Fluoroquinolone-resistant and extended-spectrum β-lactamase-producing Escherichia coli from the milk of cows with clinical mastitis in Southern Taiwan.

Background/purpose: Escherichia coli is a common pathogen to cause clinical and subclinical mastitis in cows. A total of 57 E. coli isolates from raw milk from cows were characterized genetically and biochemically.

Feature amplified voting algorithm for functional analysis of protein superfamily.

Background: Identifying the regions associated with protein function is a singularly important task in the post-genomic era. Biological studies often identify functional enzyme residues by amino acid sequences, particularly when related structural information is unavailable. In some cases of protein superfamilies, functional residues are difficult to detect by current alignment tools or evolutionary strategies when phylogenetic relationships do not parallel their protein functions.

Tuberculous spondylitis and pyogenic spondylitis: comparative magnetic resonance imaging features.

Study Design: We retrospectively compared magnetic resonance images (MRIs) of tuberculous (TB) spondylitis and pyogenic spondylitis.

Objective: To identify differences between the diseases.

Summary Of Background Data: Clinical and imaging findings of the 2 diseases are hard to distinguish.
