| ABSTRACT: Equid alphaherpesvirus type 1 (EHV-1) is distributed worldwide and is a major agent of abortion, respiratory and neurological disease in horses. No specific treatment is available for EHV-1 infection, yet the potential of antiviral therapy has been explored. In this study we investigated the in vitro activity of Acyclovir, Ganciclovir, Foscarnet, Famciclovir, Vidarabina and Cidofovir against EHV-1. For this, the MTT test was performed, in which all the tested drugs showed no toxicity up to 200μg/mL. Subsequently, different drug concentrations were submitted to viral plaque reduction assays in cell culture. The selectivity index (SI) of the compounds was determined using the cytotoxic concentration for 50% of cells (CC50), obtained by MTT, and... |

| The emergence of ganciclovir (GCV) resistance during the treatment of human cytomegalovirus (HCMV) infection is a serious clinical challenge, and is associated with high morbidity and mortality. In this case report, we describe the emergence of two consecutive mutations (A594V and L595W) related to GCV resistance in a patient with HCMV retinitis and long-term HIV progression after approximately 240 days of GCV use. Following the diagnosis of retinitis, the introduction of GCV did not result in viral load reduction. The detected mutations appeared late in the treatment, and we propose that other factors (high initial HCMV load, previous GCV exposure, low CD4+ cell count), in addition to the presence of resistance mutations, may have contributed to the... |

| The best strategy for control of cytomegalovirus (CMV) infection in lung transplant patients is still not determined. The aim of this study was to document the incidence of CMV infection in a cohort of lung transplant recipients under universal prophylaxis with intravenous ganciclovir. All patients received immunosuppressive regimens consisting of cyclosporine, azathioprine, and prednisone. Regardless of CMV serostatus, intravenous ganciclovir was prescribed for every patient in the first 3 months post-transplantation. CMV infection was defined as the detection of CMV pp65 in leukocytes. Eighty-two lung transplant patients were included over a 5-year period. The incidence of CMV infection in the first year post-transplantation was 68.3%, occurring after a... |
