Antimicrobial susceptibility patterns of Campylobacter jejuni strains isolated from hospitalized children in Athens, Greece
Sera from patients with high titers of antibody to streptolysin O react with listeriolysin
Sera of patients with suspected rheumatic fever and elevated titers of antibody to streptolysin O were examined by an immunoblotting technique. All but two serum samples, which yielded relatively low titers, bound to a 60-kilodalton protein in the supernatant from a culture of Listeria monocytogenes, which presumably represents the listeriolysin.</jats:p
Incidence and antimicrobial susceptibilities of genital mycoplasmas in outpatient women with clinical vaginitis in Athens, Greece
Objectives: The incidence and antimicrobial susceptibilities of Ureaplasma urealyticum and Mycoplasma hominis, isolated from vaginal and endocervical swabs collected from 369 outpatient women, were determined. Methods: Isolation, identification and typing of the pathogens were performed by means of conventional methods. The antimicrobial susceptibilities of the genital mycoplasmas were determined with commercially available kits and evaluated according to the CLSI. Results and conclusions: In 65 (47.44%) out of the 137 positive specimens, U. urealyticum was grown as a single pathogen, in 0.72% M. hominis was grown as a single pathogen and in 2.92% both urogenital mycoplasmas were grown. In the remaining specimens (48.90%), there was a mixed growth with other microbes. Of the isolated U. urealyticum strains, 87.4% and 98.2% were susceptible to tetracycline and doxycycline, respectively, 79.2% were susceptible to josamycin, 48.6% were susceptible to clarithromycin and 91.8% were susceptible to pristinamycin, while erythromycin, azithromycin, ciprofloxacin and ofloxacin proved to be inactive against most of the strains. M. hominis isolates were 100% susceptible to tetracycline, doxycycline and pristinamycin, while susceptibilities to the other antimicrobial agents varied mainly in the range of 'intermediate' or 'resistant'. As results originating from similar studies from various countries are very controversial, the simplest way to avoid therapeutic failures would be the implementation of rational treatment regimens based on culture isolation and the in vitro determination of the antimicrobial susceptibility of genital mycoplasmas in each clinical case
Correlation between flagellin A(flaA) genotypes and antimicrobial susceptibility patterns of campylobacter jejuni strains isolated from children with gastroenteritis in Athens, Greece
Background and Objective: Campylobacter jejuni is one of the most common enteric pathogens worldwide. The bacterium is transmitted to humans via contaminated food and water. In the majority of cases the disease is self-limiting, but treatment is indicated in immunocompromised patents, in severe cases with septicemia, and in children. The subtyping of clinical, animal, and food C. jejuni isolates is very important for epidemiological studies. In the present study, 192 Campylobacter jejuni isolates characterized by pulsed-field gel electrophoresis (PFGE) of SmaI digested genomic DNA were further examined with respect to their antimicrobial resistance and their flagellin A (flaA) genotypes in order to disclose any correlation between a certain flaA type and a specific antimicrobial susceptibility pattern. Methods: C. jejuni clinical isolates were collected from infected children up to 14 years of age from five general hospitals in the area of Attica, Greece, during the period 2004-7. C. jejuni strain isolation and identification from stool samples were performed by conventional bacteriological methods. SmaI restriction fragments were prepared as described previously for the PFGE analysis. Antimicrobial susceptibility was tested and interpreted by determination of the minimal inhibitory concentration (MIC) by use of the agar dilution method as described by the Clinical Laboratory Standards Institute. FlaA typing was performed by PCR amplification of the corresponding gene, and the product was digested with DdeI and visualized by agarose gel electrophoresis. Data were analyzed using the software Gene Profiler 1-D Gel Analysis and Data Basing for Windows. Results: A statistically significant correlation between certain flaA genotypes (flaA 17 Greece [GR], flaA 19 GR and flaA 39 GR) and resistance to some antimicrobial agents (ampicillin, amoxicillin/clavulinic acid [co-amoxiclav], erythromycin, nalidixic acid, and ciprofloxacin) was detected in C. jejuni strains isolated from infected children. Conclusions: Further investigations on a molecular basis are warranted in order to clarify whether certain C. jejuni flaA types are associated with specific antimicrobial resistance attributes. © 2009 Adis Data Information BV.

Internal-market orientation: a misconceived aspect of marketing theory
<p><b>Purpose:</b> Although many authors argue that practising marketing internally facilitates the implementation of the market orientation concept, systematic empirical research to explore the validity of the argument remains surprisingly scarce. Hence, the purpose of this paper is to investigate empirically the relationship between market orientation (MO) and internal-market orientation (IMO) as well as their joint effect on customer satisfaction.</p>
<p><b>Design/methodology/approach:</b> The findings ground on data collected from dyads of financial services providers and their customers. The former provided the information pertaining to the company's degree of MO and IMO adoption as well as on perceived employee value, while the latter were asked about perceived customer value, perceived service quality and their satisfaction with their provider. In total 127 dyads are employed in the analysis.</p>
<p><b>Findings:</b> The findings show that MO and IMO are two inter-related concepts, probably falling under the marketing philosophy umbrella. Through MO adoption, customer perceived value and customer perceived quality of the service increase. Through IMO adoption, the company improves the level of employee perceived value, which also results in higher levels of customer perceived service quality. Interestingly enough, IMO adoption is also found to have a direct impact on customer perceived service quality.</p>
<p><b>Research limitations/implications:</b> The major implication from the study is that adopting a market orientation does help improve customer satisfaction but this objective is better served when developing a more holistic view of marketing and trying to simultaneously offer value to other company stakeholders, such as the employees. The major limitation of the study is the focus on services. When it comes to manufactured goods, customers receive significant value from the tangible parts of the product and consequently further investigation is required before any generalization can be made on the basis of the strength of the relationships that this study reveals.</p>
<p><b>Practical implications:</b> The most significant implication for practitioners is the need to strike the right balance between the company's internal and external orientation. To achieve this, companies have to invest in integrating the marketing and the human resource functions, in much the same manner in which they attempt to integrate marketing with other company functions that also influence customers' experiences.</p>
<p><b>Originality/value:</b> This is the first empirical study to investigate the inter-relationship and the joint effect of two well established notions, i.e. that between MO and IMO, and thus offers the required support to normative arguments regarding the need to sustain a balance between the company's external and internal focus.</p>
