A 12-year survey of methicillin-resistant Staphylococcus aureus infections in Greece: ST80-IV epidemic?
(2014)Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of both healthcare-associated MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) infections. Severe MRSA infections have been associated with the ... -
Acquired carbapenemases in Gram-negative bacterial pathogens: detection and surveillance issues
(2010)Acquired carbapenemases are emerging resistance determinants in Gram-negative pathogens, including Enterobacteriaceae, Pseudomonas aeruginosa and other Gram-negative non-fermenters. A consistent number of acquired ... -
Activity of Oxacillin versus That of Vancomycin against Oxacillin-Susceptible mecA-Positive Staphylococcus aureus Clinical Isolates Evaluated by Population Analyses, Time-Kill Assays, and a Murine Thigh Infection Model
(2012)We compared the activity of dicloxacillin with that of vancomycin against 15 oxacillin-susceptible, methicillin-resistant Staphylococcus aureus (OS-MRSA) clinical isolates. By population analyses, we found that 6 OS-MRSA ... -
Activity of tigecycline alone and in combination with colistin and meropenem against Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae strains by time-kill assay
(2011)Antibiotic combinations including tigecycline have not been studied against Klebsiella pneumoniae carbapenemase (KPC)-producing pathogens. Tigecycline alone and combined with colistin and meropenem was tested against eight ... -
Activity of Tigecycline in Combination with Colistin, Meropenem, Rifampin, or Gentamicin against KPC-Producing Enterobacteriaceae in a Murine Thigh Infection Model
(2013)Limited antimicrobials remain active for treating severe infections due to KPC-producing pathogens, and optimal regimens have not been established. In murine thigh infections caused by nine KPC-producing clinical strains ... -
Airborne microeukaryote colonists in experimental water containers: diversity, succession, life histories and established food webs
(2011)Airborne freshwater and marine microeukaryotes in the city of Thessaloniki, situated in Thermaikos Bay, Greece, were examined as sources of colonization of experimental water containers during the period autumn 2007 to ... -
Analysis of seawater microbiological quality data in Greece from 1997 to 2006: association of risk factors with bacterial indicators
(2009)This study deals with the examination of quality of seawater bathing areas in Greece over a 10-year period and identifies risk factors for high bacteria indicator organism concentrations. Qualitative descriptive analysis ... -
The antimicrobial effect of oregano essential oil, nisin and their combination against Salmonella Enteritidis in minced sheep meat during refrigerated storage
(2010)The antimicrobial effect of oregano essential oil (EO) at 0.6 or 0.9%, nisin at 500 or 1000 IU/g, and their combination against Salmonella Enteritidis was studied in minced sheep meat during storage at 4 degrees or 10 ... -
The antimicrobial effect of thyme essential oil, nisin, and their combination against Listeria monocytogenes in minced beef during refrigerated storage
(2008)The antimicrobial effect of thyme essential oil (EO) at 0.3%, 0.6%, or 0.9%, nisin at 500 or 1000 IU/g, and their combination against Listeria monocytogenes was examined in both tryptic soy broth (TSB) and minced beef meat. ... -
Antimicrobial susceptibility and genetic relatedness of Salmonella enterica subsp enterica serovar Mbandaka strains, isolated from a swine finishing farm in Greece
(2008)The current study investigated the antimicrobial susceptibility of Salmonella enterica subsp. enterica serovar Mbandaka ( Salmonella Mbandaka) isolated from finishing swines in Greece. Pulsed-field gel electrophoresis ... -
Antimicrobial susceptibility of Neisseria gonorrhoeae in Greece: data for the years 1994-2004
(2006)Objectives: Surveillance data concerning antimicrobial susceptibilities of Neisseria gonorrhoeae isolated in Greece during the 11 year period 1994-2004 are presented. Methods: Antimicrobial susceptibilities of all gonococcal ... -
Apparent richness and community composition of Bacteria and Archaea in geothermal springs
(2009)The archaeal and bacterial 16S rRNA gene diversities of the Polihnitos (89 degrees C), Edipsos (81.8 degrees C), Thermopiles (38.9 degrees C), Eleftheres (41.2 degrees C) and Lagadas (35.2 degrees C) geothermal springs in ... -
Application of rpoB sequence similarity analysis, REP-PCR and BOX-PCR for the differentiation of species within the genus Geobacillus
(2008)Aim: To investigate the applicability of rpoB gene, which encodes the beta subunit of RNA polymerase, to be used as an alternative to 16S rRNA for sequence similarity analysis in the thermophilic genus Geobacillus. Rapid ... -
Association of biofilm formation and methicillin-resistance with accessory gene regulator (agr) loci in Greek Staphylococcus aureus clones
(2009)Pathogenicity of Staphylococcus aureus is coordinated by the accessory gene regulator (agr) system. Previous studies suggested that agr Group 11 methicillin-resistant S. aureus (MRSA), a polymorphism that has been associated ... -
Azithromycin reduces the viability of human bronchial smooth muscle cells
(2010)The macrolide antibiotic azithromycin has an antiproliferative and autophagic effect on rabbit tracheal smooth muscle cells (SMCs). The purpose of this study is to investigate the effect of azithromycin on human bronchial ... -
Bacterial and archaeal phylotypes associated with distinct mineralogical layers of a white smoker spire from a deep-sea hydrothermal vent site (9 degrees N, East Pacific Rise)
(2006)A diffusely venting chimney spire from the East Pacific Rise (9 degrees N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition ... -
Bacterial live vaccines with graded level of attenuation achieved by antibiotic resistance mutations: transduction experiments on the functional unit of resistance, attenuation and further accompanying markers
(1998)At least 10% of spontaneous chromosomal antibiotic resistant mutants of bacteria express a strain-dependent graded reduction of virulence; this correlates linearly with a prolonged generation time. Occasionally, these ... -
Benthic protists and fungi of Mediterranean deep hypsersaline anoxic basin redoxcline sediments
(2014)Some of the most extreme marine habitats known are the Mediterranean deep hypersaline anoxic basins (DHABs; water depth 3500 m). Brines of DHABs are nearly saturated with salt, leading many to suspect they are uninhabitable ...
