Cephalosporins possessing a 1, 3-dithiolane, 1, 3-dithiane, or 1, 3-dithietane ring on their 7 beta-substituents showed potent inhibitory activity against cephaloridine hydrolysis by cephalosporinases purified from proteus morganii, Proteus rettgeri, and Proteus inconstans, which were not inhibited by clavulanic acid, a well-known beta-lactamase inhibitor. The mode of inhibition was competitive...

BL-S 640 was evaluated in vitro by comparison with cephalothin, cephaloridine, cefazolin, and cephalexin. The new compound was more active than the control cephalosporins against most major gram-negative and some gram-positive species. Moreover, its antibacterial spectrum included strains of Enterobacter, Proteus morganii, P. rettgeri, and Providencia stuartii, species generally resistant to th...

INTRODUCTION Abscess formation and cellulitis in the setting of envenomation are rare complications of handling catfish. To the best of our knowledge, isolation of Proteus vulgaris has not been previously recorded, and recovery of Morganella morganii has been reported in only one prior case from wound cultures in patients injured by catfish stings. We report a case of catfish envenomation chara...

The so-called Proteus-Providencia group is constituted at present by three genera and 10 species. Several of the recognized species are common opportunistic pathogens for humans and animals. Different methods based on the study of phenotypic characters have been used in the past with variable levels of efficiency for typing some species for epidemiological purposes. We have determined the rRNA ...

Information regarding bacterial diseases in Cuvier’s beaked whale (CBW, Ziphius cavirostris) is scattered and mostly incomplete. This report describes a case of septicemia by Morganella morganii juvenile male CBW with concurrent renal crassicaudiasis. The animal stranded along the Ligurian coastline (Italy) underwent systematic post-mortem examination to determine cause death. Histopathology sh...
