Changes in hospitals' daily practice due to COVID-19 pandemic may have an impact on antimicrobial resistance (AMR). We aimed assess this possible as captured by the Greek Electronic System for Surveillance of Antimicrobial Resistance (WHONET-Greece). Routine susceptibility data 17,837 Gram-negative and Gram-positive bacterial isolates from blood respiratory specimens hospitalized patients nine tertiary hospitals were used order identify potential differences AMR trends last three years,...
A range of opportunistic pathogens have been associated with dental unit water systems (DUWS), particularly in the biofilms that can line tubing. This study therefore aimed to assess microbiology DUWS and general practices across seven European countries, including United Kingdom (UK), Ireland (IRL), Greece (GR), Spain (ES), Germany (D), Denmark (DK) Netherlands (NL). Water supplied by 51% 237 lines exceeded current American Dental Association recommendations ≤ 200 colony‐forming units (CFU)...
Guaranteeing the safety of swimming pools is a paramount concern worldwide. Robust risk assessment and management practices are crucial for ensuring public safety. A comprehensive understanding chemical equilibrium required in pool water thorough associated physicochemical, microbiological, operational, maintenance risks have become prerequisites effective management. The aim present study was to identify, first time Greece, all possible hazards at different as step scientific-based...
ABSTRACT Water delivered by dental unit water systems (DUWS) in general practices can harbor high numbers of bacteria, including opportunistic pathogens. Biofilms on tubing within DUWS provide a reservoir for microorganisms and should be controlled. This study compared disinfection products their ability to meet the American Dental Association's guideline <200 CFU · ml −1 water. Alpron, BioBlue, Dentosept, Oxygenal, Sanosil, Sterilex Ultra, Ster4Spray were tested ( n = 134) Denmark,...
The use of bacteriophages as potential indicators faecal pollution has recently been studied. correlation the number bacterial and presence three groups bacteriophages, namely somatic coliphages (SOMCPH), F-RNA-specific phages (FRNAPH) Bacteroides fragilis (BFRPH), in raw treated wastewater sludge is presented this study. Raw sewage samples from two treatment plants Athens were collected on a monthly basis, over 2-year period, analysed for total coliforms, Escherichia coli, intestinal...
Bacteria communicate with one another and their host using chemical signalling molecules. This phenomenon is generally described as quorum sensing. A set of primers for PCR detection Salmonella spp. has been designed target the sdiA gene which encodes a signal receptor LuxR family. The product (274 bp) was confirmed by sequencing. number 81 non-Salmonella strains (representing 24 different species) were tested gave negative results, while total 101 serotypes (155 strains) positive presence...
Monophasic Salmonella typhimurium is of increasing importance worldwide. Here we present the available data regarding monophasic S. from 2007 to 2019 in Greece, order assess its public health impact. Surveillance data, on antimicrobial resistance, molecular typing by pulsed-field gel electrophoresis (PFGE), and results investigation outbreaks were analyzed. Overall, 403 cases identified; 329 (81.6%) sporadic 74 (18.4%) related two community 2017. A total 305 isolates tested for resistance...
Recently, multiresistant Salmonella enterica serovar1,4,[5],12:i:-, a monophasic variant of S. Typhimurium(1,4,[5],12:i:1,2) emerged, and is now among the most common serovars isolated from humans in many countries.In Greece, Typhimurium which was recorded for first time human isolates 2007(0.3% total isolates), increased sharply thereafter,and since 2009 third frequent serovar. In present study, 119 1,4,[5],12:i:- strains human, animal food origin, during period between 2006 2011, were...
In spring 2016, Greece reported an outbreak caused by a previously undescribed Salmonella enterica subsp. serotype (antigenic formula 11:z41:e,n,z15) via the Epidemic Intelligence Information System for Food- and Waterborne Diseases Zoonoses (EPIS-FWD), with epidemiological evidence sesame products as presumptive vehicle. Subsequently, Germany, Czech Republic, Luxembourg United Kingdom (UK) infections this novel EPIS-FWD. Concerned countries in collaboration European Centre Disease...
BackgroundThe number of cholera cases reported to the World Health Organization (WHO) in 2022 was more than double that 2021. Nine countries WHO European Region 51 vs five 2021.AimWe aimed confirm
Salmonella spp. is one of the most common foodborne pathogens in humans. Here, we summarize laboratory surveillance data human non-typhoidal salmonellosis Greece for 2003–2020. The total number samples declined over study period (p < 0.001). Of 193 identified serotypes, S. Enteritidis was (52.8%), followed by Typhimurium (11.5%), monophasic 1,4,[5],12:i:- (4.4%), Bovismorbificans (3.4%) and Oranienburg (2.4%). isolation rate 0.001), an increase less serotypes. Monophasic has been among...

Raw anaerobically digested sewage samples from two wastewater treatment plants Athens were collected on a monthly basis, over 2-year period, analyzed for total coliforms, E....
Salmonellosis and shigellosis are mandatorily notifiable diseases in Greece. Underreporting of both has been postulated but there not any national study to quantify it. The objective this was to: a) estimate underreporting hospitalised cases at public Greek hospitals 2011 with a capture-recapture (C-RC) study, b) evaluate the accuracy estimation, c) investigate possible impact specific factors on notification rates, d) community incidence diseases.The mandatory system database National...
SUMMARY Shigellosis is endemic in most developing countries and thus a known risk refugees internally displaced persons. In 2015, massive influx of into Greece, due to the political crisis Middle East, led development appropriate conditions for outbreaks communicable diseases as shigellosis. We present cluster 16 shigellosis cases refugees, detected by implementation syndromic notification system one transit centre Athens, between 20 August 7 October 2015. Both Shigella flexneri ( n = 8) S....
Background: In August 2022, the Hellenic National Public Health Organisation was notified about a gastroenteritis outbreak in town A Southern Greece. Investigations aimed to identify source and implement control measures. Methods: Case definition categories were used 1:3 case–control study. Cases controls interviewed various exposures. Cases’ stool samples cultured on agar plates characterised by serotyping, antimicrobial susceptibility testing Pulse Field Gel Electrophoresis (PFGE)....
We studied the presence of XmnI site and β-globin haplotype in 24 individuals, carriers IVSII-1 G→A β0-globin mutation, whom fourteen had no detectable levels HbF, while ten coming from 5 families, presented HbF ranging 1.7 to 9% total Hb. Of these β-thalassaemia heterozygotes with fetal hemoglobin, 6 were females 4 males median 4.85% 4% respectively, an excess Gγ chains (range Gγ/Aγ: 55/45–70/30). group < 0.1, all cases except one, mutation was found associated polymorphic site. Haplotype...
Water and swab samples were collected from 13 hospitals analyzed for Legionella counts. was detected in eight out of 22 130 water swab-collected samples. A total 72.7% the strains L. pneumophila ser. 1, 22.7% 2-14, 4.5% did not belong to any these groups. AFLP typing 1 generated two distinguishable types. There no significant correlation sample type with recovery. isolation more likely occur cooling towers than system. temperatures 30-40 degrees C seem favor growth. Of 265 serum taken...
Since 2008, veterinary authorities in Greece have implemented national control programmes (NSCPs) targeting S. Enteritidis (SE) and Typhimurium (ST) poultry. We assessed the effect of programs on reported number human isolates. Using monthly data for 2006–2017, we defined two groups (SE, ST) one group with serotypes unrelated to poultry or eggs. For SE also analysed 2006–2015 due a multi-county outbreak 2016. performed an interrupted time series analysis used negative binominal regression...
