ABSTRACT Chromobacterium violaceum is a rare opportunistic pathogen that causes highly fatal infections in domestic animals and humans. This report describes a fatal case suggestive of septicemia in a four-day-old female calf with chromobacteriosis. The calf had suppurative omphalophlebitis, suppurative fibrinous polyarthritis, anterior uveitis with bilateral fibrin deposition, fibrinous peritonitis, lymph node abscess and multifocal lymphocytic and neutrophilic encephalitis with multifocal hemorrhages. C. violaceum was isolated from the spleen and peri-renal lymph node and its identity was confirmed by PCR and sequencing. The pathogen was sensitive to azithromycin, gentamicin, enrofloxacin, norfloxacin, marbofloxacin, ciprofloxacin, erythromycin,... |

Several studies of the physiological responses of different organisms exposed to extremely low-frequency electromagnetic fields (ELF-EMF) have been described. In this work, we report the minimal effects of in situ exposure to ELF-EMF on the global protein expression of Chromobacterium violaceum using a gel-based proteomic approach. The protein expression profile was only slightly altered, with five differentially expressed proteins detected in the exposed cultures; two of these proteins (DNA-binding stress protein, Dps, and alcohol dehydrogenase) were identified by MS/MS. The enhanced expression of Dps possibly helped to prevent physical damage to DNA. Although small, the changes in protein expression observed here were probably beneficial in helping the... |
