The occurrence of Listeria monocytogenes in marine fish and market areas was investigated. Two hundred eighty-eight samples (123 environmental samples—siphons, knives, cutting boards, floor, sinks, water, ice—and 165 samples) were examined. Twenty-four isolates characterized as (five from (4.0%) 19 (11.5%)). strains further according to their antibiotic resistance, pathogenicity, biofilm formation ability. They molecularly serotyped IIc (n = 22) IVb 2) possessed all the virulence genes...
A serosurvey of IgG antibodies against severe acute respiratory coronavirus 2 (SARS-CoV-2) was performed during March and April 2020. Among 6,586 leftover sera, 24 (0.36%) were positive, with higher prevalence in females, older individuals residents large urban areas. Seroprevalence estimated at 0.02% 0.25%, respectively, April, infection fatality rate 2.66% 0.54%. Our findings confirm low COVID-19 incidence Greece possibly the effectiveness early measures.
The emergence of the COVID-19 pandemic has led to significant progress in field wastewater-based surveillance (WBS) respiratory pathogens and highlighted its potential for a wider application public health surveillance. This study aimed evaluate whether monitoring syncytial virus (RSV) wastewater can provide comprehensive picture disease transmission at community level. was conducted Larissa (Central Greece) between October 2022 January 2023. Forty-six samples were collected from inlet...
Manouri is a Greek whey cheese, with Protected Denomination of Origin recognition, produced by heating the cheese and added milk and/or cream at high temperatures (88–90 °C) to form coagulum. High-heat treatment results in inactivation any indigenous microorganisms from raw materials. However, moisture, fat pH make it favorable medium for growth microbial contamination. The objective this study was investigate application commercial protective culture (CPC) on profile during storage. Three...
An increased number of hepatitis A cases among refugees, asylum seekers and migrants residing in hosting facilities Greece were recorded between April December 2016. In total, 177 laboratory-confirmed symptomatic reported; these, 149 (84%) occurred camps mostly Syrian children under 15 years. All reported symptom onset after their entry into the country. Public health interventions focused on hygiene measures vaccination.
In March 2012, there was an unusual increase of gastroenteritis cases in a district with 37,264 inhabitants central Greece. It estimated that more than 3600 people developed symptoms. A 1:1 case-control study showed consumption tap water risk factor for acquiring infection [odds ratio (OR) 2.18, 95% confidence interval (CI) 1.11-4.28]. Descriptive data, low incidence adjacent areas different supply systems, and water-quality data further supported the hypothesis waterborne outbreak....
The estimation of anti-SARS-CoV-2 IgG antibodies is possibly the best approach to accurately establish number infected individuals and seroprevalence COVID-19 within a population. Thus, several commercial immunoassays have recently been developed. purpose our study was assess performance five commonly used in Greece (3 ELISA, namely Euroimmun SARS-CoV-2, GA GENERIC SARS-CoV-2 Vircell COVID-19; 2 chemiluminescent, ABBOTT ROCHE Elecsys Anti-SARS-CoV-2 test) for detection antibodies. Sera...
The aim of this study is to explore the dispersion, clonality, and virulence Legionella pneumophila serogroups 2 14 in Greek environment. Eighty L. serogroup strains isolated from water distribution systems hotels, hospitals, athletic venues, ferries Greece were tested by monoclonal antibodies (MAbs) for discrimination molecularly amplified fragment length polymorphism (AFLP) genetic diversity. Fifty-six 80 also typed sequence-based typing (SBT) method. Αll further analyzed detection two...
A COVID-19 outbreak occurred among residents of a Roma settlement in Greece (8 April–4 June 2020). The aim this study was to identify factors associated with an increased risk severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and evaluate the effectiveness control measures implemented. Data were analyzed from individuals that tested for SARS-CoV-2 during contact tracing, population screening or hospital visits. RT-PCR used detection oropharyngeal samples. Risk household...
This study aimed to assess the colonization of hotel water systems in central Greece and Corfu by Legionella, investigate association between physicochemical parameters Legionella colonization. Standardized hygiene inspection was conducted 51 hotels, 556 samples were analyzed for spp. Free chlorine concentration, pH, hardness, conductivity, trace metals defined cold samples. The results inspections chemical analyses associated with microbiological using univariate logistic regression...
The aim of our study was to investigate the immunogenicity BNT162b2 vaccination according age and medical status vaccinated individuals. A total 511 individuals were enrolled (median age: 54.0 years, range: 19-105); 509 these (99.6%) received two doses at an interval 21 days. IgG IgA responses evaluated on days 21, 42, 90, 180 after first dose with chemiluminescent microparticle ELISA assays. cell-mediated immune assessed by automated interferon-gamma release assay. We demonstrated positive...
Background: Food safety is a major public health consideration during athletic events. On 27 June 2019, the Hellenic National Public Health Organization was notified of cluster gastroenteritis cases among athletes four 47 teams participating at Panhellenic Handball Championship for children. Methods: A retrospective cohort study members performed. The local authority visited restaurants where common meals took place, amassed information on preparation meals, and collected samples leftovers....
Hepatitis A is a mandatory notifiable disease in Greece. Here, we present the epidemiological data for 2009-2018 and results of outbreak investigations performed, discuss future public health priorities.Overall, 1193 cases were reported; 320 migrants/refugees, 240 Roma, 112 travellers 521 from general population. The median age affected population (37 years) had an increasing trend (from 30.8 years 2009 to 40.5 2018, P < 0.001) was significantly higher than that among Roma migrants (7 8...
After the Elizabethkingia anophelis outbreak in Wisconsin, USA, an active search for detection of microorganism hospital water systems from Central and Northern Greece was performed June to December 2016. In total, 457 samples 11 hospitals were analyzed. spp. detected three collected two hospitals, both which are located Greece. Two isolated strains identified as anophelis. No cases infection reported either during This is first isolation pathogen supply
We describe response measures to an outbreak involving 128 (33.4%) coronavirus disease cases (46.1% asymptomatic) among 383 persons onboard a passenger ship. Multivariate analysis indicated that dining in certain rooms and bar areas, nationality, working department (for crew members), quarantining the ship were significantly associated with infection.
Bacterial communities, microbial populations, and antibiotic resistance of potential pathogens in the water fish (Cyprinus carpio, flesh gut) from different areas (A1, A2 A3—A1 was linked with river water, cattle activity, A3 waters a spring after heavy rains) Lake Karla (Thessaly, Central Greece) were investigated. The isolated bacteria identified using Matrix-assisted laser desorption ionization–time flight mass spectrometry (MALDI-TOF MS) tested for 21 antibiotics. microbiota composition...
