Methods for Studying Motor-Driven Viral DNA Packaging in Bacteriophages phi29, Lambda, and T4 via Single DNA Molecule Manipulation and Rapid Solution Exchange.

Viral DNA packaging is a required step in the assembly of many dsDNA viruses. A molecular motor fueled by ATP hydrolysis packages the viral genome to near crystalline density inside a pre-formed prohead shell in ~5 min at room temperature in vitro. We describe procedures for measuring the packaging of single DNA molecules into single viral proheads with optical tweezers.

Characterization of a novel SNP identified in Australian group A isolates derived from the M1 lineage.

Group A (GAS) is a human-adapted pathogen responsible for a variety of diseases. The GAS M1 lineage has contributed significantly to the recently reported increases in scarlet fever and invasive infections. However, the basis for its evolutionary success is not yet fully understood.

[Female urinary incontinence - diagnostics and therapies].

Urinary incontinence is a common complaint of both general practitioners and specialists. An accurate basic diagnosis with a structured medical history and bladder diary, urine analysis, gynaecological examination including pelvic floor assessment and a full bladder cough test can be supplemented by sonography, cystoscopy and urodynamic testing. This will help to differentiate between the different types of urinary incontinence, such as urge incontinence, stress incontinence and overflow incontinence.

A conserved burn wound infection model for diverse pathogenic fungi.

Unlabelled: Secondary fungal infections represent a major complication following thermal injuries. However, the mechanisms of fungal colonization of burn tissue and how the host subsequently responds to fungi within this niche remain unclear. We have previously reported a zebrafish model of thermal injury that recapitulates many of the features of human burn wounds.

The Influence of Fatty Acid Oxygenases PpoA and PpoC on Caspofungin Susceptibility.

can cause invasive pulmonary aspergillosis (IPA). Fungicidal azoles and fungistatic caspofungin (CAS) are the first- and second-line therapies, respectively, used to treat IPA. Treatment of with CAS or micafungin induces the production of the oxylipin 5,8-diHODE by the fungal oxygenase PpoA.
