The introduction of new antibiotic compounds into therapy initiates the development of resistance by the target bacteria. Resistance increases the risk of treatment failure with potentially serious consequences. Local application of antibacterial compounds to the eyes may lead to bacterial resistance in bacterial isolates from the eyes. The incidence of resistant strains of common pathogens is ...

The dielectrophoretic collection spectra of antibiotic-sensitive and antibiotic-resistant strains of Staphylococcus epidermidis have been determined. These indicate that in the absence of antibiotic treatment there is a strong similarity between the dielectric properties of sensitive and resistant strains, and that there is a significant difference between the sensitive strains before and after...

During the past few decades, antibiotic-resistance of bacteria has assumed the proportion of a global crisis. The discovery of new antibiotics is not matching the rate of emergence of resistant strains thus narrowing the scope of chemotherapy. Notwithstanding the fact that emergence of resistance is facilitated by the use of antibiotics (Levy, 2002) exposure to antibiotics is not a pre-requisit...

Actinomycetes were characterized in terms of resistance to 11 different aminoglycoside antibiotics (AGs). Strains freshly isolated in AG containing media showed wide varieties of multiple AG resistance, while the majority of ISP (International Streptomyces Project) cultures and the actinomycete strains isolated in an AG free medium were susceptible to all or most of the AGs tested. Marked chara...

Three hundred and twenty nine strains of non-penicillinase-producing Neisseria gonorrhoeae (non-PPNG) isolated from men and women were tested for their susceptibility to a range of antibiotics, and were also auxotyped and serogrouped. Nearly 6% (18) of 312 strains tested were resistant to 1 mg/l or more penicillin (compared with 4.4% of PPNG strains isolated in 1981). Many (198, 64%) strains sh...

conclusions induction of coccoid form of p. aeruginosa may be one of the important reasons for antibiotic treatment failure; therefore, prescribed dose of antibiotics should be carefully managed to prevent increasing antibiotic resistance and coccoid bacteria induction. results all used antibiotics at sub mic concentration had capability to induce coccoid bacteria. the highest rate of induced c...

the purpose of this study was to determine the prevalence of anti-microbial resistance in intubated patients in intensive care unit (icu) of bahonar hospital in kerman province, iran during the year 2008. tracheal samples were obtained from 111 intubated patients in the icu by broncoalveolar lavage method. amikacin, ceftazidim and imipenem were used to evaluate antibiotic susceptibility. for de...

In studies of the interactions of antibacterial agents, it became important to try to elicit bacterial resistance to antibiotics in the experimental animal. Since this proved to be unexpectedly difficult, attention was directed to the process by which bacteria acquire resistance during exposure in vivo. The present paper is concerned with the incidence of streptomycin resistance in strains of s...
