متن کاملCitrobacter diversus ULA-27 beta-lactamases. Improved purification and general properties.
Two chromosome-encoded beta-lactamases have been purified from Citrobacter diversus ULA-27. They exhibited slightly different isoelectric points (6.8 and 6.2) and very similar Mr values (congruent to 29,000). Their specificity spectrum was rather wide, since they hydrolysed some cephalosporins with kcat: values similar to those observed with the best penicillin substrates. Cloxacillin, methicil...
متن کاملCitrobacter diversus isolated from clinical material.
Forty-seven strains of Citrobacter diversus were isolated during a 12-month period from clinical material obtained from patients in a general hospital in Israel. The majority of cultures (38) were recovered from urine and wound discharges. There was one case of septicemia. The biochemical reactions of all cultures were typical for this species, except one that was anaerogenic, and they could be...
متن کاملRecognition of Citrobacter diversus in the clinical laboratory.
Characteristics and antibiotic sensitivities of Citrobacter diversus are described, and a minimal number of diagnostic tests to identify this organism in a clinical laboratory are suggested.
متن کاملBrain abscess by citrobacter diversus in infancy: case report.
Citrobacter diversus is closely related to brain abscess in newborn infants. We describe a case of brain abscess by this bacteria in a newborn infant and his clinical and cranial computed tomographic evaluation until the fourth month of life and discuss therapeutic management of this patient.
