MICs of Selected Antibiotics forBacillus anthracis,Bacillus cereus,Bacillus thuringiensis, andBacillus mycoidesfrom a Range of Clinical and Environmental Sources as Determined by the Etest

Abstract

This paper presents Etest determinations of MICs of selected antimicrobial agents for 76 isolates of

Diversity of Bacillus thuringiensis in the rice field soils of different ecologies in India

“…All isolates were sensitive to twelve different Gram (+)ve specifi c and broad spectrum antibiotics (Table 1). Broadly, the isolates were resistant to the penicillin group but strictly, the BT1 and 2 were resistant to penicillin, ampicillin and amoxicillin; BT4 was resistant to penicillin and ampicillin and BT5 is resistant to ampicillin and amoxicillin (Table 1) which was in agreement with other Bt 4,9 . The biochemical and physiological characters revealed that the BT3, 7, 9, 11 and 12 were similar i.e.…”

Prevalence and Characterization of Bacillus cereus in Meat and Meat Products in and around Jammu Region of Jammu and Kashmir

“…In the present study, B. cereus was found susceptible to Aminoglycosides (gentamycin, neomycin and streptomycin) and chloramphenicol which is similar to the results of Luna et al, (2007) who reported that B. cereus isolates were susceptible to aminoglycosides, chloramphenicol, clindamycin, erythromycin, tetracyline and vancomycin. Previous works on the antimicrobial susceptibility of B. cereus revealed higher sensitivity towards ampicillin, amoxicillin and less susceptible to streptomycin, chloramphenicol, and neomycin as reported by Turnbull et al, (2004), Meena et al, (2000) and Schlegova et al, (2003). However erythromycin showed a resistance of (27.2%) which is in agreement to Wong et al, (1988) as some B. cereus isolates could attain resistance due to indescriminate use of these antibiotics in feeds and chemotherapy.…”

Pre- and postexposure protection against virulent anthrax infection in mice by humanized monoclonal antibodies to Bacillus anthracis capsule

“…The current Centers for Disease Control recommendations for treatment following potential exposure to aerosolized B. anthracis spores calls for administration of antibiotics for at least 60 d and the licensed protective antigen-based vaccine (1). However, antibiotic treatment can be ineffective when bacterial strains are antibiotic resistant (2). An alternative to treatment with antibiotics is desirable.…”
