persistent infections present a significant challenge due to their life-long transmission potential. Although anti-microbials have been used to ameliorate acute disease in animals and humans, chemotherapeutic efficacy for apicomplexan pathogen elimination from a persistently infected host and removal of transmission risk is largely ...
background and objective: there is a concern on safety of human fresh frozen plasma (ffp) as it is a source of some medicinal products. the possibility of transmission of blood-borne are reported often due to emerging viruses. there are some pathogen reduction technologies (prt) to inactivate viruses. methylene blue (mb) based method is one of them. the aim of this study was to examine new desi...
background: exposure to blood-borne pathogens from needle-stick and sharp injuries continues to pose a significant risk to health care workers. these events are of concern because of the risk to transmit blood-borne diseases such as hepatitis b virus, hepatitis c virus, and the human immunodeficiency virus. objective: to benchmark different risk factors associated with needle-stick incidents am...
conclusions upon our results, tattooed people even with a small size of tattoo on the body are more at risk for hcv, hbv, and hiv infection. results among the 63 patients with tattoos (21% female, 79% male, age range:16 to 79-years-old), four patients (6.3%) tested positive for hbsag and pcr-hbv, seven patients (11%) tested positive for hcv, and five (7.9%) tested positive for hiv. the last gro...
introduction: prevention and control of cross infections for the personnel of dental offices and clinics are a critical issue in dental practice. in this study, a standardized questionnaire was developed to assess the knowledge, attitude and practice of the oral health-care workers in tehran university dental school regarding the blood-transmitted diseases and its validity and reliability were ...
