Analysis of Cultured Gut Microbiota Using MALDI-TOF MS in COVID-19 Patients from Serbia during the Predominance of the SARS-CoV-2 Omicron Variant.

The currently dominant SARS-CoV-2 omicron variant, while causing mild respiratory symptoms, exhibits high transmissibility, drug resistance, and immune evasion. We investigated whether the presence of the SARS-CoV-2 affected the dynamics of fecal microbial composition isolated in culture in moderate COVID-19 patients. Blood, stool, and medical records were collected from 50 patients with confirmed SARS-CoV-2 infection.

Diagnostic value of urine qRT-PCR for the diagnosis of West Nile virus neuroinvasive disease.

Short and low-level viremia and virorachia, antibody cross-reactivity, IgM persistence, and inaccessibility of neutralization test, make laboratory diagnosis of West Nile virus (WNV) infection difficult. Recent investigations imply that WNV is excreted in urine longer and at higher concentrations compared to blood. The detection of WNV nucleic acid in cerebrospinal fluid (CSF), serum, and urine samples collected from 41 patients with suspected WNV neuroinvasive disease, was done by real-time RT-PCR assay.

Human papillomavirus-specific antibody status among unvaccinated subjects in the region of Vojvodina, Serbia.

Objectives: The aim of the study was to evaluate the immune status of young people from the Vojvodina province, Serbia, through the detection of IgG antibodies specific for the L1 protein of HPV types 6, 11, 16, and 18 contained in quadrivalent vaccine.

Methods: The study enrolled 514 healthy persons of both genders, aged between 18 and 30 years. All potential participants were informed about the project's aims by trained interviewers before venous blood collection.

Negative trend in seroprevalence of anti-toxoplasma gondii IgG antibodies among the general population of the province of Vojvodina, Serbia, 2008-2021.

This study aimed to estimate dynamic changes in seroprevalence of Toxoplasma gondii within the general population living in the northern part of the Republic of Serbia (Province of Vojvodina) during a 14-year period. The differences in prevalence of anti-toxoplasma antibodies were analyzed in correlation with age, gender, residential area (rural/urban) and meteorological factors. In this cohort retrospective study, 24,440 subjects between 1 and 88 years old were enrolled.

The prevalence of 30 HPV genotypes detected by EUROArray HPV in cervical samples among unvaccinated women from Vojvodina province, Serbia.

This study evaluates the pre-vaccination prevalence of HPV infection in women from Vojvodina, Serbia, according to age and cytological status. A total of 1,495 women, ranging from 18 to 65 years of age, with different cytological results were enrolled. The HPV genotyping assay was performed using the EUROArray HPV test in order to detect thirty genitally relevant HPV subtypes.

Prevalence of oncogenic Human papillomavirus and genetic diversity in the L1 gene of HPV16 HPV 18 HPV31 and HPV33 found in women from Vojvodina Province Serbia.

The main purpose of this paper is to estimate the pre-vaccination prevalence of 12 hrHPV types among 564 women from Vojvodina province (Serbia). The corrected contingency coefficient (Ccorr) was used to estimate the importance of association of examined HPV types and cytological diagnosis. The highest association with the abnormal cytology was observed for HPV 16 (Ccorr = 0.

West Nile Virus Lineage 2 Associated with Human Case in Republic of Serbia.

A suspicion on West Nile virus (WNV) in Serbia was first reported in 1972 by a seroprevalence study, after which no data were available for four decades. We report full sequence of the isolate obtained for the first time from a human sample in Serbia. The closest clustering was obtained with lineage 2 WNV identified in Greece in 2010.

Risk factors for severe influenza A virus infections in post-2009 pandemic period.

Introduction: Literature data concerning risk factors for severe influenza in post-2009 pandemic period, from low- and middle-income Central and Eastern European countries are very limited.

Objective: The aim of this study was to investigate the risk factors for severe A(H1N1)pdm09 and A(H3N2) influenza during the post-2009 pandemic period.

Methods: During four consecutive seasons of 2010/2011–2013/2014, nasopharyngeal or nasal and pharyngeal swab samples from 153 patients with mild and 147 patients with severe influenza were tested using real-time reverse transcription polymerase chain reaction (real-time RT PCR) assays.

Frequency of twelve carcinogenic human papilloma virus types among women from the South Backa region, Vojvodina, Serbia.

Background/aim: The aim of this study was to determine the presence and age distribution of different oncogenic human papilloma virus (HPV) types in women in the South Backa region and its relationship to Pap results.

Materials And Methods: In a group of 1087 women with normal and abnormal cytology, the commercial HR HPV Real-TM kit (Sacace Biotechnologies, Italy) was used.

Results: Overall, 50.

TICK-BORNE ENCEPHALITIS VIRUS INFECTION IN HUMANS.

Introduction: Tick-borne meningoencephalitis virus is a flavivirus that causes the most important vector-borne central nervous system infection in many countries of Europe and Asia. There are three subtypes of tick-borne encephalitis virus: European, Siberian and the Far-Eastern subtype.

Transmission: In endemic areas, the virus remains in transmissive cycles between Ixodes ticks and small rodents.

Testing for viral material in water of public bathing areas of the Danube during summer, Vojvodina, Serbia, 2014.

From August to September 2014 a water quality study was conducted on five popular public Danube beaches in Vojvodina, Serbia. To assess the safety of Danube water for bathing, physical, chemical, bacteriological tests were performed. While many parameters for monitoring the quality of water are regulated by law, there are neither national nor international legislations addressing the presence of viruses in recreational waters.

Influenza B Viruses in the Population of Province of Vojvodina during the 2012/2013 Season: Differentiation of B/Yamagata and B/Victoria Lineages by Real-time RT-PCR, Antigenic and Phylogenetic Characterization.

Introduction: At present, two phylogenetically distinct influenza B virus lineages, B/Yamagata and B/ Victoria, co-circulate worldwide and can cause significant morbidity and mortality.

Objective: The aim of this study was to determine the prevalences of two influenza B virus lineages in the population of Vojvodina and to identify their antigenic and phylogenetic properties.

Methods: A total of 369 and 334 nasopharyngeal, or nasal/throat swab samples, collected during the 2012/2013 and 2013/2014 seasons, respectively, were tested using specific singleplex influenza A, influenza B, influenza B/Yamagata and influenza B/Victoria real-time reverse transcription polymerase chain reaction (RT-PCR) assays.

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.
