Comparison of susceptibility of gentamicin-resistant and -susceptible "Acinetobacter anitratus" to 15 alternative antibiotics.
Fifty-four clinical isolates of "Acinetobacter anitratus" separated cleanly into gentamicin-susceptible (16 strains) and gentamicin-resistant (38 strains) subpopulations. When tested with a 10(4)-CFU inoculum, gentamicin resistance was associated with a greater than fourfold increase in the MICs of norfloxacin, ciprofloxacin, A-56620, tobramycin, and amikacin for 50% of the strains. Antimicrobi...
متن کاملMtx toxins synergize Bacillus sphaericus and Cry11Aa against susceptible and insecticide-resistant Culex quinquefasciatus larvae.
Two mosquitocidal toxins (Mtx) of Bacillus sphaericus, which are produced during vegetative growth, were investigated for their potential to increase toxicity and reduce the expression of insecticide resistance through their interactions with other mosquitocidal proteins. Mtx-1 and Mtx-2 were fused with glutathione S-transferase and produced in Escherichia coli, after which lyophilized powders ...
متن کاملDetection of Paenibacillus larvae larvae spores in honey and diseased larvae Samples by culture and PCR
American foulbrood (AFB) is the most serious brood disease of the honey bee. Traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. The aim of this study is the detection of Paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and PCR. Therefore 54 samp...
متن کاملLaboratory evaluation of cyromazine against insecticide-susceptible and -resistant mosquito larvae.
In this study, the activity of cyromazine was evaluated following WHO standard procedures against susceptible and resistant mosquito strains of Anopheles gambiae, Culex quinquefasciatus, and Aedes aegypti. The dose for 50% and 90% inhibition of adult emergence (IE50 and IE90) ranged from 0.028 mg/liter to 0.17 mg/liter and from 0.075 mg/liter to 0.42 mg/liter, respectively. The effects of cyrom...
متن کاملIn-vitro activity of 21 beta-lactam antibiotics against penicillin-susceptible and penicillin-resistant Streptococcus pneumoniae.
MICs of 21 beta-lactams were determined by agar dilution against 283 penicillin-susceptible (pen-S), 122 intermediate (pen-I) and 23 fully penicillin-resistant (pen-R) pneumococci. MICs of all beta-lactams increased with increasing MICs of penicillin. Clometocillin was the most active penicillin against pen-I or pen-R pneumococci. All oral cephalosporins except cefuroxime and cefpodoxime were l...
