background and objective: cytomegalovirus (cmv) infections are associated with severe morbidity and mortality in patients, especially pediatric renal transplantation patients. the use of immunosuppressive agents places these patients at the risk of viral infections. as cytomegalovirus infection influences the graft outcome, adopting useful strategies for limiting this virus after transplantatio...

background and objectives: urinary tract infections (uti) are one of the most common infectious diseases with different microbial agent and antimicrobial resistant pattern in hospitalized patients and outpatients. in order to assess the adequacy of therapy, knowledge of prevalence and resistance pattern of the bacteria is necessary. the main aim of this study was to evaluate the prevalence and ...

introduction: the most common mode of rabies virus transmission is through a bite wound or contact of broken skin with saliva of a rabid animal. various other routes of virus transmission include exposure of mucous membranes (i.e. eyes, nose, and mouth) to infected saliva of a rabid animal, aerosol transmission, and corneal transplantation. laboratory workers during work with rabies virus and v...
