Taxonomic Investigations on Expressed and Cryptic Phospho-β-glucosidases in Enterobacteriaceae
A screening test applied to strains belonging to several genera of Enterobacteriaceae showed that strains of Citrobacter, Hafnia, and Serratia exhibit a degree of similarity in phospho-beta-glucosidase activity and inducibility which could be useful in their taxonomic characterization. Expand
Inducible System for the Utilization of β-Glucosides in Escherichia coli I. Active Transport and Utilization of β-Glucosides
Autoradiography shows that TEG is accumulated by the β-glucoside permease and glucose permease in two different forms, and it is assumed that phosphorylated alkyl and thioalkyl β- glucosides inhibit the induction, and that this inhibition is responsible for the induction lag. Expand
Amikacin-resistant gram-negative bacilli: correlation of occurrence with amikacin use.
Data indicate that resistance to amikacin in this hospital is enzymatically mediated in most strains of AKR Klebsiella and Serratia and in about one-third ofAKR strains of P. aeruginosa. Expand
Regulation of the β-Glucoside System in Escherchia coli K-12
It is suggested that the ini mutation possesses a promotor-type function that in the absence of regulatory allele function ( bglR8 ) renews the functioning of only the bglS4 and bglB + alleles, which are proposed to form a bgl operon. Expand
Resistance of Staphylococcus aureus to semisynthetic penicillins and cephalothin.
Six strains of Staphylococcus aureus resistant to semisynthetic penicillins were recovered from clinical sources during a two-month period and each was resistant to oxacillin at low inocula. Expand

  • 1 February 1989
Since January 1988, Staphylococcus aureus strains with a high level of quinolone resistance have been isolated at 17 hospitals and 15 nursing homes in New York City. The majority of these strainsExpand
Nosocomial infection caused by gentamicin-resistant, streptomycin-sensitive Klebsiella.
Antibiotic sensitivity among gram-negative pathogens might be preserved by a program in which the use of highly effective agents is periodically rotated. Expand
Methicillin-Resistant Strains of Staphylococcus aureus Phage Type 92
Transduction experiments indicated that the transfer of chromosomal tetracycline resistance from Mecr strains into a strain susceptible to several international typing phages renders the latter nontypable, however, the acceptor strain remains susceptible to experimental phages 92 and 88. Expand
