The identification of the Tick Borne Relapsing Fever (TBRF) agent in Israel and the Palestinian Authority relies on the morphology and the association of Borrelia persica with its vector Ornithodoros tholozani. Molecular based data on B. persica are very scarce as the organism is still
The vole agent described by Baker in 1946 was studied as an example of a bacterium that has been mistakenly regarded a rickettsia. Unlike rickettsiae, the vole agent killed chicken embryos with great irregularity, multipled primarily at the surface of avian or mammalian cells and not
Several phosphonylmethoxyalkylpurine and -pyrimidine derivatives related to (S)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine [(S)-HPMPA] and 9-(2-phosphonylmethoxyethyl)adenine (PMEA) were evaluated as inhibitors of African swine fever virus (ASFV) replication in Vero cells. (S)-HPMPA has
We aimed to determine the frequency of mutations, carrier rates and the association of rare mutations with Familial Mediterranean Fever (FMF) symptoms. There is a need to evaluate as many different populations as possible in order to determine either specific rare mutations or a range of
BACKGROUND
Familial Mediterranean Fever (FMF), characterized by recurrent fever and inflammation of serous membranes, is an autosomal recessive disease caused by mutations in the Mediterranean fever (MEFV) gene. Around 296 mutations have been reported to date.
METHODS
Two two-generation Turkish
Eight strains of spotted fever group rickettsiae were studied to gain insight into the extent of variation of their properties. Two standard strains of Rickettsia rickettsii and one strain of Rickettsia conorii were included among the eight for comparison. The molar percentage of guanine plus
BACKGROUND
We created a live, attenuated, oral Shigella vaccine by constructing a lineage of guanine auxotrophs and conducted a double-blind, placebo-controlled trial to ascertain (1) the attenuation profile of Delta guaBA Shigella flexneri 2a, which harbors deletions in the guanine nucleotide
Eight different compounds, all nucleoside analogues, could presently be considered as potential drug candidates for the treatment of Ebola virus (EBOV) and/or other hemorrhagic fever virus (HFV) infections. They can be considered as either (i) adenine analogues (3-deazaneplanocin A, galidesivir,
Tumor necrosis factor receptor-associated periodic syndrome (TRAPS), an autosomal disease belonging to human autoinflammatory syndromes, is caused by mutations in Tumor Necrosis Factor Receptor Superfamily Member 1A (TNFRSF1A) gene. Trübenbach and colleagues described a patient with two
Nucleocapsid protein (N) is an essential RNA binding protein in many RNA viruses. During replication, N protein encapsidates viral genomic and antigenomic RNA, but not viral mRNA or other cellular RNAs. To discriminate between different species of RNA in a host cell, it is likely that N interacts
There is evidence for the occurrence of psychopathological symptoms in the adult form of myotonic dystrophy such as disturbance of concentration and memory, chronic depression, disturbed social behaviour, mental retardation, and hypersomnia. In this report we present a patient suffering from
In previous experiments on growth and aging in the yellow-fever mosquito, Aedes aegypti, a low mol. wt. (500000) DNA species was found in the supernatant fraction after ultracentrifugation of homogenates of rapidly-growing larvae. This DNA species, "sDNA", constituted 30-40% of total DNA in
Composites consisting of ss- and ds-DNA strands and polyacrylamide (PAM) hydrogel have been synthesized. DNA was entrapped non-covalently. The obtained DNA biomaterial exhibited a strong increase in guanine and adenine anodic currents when temperature reached the physiological level. This increase
OBJECTIVE
To review our previous studies regarding alterations in gene expression in HSV-1 latently infected mouse trigeminal ganglia (TGs) following treatment with immunosuppressants and hyperthermia.
METHODS
Uninfected and HSV-1 latently infected mice were treated with immunosuppressants or heat
Genome sequencing projects on two relapsing fever spirochetes, Borrelia hermsii and Borrelia turicatae, revealed differences in genes involved in purine metabolism and salvage compared to those in the Lyme disease spirochete Borrelia burgdorferi. The relapsing fever spirochetes contained six open
