Human calicivuruses and an immune response

Abstract

The review deals with calicivirus infection that has long been known in animals, but also just recently disclosed in humans. Human caliciviruses induce outbreaks of acute gastroenteritis in all countries of the world, which makes this immunobiological research very actual. The history of this discovery, evolution of caliciviruses, the host resistance and immune response mechanisms are described in this review.

Impact of asymptomatic herpesvirus infection on the female reproductive system

Abstract

The fact that asymptomatic and subclinical isolation of the virus in the infected, which is, according to the data of different authors, noted in 50-90% of cases, presents the highest hazard to the spread of herpesvirus infection may be now considered to be proven. The development of assisted reproductive technologies have led to the active study of the factor of male infertility in marriage, including that of the negative impact of asymptomatic infection caused by herpes simplex virus (HSV) on spermatogenesis. At the same time, there is no consent of opinion as to the implication of asymptomatic HSV in female reproductive dysfunction. The presented review attempts to analyze the data available in the literature on the detection of HSV in the reproductive organs of a woman without a history of the clinical episodes of the disease and to assess a role of HSV infection in the development of female infertility.

Herd immunity against poliomyelitis in children in the Moscow Region

Abstract

Herd immunity against poliomyelitis was studied in 1391 children and adolescents from 10 towns of the Moscow Region. It was ascertained that the values of herd immunity against poliomyelitis virus type 1 were high everywhere and those of herd immunity against poliomyelitis virus type 2 were high and very high in 9 towns and below the WHO minimum levels (80%). The values of herd immunity against poliomyelitis virus type 3; they were lower than the required minimum in 2 towns and very low in 2 other towns arouse alarm. The study of strain-specific antibodies to vaccine-derived and wild polioviruses has demonstrated that wild poliomyelitis viruses have not circulated in the areas of the examinees in the past decade.

Herpesvirus type 8 and its implication in human pathology

Abstract

Herpesvirus type 8 or Kaposi's sarcoma-associated virus has been recently discovered and it is an etiologic agent of several known diseases. It has common features that link it with other representatives of the family Herpesviridae: similar structural elements and genomic organization, and the common mechanisms of replication. Nevertheless, this virus has a number of unique features that make it an interesting matter for investigations and currently central in modern medicine and biology. This overview is to draw attention to this representative of herpesviruses and to outline some epidemiological, pathogenetic, and molecular aspects of this problem.

Genetic diversity of human caliciviruses detected in schoolchildren with gastroenteritis in Nizhni Novgorod

Abstract

A total of 2312 children admitted to the Nizhni Novgorod infectious disease hospitals for diagnosed acute gastroenteritis were examined using the RT-PCR. The detection rate of human caliciviruses was found to be 6.5% (range 1.2 to11.2%). The population of calicivuruses presented with noroviruses genogroups I (16%) and II (81%), and sapoviruses (3%). Noroviruses genogroup II included genotypes GII.2 and GII.4 with a preponderance of the variant CII.4-2006b. The detected sapoviruses were clustered with sapoviruses GI.1, GI.2, and GII.1 by phylogenetic analysis.

Identification of human pathogenic variola and monkeypox viruses by real-time polymerase chain reaction

Abstract

A kit of specific oligonucleotide primers and hybridization probes has been proposed to detect orthopoxviruses (OPV) and to discriminate human pathogenic viruses, such as variola virus and monkey virus by real-time polymerase chain reaction (PCR). For real-time PCR, the following pairs of fluorophore and a fluorescence quencher were used: TAMRA-BHQ2 for genus-specific probes and FAM-BHQ1 for species-specific ones (variola virus, monkeypox virus, ectomelia virus). The specificity of this assay was tested on 38 strains of 6 OPV species and it was 100%.

Localization of human cytomegalovirus immediate-early protein IE-1 pp72 in the juxtanuclear inclusion at the late stage of infection

Abstract

Immediate-early protein IE-1 pp72 is one of the most abundant proteins at the early stage of human cytomegalovirus infection and has a number of intranuclear activities. This paper gives immunocytochemical and ultrastructural data on IE-1 pp72 accumulation in the juxtanuclear inclusion at the late stage of low-multiplicity infection. Detection of a new localization site infers that this protein may participate in the final steps of virus morphogenesis and play a functional role in the pathogenesis of cytomegalovirus infection.

Chemotherapy for Bolivian hemorrhagic fever in experimentally infected guinea pigs

Abstract

The efficacy of the antiviral agents nucleoside analogues manufactured in Russia and foreign countries against Bolivian hemorrhagic fever in the treatment and rapid prevention regimens was studied in guinea pigs. In rapid prevention and treatment of guinea pigs, the intraperitoneal injection of 1/10 of the equivalent dose of vero-ribavirin for this animal species was ascertained to protect 70% of the animals infected with Machupo virus strain Carvallo in doses 8 and 10 LD50.
