Perpetuation of Borreliae.

Perpetuation of Borreliae. Curr Issues Mol Biol. 2020 Dec 10;42:267-306 Authors: Telford SR, Goethert HK Abstract With one exception (epidemic relapsing fever), borreliae are obligately maintained in nature by ticks. Although some Borrelia spp. may be vertically transmitted to subsequent generations of ticks, most require amplification by a vertebrate host because inheritance is not stable. Enzootic cycles of borreliae have been found globally; those receiving the most attention from researchers are those whose vectors have some degree of anthropophily and, thus, cause zoonoses such as Lyme disease or relapsing fever. To some extent, our views on the synecology of the borreliae has been dominated by an applied focus, viz., analyses that seek to understand the elements of human risk for borreliosis. But, the elements of borrelial perpetuation do not necessarily bear upon risk, nor do our concepts of risk provide the best structure for analyzing perpetuation. We identify the major global themes for the perpetuation of borreliae, and summarize local variations on those themes, focusing on key literature to outline the factors that serve as the basis for the distribution and abundance of borreliae.

After being epidemic in China, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) infection has rapidly spread in many countries as a global pandemic, with the number of affected cases dramatically increasing worldwide on a daily basis. Although the median age of hospitalized patients with confirmed infection is usually more advanced 1, with older age reported to be associated to higher mortality rate 2, physiological adaptations occurring during pregnancy have been claimed to be potentially responsible for a more severe respiratory disease, thus leading to higher rates of maternal and fetal complications 3,4.

On Oct. 1, New York state released an app that can notify you if you’ve come into contact with a person who has tested positive for COVID-19. Called “COVID Alert NY,” the app is one of 10 currently active in states around the U.S. that are based on Google and Apple’s decentralized contact tracing system, which was developed to maintain privacy while also giving health authorities a potentially powerful new tool to clamp down on outbreaks of the virus. “Everybody’s wondering, ‘I was next to this person, I was next to that person,’ but this can actually give you some data,&rdqu...

da HR Abstract The Northeast of Brazil has experienced a triple epidemic, with the simultaneous circulation of dengue virus (DENV), chikungunya virus (CHIKV) and Zika virus (ZIKV), which may have contributed to the observed increase across this region of atypical forms of disease and deaths. In view of this fact, non-congenital neurological disorders related to arboviruses were compared with other etiologies, mortality and survival rates of patients admitted to referral neurology hospitals in Pernambuco State, Northeast Brazil, from 2015 to 2018. Blood and cerebrospinal fluid samples were collected and tested usin...

CONCLUSIONS: The higher frequency of AII sub-assemblage suggests that anthroponotic transmission is more common in Salvador, but that zoonotic transmission pathways are also present and a change in susceptibility to different molecular patterns of Giardia may occur during child growth.

Authors: Brodziński S, Nasierowski T Abstract Borreliosis is a multisystem, bacterial, zoonotic infectious disease with diversified spectrumof symptoms, which may also include psychotic disorders. Clinical picture of the disease is often unspecific, which makes the diagnosis relatively difficult. Uncharacteristic process of borreliosis is a result of complex molecular strategies used by spirochetes to infect, disseminate and survive in host organism. Part I of the article is focused on the current knowledge about pathogenesis of Lyme Borreliosis (LB), especially neuroborreliosis. Additionally, epidemic situation i...
