Heterogeneity in phenotypic and genotypic characteristics among strains of Hafnia alvei

Ceftazidime resistance in Hafnia alvei.

Two morphotypes of Hafnia alvei differed in their susceptibilities to beta-lactam antibiotics. Both produced an inducible Bush group 1 beta-lactamase. Hyperinducibility of this enzyme was associated with reduced susceptibility in one morphotype.

Genotypic and phenotypic heterogeneity in familial microcoria.

AIMS To describe the clinical features and genetic findings in two families presenting with microcoria inherited as an autosomal dominant trait. METHODS Both affected and unaffected members of two families displaying familial microcoria were examined. Flash photography or infrared pupillography were used to assess pupils, and a full ophthalmic examination including visual acuity and field tes...

Some phenotypic and genotypic characteristics of prevailing gonococcal strains in northern Norway.

Ninety two non-penicillinase producing Neisseria gonorrhoeae (non-PPNG) strains were investigated by the restriction enzyme technique with Hind III enzyme. Serogrouping by coenzyme. A with monoclonal antibodies and testing susceptibility to doxycycline were also performed by an agar dilution method. Fifteen different restriction enzyme patterns were shown, of which three represented 50% (46/92)...

Phenotypic and Genotypic Characteristics of Neisseria meningitidis Disease-Causing Strains in Argentina, 2010

Phenotypic and genotypic characterization of 133 isolates of Neisseria meningitidis obtained from meningococcal disease cases in Argentina during 2010 were performed by the National Reference Laboratory as part of a project coordinated by the PAHO within the SIREVA II network. Serogroup, serotype, serosubtype and MLST characterization were performed. Minimum Inhibitory Concentration to penicill...
