Kovacs indole reagent, p-dimethylaminobenzaldehyde, Ehrlich indole reagent and p-dimethylaminocinnamaldehyde were used as spot indole reagents to test 359 strains of gram-negative rods growing on 5% sheep blood agar, Trypticase soy agar (BBL Microbiology Systems), and MacConkey agar. The p-dimethylaminocinnamaldehyde reagent was the most sensitive of those tested and provided results that were ...

Forty primary clinical isolates and 50 stock cultures of corynebacteria and coryneform bacteria were tested with the Minitek system (BBL Microbiology Systems, Cockeysville, Md.). The Minitek correctly identified all of these organisms, including JK group isolates, within 12 to 18 h of incubation. The method does not require serum supplements for testing carbohydrate utilization by the bacteria....

We report results on polarization-dependent photoinduced discharge in oriented fibers and films of ladder-type, electron-transporting polymer poly (ben-zimidazobenzophenanthroline), BBL. The photocarrier generation efficiency (φ) in the fiber which is indicated by the rate of discharge, is found to be distinctly higher for light polarized parallel to the fiber axis (P) as compared to the radial...

One of the growth media in current use for Haemophilus ducreyi comprises Mueller Hinton agar, chocolatised horse blood, serum and IsoVitalex (BBL). For a better understanding of growth factors, attempts were made to simplify this complex medium. The horse blood was replaced by haemin (200 micrograms/ml), the serum by albumin (0.2%), and IsoVitalex was substituted only by L-glutamine 0.01%. Most...

Acinetobacter baumannii is an important pathogen in hospitalized patients, particularly those in the intensive care unit (ICU). A total of 21 A. baumannii (6 from 5 patients and 15 from environmental samples) were isolated in the ICU and the isolation room of a state hospital in June 2011. The possible source of the outbreak was investigated. A. baumannii isolates were identified using conventi...

The Directigen 1,2,3 Group A Strep Test (DGAST; BBL Microbiology Systems, Cockeysville, Md.) was compared with conventional culture methods for the detection of group A streptococci. Among 327 children, the DGAST has a sensitivity of 75.0%, a specificity of 99.1%, and positive and negative predictive values of 97.5 and 89.3%, respectively, as compared with 48-h culture results. The lower sensit...

Bayi Baru Lahir (BBL) harus menyesuaikan diri dari kehidupan intrauterin ke ekstrauterin. Salah satu adaptasi BBL normal adalah mengatur suhu tubuh walaupun sangat rentan untuk mengalami hipotermi, yanag menjadi penyebab yang serius terhadap kesakitan dan kematian BBL. Tujuan penelitian mengetahui Faktor-Faktor Mempengaruhi Perubahan Temperatur Tubuh Sesudah 2 jam Post Partum di Rumah Sakit Col...
