[VLP vaccines and effects of HIV-1 Env protein modifications on their antigenic properties].

An ideal protective HIV-1 vaccine can elicit broadly neutralizing antibodies, capable of preventing HIV transmission. The strategies of designing vaccines include generation of soluble recombinant proteins which mimic the native Env complex and are able to enhance the immunogenicity of gp120. Recent data indicate that the cytoplasmic tail (CT) of the Env protein has multiple functions, which can affect the early steps of infection, as well as viral assembly and antigenic properties.

New polyprenyl phosphate based preparation Fortepren(®) as promising cytokine regulationg antiviral remedy.

Fortepren(®), a product of the phosphorylation of polyprenols from fir needles (with sodium polyprenyl phosphate being the main active ingredient), belongs to the class of antiviral drugs with immunomodulating activity. Fortepren(®) may be used as the drug of choice in the treatment of herpes diseases. It was shown that treatment with Fortepren(®) of patients with a chronic recurrent herpes infection after acute phase termination with acyclovir decreased the recurrence rate, as well as the severity of local symptoms.

[Description of a case of severe Q fever].

The paper considers a rare clinical case of severe Q fever in a young man with no compromised premorbid background. It describes and analyzes clinical manifestations and laboratory findings with consideration for the current data available in the literature. The issues of the differential diagnosis, laboratory diagnosis, and treatment of Q fever are discussed.

[Clinical and immunological comparisons of therapeutic regimens for corneal infiltrates secondary to adenoviral keratoconjunctivitis].

Unlabelled: The problem with post-adenoviral corneal infiltrates is that they cause a significant and persistent decrease in visual function, while corticosteroids in monotherapy bring only temporary improvement.

Aim: to perform a comparative evaluation of topical corticosteroids and 0.05% cyclosporine A efficacy in the treatment of post-adenoviral corneal infiltrates on the basis of clinical presentation and local cytokine status.

The Variability of the Order Burkholderiales Representatives in the Healthcare Units.

Background And Aim: The order Burkholderiales became more abundant in the healthcare units since the late 1970s; it is especially dangerous for intensive care unit patients and patients with chronic lung diseases. The goal of this investigation was to reveal the real variability of the order Burkholderiales representatives and to estimate their phylogenetic relationships.

Methods: 16S rDNA and genes of the Burkholderia cenocepacia complex (Bcc) Multi Locus Sequence Typing (MLST) scheme were used for the bacteria detection.

Historical Outbreaks of Simian Hemorrhagic Fever in Captive Macaques Were Caused by Distinct Arteriviruses.

Simian hemorrhagic fever (SHF) is lethal for macaques. Based on clinical presentation and serological diagnosis, all reported SHF outbreaks were thought to be caused by different strains of the same virus, simian hemorrhagic fever virus (SHFV; Arteriviridae). Here we show that the SHF outbreaks in Sukhumi in 1964 and in Alamogordo in 1989 were caused not by SHFV but by two novel divergent arteriviruses.
