[Latent tuberculosis infection: prevalence amongst healthcare students at the Sapienza University of Rome (Italy)].

Healthcare workers, including medical, dentistry and nursing students, have an increased risk of Mycobacterium tuberculosis infection. In this study the prevalence of tuberculin skin test (TST) positivity (defined as induration ≥ 5 mm) among healthcare students enrolled at the Sapienza University of Rome (Italy) in the years 2011-2012 was evaluated. Overall, 2,519 students with a mean age of 20.

[Control and prevention of tuberculosis in healthcare facilities].

Tuberculosis remains the leading cause of death by a single infectious agent. Healthcare workers who for professional reasons are exposed to infectious patients and to potentially contaminated materials are at high risk of infection. This article provides a review of existing regulations and summarizes national and international guidelines and operational protocols for tuberculosis surveillance in clinical settings.

Morphometric variability between and within species of Ligophorus Euzet & Suriano, 1977 (Monogenea: Ancyrocephalidae) in the Mediterranean Sea.

Monogeneans belonging to the genus Ligophorus Euzet & Suriano, 1977 are parasitic on the gills of several fish species of the family Mugilidae (mullets). At present, 12 species belonging to this genus have been described in the Mediterranean Sea and each host species is infected by a number of Ligophorus species that are not found on other mullets. A multivariate study using principal component and canonical variate analyses was carried out, with the aim of investigating the extent of morphometric variability within and between the 12 Mediterranean species of Ligophorus.
