A rare case of neonatal meningoencephalitis from .

infections can be life threatening and are being reported with increasing incidence. There are only a few case reports of infections and are mainly described in patients who are immunocompromised, injection drug users, or those with prosthetic devices. Due to improved testing and identification, it appears that these infections may not be as rare as once perceived.

Pyelonephritis and Bacteremia from Lactobacillus delbrueckii.

Lactobacilli are normal colonizers of the oropharynx, gastrointestinal tract, and vagina. Infection is rare, but has been reported in individuals with predisposing conditions. Here we describe the case of a woman with pyelonephritis and bacteremia in which Lactobacillus delbrueckii was determined to be the causative agent.

Pseudomonas aeruginosa dihydroorotases: a tale of three pyrCs.

Pseudomonas aeruginosa PAO1 was shown to contain three pyrC sequences. Two of these genes, designated pyrC (PA3527) and pyrC2 (PA5541), encode polypeptides with dihydroorotase (DHOase) activity, while the third, pyrC' (PA0401), encodes a DHOase-like polypeptide that lacks DHOase activity, but is necessary for the structure and function of ATCase. Both pyrC and pyrC2 were cloned and complemented an Escherichia coli pyrC mutant.
