Prophylactic penicillin has been recommended for use in asplenic patients and postsplenectomy patients. A laboratory model using aerosolized pneumococci has been devised to test the effectiveness of prophylactic penicillin in a manner analogous to human experience. There is increased mortality. over time, in asplenic mice exposed to aerosolized type Ill Streptococcus pneumoniae. One hundred twe...

The effectiveness of cephalexin, an oral cephalosporin using a dosage equivalent to available capsular dosage forms, was studied in relation to the effectiveness of phenoxymethyl penicillin and benzathine penicillin in the treatment of 128 patients with beta-hemolytic streptococcal pharyngitis, all but six of whom had group A streptococci isolated from throat cultures. Approximately one-half, 6...

WHAT IS KNOWN Penicillin allergy limits therapeutic options for patients but often disappears over time, leaving patients erroneously labelled allergic and leading to the utilization of broad-spectrum and more expensive antibiotics. Penicillin allergy can be effectively assessed via skin testing. OBJECTIVE To improve patient access to penicillin allergy testing by implementing a pharmacist-pr...

Respiratory infections with penicillin resistant pneumococci constitute an increasing health care problem. This paper describes the nosocomial spread of penicillin resistant pneumococci (PRP) on a pulmonary ward. During an eight-month period, minimal inhibitory concentrations (MICs) for penicillin and several other antibiotics were performed on all Streptococcus pneumoniae isolates that were sh...

[%]Penicillin G bound to the Bacillus subtilis and Bacillus stearothermophilus D-ala&e carboxypeptidases in either the membrane-bound or purified states. ‘Ihis binding was subsequently reversed with a half-time ranging from 10 min to several days, depending on the enzyme, the penicillin derivative, and the temperature. The released material was neither intact penicillin nor penicilloic acid but...

The purpose of this study was to compare the management of patients with a history of penicillin allergy between allergists and non-allergists in Thailand. A questionnaire was distributed to Thai physicians by online survey. The answers from 205 physicians were analyzed. The discrepancy of penicillin allergy management between allergists and non-allergists was clearly demonstrated in patients w...
