Strain-Specific Immunity Discovered for Lyme Disease

Many patients treated for early Lyme disease incur another infection in subsequent years, suggesting that previous exposure to Borrelia burgdorferi may not elicit a protective immune response.  More...

Blood Culture Diagnostic Techniques Compared for Human Brucellosis

Isolation of the bacteria Brucella is the gold standard in the laboratory diagnosis of brucellosis and as the organism is intracellular, the number of circulating bacteria is usually low.   More...
