Some Cultural Characters of Bacillus Abortus (bang) with Special Reference to Co2 Requirements
The relative absence of saprophytism in freshly isolated strains of Bacillus abortus is conveniently measured by inoculating a series of agar tubes with. successive dilutions of culture and sealing the tubes. The appearance of films of growth is delayed from 3 to 17 days and suppressed with the increase in the dilutions. As many as 100,000 bacteria per sq. cm. of agar surface are suppressed. Wh...
متن کاملVariations in Co2 Requirements among Bovine Strains of Bacillus Abortus
Strains of Bacillus abortus freshly isolated vary in their CO(2) requirements. The origin and sources of the strains growing with less dependence on CO(2) (or sealing) may be in vaccinal strains or possibly in continued existence in the udder. The importance of these possibilities makes it desirable that all strains isolated should be subjected to some such test as is outlined in these pages.
متن کاملAntimicrobial characteristics of some herbal Oils on Pseudomonas aeruginosa with special reference to their chemical compositions
Pseudomonas aeruginosa is an important opportunistic pathogen causing widespread infections by numerous virulence factors. Increasing resistance to antibiotics makes the Pseudomonas infections treatment further difficult. The purpose of this study was to evaluate antimicrobial characteristics of essential oils from Matricaria chamomilla, Artemisia persica, Zataria multiflora, Myrtus communis, R...

متن کاملStudies on Bacillus Welchii with Special Reference to Gas Gangrene
1. Spores of the Bacillus welchii group of bacteria were found on 100 per cent of the uniforms of Belgian soldiers who had come directly from the trenches, and in the meshes of all the samples examined of the new cloth from which the uniforms were made. 2. In fifteen out of twenty fresh war wounds members of this group of bacteria were found. Of the fifteen patients, only three later developed ...
