  Tularemia is a zoonotic disease caused by Francisella tularensis which can be transmitted to humans by tick bites contaminated water handling infected materials and inhalation. The different clinical types are ulceroglandular, glandular, oropharyngeal, oculoglandular, typhoidal and pneumonic tularemia. Streptomycin and tetracycline are commonly used to treat this infection. In this study approched other patients after the suspected tularemia patient attended to Kirikkale University, Faculty of Medicine with the servical mass complaint at January 2010. To find the reservoir for tularemia, laboratory research was carried on the mice suspected to be infected with Francisella tularensis in the town of infection.

  Aim: The aim of the present study was to investigate the survival time of some nosocomial infectious agents on the surface of various covering materials.

Materials and Methods: Four kinds of flooring materials (vinyl and ceramic tile as floor covering material; and laminate and inox sheet as bench covering material) were experimentally contaminated with Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and vancomycin-resistant (VR) Enterococcus faecalis, which were frequently encountered in nosocomial infections. The survival periods of representative agents on the tested flooring materials were detected by culturing from the surfaces.

Results: It was found that the survival periods were shorter for all the tested bacteria on the vinyl surfaces, as compared to the ceramic surfaces; the difference was significant (P < 0.05). On the other hand, all the test bacteria survived shorter on the inox sheet than on the laminate surfaces (P < 0.05). On all of the 4 covering materials tested gram-positive bacteria were found to survive longer than the gram-negative ones.

Conclusions: It was concluded that vinyl as flooring material and inox sheet as surface material for benches and laboratory tables may be preferred in order to reduce bacterial colonisation in the hospital environment.

  Until recently, the tuberculin skin test (TST) has been the only assay used for detecting latent tuberculosis infection (LTBI), but two ex-vivo tests, used as alternative methods to TST, based on enumerating the M. tuberculosis-specific interferon (IFN)-γ response are now commercially licensed. The aim of this study was to compare the sensitivity and specificity of TST, QuantiFERON Gold (QFT-G), and T-SPOT.TB in diagnosing LTBI and active tuberculosis (TB). Materials and methods: This study was carried out with 95 participants including 3 groups (negative control, close contact, and patient groups) during a 10-month period from March 2007 to January 2008. Results: When the cut-off value of the TST was regarded as >=15 mm, 46.4% of the patients and 14.3% of the control group were found to have positive values. The sensitivity (51.4%) and the negative predictive value (NPV) (52.6%) of TST were lower than the specificity (83.3%) and the positive predictive values (PPV) (82.6%). The sensitivity and the PPV of the QFT-G test (78.4% and 76.3%, respectively) were higher than the specificity (62.5%) and NPV (65.2%). The PPV (81.8%) of the T- SPOT.TB test was higher than sensitivity (73.0%), specificity (75.0%), and NPV (64.3%). Conclusion: IFN-γ tests could be useful in diagnosing LTBI and chemo-prophylaxis, as the false negativity of the TST was higher compared to both QFT-G and T-SPOT.TB. However, additional studies are needed to assess better the utility of these tests with large populations.
