In vitro susceptibility of Bacillus anthracis to various antibacterial agents and their time-kill activity.

OBJECTIVES To investigate the in vitro acquisition of resistance to antibiotics by Bacillus anthracis. METHODS The in vitro activities of 18 antibacterial agents against two strains of B. anthracis, the Sterne strain and the Russian anthrax vaccine strain ST-1, were tested by determining the MICs and by measuring the rates of antibiotic kill at 5x and 10x MIC. RESULTS The fluoroquinolones c...

Two Proteins from Snake Venom have Potent Antibacterial Effects against Bacillus anthracis and Streptococcus pneumoniae

Background: Antibacterial proteins are widely expressed in snake venoms. Previously, we have isolated two immunodominant proteins with molecular weights of 14 and 65kD from the snake venom of Naja naja oxiana (N. oxiana). It was demonstrated that they had potent inhibitory effects against gram-positive bacteria, S. aureus and B. subtilis but were less effective against gram-negative bacteria, s...

Transduction in Bacillus cereus and Bacillus anthracis.

A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...

Ruling Out Bacillus anthracis

Optimization of methods for ruling out Bacillus anthracis leads to increased yields, faster turnaround times, and a lighter workload. We used 72 environmental non-B. anthracis bacilli to validate methods for ruling out B. anthracis. Most effective were the use of horse blood agar, motility testing after isolates had a 2-h incubation in trypticase soy broth, and screening isolates with a B. anth...

Lecithinase from Bacillus anthracis.

When Bacillus anthracis is grown in egg yolk medium, a reaction occurs which is presumably due to lecithinase (Colmer, 1948; McGaughey and Chu, 1948; Chu, 1949). In liquid egg yolk medium the lecithinase reaction is characterized by the formation of an opalescent suspension and flocculation of particles which rise to the top of the medium as a curd. A test such as this is usually referred to as...
