Expert review of anti-infective therapy
-
Following Epstein and colleagues' ground-breaking discovery of Epstein-Barr virus by electron microscopy of Burkitt's lymphoma cell lines, there came the observation that Epstein-Barr virus induces immortalization of B cells in vitro. Thus, initial hopes were of a virus confined to equatorial Africa with a causal link to a particular subtype of childhood lymphoma. ⋯ Infection in New World primates leads to lymphoma and inoculation of peripheral blood mononuclear cells from Epstein-Barr virus-seropositive subjects into severe combined immunodeficiency mice results in B-cell lymphoproliferative disorders. Epstein-Barr virus is now known to be implicated in a range of lymphoid and other malignancies, and this association will be the subject of this review.

ReviewDevelopment of treatment strategies to combat Ebola and Marburg viruses.
Ebola and Marburg viruses are emerging/re-emerging pathogens that pose a significant threat to human health. These naturally occurring viral infections frequently cause a lethal hemorrhagic fever in humans and nonhuman primates. ⋯ The recognition that Ebola and Marburg viruses may be exploited as biological weapons has resulted in major efforts to develop modalities to counter infection. In this review, select technologies and approaches will be highlighted as part of the critical path for the development of therapeutics to ameliorate the invariably devastating outcomes of human filoviral infections.

ReviewPharmacological advances in the treatment of invasive candidiasis.
Invasive candidiasis is a common nosocomial infection, especially among the critically ill and immunocompromised patient populations. The recent standardization and increasing availability of antifungal susceptibility testing has the potential to optimize the selection of antifungal therapy. ⋯ While more expensive by acquisition cost, these newer agents are less toxic than the previously used drugs, and the triazoles offer the additional benefit of oral administration. The availability of new agents, future adoption of diagnostic tests for candidiasis, and susceptibility testing will have a major impact in the management of invasive candidiasis.

ReviewMechanisms of resistance to beta-lactams in some common Gram-negative bacteria causing nosocomial infections.
Gram-negative bacilli remain major killers of hospitalized patients and continue to evolve new resistance mechanisms. This review describes the mechanisms of resistance to beta-lactam antibiotics from those Gram-negative pathogens most often isolated from nosocomial infections.

Nosocomial infections are the most frequent complications observed in surgical patients. In colorectal surgery, the opening of the viscera causes the dissemination into the operative field of microorganisms originating from endogenous sources, increasing the chance of developing postoperative complications. ⋯ This percentage decreases to approximately 11% after antibiotic prophylaxis. Specific criteria in the choice of correct antibiotic prophylaxis have to be respected, on the basis of the microorganisms usually found in the surgical site, and on the specific hospital microbiologic epidemiology.
