Effect of Watering Regime on Disease Development in Pinus sylvestris Seedlings Inoculated with Bursaphelenchus vallesianus and B. mucronatus.

Several Bursaphelenchus spp. have been detected in declining pine trees in Europe during intensive monitoring for the pine wood nematode B. xylophilus.

Micro-Media Systems anaerobe panel versus broth disk method in anaerobe antimicrobial testing.

Frozen microtitration trays manufactured by Micro-Media Systems (MMS) for antimicrobial testing of anaerobic bacteria were evaluated and compared with the broth disk elution method of Virginia Polytechnic Institute (VPI) described by Wilkins and Thiel. A total of 224 clinical anaerobic isolates were tested. Susceptibility results were compared for carbenicillin, cefoxitin, chloramphenicol, clindamycin, penicillin, and tetracycline.

Evaluation of the Minitek system for direct identification of anaerobic rods from positive blood cultures.

The direct inoculation of the Minitek anaerobe identification system (BBL Microbiology Systems, Cockeysville, Md.) from positive blood cultures was compared with subculture and Minitek results obtained using the manufacturer's recommended procedures. A total of 40 clinical anaerobic blood cultures were processed for rapid identification utilizing bacterial pellets obtained by centrifugation.
