From 1990 to 1992, 600 significant isolates of H. influenzae obtained from various hospitals throughout Saudi...

...Walter H. Traub; Birgit Leonhard Haemophilus test medium (HTM) was compared with Wilkins-Chalgren agar (WCA; supplemented with 15 μg/ml nicotinamide adenine dinucleotide (NAD)) for antibiotic susceptibility testing of 74 clinical isolates of Haemophilus influenzae and Haemophilus parainfluenzae...

... of Streptococcus pneumoniae , Haemophilus influenzae and Moraxella catarrhalis from otic exudates, exudates obtained by puncture of the paranasal sinuses, sputum samples or blood cultures obtained from hospital inpatients with symptoms of significant upper or lower respiratory tract infection were analyzed...

...Patricia A. Fontán; Fernanda R. Buzzola; Emma G. Spinedi; Daniel O. Sordelli The capacity of phagocytes to concentrate macrolide antibiotics was suggested by previous reports. In this study, we evaluated the capacity of Haemophilus influenzae type b culture supernatants (HICS) to induce...

...C. Jallat; A. Darfeuille-Michaud; C. Forestier; B. Joly; R. Cluzel We studied the effect of subinhibitory concentrations of cefuroxime on the capacity of Haemophilus influenzae to adhere to buccal epithelial cells (BEC). Two encapsulated strains (serotype b) and two nonencapsulated, nontypable...

...E. Yourassowsky; M.P. Van der Linden; F. Crokaert Phase contrast microscopy, killing curves and turbidimetric growth curves were used in a comparative study of the antibacterial effects of imipenem and meropenem on Haemophilus influenzae . The minimal inhibitory concentrations (MICs...

...Toshihiko Yamada; Yoshiko Yokota; Fumiaki Ikeda; Yasuhiro Mine; Takahide Kitada We measured the sizes of the inhibition zones of oral β-lactam antibiotics for Streptococcus pneumoniae, Streptococcus pyogenes and Haemophilus influenzae in the presence of β-lactamase-producing- Moraxella (Branhamella...

...Carl W. Norden; Kerry Niederriter BMY-28100 is a new orally absorbed cephalosporin whose in vitro activity was compared with that of cefaclor. BMY-28100 was more active against Staphylococcus aureus and Haemophilus influenzae than was cefaclor. In addition, there was only a small rise in MIC 50...

...M.M. Shelton; D.F. Welch The activities of ampicillin, cefaclor, cephalothin, and cefuroxime against invasive clinical isolates of Haemophilus influenzae were studied to determine the correlation between resistance and β-lactamase production. Approaches to in vitro susceptibility testing...

...Elizabeth A. Jurek; Leonard B. Weiner; Paul A. Granato The in vitro activity of rosoxacin was compared to that of ampicillin, cefoxitin, chloramphenicol, and rifampin, against 94 clinical isolates of Haemophilus influenzae .The results indicated that rosoxacin had significantly better in vitro...

...R.R. Whitney; R.J. McRipley; H.H. Gadebusch Procedures for evaluating the efficacy of chemotherapeutic agents in an infant rat model of Haemophilus influenzae meningitis were developed. The results of efficacy studies with ampicillin, chloramphenicol, cefamandole, cefoxitin, and SQ 13,426 were...

... at the pathogen Haemophilus influenzae [7], An exam­ ple of this is the suggestion that penicillinase-susceptible penicillins may INGOLD 89 be inactivated by penicillinase (/5-lactamase) producing bacteria in chronic bronchial infections [6,1, 11]. This paper describes a method to estimate the amount...

... and bacteriological follow-up after treatment. The pathogens were β -haemolytic streptococcus, group A (29 cases), pneumococcus (6 cases) and Haemophilus influenzae (6 cases); in one case, the pneumococcus and H. influenzae were present together. The results of doxycycline therapy were excellent, this included both...

... concentrations, while those in homogenized bronchial wall specimens were slightly lower than the serum readings. All these concentrations were on average considerably higher than the minimum inhibitory concentrations for the pneumococcus and Haemophilus influenzae. The comparatively low bronchial secretion...

...Nevriye Gonullu; Fadimana Catal; Omer Kucukbasmaci; Sinem Ozdemir; Muzeyyen Mamal Torun; Rahmiye Berkiten Background: We compared the in vitro activities of tigecycline with those of other agents against 97 Streptococcus pneumoniae, 140 Haemophilus influenzae and54 Moraxella catarrhalis strains...
