Genetically modified potatoes expressing antibacterial protein T4 lysozyme may offer effective control strategies for bacterial pathogens causing severe potato diseases. Apart from this beneficial effect, it is very important to investigate such engineered potatoes carefully for potential adverse effects on potato-associated bacteria which frequently(More)
A range of European habitats was screened by PCR for detection of the oxytetracycline resistance genes otr(A) and otr(B), found in the oxytetracycline-producing strain Streptomyces rimosus. Primers were developed to detect these otr genes in tetracycline-resistant (TcR) streptomycete isolates from environmental samples. Samples were obtained from bulk and(More)
Numbers of bacilli resistant to each one of 6 antibiotics were determined in samples of 5 different Brazilian soils. In all soils, antibiotic-resistant cells made up only a minor part of the total population of bacilli. Resistance to penicillin (Pc), streptomycin (Sm) and kanamycin (Km) was most frequent in the majority of soils, however, numbers of bacilli(More)
