flaviviridae are viruses that cause several diseases including dengue fever, japanese encephalitis, murray valley encephalitis, tick-borne encephalitis, west nile encephalitis, yellow fever and hepatitis c virus infection. members of this family have monopartite, linear, single-stranded rna genomes of positive polarity, 9.6-12.3 kb in length. here, we have analyzed the codon usage of 13 species...
The ubiquity of ticks and their importance in the transmission of pathogens involved in human and livestock diseases are reflected by the growing number of studies focusing on tick ecology and the epidemiology of tick-borne pathogens. Likewise, the involvement of wild birds in dispersing pathogens and their role as reservoir hosts are now well established. However, studies on tick-bird systems ...
Tick-borne relapsing fever is an endemic disease in some parts of Iran. Borellia persica, the most common cause of this disease in Iran, has a wide geographic distribution and is present in Alborz and Zagros mountain chains.Here we report a 16–year-old male patient who presented with two episodes of fever within 15 days. He had a history of few overnight stays in a cave of mountainous area in F...
BACKGROUND AND AIMS Ticks are highly susceptible to global environmental and socio-economical changes. Several tick-borne pathogens have been reported in new geographical regions while new species, strains or genetic variants of tick-borne microorganisms are continually being detected. However, tick-borne pathogens are still poorly understood, and it is estimated that half of all human tick-bor...
Ticks and tick transmitted infectious agents are increasing global public health threats due to abundance, expanding geographic ranges of vectors pathogens, emerging tick-borne agents. Greater understanding tick, host, pathogen interactions will contribute development novel control disease prevention strategies. Tick-borne pathogens adapt in multiple ways very different vertebrate host environm...
Ticks are obligate haematophagous acarines that parasitise every class of vertebrate (including man) and have a worldwide distribution. An increasing awareness of tick-borne diseases among clinicians and scientific researchers has led to the recent description of a number of emerging tick-borne bacterial diseases. Since the identification of Borrelia burgdorferi as the agent of Lyme disease in ...
The tick is a well-known vector for arthropod-borne pathogens, such as tick-borne encephalitis, Lyme disease, Japanese spotted fever and severe fever with thrombocytopenia syndrome. It is therefore important to know the tick population and distribution in our environment and wild animals in order to prevent tick-borne diseases. Here, we report the results of tick surveillance from May to Septem...
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...
During most of the 20th century, the epidemiology of tick-borne rickettsioses could be summarized as the occurrence of a single pathogenic rickettsia on each continent. An element of this paradigm suggested that the many other characterized and noncharacterized rickettsiae isolated from ticks were not pathogenic to humans. In this context, it was considered that relatively few tick-borne ricket...
