Listeria monocytogenes is a human intracellular pathogen able to colonize host tissues after ingestion of contaminated food, causing severe invasive infections. In order to gain a better understanding of the nature of host-pathogen interactions, we studied the L. monocytogenes genome expression during mouse infection. In the spleen of infected mice, approximately 20% of the Listeria genome is d...
A multi-virulence-locus sequence typing (MVLST) scheme was developed for subtyping Listeria monocytogenes, and the results obtained using this scheme were compared to those of pulsed-field gel electrophoresis (PFGE) and the published results of other typing methods, including ribotyping (RT) and multilocus sequence typing (MLST). A set of 28 strains (eight different serotypes and three known ge...
The carbon metabolism of Listeria monocytogenes (Lm) EGD and the two isogenic mutant strains LmDeltaprfA and LmDeltaprfApPRFA* (showing no or enhanced expression, respectively, of the virulence factor PrfA) was determined by 13C isotopologue perturbation. After growth of the bacteria in a defined medium containing a mixture of [U-13C6]glucose and glucose with natural 13C abundance (1:25, wt/wt)...
Occipital neuralgia is a condition manifested by chronic occipital headaches and is thought to be caused by irritation or trauma to the greater occipital nerve (GON). Treatment for occipital neuralgia includes medications, nerve blocks, and pulsed radiofrequency ablation (PRFA). Landmark-guided GON blocks are the mainstay in both the diagnosis and treatment of occipital neuralgia. Ultrasound is...
