The Cathra system is a commercial multipoint inoculation method for the identification of aerobic Gram negative bacteria. The system uses a replicator technique in which 21 different agar media can be inoculated simultaneously with 36 organisms. Identifications are made by use of a special computer database. The performance of this system was compared with that of the API 20E for the identifica...

The in vitro susceptibilities of 90 clinical isolates of gram-positive and gram-negative aerobic bacteria to six cationic peptides, buforin II, cecropin P1, indolicidin, magainin II, nisin, and ranalexin, were evaluated by two broth microdilution methods. The first method was performed according to the procedures outlined by the National Committee for Clinical Laboratory Standards for bacteria ...

Rifampin is a broad-spectrum, concentration-dependent, bactericidal and/or bacteriostatic antibiotic, with activity against many gram-positive and some gram-negative aerobic bacteria as well as facultative anaerobic organisms (Wilson et al., 1988). It is a complex macrocyclic semisynthetic antibiotic derived from rifamycin B. The principle use of rifampin in equine medicine is for combination t...

Velvet pads have been evaluated in an experimental, laboratory model, simulating intraoperative sampling of Staphylococcus epidermis, Escherichia coli and Bacteroides fragilis. After sampling, the pad was placed in a transport medium and kept in an anaerobic atmosphere, before being shaken and rinsed, followed by anaerobic and aerobic culture. This technique permitted quantitatively high recove...

The clinical efficacy of ciprofloxacin was evaluated with 21 patients with soft tissue infection due mainly to gram-negative aerobic bacteria. Clinical cure was noted in 16 patients (76%), and clinical improvement was noted in the remaining 5 patients (24%). In addition, levels of ciprofloxacin were measured in the sera and tissues of 11 patients. Mean concentrations in tissue averaged 1.75 tim...

The aerobic anoxygenic phototrophic bacteria are a relatively recently discovered bacterial group. Although taxonomically and phylogenetically heterogeneous, these bacteria share the following distinguishing features: the presence of bacteriochlorophyll a incorporated into reaction center and light-harvesting complexes, low levels of the photosynthetic unit in cells, an abundance of carotenoids...

A retrospective review of the microbiological and clinical data of 17 specimens obtained from axillary hidradenitis suppurativa (HS) over a period of 6 years was undertaken to study the aerobic and anaerobic microbiology of this condition. A total of 42 bacterial isolates (2.5 per specimen) were obtained, 12 aerobic or facultative (0.7 per specimen) and 30 anaerobic or micro-aerophilic (1.8 per...
