1. Multilocus-sequence typing analysis reveals similar populations of Streptococcus uberis are responsible for bovine intramammary infections of short and long duration.
Match Strength: 5.196
Multilocus-sequence typing (MLST) was used to analyse Streptococcus uberis isolates from a single herd associated with long duration (50-260 days) and rapidly cleared (less than 1 month) bovine intramammary infections to determine whether the bacterial type had any impact on the duration of infection. Most chronic infections (24 of 33) were due to continuous infection of the mammary quarter with the same sequence type, and infections were found to persist for many months. The remaining quarters were re-infected with a different sequence type within a single lactation. No particular sequence ... Read More »

2. Emerging fungi.
Match Strength: 4.928
The hyalohyphomycetes (especially Fusarium spp) have emerged as significant pathogens in severely immunocompromised patients. Human infections by Fusarium spp can be superficial or limited to single organs in otherwise healthy patients. Such infections are rare and tend to respond well to therapy. By contrast, disseminated fusarial hyalohyphomycosis affects the immunocompromised host and frequently is fatal. Successful outcome is determined by the degree of immunosuppression and the extent of the infection. These infections may be suspected clinically on the basis of a constellation of ... Read More »

3. Periodontal infections and atherosclerotic vascular disease: an update.
Match Strength: 4.668
The role of periodontal infections as a putative risk factor for atherosclerotic vascular disease (ASVD) has been reported in the literature over the past decade. This review provides insights into biologically plausible pathways that can potentially mediate such an association, and discusses recent findings from epidemiological studies and intervention trials. Accumulating epidemiological evidence suggests that clinical, microbiological and serological markers of periodontal infection are associated with subclinical and manifest ASVD. Early evidence from intervention studies suggests that the ... Read More »

5. Communicable respiratory threats in the ED: tuberculosis, influenza, SARS, and other aerosolized infections.
Match Strength: 4.373
Respiratory infections are the most common communicable infectious diseases. EDs are the front line for patients with respiratory infections because of their acute nature and because the ED is the principal site of health care for those at highest risk. These diseases include influenza, tuberculosis, and measles, together accounting for 25% of infectious causes of death worldwide. These are emerging and biothreat agents that follow the same route of transmission, such as pneumonic plague. We discuss epidemiology, pathogenesis, diagnosis, and treatment of each agent. Emphasis is on the ED's ... Read More »

6. Mendelian resistance to human norovirus infections.
Match Strength: 4.332
Noroviruses have emerged as a major cause of acute gastroenteritis in humans of all ages. Despite high infectivity of the virus and lack of long-term immunity, volunteer and authentic studies has suggested the existence of inherited protective factors. Recent studies have shown that histo-blood group antigens (HBGAs) and in particular secretor status controlled by the alpha1,2fucosyltransferase FUT2 gene determine susceptibility to norovirus infections, with nonsecretors (FUT2-/-), representing 20% of Europeans, being highly resistant to symptomatic infections with major strains of norovirus. ...
