TL;DR: Hematitis C virus and active intravenous drug use could be important factors in the morbidity and mortality among HIV-1-infected patients, possibly through impaired CD4-cell recovery in HCV seropositive patients receiving potent antiretroviral therapy.

TL;DR: Three DNA relatedness groups were associated with specific rRNA gene restriction patterns, protein electrophoresis patterns, and patterns of reactivity with murine monoclonal antibodies in Borrelia isolates associated with Lyme borreliosis.

TL;DR: One clone, marked by ET1, caused major epidemics of human disease in western Switzerland in the period 1983-1987 and in Los Angeles County, California, in 1985, both of which were attributed to contamination of soft cheese.

TL;DR: A new PCR method based on the 18S rRNA allowed the identification of three human pathogenic species: Babesia microti, B. divergens, for the first time in Switzerland, and Babesian sp.

TL;DR: The disappearance of the microorganism accompanied by the unequivocal decrease of most indicators of active T- and B-cell immune response strongly supported a pathogenetic role for B burgdorferi in sustaining an antigen-driven development and growth of this cutaneous marginal zone lymphoma.
