Detection of enteroviruses in clinical samples of patients with aseptic meningitis by rapid antigen detection assay.

Introduction: Human enteroviruses represent the most common etiological agents of aseptic meningitis. Rapid diagnosis of aseptic meningitis affects the management of patients.

Objective: The aim of this work was to assess the efficacy of rapid antigen detection (RAD) assay for the confirmation of human enteroviruses in comparison to that of the conventional cell culture (CCC), and to identify the serotypes associated with aseptic meningitis cases in the Autonomous Province of Vojvodina.

[Up-to-date knowledge of West Nile virus infection].

Unlabelled: VIRUS: West Nile virus is a single-stranded RNA virus of the family Flaviviridae, genus Flavivirus.

Epidemiology: West Nile virus is maintained in the cycle involving culicine mosquitoes and birds. Humans typically acquire West Nile infection through a bite from infected adult mosquito.

[Chlamydia trachomatis in women].

The authors present results of a planned prospective study of infections with Chlamydia trachomatis in women. Direct immunofluorescence test (DIF) for proving Chlamydia trachomatis antigens in endocervical smear (by means of monoclonal antibodies), ELISA test for proving IgG antibodies against Chlamydia trachomatis in sera and RVK method for proving antibodies against group Chlamydia-antigen were applied to test 288 women (aged 19-67), previously thoroughly anamnestically and clinically examined Chlamydia trachomatis infection was found in 29.51% of the cases, equally distributed in all age groups.

Significance of screening tests in diagnosis of infectious mononucleosis.

The investigation included 91 patients in who an acute or previous EBV infection was established by ELISA test. All patients were also subjected to the Paul-Bunnell-Davidsohn test, while 20 patients were tested by the rapid screening test Clearview IM. The diagnosis of acute infective mononucleosis was in 61 patients (67%) confirmed by the Elisa test, and in 12 patients (19.

[Virusology at the begining of the XXI century].

Viral injections are the most common human diseases (especiaily acute respiratory infections, mostly in children and young adults). The current studies show that viral infections can cause not only acute, but persistent viral diseases as well. A certain number of viruses are able to incorporate their nucleic acid into the genome of the host-cell, leading to rearrangement of the cell genes and formation of malignant tumors.

[Virology today and tomorrow].

Virus infections are the most common human diseases, particularly acute respiratory infections (mostly in children and young adults). Virus infections of the upper respiratory tract in children are proved in 77.4%, viral bronchitis in 58.

[The frequency of human parvovirus B19 infections in Vojvodina].

Introduction: Human parvovirus B19 is found worldwide. It causes various infections, including fifth disease (erythema infectiosum) in small children, acute arthropathy in adults, transient aplastic crisis and chronic anemia in immunocompromised patients and even fetal infection, which may result in intrauterine fetal death or fetal hydrops. Many of these manifestations of B19 infection are caused by infection of erythroid precursor cells in bone marrow.

[Avian influenza viruses--new causative agents of human infections].

Introduction: Influenza A viruses can infect humans, some mammals and especially birds. Subtypes of human influenza A viruses: A(H1N1), A(H2N2) and A(H3N2) have caused pandemics. Avian influenza viruses vary owing to their 15 hemagglutinins (H) and 9 neuraminidases (N).
