The activity of azlocillin, a new semisynthetic penicillin, was determined against 582 clinical isolates of gram-negative bacilli and gram-positive cocci. Over 75% of the isolates of Pseudomonas aeruginosa were inhibited at a concentration of 12.5 mug or less per ml. Azlocillin is also active against indole-negative and -positive Proteus spp., inhibiting 98 and 71%, respectively, at a concentra...

This study was carried out with the participation of eight hospitals in Turkey to determine the frequency of gram-negative bacteria isolated in intensive care units (ICU) and to compare their resistance rates to selected antibiotics. Aerobic gram-negative bacteria isolated from ICUs during 1996 were studied. Antibiotic susceptibilities to imipenem, ceftazidime, ceftazidime-clavulanate, ceftriax...

We investigated the bacterial flora present in skin lesions of patients with chiclero's ulcer from the Yucatan peninsula of Mexico using conventional culture methods (11 patients), and an immunocolorimetric detection of pathogenic Streptococcus pyogenes (15 patients). Prevalence of bacteria isolated by culture methods was 90.9% (10/11). We cultured, from chiclero's ulcers (60%), pathogenic bact...

BACKGROUND One important aspect in combatting resistance to antibiotics is to increase the awareness and knowledge by epidemiological studies. We therefore conducted a German-wide point-prevalence survey for multidrug resistant bacterial organisms (MDROs) and Clostridium difficile (CD) to assess the epidemiology and structure quality of infection control in German hospitals. METHOD 1550 hospi...

Cefepime is a fourth-generation cephalosporin which is approved in Europe and in the USA. Food and Drug Administration (FDA) approves cefepime in the treatment of febrile neutropenia. Cefepime is active against gram-negative microorganisms such as Escherichia coli, Haemophilus influenzae, Enterobacter, Klebsiella, Morganella, Neisseria, Serratia, and Proteus species. Cefepime is also active aga...

Cell yields of Pseudomonas fluorescens, Aerobacter cloacae UW-C83, Escherichia coli K-12, Candida utilis UW-3, and Saccharomyces carlsbergensis UW-110 grown aerobically on several carbon sources are reported. The Y(atp) concept is discussed in relation to the yields on oxygen and to assumed P to O ratios for bacteria and reported P to O ratios for yeast.

Infections due to Pseudomonas fulva remain a rare but emerging concern. A case of ventriculitis due to Enterobacter cloacae and Pseudomonas fulva following placement of an external ventricular drain is described. Similar to other reports, the organism was initially misidentified as Pseudomonas putida. The infection was successfully treated with levofloxacin.

The Australian Group on Antimicrobial Resistance (AGAR) performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2010 survey focussed on community-onset infections, examining isolates from urinary tract infections from patients presenting to outpatient clinics, emergency departments or to community practitioners. ...

Introduction: Diffusion of antibiotic resistance genes by horizontal gene transfer has led to the fast emergence of multidrug resistance (MDR) among bacteria. Multiple classes of integrons are effective genetic elements which play a significant role in the acquisition and nosocomial dissemination of resistance factors in strains of Gram-negative bacteria, Pseudomonas aeruginosa, and Acinetobact...
